Abstract
INTRODUCTION Renal stone is one of the common entities occurring in our population. There are different treatment modalities of stones; out of those percutaneous nephrolithotomy is one of the most popular and effective for the renal and upper tract stones. This study is based to compare the safety and efficacy of spinal anaesthesia and general anaesthesia in PCNL. METHODS In a randomized prospective study 60 patients were divided in two groups; group 1 (n=30) underwent PCNL in general anaesthesia and group 2 (n=30) underwent PCNL in spinal anaesthesia in prone position with the conventional technique. Demographic, operative data, post operative complications, patients' satisfaction rate and follow up complications were recorded and analyzed between two groups. RESULTS Mean age in group 1 was 39.10±12.45years and 36.10±14.18 in group 2 (P=0.100). Mean stone size in group 1 was 3.75±1.27cm and 3.23±1.36cm in group 2 (P=0.129).Similarly the operative time was 89.10 ± 49.38 min and 62.53±35.91 min in group 1 and group 2 respectively (P=0.042). There was no significant difference between the complications regarding the anaesthesia. Post operative nausea and vomiting were significantly higher in group 1 and headache in group 2 (p=<0.001). Overall patient satisfaction rate was higher in group 2 then in group 1 (p=0.01). Hospital stay in group 1 was 5.27±1.87 days and 4.53±1.88 days in group 2 (p = 0.07). Stone success rate was similar in each group (p =0.50). CONCLUSIONS Spinal anaesthesia is a safe and effective method in performing PCNL.

[PMID: 27458058 DOI: 10.1111/pace.12923] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Revised: 06/10/2016] [Accepted: 07/05/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND This is a comparative effectiveness study for cardiac resynchronization therapy defibrillator (CRT-D) therapy enabled by quadripolar (QUAD) versus bipolar (BIP) left ventricular (LV) leads. Heart failure (HF) hospitalization (HFH) rates, associated costs, and 30-day readmissions after index HFH were compared. METHODS Patients with de novo LV leads implanted as part of a CRT-D system between January 2011 and August 2013 with ≥1-year follow-up were included. Medical history, dates, and locations of HFH were collected thereafter. Patients were divided based on LV lead model: QUAD or BIP. Universal billing records (UB-04) for each HFH and ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) diagnoses/procedure codes were used to classify hospitalizations as HF or non-HF and calculate concurrent U.S. national-average medicare reimbursement. Rates, associated payer costs, and 30-day readmissions were then compared using nonparametric bootstrapping. RESULTS Baseline characteristics (N = 69 QUAD and N = 56 BIP) were similar. The inpatient HFH for the QUAD group (0.20/patient-year) was lower than the BIP group (0.31/patient-year, incidence rate ratio [IRR] = 0.62, P = 0.036). The overall HFH rate for the inpatient or outpatient setting for QUAD (0.29/patient-year) was lower than the BIP group (0.42/patient-year, IRR = 0.69, P = 0.055). Average cost of HFH in QUAD ($4,428/patient-year) was lower than BIP ($7,354/patient-year), a 39.8% cost reduction (P = 0.026). The 30-day readmission rate was also lower in QUAD compared to BIP (19% vs 28%, IRR = 0.68, P = 0.18). CONCLUSION This U.S. economic comparative study demonstrated that QUAD exhibited lower postimplant inpatient HFH rates and reduced healthcare utilization compared to BIP systems.

Abstract
BACKGROUND Chronic recurrent multifocal osteomyelitis (CRMO) is a little known inflammatory bone disease occurring primarily in children and adolescents. Delays in referral and diagnosis may lead to prolonged courses of antibiotics with in-patient care, unnecessary radiation exposure from multiple plain radiographs or bone scans and repeated surgery including bone biopsies. Children (aged < 18 years) diagnosed with CRMO between January 2005 and December 2012, reviewed at Bristol Royal Hospital for Children were included and all available data collected. Information regarding CRMO was sent to all orthopaedic surgeons in the region in 2009. The aim of the study was to examine the features of the cohort, to examine the length of time to diagnosis and to explore the criteria used for diagnosis with and without biopsy. FINDINGS Over an 8 year period, 41 patients were diagnosed with CRMO. Symptom onset occurred at a median of 9 years of age and time to diagnosis had a median of 15 months (range 0-92). Correlation coefficient analysis for time to diagnosis by year showed statistical significance with a decreasing trend. From the cohort data, diagnostic criteria were developed; applied retrospectively, 34 (83 %) children may have been diagnosed using the criteria, without a biopsy. CONCLUSIONS The data suggest that increasing knowledge of this condition may shorten time to diagnosis. Use of the Bristol diagnostic criteria by an experienced clinician may obviate the need for biopsy in some patients.

Abstract
T2K reports its first measurements of the parameters governing the disappearance of ν[over ¯]_{μ} in an off-axis beam due to flavor change induced by neutrino oscillations. The quasimonochromatic ν[over ¯]_{μ} beam, produced with a peak energy of 0.6 GeV at J-PARC, is observed at the far detector Super-Kamiokande, 295 km away, where the ν[over ¯]_{μ} survival probability is expected to be minimal. Using a data set corresponding to 4.01×10^{20} protons on target, 34 fully contained μ-like events were observed. The best-fit oscillation parameters are sin^{2}(θ[over ¯]_{23})=0.45 and |Δm[over ¯]_{32}^{2}|=2.51×10^{-3} eV^{2} with 68% confidence intervals of 0.38-0.64 and 2.26-2.80×10^{-3} eV^{2}, respectively. These results are in agreement with existing antineutrino parameter measurements and also with the ν_{μ} disappearance parameters measured by T2K.

Abstract
We have previously shown a novel antimetastatic role for neutrophils in the premetastatic lung of mice in models of breast cancer. Here we expand on those findings in the context of human breast cancer. We assessed the cytotoxicity of neutrophils from 90 newly diagnosed breast cancer patients, 24 ductal carcinoma in situ patients, 56 metastatic breast cancer patients, and 64 women with no history of cancer. We report that neutrophils from metastatic and newly diagnosed breast cancer patients are significantly more cytotoxic than neutrophils from cancer-free individuals. We hypothesized that tumor-secreted factors ‘prime’ neutrophils to become cytotoxic. To identify these factors we assayed for cytokines in serum from 54 breast cancer patients and 35 cancer-free controls. Tumor necrosis factor (TNFα), MCP-1 (CCL2), and IL1RA significantly correlated with cytotoxicity and directly stimulated neutrophil cytotoxicity ex vivo. RNA-seq analyses found protein kinase C iota (PRKCI) to be over expressed in patient neutrophils relative to neutrophils from cancer-free individuals. PRKCI has been implicated in NADPH oxidase assembly, required for neutrophil-mediated cell cytotoxicity. Treatment of human neutrophils with TNF-induced PRKCI expression and cytotoxicity in samples that had low basal levels of PRKCI expression. To date, this work is the first to demonstrate the cytotoxic role of neutrophils in the peripheral blood of a large cohort of breast cancer patients, and that select cytokines appear to mediate the stimulation of neutrophil cytotoxicity. Further functional studies are necessary to identify clinically relevant means of stimulating neutrophil cytotoxicity as an effective barrier against disease progression and metastasis.

Abstract
PURPOSE The prognosis of ipsilateral supraclavicular lymph node (SCLN) recurrence after early breast cancer appears to be worse than for other locoregional recurrences, but better than for distant metastases. Prophylactic radiotherapy (RT) to supraclavicular region decreases risk of ipsilateral SCLN recurrence. Currently, all patients with locally advanced breast cancer are considered high-risk for SCLN metastasis and treated with prophylactic RT. This study is carried out to identify risk factors associated with occult SCLN metastases in locally advanced breast cancer. MATERIALS AND METHODS Total 48 female patients of all ages presenting with locally advanced carcinoma of breast who were operable by protocol criteria were included in the study. All the patients underwent modified radical mastectomy with supraclavicular lymphnode dissection. The resected specimen was processed for the histopathological analysis. RESULTS Occult SCLN metastases are found in 25% (12/48) of the patients in this study. Eleven factors were identified and analyzed to know whether or not they are associated with SCLN metastasis. Of those only pathological N stage (7% for <pN3 vs and 52% for pN3 stage) and level axillary nodal involvement (7% for patients without Level III involvement and 52% for with Level III involvement) are significantly associated with high-risk for occult supraclavicular lymphnode metastasis. Other factors such as age, menopausal status, T stage, pathologic grade, lymphovascular invasion, extracapsular extension, hormone receptor, and Her2 neu receptor status are not associated with risk for SCLN metastasis. CONCLUSION Our study has shown that only high axillary disease burden in terms of more than 10 node positivity or more than 75% positive node out of total dissected nodes is associated with occult supraclavicular lymphnode metastasis breast cancer.

Abstract
BACKGROUND Postpartum sepsis accounts for most maternal deaths between three and seven days postpartum, when most mothers, even those who deliver in facilities, are at home. Case fatality rates for untreated women are very high. Newborns of ill women have substantially higher infection risk. METHODS/DESIGN The objectives of this study are to: (1) create, field-test and validate a tool for community health workers to improve diagnostic accuracy of suspected puerperal sepsis; (2) measure incidence and identify associated risk factors and; (3) describe etiologic agents responsible and antibacterial susceptibility patterns. This prospective cohort study builds on the Aetiology of Neonatal Infection in South Asia study in three sites: Sylhet, Bangladesh and Karachi and Matiari, Pakistan. Formative research determined local knowledge of symptoms and signs of postpartum sepsis, and a systematic literature review was conducted to design a diagnostic tool for community health workers to use during ten postpartum home visits. Suspected postpartum sepsis cases were referred to study physicians for independent assessment, which permitted validation of the tool. Clinical specimens, including urine, blood, and endometrial material, were collected for etiologic assessment and antibiotic sensitivity. All women with puerperal sepsis were given appropriate antibiotics. DISCUSSION This is the first large population-based study to expand community-based surveillance for diagnoses, referral and treatment of newborn sepsis to include maternal postpartum sepsis. Study activities will lead to development and validation of a diagnostic tool for use by community health workers in resource-poor countries. Understanding the epidemiology and microbiology of postpartum sepsis will inform prevention and treatment strategies and improve understanding of linkages between maternal and neonatal infections.

A model sample consisting of two different hydroxyapatite (hAp) powders was used as a bone phantom to investigate the extent to which X-ray diffraction tomography could map differences in hAp lattice constants and crystallite size. The diffraction data were collected at beamline 1-ID, the Advanced Photon Source, using monochromatic 65 keV X-radiation, a 25 × 25 µm pinhole beam and translation/rotation data collection. The diffraction pattern was reconstructed for each volume element (voxel) in the sample, and Rietveld refinement was used to determine the hAp lattice constants. The crystallite size for each voxel was also determined from the 00.2 hAp diffraction peak width. The results clearly show that differences between hAp powders could be measured with diffraction tomography.

Abstract
It had become a familiar routine. My seventh admission with diabetic ketoacidosis (DKA) in a year. Each time I was admitted it was the same; a DKA protocol, a diabetes specialist nurse visit, and a few questions from the doctors checking if "everything is okay?" On each admission, I would be discharged home after a couple of days. We all knew I'd be back again within a month or two.

Abstract
Genome engineering benefits from the availability of DNA modifying enzymes that have different target specificities and have optimized performance in different cell types. This variety of site-specific enzymes can be used to develop complex genome engineering applications at multiple loci. Although eight yeast site-specific tyrosine recombinases are known, only Flp is actively used in genome engineering. To expand the pool of the yeast site-specific tyrosine recombinases capable of mediating genome manipulations in mammalian cells, we engineered and analyzed variants of two tyrosine recombinases: R and TD. The activity of the evolved variants, unlike the activity of the native R and TD recombinases, is suitable for genome engineering in Escherichia coli and mammalian cells. Unexpectedly, we found that R recombinase benefits from the shortening of its C-terminus. We also found that the activity of wild-type R can be modulated by its non-consensus "head" sequence but this modulation became not apparent in the evolved R variants. The engineered recombinase variants were found to be active in all recombination reactions tested: excision, integration, and dual recombinase-mediated cassette exchange. The analysis of the latter reaction catalyzed by the R/TD recombinase pair shows that the condition supporting the most efficient replacement reaction favors efficient TD-mediated integration reaction while favoring efficient R-mediated integration and deletion reactions.

Abstract
Isotopic enrichment of biomacromolecules is a widely used technique that enables the investigation of the structural and dynamic properties to provide information not accessible with natural abundance isotopic composition. This study reports an approach for deuterium incorporation into bacterial cellulose. A media formulation for growth of Acetobacter xylinus subsp. sucrofermentans and Gluconacetobacter hansenii was formulated that supports cellulose production in deuterium (D) oxide. The level of D incorporation can be varied by altering the ratio of deuterated and protiated glycerol used during cell growth in the D2O-based growth medium. Spectroscopic analysis and mass spectrometry show that the level of deuterium incorporation is high (>90%) for the perdeuterated form of bacterial cellulose. The small-angle neutron scattering profiles of the cellulose with different amounts of D incorporation are all similar indicating that there are no structural changes in the cellulose due to substitution of deuterium for hydrogen. In addition, by varying the amount of deuterated glycerol in the media it was possible to vary the scattering length density of the deuterated cellulose. The ability to control deuterium content of cellulose extends the range of experiments using techniques such as neutron scattering to reveal information about the structure and dynamics of cellulose, and its interactions with other biomacromolecules as well as synthetic polymers used for development of composite materials.

Abstract
Management of the mobile elderly patient who sustains an intra-capsular neck of femur fracture remains controversial. Current evidence is mixed as to whether total hip arthroplasty (THA), which confers higher surgical and dislocation risk, is significantly superior in function and in reduced rates of reoperation when compared to bipolar hemi-arthroplasty. A group of 110 patients with an intra-capsular NOF fracture who had undergone either THA or Bipolar hemi-arthroplasty and were still alive at the time of follow up were retrospectively identified and matched using the National Hip Fracture Database. Matching criteria included ASA, age, sex, pre-op mobility, pre-op AMTS and source of admission. Follow up was by postal questionnaire. Mean follow up was 24 months in both groups (Range; Bipolar 12-36 months, THA 12-38 months). There was no significant difference in pre-operative Tonnis grade, postoperative Oxford Hip Score (OHS) or Short Form 36 (SF-36) scores between the two groups. 12 dislocations in 5 patients occurred in the THA group and none in the bipolar group. 33/55 Bipolar patients were discharged to their own home compared to 35/55 in the THA group. None of the bipolar hemi-arthroplasties were revised to THA. Higher complication rates were experienced in the THA group with no increase in function.

Abstract
Soon after the discovery of deuterium, efforts to utilize this stable isotope of hydrogen for labeling of plants began and have proven successful for natural abundance to 20% enrichment. However, isotopic labeling with deuterium ((2)H) in higher plants at the level of 40% and higher is complicated by both physiological responses, particularly water exchange through transpiration, and inhibitory effects of D2O on germination, rooting, and growth. The highest incorporation of 40-50% had been reported for photoheterotrophic cultivation of the duckweed Lemna. Higher substitution is desirable for certain applications using neutron scattering and nuclear magnetic resonance (NMR) techniques. (1)H(2)H NMR and mass spectroscopy are standard methods frequently used for determination of location and amount of deuterium substitution. The changes in infrared (IR) absorption observed for H to D substitution in hydroxyl and alkyl groups provide rapid initial evaluation of incorporation. Short-term experiments with cold-tolerant annual grasses can be carried out in enclosed growth containers to evaluate incorporation. Growth in individual chambers under continuous air perfusion with dried sterile-filtered air enables long-term cultivation of multiple plants at different D2O concentrations. Vegetative propagation from cuttings extends capabilities to species with low germination rates. Cultivation in 50% D2O of annual ryegrass and switchgrass following establishment of roots by growth in H2O produces samples with normal morphology and 30-40% deuterium incorporation in the biomass. Winter grain rye (Secale cereale) was found to efficiently incorporate deuterium by photosynthetic fixation from 50% D2O but did not incorporate deuterated phenylalanine-d8 from the growth medium.

Abstract
OBJECTIVES The aim of the study was to identify differences in infant outcomes, virological efficacy, and preterm delivery (PTD) outcome between women exposed to lopinavir/ritonavir (LPV/r) and those exposed to atazanavir/ritonavir (ATV/r). METHODS A retrospective case note review was carried out. The case notes of 493 women who conceived while on LPV/r or ATV/r or initiated LPV/r or ATV/r during pregnancy and who delivered between 1 September 2007 and 30 August 2012 were reviewed. Data collected included demographics, antiretroviral use, HIV markers, and pregnancy and infant outcomes. Infant outcomes, virological efficacies and PTD rates for LPV/r and ATV/r were compared. RESULTS A total of 306 women received LPV/r (82 conceiving while on the drug and 224 commencing it post-conception) and 187 received ATV/r (96 conceiving while on the drug and 91 commencing it post-conception). Comparing the two protease inhibitors (PIs), viral suppression rates were similar and, in women starting antiretroviral therapy (ART) post-conception, the median times to first undetectable HIV viral load were not significantly different (P = 0.64). PTD rates did not differ by therapy overall (ATV/r, 13%; LPV/r, 14%) or when considering the timing of first exposure (conceiving on ART, P = 0.81; commencing ART in pregnancy, P = 0.08). Poor fetal outcomes were very uncommon. There were two transmissions, giving a mother-to-child transmission (MTCT) rate of 0.4% (95% confidence interval 0.05-1.5%). CONCLUSIONS Both ART regimens were well tolerated and successful in preventing MTCT. No significant differences in tolerability or in pregnancy or infant outcomes were observed, which supports the provision of a choice of PI in pregnancy.

Abstract
Genome engineering relies on DNA-modifying enzymes that are able to locate a DNA sequence of interest and initiate a desired genome rearrangement. Currently, the field predominantly utilizes site-specific DNA nucleases that depend on the host DNA repair machinery to complete a genome modification task. We show here that genome engineering approaches that employ target-specific variants of the self-sufficient, versatile site-specific DNA recombinase Flp can be developed into promising alternatives. We demonstrate that the Flp variant evolved to recombine an FRT-like sequence, FL-IL10A, which is located upstream of the human interleukin-10 gene, and can target this sequence in the model setting of Chinese hamster ovary and human embryonic kidney 293 cells. This target-specific Flp variant is able to perform the integration reaction and, when paired with another recombinase, the dual recombinase-mediated cassette exchange reaction. The efficiency of the integration reaction in human cells can be enhanced by 'humanizing' the Flp variant gene and by adding the nuclear localization sequence to the recombinase.

Abstract
The bioenergy crop switchgrass was grown hydroponically from tiller cuttings in 50 % D 2 O to obtain biomass with 34 % deuterium substitution and physicochemical properties similar to those of H 2 O-grown switchgrass controls. Deuterium enrichment of biological materials can potentially enable expanded experimental use of small angle neutron scattering (SANS) to investigate molecular structural transitions of complex systems such as plant cell walls. Two key advances have been made that facilitate cultivation of switchgrass, an important forage and biofuel crop, for controlled isotopic enrichment: (1) perfusion system with individual chambers and (2) hydroponic growth from tiller cuttings. Plants were grown and maintained for several months with periodic harvest. Photosynthetic activity was monitored by measurement of CO2 in outflow from the growth chambers. Plant morphology and composition appeared normal compared to matched controls grown with H2O. Using this improved method, gram quantities of switchgrass leaves and stems were produced by continuous hydroponic cultivation using growth medium consisting of basal mineral salts in 50 % D2O. Deuterium incorporation was confirmed by detection of the O-D and C-D stretching peaks with FTIR and quantified by (1)H- and (2)H-NMR. This capability to produce deuterated lignocellulosic biomass under controlled conditions will enhance investigation of cell wall structure and its deconstruction by neutron scattering and NMR techniques.

Abstract
INTRODUCTION Up to 15% of patients with cardiothoracic trauma require emergency surgery, and death can be prevented in a substantial proportion of this group. UK reports have emphasised the need for improvement in this field. We assessed major cardiothoracic trauma (MCT) outcomes in North West England over 11 years. METHODS The database from the Trauma Audit and Research Network was used to retrieve data for all patients who had suffered MCT between 2000 and 2011 in North West England and the findings analysed. Trauma that led to thoracotomy/thoracoscopy or sternotomy was defined as MCT. RESULTS A total of 146 patients were identified, and a considerable male predominance (88.4%) noted. A total of 54.1% had sustained penetrating cardiothoracic trauma. Also, 53.4% had been admitted to tertiary-care hospitals for trauma (TCHT) and 46.6% had been admitted to non-TCHT. Overall prevalence of mortality was 35.6%. No significant difference was found in mortality between TCHT vs non-TCHT. Prevalence of mortality was significantly higher in the subgroup of patients cared for exclusively in non-TCHT compared with patients transferred from non-TCHT to TCHT (41% vs 13.8%, p<0.05). CONCLUSIONS No significant difference was demonstrated in length of stay in hospital/length of stay in the intensive treatment unit and prevalence of mortality between patients originally presenting in TCHT and those presenting in non-TCHT. However, patients transferred from non-TCHT to TCHT had a lower prevalence of mortality. These findings may constitute a valuable benchmark for comparison with results arising after introduction of trauma centres in the UK.

Abstract
Background: Periapical lesions occur in response to chronic irritation in periapical tissue, generally resulting from an infected root canal. Specific etiological agents of induction, participating cell population and growth factors associated with maintenance and resolution of periapical lesions are incompletely understood. Among the cells found in periapical lesions, mast cells have been implicated in the inflammatory mechanism. Aim: Quantifications and the possible role played by mast cells in the periapical granuloma and radicular cyst. Hence, this study is to emphasize the presence (localization) and quantification of mast cells in periapical granuloma and radicular cyst. Materials and Methods: A total of 30 cases and out of which 15 of periapical granuloma and 15 radicular cyst, each along with the case details from the previously diagnosed cases in the department of oral pathology were selected for the study. The gender distribution showed male 8 (53.3%) and females 7 (46.7%) in periapical granuloma cases and male 10 (66.7%) and females 5 (33.3%) in radicular cyst cases. The statistical analysis used was unpaired t-test. Results: Mean mast cell count in periapical granuloma subepithelial and deeper connective tissue, was 12.40 (0.99%) and 7.13 (0.83%), respectively. The mean mast cell counts in subepithelial and deeper connective tissue of radicular cyst were 17.64 (1.59%) and 12.06 (1.33%) respectively, which was statistically significant. No statistical significant difference was noted among males and females. Conclusion: Mast cells were more in number in radicular cyst. Based on the concept that mast cells play a critical role in the induction of inflammation, it is logical to use therapeutic agents to alter mast cell function and secretion, to thwart inflammation at its earliest phases. These findings may suggest the possible role of mast cells in the pathogenesis of periapical lesions.

Abstract
BACKGROUND Promising results were reported with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in peritoneal carcinomatosis. Experiences in India are not published. This is a preliminary report. MATERIALS AND METHODS From eight patients with peritoneal metastasis, six patients (5 M, 1 F), aged (40-62 years) were treated with CRS and HIPEC between May 2010 and August 2011 from a single institution. Three had Mucinous Adenocarcinoma of Appendix and one each with Mesothelioma, Ovarian Cancer and Colonic Cancer. Four were earlier treated with systemic chemotherapy and recurred. Pre-operative peritoneal cancer index (PCI) was calculated based on recent computerized tomography or positron emission tomography scans. Surgical completeness cytoreduction score (CCS) was classified as macroscopically complete (CCS-0); optimal residual disease ≤2.5 mm in any region (CCS-1); or grossly incomplete: Residual disease >2.5 mm (CCS-2) or >25 mm (CCS-3). They were treated by closed perfusion technique with mitomycin-C (MCC) and cisplatin at 41-42°C, for 60 min. RESULTS Optimal cytoreduction (residual tumor nodules <2.5 mm i.e. CC0 and CC1) was performed in four patients (66.67%). There was no operative mortality or Grade 3 and 4 toxicity. Patients with PCI <11 are alive without recurrence with overall survival of 26-31 months. Those with PCI >11 had recurrence with overall survival of 3-19 months. Two patients died at 3 and 9 months. CONCLUSION CRS and HIPEC is a promising therapeutic option in selected patients with peritoneal carcinomatosis. These results in six patients are preliminary but encouraging. Patient with low PCI had better disease free survival.
