Abstract
Essentials Microbe-dependent production of trimethylamine N-oxide (TMAO) contributes to thrombosis risk. The impact of host flavin monooxygenase 3 (FMO3) modulation on platelet function is unknown. Genetic manipulation of FMO3 in mice alters systemic TMAO levels and thrombosis potential. Genetic manipulation of FMO3 is associated with alteration of gut microbial community structure. SUMMARY Background Gut microbes play a critical role in the production of trimethylamine N-oxide (TMAO), an atherogenic metabolite that impacts platelet responsiveness and thrombosis potential. Involving both microbe and host enzymatic machinery, TMAO generation utilizes a metaorganismal pathway, beginning with ingestion of trimethylamine (TMA)-containing dietary nutrients such as choline, phosphatidylcholine and carnitine, which are abundant in a Western diet. Gut microbial TMA lyases use these nutrients as substrates to produce TMA, which upon delivery to the liver via the portal circulation, is converted into TMAO by host hepatic flavin monooxygenases (FMOs). Gut microbial production of TMA is rate limiting in the metaorganismal TMAO pathway because hepatic FMO activity is typically in excess. Objectives FMO3 is the major FMO responsible for host generation of TMAO; however, a role for FMO3 in altering platelet responsiveness and thrombosis potential in vivo has not yet been explored. Methods The impact of FMO3 suppression (antisense oligonucleotide-targeting) and overexpression (as transgene) on plasma TMAO levels, platelet responsiveness and thrombosis potential was examined using a murine FeCl3 -induced carotid artery injury model. Cecal microbial composition was examined using 16S analyses. Results Modulation of FMO3 directly impacts systemic TMAO levels, platelet responsiveness and rate of thrombus formation in vivo. Microbial composition analyses reveal taxa whose proportions are associated with both plasma TMAO levels and in vivo thrombosis potential. Conclusions The present studies demonstrate that host hepatic FMO3, the terminal step in the metaorganismal TMAO pathway, participates in diet-dependent and gut microbiota-dependent changes in both platelet responsiveness and thrombosis potential in vivo.

Abstract
BACKGROUND Adenocarcinoma is the most prevalent histological type of lung cancer (LC) in developed countries while squamous cell carcinoma (SqCC) has so far been the most common type at our center. Herein, we report our continued assessment of the epidemiological trend of LC aimed at determining any change in the histological distribution. METHODS Retrospective analysis involving all consecutive newly diagnosed LC patients over a 4-year period (March 2011-February 2015). Demographic characteristics, histology, and staging data for current data set were compared with our previously published data (2008-2011). As before, smoking index (SI) was used to group patients as never (SI = 0), light (SI = 1-100), moderate (SI = 101-300), and heavy (SI ≥301) smokers. RESULTS Majority of 1301 patients had advanced disease (Stages IIIB = 30.1%; IV = 53.3%), were males (82.3%) and current/ex-smokers (76.9%). Adenocarcinoma and SqCC (36.4% each) were equally prevalent. As compared to our previous study, adenocarcinoma increased (36.4% vs. 27.5%) and nonsmall cell lung cancer-not otherwise specified (NSCLC-NOS) decreased (5.1% vs. 10.9%) significantly (P < 0.001). The current study had more heavy smokers (68.3% vs. 61.1%; P = 0.013) and median SI was also higher (500 vs. 400; P = 0.001). Among SI-based groups, significant differences were observed for age, gender, body mass index, histology, TNM stage, and metastatic disease distribution. CONCLUSION Reduction in NSCLC-NOS has led to adenocarcinoma and SqCC being equally prevalent at our center in North India despite an increase in heavy smokers. Accurate histological NSCLC subtyping is necessary for optimal epidemiological assessment.

Abstract
Abstract
Pan-cancer studies of somatic copy number alterations (SCNAs) have demonstrated shared SCNAs across cancer types, but whether these shared SCNAs vary by race-ethnicity has not been explored. Utilizing data from The Cancer Genome Atlas (TCGA), we identified SCNAs in breast and prostate tumors, two cancers with racially-disparate outcomes, and then tested for differences in SCNA magnitude by self-reported African American and European American race-ethnicity, as well as by regional chromosomal African ancestry within African Americans. GISTIC2 was applied to high density SNP array data to map SCNA regions in 712 European and 174 African American female breast tumors and 267 European and 42 African American prostate tumors derived from the TCGA dataset. For each tumor, SCNA magnitude was quantified by the area under the logarithm-base 2 copy number curve, and the germline ancestral origin of SCNAs was inferred using RFMix. A linear model was used to assess the association between SCNA magnitude and race-ethnicity (or regional African ancestry) while adjusting age-at-diagnosis and tumor severity. Race-differentiated SCNAs common to breast and prostate were found at chromosomes 5q11-21, 6q12-14, 6q16-22, 8q21-24, 11q22, 13q12-21, and 16q21-24, with 8q21-24 being the only amplification. African American breast and prostate tumors had higher magnitude alterations in the regions on 5q11-21, 8q21-24, 11q22, and 13q12-21, and among African Americans, this higher magnitude at 8q21-24 and 13q12-21 was consistent with increasing regional African ancestry. Within these regions with higher magnitude SCNAs in African Americans, expression analysis revealed 18 cancer genes, including RB1 and PVT1, differentially expressed by race-ethnicity in both tumors types that were consistent with the observed SCNA differences. While differences in SCNAs by race-ethnicity have been studied in single cancers, this is the first study to identify race-differentiated SCNAs shared by two hormonally-driven cancers and to explore the potential of germline genetic ancestry as a mechanism leading to this differentiation. The differentially expressed genes within SCNAs common to both tumor types could provide further insight into the racially disparate outcomes in breast and prostate cancers.

Association between cadmium and androgen receptor protein expression differs in prostate tumors of African American and European American men. J Trace Elem Med Biol 2018; 48:233-238.

Abstract
Cadmium is a known carcinogen that has been implicated in prostate cancer, but how it affects prostate carcinogenesis in humans remains unclear. Evidence from basic science suggests that cadmium can bind to the androgen receptor causing endocrine disruption. The androgen receptor is required for normal prostate development and is the key driver of prostate cancer progression. In this study, we examined the association between cadmium content and androgen receptor protein expression in prostate cancer tissue of African American (N = 22) and European American (N = 30) men. Although neither overall tumor cadmium content (log transformed) nor androgen receptor protein expression level differed by race, we observed a race-cadmium interaction with regard to androgen receptor expression (P = 0.003) even after accounting for age at prostatectomy, smoking history, and Gleason score. African American men had a significant positive correlation between tumor tissue cadmium content and androgen receptor expression (Pearson correlation = 0.52, P = 0.013), while European Americans showed a non-significant negative correlation between the two (Pearson correlation = -0.19, P = 0.31). These results were unchanged after further accounting for tissue zinc content or dietary zinc or selenium intake. African American cases with high-cadmium content (>median) in tumor tissue had more than double the androgen receptor expression (0.021 vs. 0.008, P = 0.014) of African American men with low-cadmium level. No difference in androgen receptor expression was observed in European Americans by cadmium level (high 0.015 vs. low 0.011, P = 0.30). Larger studies are needed to confirm these results and if upheld, determine the biologic mechanism by which cadmium increases androgen receptor protein expression in a race-dependent manner. Our results suggest that cadmium may play a role in race disparities observed in prostate cancer.

Abstract
Bone marrow derived mesenchymal stromal cells have been shown to have significant therapeutic effects in experimental models of pneumonia and lung injury. The current study examined the roles of the toll like receptor 4 (TLR4) and protease activated receptor 1 (PAR1) pathways on mesenchymal stromal cell (MSC) survival and therapeutic activity in a murine model of pneumonia. MSCs from TLR4 -/- and R41Q-PAR1 mutated mice were isolated to test the effect of mutating these specific pathways on MSC survival when exposed to cytotoxic stimuli in vitro. An Escherichia coli pneumonia model was used to assess the effect of these specific pathways on MSC therapeutic activity in vivo. Our results showed that mutation of either the TLR4 or PAR1 pathways in MSCs impaired cell survival under conditions of inflammatory stress in vitro, and eliminated their therapeutic efficacy in vivo. Also, stimulation of the TLR4 pathway on MSCs led to secretion of low levels of prothrombin by MSCs, while disrupting the TLR4 pathway impaired canonical signaling through PAR1 in response to thrombin. Therefore, this study demonstrates that both TLR4 and PAR1 are required for MSC survival under inflammatory conditions in vitro and therapeutic capacity in vivo, and that the TLR4 pathway regulates signaling through PAR1 on MSCs.

Abstract
INTRODUCTION The objective of this study was to conduct a formative evaluation of a teledentistry (TD) programme that was developed for a predominantly rural state in the Midwestern United States. MATERIALS AND METHODS Formative evaluation data were collected on programme activities from the TD programme records. In addition, the effectiveness of the TD training programme was evaluated using a self-administered paper-based survey administered to the participants, immediately following completion of the training activity. Ninety-three dental students, oral health and other health professionals participated in the TD training programme. RESULTS Overall, the trainees rated the TD training programme highly, with regard to the content, format and skills improvement. The evaluation also demonstrated a positive change in all trainees' attitudes following the training sessions, with most trainees acknowledging a positive impact of the training on their knowledge and competency. DISCUSSION AND CONCLUSIONS We identified challenges in the development of the TD programme and in expanding access to oral health care for rural communities. Challenges included reimbursement and a limited interest amongst established dental offices. Dental schools can play an important role in preparing both dental health professionals and other health professionals in the use of TD by providing training and oral health expertise. The use of TD by non-dental providers for consultation, referral and disease management has the potential to improve oral health outcomes, particularly for rural and underserved populations. Evaluation data provide critical feedback to programme planners and administrators.

Abstract
Background Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major
health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following:
• Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy
with small diameter endoscopes.
• Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability.
• Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour
threshold, and/or one of odour identification or discrimination.
• Comprehensive chemosensory assessment should include gustatory screening.
• Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
Increase in sympathetic activity as a result of cardiovascular stress response to laryngoscopy can be detrimental to the patient. The primary objective is to compare intravenous dexmedetomidine and clonidine as adjuvants to low dose opioid (fentanyl) for attenuation of hemodynamic response to laryngoscopy and tracheal intubation. The secondary objectives are to compare the perioperative dose requirement of fentanyl and thiopentone, to compare the duration of postoperative analgesia, and to look for side effects in all three groups. This randomized controlled trial was performed in a tertiary care hospital in North India from November 2012 to April 2014. One hundred twenty (120) patients (ASA I or II) posted for elective surgery under general anesthesia. Group D received intravenous dexmedetomidine (1μg/kg) with intravenous fentanyl (1μg/kg), Group C received intravenous clonidine (1μg/kg) with intravenous fentanyl (1μg/kg) and Group F received intravenous fentanyl (2μg/kg). Heart rate and mean arterial pressure were recorded at baseline, after study drug at 5, 10 & 15 minutes, after induction, intubation (0 min) and 1, 3, 5, 10, 15 minutes after intubation. The required perioperative doses of thiopentone and fentanyl, and time to first rescue analgesia given in postoperative period were also noted. One way ANOVA and Repeated Measures ANOVA followed by multiple comparisons (if applicable) were used for data analysis. P value <0.05 was considered statistically significant. The rise in HR and MAP at laryngoscopy and intubation was found to be less in clonidine group as compared to fentanyl group and dexmedetomidine was able to abolish this rise completely. The requirement of thiopentone and fentanyl were significantly least in dexmedetomidine group and the duration of time to first rescue analgesia was significantly prolonged in clonidine group. Intravenous fentanyl (2μg/kg) failed, addition of clonidine to fentanyl was able to partially blunt it, but the addition of dexmedetomidine to fentanyl completely abolished the hemodynamic response to laryngoscopy and intubation.

Abstract
A Atherosclerosis-related cardiovascular disease remains an important cause of morbidity and mortality in renal transplant patients. We assessed the efficacy and safety of the newer synthetic HMG-CoA reductase inhibitor, fluvastatin, in 12 renal transplant patients who remained hypercholesterolemic, despite having been on the American Heart Association (AHA) Step I diet for 6 weeks. At 8 weeks, compared to the control phase, fluvastatin therapy, 20 mg/day, reduced the total cholesterol (TC) from 321 ± 57 [± SD] to 301 ± 123 mg/dl (p=0.3); low-density lipoprotein cholesterol (LDL-C), from 209 ± 56 to 176 ± 81 mg/dl (p=0.2); and the triglyceride (TG) levels from 343 ± 119 to 277 ± 117 mg/dl (p=0.06); all these changes were statistically insignificant. However, the therapy significantly increased the high-density lipoprotein cholesterol (HDL-C) from 37 ± 11 to 46 ± 13 mg/dl (p=0.006). During this short-term treatment period no adverse biochemical effects were noted with the therapy.

Abstract
Abstract
Background: Accelerated partial breast irradiation (APBI) delivers adjuvant radiation (RT) to the 1-2 cm of the breast at highest risk for recurrence surrounding the lumpectomy (L) cavity over 5-8 days and is an alternative to standard whole breast irradiation for hormone sensitive (HS) stage 1 (T1, N0) breast cancer (BC) based on 2 randomized controlled trials. External beam methods for APBI are common but have notable inherent drawbacks that include: inter-fraction inaccuracy due to patient setup based on anatomy, intra fraction error related to patient or respiratory motion, and inaccurate geometric targeting by relying on L cavity position instead of the tumor position. Postoperative RT has other limitations including delivery in the setting of disrupted blood or lymphatic supply that may be suboptimal for radio sensitivity and it eliminates observation of radiation-induced tumor response. MRI is an established tool for measuring BC extent and response from neoadjuvant systemic therapy. It's hypothesized that MRI directed pre-operative APBI using intensity modulated radiotherapy (IMRT) with image guidance (IGRT) will improve RT delivery, and that MRI features can be identified to correlate with pathologic radiation response.
Trial Design: There are 2 cohorts to this single arm prospective trial. The first cohort is for establishing and verifying patient flow and image fusion between MRI, CT and RT planning. In the second cohort eligible patients will receive preoperative APBI 38.5 Gy in 10 fractions BID with IMRT, IGRT in the prone position using MRI defined targets fused to CT treatment planning.
Eligibility: For cohort 1 it is HS Stage 1 BC that has completed CT in prone position for RT planning. Eligibility for cohort 2 requires: age > 50 yo, clinical stage 1 BC, HS, HER2 negative, intending L, clinically negative axilla verified by ultrasound, able to tolerate the prone position, and MRI with contrast.
Specific aims: To determine the reproducibility of MRI directed preoperative APBI based on meeting 3 criteria: ability to define RT targets by MRI, quality of RT plans and completion of treatment (APBI and surgery). Additional aims include assessing toxicity, cosmetic outcome, local regional cancer control and collection of tissue for correlative studies.
Statistical methods: The optimal two-stage design by Simon is used. Sample size for cohort 2 is based on the first endpoint. 19 eligible patients will be required in the first stage; if 3 or more treatments are scored unacceptable, then early stopping will be recommended. Otherwise, accrual will continue to a total accrual of 30. If > 4 of 30 treatments are scored unacceptable, the technique will be considered not reproducible, and a Phase II study will not be pursued. Under the null hypothesis of an 80% reproducibility rate, this two-stage design has an expected sample size of 24.4.
Patient accrual to cohort 1 has completed the targeted accrual of 3. Patient accrual to Cohort 2 is 5/30.

Abstract
Abstract
Background: In women amenable to breast conserving therapy, lumpectomy followed by adjuvant whole breast irradiation (WBI) remains the standard of care. Randomized trials have demonstrated that the addition of a lumpectomy cavity boost significantly reduces the risk of ipsilateral breast tumor recurrences but also increases the risk of breast fibrosis. Contemporary randomized trials define the lumpectomy cavity boost volume as a 1.7 cm isometric expansion on the lumpectomy cavity as delineated on CT. However, identifying the lumpectomy cavity can be challenging, especially in women that receive adjuvant chemotherapy and in cases in which surgical clips are not present. Recently, the use of oncoplastic techniques in breast conserving surgery has increased. These techniques are used to prevent the poor cosmetic results that can occur when a large volume of breast tissue is resected. Women that undergo oncoplastic reconstruction represent especially difficult cases for lumpectomy cavity delineation. Retrospective series have evaluated the use of intraoperative electron radiotherapy (IOERT) as a boost prior to WBI in women receiving lumpectomy without oncoplastic reconstruction. In the largest series of IOERT boost prior to WBI the local control rate of this approach was >99%. Prospective data regarding IOERT boost in women undergoing oncoplastic reconstruction are limited. Advantages of this approach include direct visualization/irradiation of the tumor bed, sparing the skin of irradiation, and reducing the treatment time by ˜1 week. We hypothesize that IOERT boost followed by WBI will result in acceptably low rates of grade 3 fibrosis in women undergoing lumpectomy with oncoplastic reconstruction.
Trial Design: This is a single-arm, prospective study to evaluate the safety, toxicity and efficacy of IOERT boost at the time of breast conserving surgery in women with early-stage breast cancer undergoing oncoplastic reconstruction. Eligible women will receive 1 dose of 8 Gy to the surgical bed after lumpectomy but prior to oncoplastic reconstruction. Women will then receive adjuvant WBI of 40 Gy in 15 fractions or 50 Gy in 25 fractions.
Eligibility: Key inclusion criteria include age≥18 yo, clinically node-negative stage I/II, any breast cancer subtype.
Specific Aims: Our primary aim is to determine the rate of grade 3 breast fibrosis at 1 year. Additional aims include surgical complication rates, cosmesis, and local regional cancer control.
Statistical Methods: Safety will be evaluated by the rate of surgical complications necessitating hospital readmission or return to the operating room within 30 days of surgery+IOERT. If ≥4 events in the first 10 patients, ≥7 events in the first 20 patients, or ≥9 events in the first 30 patients are seen, the study will be halted. We hypothesize that the grade 3 fibrosis rate in our study will be ≤5%. Assuming an actual rate of 4%, an unacceptable rate of 9%, and a drop-out rate of 10%, the expected sample size is 176.
Patient Accrual: Current accrual is 0 of 176.

Conventional vs virtual autopsy with postmortem MRI in phenotypic characterization of stillbirths and fetal malformations. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 51:236-245. [PMID: 28295775 DOI: 10.1002/uog.17468] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Revised: 01/25/2017] [Accepted: 02/28/2017] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To compare virtual autopsy using postmortem magnetic resonance imaging (MRI) with conventional autopsy with respect to phenotypic characterization of stillbirths and malformed fetuses, and acceptability to parents. METHODS This was a prospective diagnostic evaluation study, conducted from June 2013 to June 2015, including stillbirths and pregnancies terminated owing to fetal malformation at ≥ 20 weeks' gestation, for which parental consent to both conventional autopsy and postmortem MRI was obtained. Cases of maternal and obstetric cause of fetal demise were excluded. Whole-body postmortem MRI (at 1.5 T) was performed prior to conventional autopsy. Taking conventional autopsy as the diagnostic gold standard, postmortem MRI findings alone, or in conjunction with other minimally invasive prenatal and postmortem investigations, were assessed and compared for diagnostic accuracy. RESULTS Parental consent for both conventional autopsy and postmortem MRI was obtained in 52 cases of which 43 were included in the analysis. In 35 (81.4%) cases, the final diagnosis based on virtual autopsy with postmortem MRI was in agreement with that of conventional autopsy. With conventional autopsy as the reference standard, sensitivity, specificity, positive and negative predictive values of postmortem MRI were, respectively: 77.7%, 99.8%, 97.4% and 98.0% for whole-body assessment; 93.1%, 99.0%, 87.1% and 99.5% for the nervous system; 61.0%, 100.0%, 100.0% and 96.7% for the cardiovascular system; 91.1%, 100.0%, 100.0% and 98.0% for the pulmonary system; 80.6%, 99.8%, 96.7% and 98.7% for the abdomen; 96.2%, 99.7%, 96.2% and 99.7% for the renal system; and 66.7%, 100.0%, 100.0% and 97.2% for the musculoskeletal system. Virtual autopsy was acceptable to 96.8% of families as compared with conventional autopsy to 82.5%. CONCLUSIONS Virtual autopsy using postmortem MRI and other minimally invasive investigations can be an acceptable alternative to conventional autopsy when the latter is refused by the parents. Postmortem MRI is more acceptable to parents and can provide additional diagnostic information on brain and spinal cord malformations. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
AIMS To further characterise biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC. METHODS AND RESULTS We identified 28 tumours from multiple institutions. They typically showed two cell populations-larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm. The dual morphology was variable (median 72.5% of tumour, range 5-100%); emperipolesis was found in all cases. The male/female ratio was 2:1, and the median age was 55 years (range 39-86 years). The median tumour size was 20 mm (range 9-65 mm). Pathological stage pT1a was found in 21 cases, pT1b in three, and pT3a and pT3b in one each (two not available). Multifocality was found in 32%: multifocal biphasic RCC in one case, biphasic + papillary RCC in two cases, biphasic + clear cell RCC in three cases, biphasic + low-grade urothelial carcinoma of the renal pelvis in one case, and biphasic + Birt-Hogg-Dubé syndrome in one case. Positive immunostains included: PAX8, cytokeratin (CK) 7, α-methylacyl-CoA racemase, epithelial membrane antigen, and vimentin. Cyclin D1 was expressed only in the larger cells. The Ki67 index was higher in the larger cells (median 5% versus ≤1%). Negative stains included: carbonic anhydrase 9, CD117, GATA-3, WT1, CK5/6, and CK20; CD10 and 34βE12 were variably expressed. Gains of chromosomes 7 and 17 were found in two evaluated cases. Follow-up was available for 23 patients (median 24 months, range 1-244 months): 19 were alive without disease, one was alive with recurrence, and one had died of disease (two had died of other causes). CONCLUSIONS Biphasic papillary RCC is a rare variant of papillary RCC, and is often multifocal.

Abstract
In the past few years, measurement of drug release from pharmaceutical dosage forms has been a focus of extensive research because the release profile obtained in vitro can give an indication of the drug's performance in vivo. Currently, there are no compendial in vitro release methods designed for liposomes owing to a range of experimental challenges, which has created a major hurdle for both development and regulatory acceptance of liposome-based drug products. In this paper, we review the current techniques that are most often used to assess in vitro drug release from liposomal products; these include the membrane diffusion techniques (dialysis, reverse dialysis, fractional dialysis, and microdialysis), the sample-and-separate approach, the in situ method, the continuous flow, and the modified United States Pharmacopeia methods (USP I and USP IV). We discuss the principles behind each of the methods and the criteria that assist in choosing the most appropriate method for studying drug release from a liposomal formulation. Also, we have included information concerning the current regulatory requirements for liposomal drug products in the United States and in Europe. In light of increasing costs of preclinical and clinical trials, applying a reliable in vitro release method could serve as a proxy to expensive in vivo bioavailability studies. Graphical Abstract Appropriate in-vitro drug release test from liposomal products is important to predict the in-vivo performance.

Abstract
SETTING In 2007, the Rwandan Ministry of Health, with support from Partners In Health, introduced a district-level non-communicable disease programme that included asthma care. OBJECTIVE To describe the demographics, management and 24-month outcomes of asthma patients treated at three rural district hospitals in Rwanda. DESIGN We retrospectively reviewed electronic medical records of asthma patients enrolled from January 2007 to December 2012, and extracted information on demographics, clinical variables and 24-month outcomes. RESULTS Of the 354 patients, 66.7% were female and 41.5% were aged between 41 and 60 years. Most patients (53.1%) were enrolled with moderate persistent asthma, 40.1% had mild persistent asthma and 6.8% had severe persistent asthma. Nearly all patients (95.7%) received some type of medication, most commonly a bronchodilator. After 24 months, 272 (76.8%) patients were still alive and in care, 21.1% were lost to follow-up, 1.7% had died and 0.3% had transferred out. Of the 121 patients with an updated asthma classification at 24 months, the severity of their asthma had decreased: 17.4% had moderate and 0.8% had severe persistent asthma. CONCLUSION Our findings show improvements in asthma severity after 24 months and reasonable rates of loss to follow-up, demonstrating that asthma can be managed effectively in rural, resource-limited settings.

Abstract
OBJECTIVE Approximately 10% of non-small-cell lung cancer (NSCLC) remains unclassifiable as NSCLC-not otherwise specified (NOS), after using a panel of immunomarkers. The present study was undertaken to assess sensitivity and specificity of immunomarkers in sub-typing NSCLC on fine needle aspiration cytology (FNAC). Epidermal growth factor receptor (EGFR) mutations were also detected in these samples. METHODS Sixty cases of NSCLC including 15 squamous cell carcinoma (SCC), 15 adenocarcinomas (ADC) and 30 NSCLC-NOS reported on FNAC were included in the study. A panel of CK7, CK5/6, TTF-1 and p63 was applied in these cases. DNA was extracted from 54 cases including 14 effusion samples, and EGFR mutations were detected. RESULTS Classic ADC cases (n=15) showed 73.3% TTF-1 positivity and 100% CK7 positivity. Two cases of ADC showed aberrant expression of p63 and 2 cases showed CK5/6 positivity. 80% of classic SCC cases (n=15) showed strong nuclear p63 positivity and 86.6% were positive for CK5/6. TTF-1 was seen exclusively in ADC cases. Immunohistochemistry (IHC) using two immunomarkers (TTF-1 and p63) helped in subtyping 24/30(80%) cases of NSCLC. EGFR mutations were detected in 9/54 (16.7%) cases, and the most common mutation was short in-frame deletion in Exon 19. CONCLUSIONS More than 90% of NSCLC can be sub-typed on cytology samples with the help of immunochemistry. The sensitivity of TTF-1, p63, CK5/6 and CK7 was 73.3%, 80%, 100% and 100%, respectively. The specificity of TTF-1, p63, CK5/6 and CK7 was 100%, 86.6%, 86.6% and 93.3%, respectively. TTF-1 is highly specific, and almost 80% of NSCLC-NOS cases can be sub-typed using TTF-1 and p63. EGFR mutations can be detected in cytology samples, and 16.7% samples were positive for EGFR mutations.

Abstract
Background & objectives: Salmonellosis is a major public health concern worldwide. Besides typhoidal salmonellae, infections due to non-typhoidal serovars of Salmonella are also associated with high morbidity and mortality leading to huge economic losses. Among non-typhoidal serovars, Salmonella Newport has been reported as a major cause of foodborne infections resulting in outbreaks due to consumption of contaminated food items. Little data related to this serovar are available from India leading to the scarcity of information on the distribution trends of this important serovar in the country. Therefore, an effort was made in the present study to generate data on distribution trends and antibiogram of S. Newport in the country. Methods: S. Newport isolates received at the National Salmonella and Escherichia Centre at Kasauli, India, during January 2010 to December 2013 were analysed for their distribution trends and antibiogram data were also generated using standard methods. Results: In the present study, S. Newport isolates were received from eight States and one union territory of the country and highest proportion of S. Newport isolates were found to be from humans (53.61%) followed by animals (27.84%) and food (18.56%). S. Newport isolates exhibited resistance to all drugs used in the present study except chloramphenicol, ciprofloxacin and cefuroxime. Interpretation & conclusions: Considering distribution of this important serovar of Salmonalla and its wide range of reservoirs, steps towards formulation and execution of efficient surveillance programmes should be taken.

Abstract
BACKGROUND Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following: - Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy with small diameter endoscopes. - Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability. - Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour threshold, and/or one of odour identification or discrimination. - Comprehensive chemosensory assessment should include gustatory screening. - Smell training can be helpful in patients with olfactory loss of several aetiologies. CONCLUSIONS We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
BK virus (BKV) hemorrhagic cystitis (HC) is a serious cause of morbidity and mortality after allogeneic hematopoietic SCT (allo-HSCT) in patients with hematological malignancies. Around half of allogenic HSCT patients present with BKV viruria at some point after HSCT; about 5-40% of these patients subsequently develop active HC. Supportive care including bladder irrigation, blood transfusions and symptomatic pain management remains the mainstay of therapy; the acyclic nucleoside analogue cidofovir is currently the front-line drug for BKV-HC treatment. Here we report the first case of severe hemorrhagic cystitis from India who was successfully treated with low dose cidofovir therapy.
