Solid Organ Transplantation From SARS-CoV-2-infected Donors to Uninfected Recipients: A Single-center Experience. Transplant Direct 2022; 8:e1286. [PMID: 35047665 PMCID: PMC8759616 DOI: 10.1097/txd.0000000000001286] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 12/08/2021] [Accepted: 12/10/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The risk of donor-derived severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in solid organ (heart, lung, liver, kidney, pancreas, and intestine) transplant recipients is poorly understood. Since hematogenous transmission of SARS-CoV-2 has not been documented to date, nonlung solid organs might be suitable for transplantation since they likely portend a low risk of viral transmission. METHODS Abdominal solid organs from SARS-CoV-2-infected donors were transplanted into uninfected recipients. RESULTS Between April 18, 2021, and October 30, 2021, we performed transplants of 2 livers, 1 simultaneous liver and kidney, 1 kidney, and 1 simultaneous kidney and pancreas from SARS-CoV-2-infected donors into 5 uninfected recipients. None of the recipients developed SARS-CoV-2 infection or coronavirus disease 2019, and when tested, allograft biopsies showed no evidence of SARS-CoV-2 RNA. CONCLUSIONS Transplanting nonlung organs from SARS-CoV-2-infected donors into uninfected recipients demonstrated no evidence of virus transmission.

Abstract
Abstract
Introduction/Objective
T-lymphoblastic leukemia/lymphoma (T-ALL/LBL) is a malignancy arising from immature precursor T cells with T-ALL involving bone marrow/blood and T-LBL occurring in the thymus and nodal/extranodal sites. Studies have now revealed >100 recurrently altered genes that are not necessarily disease initiating but can provide diagnostic, prognostic, and predictive information which can then be utilized in personalized therapy.
Methods/Case Report
Next-generation sequencing was performed on DNA and/or RNA extracted from blood/marrow aspirates or tissue at an external CLIA-certified, CAP-accredited laboratory. The hematology panel sequenced DNA of 406 genes, introns of 31 gene rearrangements, and RNA of 265 genes.
This retrospective single-center study highlights salient findings noted in genomic profiles of 15 T-ALL/LBL cases out of 83 total patients with ALL from 2018-2021. While the majority were B-ALL cases, T-ALL accounted for 18%, and all but 1 case were pediatric patients (ages 9-21 years).
Results (if a Case Study enter NA)
In our pediatric cohort (14 patients; 9 males, 5 females), as in literature, NOTCH signaling was most frequently involved with NOTCH1 (50%) and FBXW7 (36%) mutations, followed by those in cell cycle process CDKN2A/2B (36%) and PTEN (28%) mutations. Other mutations: PHF6 (21%), BCOR and TAL1 (14%) each. The prognostic effect of mutations: NOTCH1 favorable, FBXW7 no effect but trend toward favorable when FBXW7 co-occurs with NOTCH1 while PTEN is unfavorable (3 patients had relapses). Some unusual or useful findings: a patient diagnosed initially as AML with aberrant CD3 was re-classified as early T-cell precursor ALL, supported by RELN mutation (occurs in 4% ETP-ALL). The adult with NOTCH1 and BCOR mutations in addition to BCR-ABL1 fusion was diagnosed as having T-ALL blasts with CML. We could not study detailed nuances in mutational profiles of T-ALL vs T-LBL with only 1 case of T-LBL showing FBXW7, PTEN, NF1, RB1, BCOR and NRAS mutations (latter is typically noted in pediatric T-LBL cases).
Conclusion
Clinical molecular testing in our pediatric T-ALL patients revealed gene alterations that provide refinement of diagnosis, prognosis, and risk stratification. It also contributes a useful data set for further analysis and potential use of clinically actionable therapeutic targets in some cases. Longer term follow-up incorporating therapy and outcomes information would be valuable.

Abstract
Abstract
Introduction/Objective
Recent studies continue to demonstrate that NTRK fusions occur more frequently in pediatric than in adult patients involving a broader panel of fusion partners as well as a wider range of pediatric tumors than previously recognized. The identification of these NTRK fusions has facilitated precision cancer diagnosis and TRK inhibitor targeted therapy. With the recent FDA approval of larotrectinib and entrectinib for the treatment of adult and pediatric NTRK-positive, unresectable solid tumors, identification of these fusions directly impacts patient care.
Methods/Case Report
Our patient, a 10 year old female presented with a large right sided buttock mass and pressure effects from the tumor. An incisional biopsy showed a moderately moderately cellular tumor with a collagenous and partially myxoid stroma. The atypical cells had ovoid nuclei with vesicular chromatin, minimal to no atypia, and rare mitotic activity (<2/30 high-power fields), as well as fibrous tissue that appeared as ropy collagen. Some of the blood vessels were rimmed by a hyalinized cuff. A mild inflammatory component, namely scattered lymphocytes and fewer plasma cells were noted. Immunohistochemistry showed: SMA(faint+), S100(+), CD34(+), CD31(+), FLI1(+), NTRK(+). Negative for ALK1, desmin, SOX10, EMA, keratin AE1/3, CAM5.2, D2-40, myogenin, MUC4, TLE1, STAT6, BCOR, ERG. Both INI1 and H3K27me3 were retained. Proliferative rate by Ki-67 was low, showing <2% positivity.
Next generation sequencing revealed the following: LMNA-NTRK1 fusion; CD36 N53fs*24 and CDKN2A/B CDKN2A loss exon 1. Thus, the histologic, immunophenotypic, and molecular findings together supported a diagnosis of NTRK-rearranged spindle cell tumor. This entity has alternately been termed lipofibromatosis-like tumor. Following confirmation of NTRK fusion, she was treated with oral TRK inhibitor with near total response. With this NTRK-rearranged spindle cell tumor’s minimal mitotic activity, absence of necrosis, and low cellularity, the behavior of this tumor was expected to be indolent rather than aggressive. However, the patient was presented for assessment and management at a recent tumor board about 8 months after her initial diagnosis as she had residual/recurrent tumor.
Results (if a Case Study enter NA)
NA
Conclusion
Our case highlights the clinical utility of screening for NTRK fusions in all pediatric tumors.

Abstract
The demand of electricity has been reduced significantly due to the recent COVID-19 pandemic. Governments around the world were compelled to reduce the business activity in response to minimize the threat of coronavirus. This on-going situation due to COVID-19 has changed the lifestyle globally as people are mostly staying home and working from home if possible. Hence, there is a significant increase in residential load demand while there is a substantial decrease in commercial and industrial loads. This devastating situation creates new challenges in the technical and financial activities of the power sector and hence most of the utilities around the world initiated a disaster management plan to tackle this ongoing challenges/threats. Therefore, this study aims to investigate the global scenarios of power systems during COVID-19 along with the socio-economic and technical issues faced by the utilities. Then, this study further scrutinized the Indian power system as a case study and explored scenarios, issues and challenges currently being faced to manage the consumer load demand, including the actions taken by the utilities/power sector for the smooth operation of the power system. Finally, a set of recommendations are presented to support the government/policymakers/utilities around the world not only to overcome the current crisis but also to overcome future unforeseeable pandemic alike scenario.

Utility of Discordant Mismatch Repair-Deficiency (MMR)/Microsatellite Instability (MSI) Testing in Screening Uterine Leiomyosarcoma Patient for Lynch/Other Familial Cancer Syndromes.

Abstract
Abstract
Casestudy
Lynch Syndrome (LS) is primarily linked to colorectal and endometrial cancers. Occasional sarcomas, including leiomyosarcoma, have been recognized within the spectrum of LS demonstrating mismatch repair-deficiency (MMR)/microsatellite instability (MSI) in this context.
Results
A 67-year-old female of bilineal Ashkenazi Jewish descent was recently diagnosed with uterine leiomyosarcoma in addition to metastatic papillary thyroid carcinoma at age 58. She met NCCN criteria for LS and BRCA1/2 (brother with renal cancer at age 64, father with colon cancer at age 60, paternal half-sister with rectal cancer at age 50 and maternal aunt with breast cancer).
Studies have shown that immunohistochemistry (IHC) for MMR proteins and PCR-based MSI have comparable sensitivity and specificity with high concordance, but neither test alone is sufficient to capture all defective MMR tumors. Screening strategies vary depending on the level of clinical suspicion for LS. When high, a normal result by one method warrants testing via a second method or concurrent IHC plus PCR testing to minimize the impact of rare false normal results. Rarely, this strategy can yield discordant results, as in our case wherein MSI by PCR was stable (MSS) but IHC for MLH-1 and PMS-2 showed heterogeneous (patchy/focal) nuclear loss of protein expression. The latter is not always due to artefact but can correspond to MMR status differences within the tumor, requiring recognition to prevent false-positive/false-negative evaluations. Heterogenous MLH1 and/or PMS2 expression, may be suggestive of variable MLH1 methylation/second hit mutations, variable epitope expression or expression related to variable differentiation.
Conclusion
The clinical significance of this pattern was unclear in our patient whose initial genetic screen (including MLH1, PMS2, MSH2, MSH6, EPCAM) was negative. However, as studies have indicated that patients with indeterminate IHC findings can have MLH1 hypermethylation or germline mutations, she had justification to undergo extended genetic screening. A heterozygous pathogenic variant in BLM 2207_2212delinsTAGATTC (p.Tyr736Leufs*5) associated with autosomal recessive Bloom Syndrome (BS) was identified. Carriers of BS do not show symptoms of the disease, but they are at a greater than average risk of developing cancers.

Abstract
Abstract
Casestudy
Anaplastic large cell lymphoma (ALCL), is a T-cell lymphoma typically consisting of large lymphoid cells including characteristic horseshoe- shaped hallmark cells. The rare small cell morphological variant of ALCL may pose a challenge in diagnosis, especially when the initial presentation is unusual.
Results
Our patient, a 7-year-old girl presented with a headache. A complete blood count showed leukocytosis and anemia. The smear was reported to have segmented neutrophils, reactive lymphocytes, and monocytes. A spinal tap was performed and flow analysis identified a minute aberrant T cell population (0.3% of total), positive for CD3, CD4, bright CD7; negative CD5, CD8 in the CSF sample. The peripheral blood sample was reviewed again; some small- medium atypical lymphocytes, with irregular nuclear contours and cytoplasmic azurophilic granules were noted. Flow immunophenotyping displayed an aberrant T cell population positive for CD45, CD2, CD3, bright CD7, CD4, CD13; negative CD30, TdT CD5, CD8, CD117, CD34; consistent with T cell lymphoma/leukemia. A cell block prepared from peripheral blood sample showed blood with numerous atypical cells with irregular nuclei positive for ALK, CD30, CD3, CD4, CD7; negative CD5 and CD8. A diagnosis of leukemic ALK(+) ALCL was rendered, though classic hallmark cells were difficult to see. A marrow biopsy showed interstitial and sinusoidal pattern of mainly small to medium-sized cells with irregular nuclei. Molecular study revealed ALK gene alteration showing characteristic NPM1-ALK fusion. The patient underwent a bone bone marrow transplantation but recently relapsed with a submandibular lymph hode biopsy showing the presence of many larger ALCL cells.
Conclusion
Correct clinical diagnosis of the small-cell variant of ALCL is often challenging as the scarce “hallmark cells” are scattered and difficult to recognize. While leukemic peripheral blood involvement is rare in ALCL, an association has been reported with small-cell variants, which may be a potential explanation for the poor prognosis and aggressive nature of small-cell variant ALCL. A meticulous examination of peripheral blood smears, comprehensive immunophenotypic studies, and early bone marrow and lymph node/tissue biopsy are needed to facilitate diagnosis.

Modelling photovoltaic soiling losses through optical characterization. Sci Rep 2020; 10:58.

Abstract
The accumulation of soiling on photovoltaic (PV) modules affects PV systems worldwide. Soiling consists of mineral dust, soot particles, aerosols, pollen, fungi and/or other contaminants that deposit on the surface of PV modules. Soiling absorbs, scatters, and reflects a fraction of the incoming sunlight, reducing the intensity that reaches the active part of the solar cell. Here, we report on the comparison of naturally accumulated soiling on coupons of PV glass soiled at seven locations worldwide. The spectral hemispherical transmittance was measured. It was found that natural soiling disproportionately impacts the blue and ultraviolet (UV) portions of the spectrum compared to the visible and infrared (IR). Also, the general shape of the transmittance spectra was similar at all the studied sites and could adequately be described by a modified form of the Ångström turbidity equation. In addition, the distribution of particles sizes was found to follow the IEST-STD-CC 1246E cleanliness standard. The fractional coverage of the glass surface by particles could be determined directly or indirectly and, as expected, has a linear correlation with the transmittance. It thus becomes feasible to estimate the optical consequences of the soiling of PV modules from the particle size distribution and the cleanliness value.

Abstract
Abstract
Background
Hypertension is the most common cause of the rising cardiovascular disease (CVD) epidemic in India. However, despite availability of proven therapies management remains sub-optimal.
Purpose
To determine the hypertension control rates and associated factors among adults with known hypertension in urban and rural India.
Methods
We conducted a representative population based cross-sectional survey among 12243 participants aged ≥30 years residing in rural and urban North and South India. Participants were selected using a multistage cluster random sampling technique. Trained personnel collected the data using an interviewer administered questionnaire, measured blood pressure, conducted anthropometry and collected bio-samples. Hypertension was defined as known hypertension (self-report of physician diagnosis) or systolic blood pressure (SBP) ≥140 mmHg or diastolic blood pressure (DBP) ≥90 mmHg. Control was defined as SBP <140 mmHg and DBP <90 mmHg among those with known hypertension. The associations were measured using logistic regression.
Results
The mean (±SD) age of participants was 47.7 (±12.5) years, women comprised 54%. The age-standardized prevalence of hypertension was 29.0% (95% CI: 28.2- 29.8) and known hypertension was 14.0% (13.4- 14.6). Among all hypertensives 38.6% (37.0–40.2) were on treatment and 26.2% (24.6–28.0) had their blood pressure controlled, while among known hypertensives 79.8% (77.8–81.7) were on treatment and 55.7% (53.3–58.1) had their blood pressure controlled. In multivariate analysis, participants from North Indian site [OR: 1.9 (1.6–2.3)], urban residents [1.3 (1.1–1.6)], younger participants [1.5 (1.2–1.8)], men [2.0 (1.5–2.6)], those with low socio-economic status [1.6 (1.1–2.3)], without comorbidities and those without a family history hypertension were more likely to be unaware about their hypertensive status and less likely to take treatment. Hypertension control was significantly higher in participants from South Indian site [1.5 (1.2–1.0)], the highly educated [1.6 (1.1–2.4)], those without heart diseases [1.8 (1.1–3.1)], those without central obesity [1.4 (1.1–1.9)], physically active individuals [1.5 (1.1–2.0)] and current non-alcohol users [1.9 (1.3–2.6)].
Conclusions
Many individuals with hypertension remain unaware and sub-optimally managed. This warrants the implementation of tailored public education to raise awareness, complemented by active screening for the early detection and effective management of hypertension, in order to stem the rising tide of preventable CVD in India.

Abstract
Objective Trans-fat, an invariable component of industrial fat is considered as one of the major dietary factors associated with CVD. Although the use of trans-fat is completely banned in some of the high-income countries where the CVD epidemic is declining, it is widely used in LMIC. We aimed to investigate the association of trans fatty acid in serum with risk markers of CVD in an industrial population in India. Participants were randomly selected from a study conducted in an industrial setting among employees and their family members. Information related to their demographic profile, anthropometric measurements, oil intake were recorded. Fasting samples were collected and stored at − 80 °C for analysis. Their lipid profile and hs CRP were measured and fatty acids analyzed using gas chromatography (GC) with flame ionization detector (FID). Results Complete data was available for 176 participants. Among trans fatty acids, mono trans fatty acid was significant predictor of serum triglycerides [Unadjusted β (95% CI) 22.9 (2.6, 43.2); Adjusted β (95% CI) 20.4 (3.5, 37.3)]. None of the other trans fatty acids either individually or in group correlated with any of the biochemical markers studied.

Abstract
Waitlist time for kidney transplantation is long but may be shortened with the utilization of hepatitis C positive allografts. We retrospectively reviewed the course of 36 hepatitis C positive patients awaiting kidney transplantation at 2 large centers within the same health system, with near-identical care delivery models with the exception of timing of hepatitis C treatment, to determine the impact of timing of hepatitis C treatment on access to transplant, waitlist time, and treatment efficacy and tolerability. The majority of patients had hepatitis C genotype 1a or 1b, and all received direct acting antiviral therapy with 100% treatment response. One patient underwent transplantation in the pretransplant treatment group. The 1-year transplantation rate was 12.5% vs 67.9% (P = .0013) in those treated posttransplantation. The median waitlist time in the posttransplant group was 122 (interquartile range [IQR] 21.5, 531.0) days, which was significantly shorter than the center's regional and national wait time. Pathologic review revealed no difference in allograft quality. Overall treatment related adverse events were not different between the 2 groups. A strategy of posttransplant hepatitis C treatment increased access to transplant and reduced waitlist time. Delaying treatment until after transplant did not appear to adversely affect recipients' kidney allograft or overall survival.

Increasing the Use of Kidneys From Unconventional and High-Risk Deceased Donors. Am J Transplant 2016; 16:3086-3092.

Abstract
In this paper, we have reviewed the literature and report on kidney donors that are currently used at relatively low rates. Kidneys from donors with acute kidney injury (AKI) seem to have outcomes equivalent to those from donors without AKI, provided one can rule out significant cortical necrosis. Kidneys from donors with preexisting diabetes or hypertension may have marginally lower aggregate survival but still provide patients with a significant benefit over remaining on the wait list. The Kidney Donor Profile Index derives only an aggregate association with survival with a very modest C statistic; therefore, the data indicated that this index should not be the sole reason to discard a kidney, except perhaps in patients with extremely low estimated posttransplant survival scores. It is important to note that the Scientific Registry of Transplant Recipients models of risk adjustment should allay concerns regarding regulatory issues for observed outcomes falling below expectations. The successful utilization of kidneys from donation after cardiac death over the past decade shows how expanding our thinking can translate into more patients benefiting from transplantation. Given the growing number of patients on the wait list, broadening our approach to kidney acceptance could have an important impact on the population with end-stage renal disease. Many lives could be prolonged by carefully considering use of kidneys that are often discarded.

Abstract
OBJECTIVE To assess the change in the quality of life (QOL) in Oropharyngeal, Laryngeal and Hypopharyngeal cancer patients treated with concomitant boost radiotherapy by Volumetric Intensity Modulated Arc Therapy (VMAT) technique. METHODS Thirty patients with oropharynx, larynx or hypopharynx cancers of stage II to IVA were treated with an Accelerated fractionation schedule using Concomitant boost. The dose given was 1.8Gy/fraction daily, 5 days a week to the large field for 28 fractions and a daily concomitant boost of 1.5Gy/fraction to the boost field over the last 12 treatment days for a total dose of 68.4Gy/40 fractions/5½weeks by VMAT technique with concurrent chemotherapy (in stage III and IV patients) using Cisplatin 100mg/m2 IV three weekly during week 1 and week 4 of irradiation. QOL was assessed using the European Organization of Research and Treatment of Cancer Quality of Life Core Questionnaire, version 3.0 (EORTC QLQC30) and EORTC head and neck module (EORTC QLQ-HN35) before treatment, at the end of treatment, 1 month, 3 months and 6 months post treatment. The QOL scores and their evolution over the five measurements were calculated. RESULTS The change in the QOL scores was acceptable in general. There was a significant reduction in quality of life scores at the end of treatment. The QOL improved in the followup period; and by 3 months post irradiation, there was a return of QOL scores to the baseline value. CONCLUSION The QOL scores indicate that concomitant boost radiotherapy by VMAT is well tolerated and helps in rapid return to baseline quality of life scores. We believe that this is one of the first papers which have combined concomitant boost radiotherapy with VMAT technique in head and neck cancers. VMAT based concomitant boost radiotherapy helps in rapid return to baseline quality of life.

Rapid Resolution of Donor-Derived Glomerular Fibrin Thrombi After Deceased Donor Kidney Transplantation. Am J Transplant 2016; 16:1015-20. [PMID: 26689853 DOI: 10.1111/ajt.13561] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2015] [Revised: 09/11/2015] [Accepted: 09/29/2015] [Indexed: 01/25/2023]
Abstract
The aim of this study was to determine the clinical and histologic outcomes related to transplanting kidneys from deceased donors with glomerular fibrin thrombi (GFT). We included all cases transplanted between October 2003 and October 2014 that had either a preimplantation biopsy or an immediate postreperfusion biopsy showing GFT. The study cohort included 61 recipients (9.9%) with GFT and 557 in the control group without GFT. Delayed graft function occurred in 49% of the GFT group and 39% in the control group (p = 0.14). Serum creatinine at 1, 4, and 12 months and estimated GFR at 12 months were similar in the two groups. Estimated 1-year graft survival was 93.2% in the GFT group and 95.1% in the control group (p = 0.22 by log-rank). Fifty-two of the 61 patients in the GFT group (85%) had a 1-month protocol biopsy, and only two biopsies (4%) showed residual focal glomerular thrombi. At the 1-year protocol biopsy, the prevalence of moderate to severe interstitial fibrosis and tubular atrophy was 24% in the GFT group and 30% in the control group (p = 0.42). We concluded that GFT resolves rapidly after transplantation and that transplanting selected kidneys from deceased donors with GFT is a safe practice.

Abstract
Our aim was to determine outcomes with transplanting kidneys from deceased donors with acute kidney injury, defined as a donor with terminal serum creatinine ≥2.0 mg/dL, or a donor requiring acute renal replacement therapy. We included all patients who received deceased donor kidney transplant from June 2004 to October 2013. There were 162 AKI donor transplant recipients (21% of deceased donor transplants): 139 in the standard criteria donor (SCD) and 23 in the expanded criteria donor (ECD) cohort. 71% of the AKI donors had stage 3 (severe AKI), based on acute kidney injury network (AKIN) staging. Protocol biopsies were done at 1, 4, and 12 months posttransplant. One and four month formalin-fixed paraffin embedded (FFPE) biopsies from 48 patients (24 AKI donors, 24 non-AKI) underwent global gene expression profiling using DNA microarrays (96 arrays). DGF was more common in the AKI group but eGFR, graft survival at 1 year and proportion with IF/TA>2 at 1 year were similar for the two groups. At 1 month, there were 898 differentially expressed genes in the AKI group (p-value <0.005; FDR <10%), but by 4 months there were no differences. Transplanting selected kidneys from deceased donors with AKI is safe and has excellent outcomes.

Abstract
The recent Ebola crisis has re-opened the debate on global health governance and the role of the World Health Organization. In order to analyze what is at stake, we apply two conceptual approaches from the social sciences - the work on gridlock and the concept of cosmopolitan moments - to assess the ability of the multilateral governance system to reform. We find that gridlock can be broken open by a health crisis which in turn generates a political drive for change. We show that a set of cosmopolitan moments have led to the introduction of the imperative of health in a range of policy arenas and moved health into 'high politics' - this has been called a political revolution. We contend that this revolution has entered a second phase with increasing interest of heads of state in global health issues. Here lies the window of opportunity to reform global health governance.

Abstract
The present study was undertaken to evaluate the efficacy of radiotherapy in palliation of dysphagia in patients with squamous cell carcinoma (SCC) of esophagus and to see the quality of life (QoL) following radiotherapy. This was a prospective clinical study done between September 2006 and May 2008. All consecutive patients with SCC of the esophagus, who are not candidates for definitive treatment, were included in the study. Dysphagia and QoL were assessed using modified Takita's grading and modified questionnaire based on EORTC QLQ 30 respectively. External beam radiotherapy (EBRT) was delivered to all patients using linear accelerator 6 Mv photons. Patients who had good response with EBRT were further subjected to intraluminal brachytherapy (ILBT) at 700 cGy using Iridium-192. The cumulative dose each patient received was 65 Gy. Patients were followed up at 6 weeks from completion of treatment to look for any difference in dysphagia grade and QoL following therapy. Thirty-three patients were included in the study. The mean age among males and females was 60.9 and 49.8 years, respectively. Nineteen patients (57.6 %) received EBRT followed by ILBT; the remaining patients received only EBRT. Seven were lost during follow-up, and seven (21.2 %) died during the study period of 6 weeks. Nineteen (57.6 %) were followed up. On follow-up endoscopy, evidence of residual stricture was observed in 57.9 %, and growth in 36.8 %. Of the patients, 27.8 % had biopsy-confirmed residual disease. The median dysphagia score decreased from 4 to 3 after treatment (p = 0.002) in 17 (89.5 %) patients. The mean QoL score improved from 107.5 to 114.1 at 6-week follow-up. Following radiotherapy, 26.3 % had persistent chest pain, increased cough with expectoration in 15.8 %, and hyperpigmentation of skin in 10.5 %. Radiotherapy gives significant relief of dysphagia and improves QoL in 90 % of patients with SCC of esophagus. However, following radiotherapy, a number of patients will have persistent stricture, ulceration, and residual disease.

Abstract
The effectiveness and short-term safety of recombinant human GH (r-hGH) in acromegaly patients with GH deficiency (GHD) after treatment are not well established. The study includes ten subjects with acromegaly who had GHD treated with r-hGH for 6 months. Control groups consisted of ten age-, gender-, and BMI-matched healthy subjects and ten active acromegaly patients who were treatment naïve. Body composition, quality of life (QoL), muscle strength, lipid profile, and cardiovascular risk factors were assessed in all subjects at baseline, and the same parameters were reassessed after 6 months of therapy with r-hGH in acromegaly with GHD. Repeat magnetic resonance imaging of the sella was performed in treated subjects. Optical colonoscopy was done and biopsies were taken from multiple sites for proliferation indices (Ki67). The median duration of GHD was 17.8 months and dose of r-hGH administered was 5.7±1.5 μg/kg per day. There was improvement in bone mineral content (P=0.01), bone mineral density (P=0.04), muscle strength (P<0.001), total cholesterol (P=0.003), high-density cholesterol (P<0.001), and QoL - score (P=0.005), and reduction in low-density cholesterol (P=0.003) and triglyceride (P=0.004) after treatment. There was no change in lean body mass, total body fat, hsCRP, lipoprotein (a), and fibrinogen levels. There was a modest increase in plasminogen activator inhibitor 1 (P=0.002), but it was lower compared with healthy controls and treatment naïve acromegalics (P=0.007). Six month-r-hGH therapy improves body composition, atherogenic lipid profile, QoL, and muscle strength in GHD patients who had acromegaly. Long-term prospective studies are needed to evaluate the effect of r-hGH therapy in these patients.

Abstract
Olfactory neuroblastomas make up about 3-5% of malignant intra-nasal tumors and originate from the olfactory neuroepithelium lining the roof of the nasal vault. There exist no optimum treatment guidelines from randomized data due to paucity of patients. Treatment options range from minimal surgery to extensive cranio-facial resections and adjuvant radiotherapy. In this case a tumor engulfing optic nerve and globe was safely treated by 3D-CRT with complete remission and relative sparing of the eye as well as late toxicities were avoided. 3D-CRT permits increased dose to tumor sparing critical areas and is a feasible option in centres without IMRT.

Abstract
BACKGROUND AND OBJECTIVES Pre-operative chemoradiation (preop CRT) plus intraoperative electron irradiation (IOERT) has been used in the multidisciplinary treatment for patients with locally advanced unresectable or borderline resectable pancreas cancer. This review was performed to evaluate survival, relapse patterns and prognostic factors in patients treated with curative intent. METHODS Between January 2002 and December 2010, 48 patients with locally advanced pancreatic ductal adenocarcinoma received preop CRT prior to an attempt at resection and IOERT. 31/48 (65%) patients proceeded to curative-intent surgical resection. Resection status prior to preop CRT was locally unresectable (20 patients) and borderline resectable (11 patients). Preop CRT (45-50.4 Gy/25-28 Fx in 27/31) was delivered with concurrent 5FU or gemcitabine-based regimens. Subsequent gross total resection was achieved in 16 patients (R0, 11; R1, 5). IOERT was delivered in 28 patients (dose, 10-20 Gy). 16 patients also received adjuvant post-operative systemic chemotherapy. Outcomes evaluated include survival, local failure in the EBRT field (LF), central failure in the IOERT field (CF), and distant metastases. RESULTS Resection status was predictive for survival and for patterns of relapse. For patients with at least a gross total resection after preop CRT (R0/R1; n=16) vs. no resection (n=15), both median and overall survival were improved (median 23 vs. 10 months; 2-year, 40% vs. 17%; 3-year, 40% vs. 0%; P=0.002). Liver or peritoneal relapse was documented in 22/31 patients (71%); LF/CF in 5/26 (16%). CONCLUSIONS Long term survival and disease control are achievable in select patients with borderline resectable or locally unresectable pancreas cancer when gross total surgical resection is achieved after preop CRT. Continued evaluation of curative-intent combined modality therapy is warranted in this high risk population, but additional strategies are needed to improve resectability and disease control.

Abstract
India is experiencing multiple transitions with respect to nutrition patterns, epidemiology and demography. Along with staggering childhood undernutrition, a rapid rise in chronic diseases and their risk factors including overweight-obesity (O-O), among all sections of society, is compounding India's health challenges. We present an overview of the O-O scenario (prevalence, determinants) and profile existing initiatives to address this modifiable risk factor in India. Urgent attention from all sectors, committed resources, policy support and targeted actions are warranted to combat the dual burden of malnutrition. The health systems should be reoriented and strengthened, in addition to enabling actions in other sectors, to address prevention and control of non-communicable diseases and associated risk factors like O-O.

Abstract
This study assessed perceptions and support among the Indian populace about plain packaging for all tobacco products. Twelve focus group discussions (n = 124), stakeholder analysis with 24 officials and an opinion poll with 346 participants were conducted between December 2011 and May 2012, Delhi. Plain packages for tobacco products were favored by majority of participants (69%) and key stakeholders (92%). The majority of participants perceived that plain packaging would reduce the appeal and promotional value of the tobacco pack (>80%), prevent initiation of tobacco use among children and youth (>60%), motivate tobacco users to quit (>80%), increase notice ability, and effectiveness of pictorial health warnings on tobacco packs (>90%), reduce tobacco usage (75% of key stakeholders). Majority of participants favored light gray color for plain packaging. This study provides key evidence to advocate with Indian Government and other countries in South Asia region to introduce plain packaging legislation for all tobacco products.

Abstract
Tacrolimus pharmacokinetics vary due to single nucleotide polymorphisms (SNPs) in metabolizing enzymes and membrane transporters that alter drug elimination. Clinically we observed that Native Americans require lower dosages of tacrolimus to attain trough levels similar to Caucasians. We previously demonstrated that Native Americans have decreased oral clearance of tacrolimus, suggesting that Native Americans may have more variant SNPs and, therefore, altered tacrolimus pharmacokinetic parameters. We conducted 12-hour pharmacokinetic studies on 24 adult Native American kidney transplant recipients on stable doses of tacrolimus for at least 1 month posttransplantation. Twenty-four Caucasian kidney transplant recipients were compared as controls. SNPs encoding the genes for the enzymes (CYP3A4, CYP3A5) and transporters (ABCB1, BCRP, and MRP1) were typed using TaqMan. The mean daily tacrolimus dose in the Native Americans was 0.03 ± 0.02 compared with the Caucasians 0.5 ± 0.3 (mg/kg/d; P = .002), with no significant differences in trough levels, (6.7 ± 3.1 vs 7.4 ± 2.1 ng/dL; P = .4). Many Native Americans, but not Caucasians, demonstrated the 3/*3 - C3435T CC and the *3/*3 -G2677T GG genotype combination previously associated with low tacrolimus dosing. Native Americans required significantly lower tacrolimus doses than Caucasians to achieve similar tacrolimus trough levels, in part due to lower tacrolimus clearance from decreased drug metabolism and excretion.

Abstract
UNLABELLED Growth in early life may predict adult bone health. Our data showed that greater height and body mass index (BMI) gain in utero and infancy are associated with higher peak bone mass, and greater BMI gain in childhood/adolescence with higher peak bone density. These associations are mediated by attained adult height and BMI. INTRODUCTION To study the relationship of height and BMI during childhood with adult bone mineral content (BMC), areal density (aBMD) and apparent density (BMAD, estimated volumetric density). METHODS Participants comprised 565 men and women aged 33-39 years from the New Delhi Birth Cohort, India, whose weight and height were recorded at birth and annually during infancy (0-2 years), childhood (2-11 years) and adolescence (11 years-adult). Lumbar spine, femoral neck and forearm BMC and aBMD were measured using dual X-ray absorptiometry; lumbar spine and femoral neck BMAD were calculated. RESULTS Birth length, and height and height gain during infancy, childhood and adolescence were positively correlated with adult BMC (p≤0.01 all sites except birth length with femoral neck). Correlations increased with height from birth to 6 years, then remained constant for later height measurements. There were no associations with BMAD. BMI at birth, and during childhood and adolescence was also positively correlated with BMC (p < 0.01 all sites). BMI at 11 years, and BMI gain in childhood and adolescence, were correlated with aBMD and BMAD (p < 0.001 for all); these correlations strengthened with increasing age of BMI measurement. The associations with height and BMI in early life became non-significant after adjustment for adult height and BMI. CONCLUSIONS Greater skeletal growth and BMI gain in utero and during infancy are associated with higher peak BMC, and greater BMI gain in childhood and adolescence is associated with higher peak aBMD and BMAD. These associations are mediated by the attainment of adult height and BMI, respectively.

Abstract
AIM Chronic radiation proctitis with bleeding is a common problem encountered following radiotherapy for pelvic malignancy. Sucralfate-steroid enema and formalin dab are two common nonsurgical treatments. A randomized trial was conducted to compare the efficacy of these two methods. METHOD This was a prospective randomized controlled trial conducted in the Jawaharlal Institute of Postgraduate Medical Education & Research (JIPMER) from August 2005 to May 2007. One-hundred and two patients with chronic radiation proctitis, presenting as rectal bleeding after radiotherapy for carcinoma of the cervix, were recruited and randomly allocated into two treatment groups: Group 1, formalin dab; and Group 2, sucralfate-steroid retention enema. The mean age of the patients was 51.3 ± 5.1 years. The mean interval between the end of radiotherapy and the onset of bleeding was 12.3 ± 3.5 months. Symptom score and sigmoidoscopic grade were assessed before, and at 1 month after, treatment. RESULTS Ninety per cent of patients in Group 1 and 74.5% of patients in Group 2 responded to treatment (P = 0.038). In spite of having a higher median symptom score before treatment, patients in Group 1 demonstrated a marked decrease in symptom score after treatment compared with patients in Group 2 and the difference once again was statistically significant (P = 0.000). Similarly, the median sigmoidoscopic grade was significantly lower for patients in Group 1 compared with patients in Group 2 after treatment (P = 0.000). There were no specific treatment-related complications in either group. CONCLUSIONS Formalin (4%) dab is superior to sucralfate-steroid retention enema for treatment of chronic haemorrhagic radiation proctitis.

Abstract
Background & objectives: Adherence to ART is a patient specific issue influenced by a variety of situations that a patient may encounter, especially in resource-limited settings. A study was conducted to understand factors and influencers of adherence to ART and their follow ups among patients attending ART centres in Maharashtra, India. Methods: Between January and March 2009, barriers to ART adherence among 32 patients at three selected ART centres functioning under national ART roll-out programme in Maharashtra, India, were studied using qualitative methods. Consenting patients were interviewed to assess barriers to ART adherence. Constant comparison method was used to identify grounded codes. Results: Patients reported multiple barriers to ART adherence and follow up as (i) Financial barriers where the contributing factors were unemployment, economic dependency, and debt, (ii) social norm of attending family rituals, and fulfilling social obligations emerged as socio-cultural barriers, (iii) patients’ belief, attitude and behaviour towards medication and self-perceived stigma were the reasons for sub-optimal adherence, and (iv) long waiting period, doctor-patient relationship and less time devoted in counselling at the center contributed to missed visits. Interpretation & conclusions: Mainstreaming ART can facilitate access and address ‘missed doses’ due to travel and migration. A ‘morning’ and ‘evening’ ART centre/s hours may reduce work absenteeism and help in time management. Proactive ‘adherence probing’ and probing on internalized stigma might optimize adherence. Adherence probing to prevent transitioning to suboptimal adherence among patients stable on ART is recommended.

Adverse drug reaction profile of cisplatin-based chemotherapy regimen in a tertiary care hospital in India: An evaluative study. Indian J Pharmacol 2011; 42:40-3. [PMID: 20606836 PMCID: PMC2885639 DOI: 10.4103/0253-7613.62412] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2009] [Revised: 10/12/2009] [Accepted: 03/12/2010] [Indexed: 11/22/2022] Open
Abstract
Aims: This prospective study was designed to monitor and analyze the pattern of occurrence of adverse drug reactions (ADRs) to cisplatin-based chemotherapy regimen in the cancer ward of a tertiary care hospital. Materials and Methods: Cancer patients who received cisplatin-based cancer chemotherapy were monitored for adverse reactions. The collected reports were analyzed for demographic and drug details, causality, preventability and severity of adverse effects. Causality was assessed by the World Health Organization (WHO) causality assessment scale and Naranjo's Algorithm. Preventability and severity of ADRs were assessed by modified Schumock and Thornton scale, modified Hartwig and Siegel scale respectively. Results: Among 51 patients, 48 developed ADRs to cisplatin chemotherapy. The reactions observed were nausea, alopecia, anorexia, vomiting, taste alteration, diarrhea, constipation, tinnitus, and hypocalcaemia. The WHO causality assessment scale indicated 69% “possible” and 31% “probable” but no “certain” reactions. Naranjo's Algorithm showed 62% “probable” and 38% “possible” reactions. Most of the reactions belonged to the category of “not preventable”. Reactions like nausea and vomiting belonged to the category of “definitely preventable”. Modified Hartwig and Siegel scale of severity assessment showed that most of the reactions were of “mild level 1” severity except for vomiting, diarrhea and hypocalcaemia, which were of “moderate level 3” severity. Conclusion: Cisplatin-based chemotherapy has a high potential to cause adverse effects. Most of the reactions were of milder nature but not preventable. The common adverse effects such as nausea and vomiting were preventable, but reactions like hypersensitivity reactions and anaphylaxis were not predictable.

Abstract
A total of 225 day-old sexed male broiler chicks (Vencobb strain) were divided randomly into 15 groups consisting of 15 chicks in each group to study the toxicity of lead on hepatocytes. Group 1 was maintained on basal diet, group 2 on polyherbal formulation (PHF; stressroak), group 3 on shilajith, group 4 on amla and group 5 on vit E + Se. Group 6 was maintained on lead for 6 weeks and group 7 on lead for 4 weeks and subsequently on basal diet without lead for the remaining 2 weeks. Groups 8, 9, 10 and 11 were given lead along with PHF, shilajith, amla and vit E + Se, respectively, throughout 6 weeks. Groups 12, 13, 14 and 15 were given lead containing diet for the first 4 weeks and subsequently treated with PHF, shilajith, amla and vit E + Se, respectively, for the remaining 2 weeks. The activity of alanine transaminase (ALT) was significantly (P<0.05) increased in the toxic control groups at the end of 4(th) week as compared to group 1. However, following treatment, there was a significant (P<0.05) reversal in groups 12-15. The activity of Na(+)/K(+)-ATPase, Ca(2+)ATPase, Mg(2+)ATPase and CYP(450) was significantly (P<0.05) reduced in the liver of toxic control groups 6 and 7 as compared to groups1 through 5, which had the maximum activity of all the groups. Groups 8 through 15 revealed a significant (P<0.05) increase in the activity of these hepatocytic enzymes. The histological sections of the liver in lead toxic control (group 6) showed moderate focal lymphoid aggregates in liver, whereas the lesions were mild to moderate in treated groups and there were no observable lesions in plain control groups. The study revealed protective effect of PHF (stressroak), shilajith, amla and vit E + Se in lead-induced hepatocytic damage.

Abstract
Isolated failure of the renal graft after simultaneous kidney-pancreas transplantation (SPK) is a rare but potential outcome. Many of these patients are candidates for kidney retransplantation. This paper describes a series of 3 patients who underwent successful kidney retransplantation after SPK. The operation was completed through an extraperitoneal incision without disruption of the pancreas graft or need for a transplant nephrectomy.

Abstract
Cardiovascular diseases (CVD) are the leading cause of death and disability in both developed and developing countries. In developed countries socio-economic mortality differentials have been studied extensively showing that the low socio-economic group suffers the highest mortality. As the epidemiological transition is taking place against a background of economic globalization, CVD risk factors among the urban poor and middle class are rapidly increasing in India. Recent evidences from India also suggest reversal of social gradient with excess burden of CVD morbidity in the low socio-economic group. Understanding the social determinants of environmental and behavioural exposures, in determining the risk factors for cardiovascular disease is an important challenge for public health professionals as well as communities. Socio-economic disadvantage is not simply a proxy for poor cardiovascular risk factor status, but also an indication of the likely trajectory that an individual or a community may follow in the course of their life. The paucity of intervention research seeking to address the role of social determinants in shaping lifestyle practices among individuals in culturally and socially diverse population groups within India is definitely a measure of inadequacy in public health research. This review article provides an overview of the role of social determinants of CVD and its possible conceptual pathways with special focus on acute coronary syndrome (ACS) outcomes among Indians.

Outcomes after simultaneous pancreas and kidney transplantation and the discriminative ability of the C-peptide measurement pretransplant among type 1 and type 2 diabetes mellitus. Transplant Proc 2011; 42:2650-2. [PMID: 20832562 DOI: 10.1016/j.transproceed.2010.04.065] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2009] [Accepted: 04/20/2010] [Indexed: 12/21/2022]
Abstract
BACKGROUND Earlier studies reporting outcomes after pancreas transplantation have included a combination of C-peptide cutoffs and clinical criteria to classify type 2 diabetes mellitus (T2DM). However, because the kidney is the major site for C-peptide catabolism, C-peptide is unreliable to discriminate the type of diabetes in patients with kidney disease. METHODS To improve the discriminative power and better classify the type of diabetes, we used a composite definition to identify T2DM: presence of C-peptide, negative glutamic acid decarboxylase antibody, absence of diabetic ketoacidosis, and use of oral hypoglycemics. Additionally among T2DM patients with end-stage renal disease (ESRD), body mass index of <30 kg/m(2) and use of <1 u/kg of insulin per day were selection criteria for suitablity for simultaneous pancreas and kidney transplantation (SPKT). We compared graft and patient survival between T1DM and T2DM after SPKT. RESULTS Our study cohort consisted of 80 patients, 10 of whom were assigned as T2DM based on our study criteria. Approximately 15% of patients with T1DM had detectable C-peptide. Cox regression survival analyses found no significant differences in allograft (pancreas and kidney) or patient survival between the 2 groups. The mean creatinine clearance at 1 year estimated by the modification of Diet in Renal Disease (MDRD) equation was not significantly different between the 2 groups. Among those with 1 year of follow-up, all patients with T2DM had glycosylate hemoglobin of <6.0 at 1 year versus 92% of those with T1DM. CONCLUSION SPKT should be considered in the therapeutic armamentarium for renal replacement in selected patients with T2DM and ESRD. Use of C-peptide measurements for ESRD patients can be misleading as the sole criterion to determine the type of diabetes.

Abstract
Ampullary and proximal pancreatic duct strictures are well known to result in recurrent episodes of pancreatitis in the native pancreas, which when benign in origin can often be treated with sphincteroplasty (open or endoscopic) and stenting in the native pancreas. However, recurrent episodes of pancreatitis in a transplanted pancreas allograft can have multiple potential etiologies, and if the diagnosis of pancreatic duct stricture is made, treatment with preservation of the pancreatic allograft can be challenging. This is the first case report to describe the open sphincteroplasty of a short benign ampullary stricture in a transplant pancreas allograft.

A cross-sectional investigation of regional patterns of diet and cardio-metabolic risk in India. Nutr J 2011; 10:12.

Abstract
Background The role of diet in India's rapidly progressing chronic disease epidemic is unclear; moreover, diet may vary considerably across North-South regions. Methods The India Health Study was a multicenter study of men and women aged 35-69, who provided diet, lifestyle, and medical histories, as well as blood pressure, fasting blood, urine, and anthropometric measurements. In each region (Delhi, n = 824; Mumbai, n = 743; Trivandrum, n = 2,247), we identified two dietary patterns with factor analysis. In multiple logistic regression models adjusted for age, gender, education, income, marital status, religion, physical activity, tobacco, alcohol, and total energy intake, we investigated associations between regional dietary patterns and abdominal adiposity, hypertension, diabetes, and dyslipidemia. Results Across the regions, more than 80% of the participants met the criteria for abdominal adiposity and 10 to 28% of participants were considered diabetic. In Delhi, the "fruit and dairy" dietary pattern was positively associated with abdominal adiposity [highest versus lowest tertile, multivariate-adjusted OR and 95% CI: 2.32 (1.03-5.23); Ptrend = 0.008] and hypertension [2.20 (1.47-3.31); Ptrend < 0.0001]. In Trivandrum, the "pulses and rice" pattern was inversely related to diabetes [0.70 (0.51-0.95); Ptrend = 0.03] and the "snacks and sweets" pattern was positively associated with abdominal adiposity [2.05 (1.34-3.14); Ptrend = 0.03]. In Mumbai, the "fruit and vegetable" pattern was inversely associated with hypertension [0.63 (0.40-0.99); Ptrend = 0.05] and the "snack and meat" pattern appeared to be positively associated with abdominal adiposity. Conclusions Cardio-metabolic risk factors were highly prevalent in this population. Across all regions, we found little evidence of a Westernized diet; however, dietary patterns characterized by animal products, fried snacks, or sweets appeared to be positively associated with abdominal adiposity. Conversely, more traditional diets in the Southern regions were inversely related to diabetes and hypertension. Continued investigation of diet, as well as other environmental and biological factors, will be needed to better understand the risk profile in this population and potential means of prevention.

Measuring obesity among school-aged youth in India: a comparison of three growth references. Indian Pediatr 2010; 48:105-10. [PMID: 20972296 DOI: 10.1007/s13312-011-0041-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2009] [Accepted: 03/02/2010] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To compare three growth references that can be used to assess the weight status of school-aged youth living in India, with a particular focus on identifying overweight and obese youth. STUDY DESIGN Cross-sectional study. Kappa scores were used to measure agreement between growth references. Regression models were used to test for differences in weight status by grade level, gender, and school type, using each growth reference. SETTING Private (n=4) and Government schools (n=4) in Delhi, India. PARTICIPANTS Students (n=1818) in eighth and tenth grade attending the schools. MAIN OUTCOME MEASURES Weight status was derived using age- and gender-specific cut-points provided by: (a) a national growth reference specific to India; (b) an international reference recommended by the International Obesity Task Force (IOTF); and (c) a new international reference recommended by the World Health Organization (WHO). RESULTS The IOTF reference consistently classified participants in a lower weight status category, compared with the national reference (k=0.57) and the WHO reference (k=0.69). The agreement between the WHO and the national references was higher (k=0.84). CONCLUSIONS To date, all published studies of childhood obesity in India have used the IOTF reference, the national reference, or an old WHO reference to measure weight status among school-going youth. The new WHO reference may be a better choice. Compared to the IOTF reference, it does not appear to underestimate obesity and can still be used to compare trends, globally.

Abstract
Simultaneous pancreas-kidney transplantation (SPKT) is the treatment of choice for patients with end-stage renal failure due to type 1 diabetes mellitus. With advances in surgical techniques and immunosuppression management, outcomes have improved, with current 1- and 10-year pancreas graft survival rates of 86% and 53%, respectively. Induction therapy with either alemtuzumab or rabbit antithymocyte globulin (rATG) in combination with a calcineurin inhibitor (CNI) and mycophenolate mofetil (MMF) or sirolimus appears to be safe and effective in the setting of rapid steroid withdrawal (RSW), with excellent graft survival and low rejection rates. There are no large randomized trials between alemtuzumab and rATG to determine whether one is better than the other. Anti-interleukin (IL)-2 receptor antibody induction and no induction in combination with a CNI, MMF or sirolimus, and prednisone have demonstrated excellent graft survival rates but are associated with a higher incidence of acute rejection. The efficacy of anti-IL-2 receptor antibodies or no induction in the setting of RSW is unproven. Both of the CNIs, ciclosporin and tacrolimus, are effective in preventing acute rejection in SPKT recipients; however, pancreas allograft survival may be better with tacrolimus. MMF is more effective than azathioprine in preventing acute rejection. Sirolimus appears to be effective in preventing acute rejection, but the combination of sirolimus with a CNI may accentuate the nephrotoxicity of the CNI. RSW with induction therapy is safe and effective in SPKT recipients, but longer follow-up data on outcomes are needed. Recent analysis of registry data shows that most transplant centres are using an induction agent followed by a combination of tacrolimus, MMF and corticosteroids in SPKT recipients.

Westernization and tobacco use among young people in Delhi, India. Soc Sci Med 2010; 71:891-7.

Abstract
Few studies have explored the relationship between acculturation and health in non-immigrant populations. The purpose of this study was to investigate the relationship between "westernization" and tobacco use among adolescents living in Delhi, India. A bi-dimensional model of acculturation was adapted for use in this study to examine (a) whether young people's identification with Western culture in this setting is related to tobacco use, and (b) whether their maintenance of more traditional Indian ways of living is related to tobacco use. Multiple types of tobacco commonly used in India (e.g., cigarettes, bidis, chewing tobacco) were considered. Socioeconomic status (SES), gender, and grade level were examined as potential effect modifiers of the relationship between "westernization" and tobacco use. The study was cross-sectional by design and included 3512 students in eighth and tenth grades who were enrolled in 14 Private (higher SES) and Government (lower SES) schools in Delhi, India. A self-report survey was used to collect information on tobacco use and "westernization." The results suggest that young people's identification with Western influences may increase their risk for tobacco use, while their maintenance of traditional Indian ways of living confers some protection. Importantly, these effects were independent of one another. Boys benefitted more from protective effects than girls, and tenth graders gained more consistent benefits than eighth graders in this regard, too. Negative effects associated with identification with Western ways of living were, in contrast, consistent across gender and grade level. The positive and negative effects of acculturation on adolescent tobacco use held for all tobacco products considered here. Future interventions designed to curb youth tobacco use in India may benefit by paying closer attention to cultural preferences of these young consumers.
