Abstract
PURPOSE/OBJECTIVE(S) Volumetric modulated arc therapy (VMAT)-based total body irradiation (TBI) with image guidance is a novel technique that is increasing in implementation. Compared to conventional TBI, VMAT-TBI offers favorable dose homogeneity, better organ-at-risk sparing, and enhanced patient comfort. However, whether these dosimetric advantages translate to improved clinical outcomes that justify the increased planning and delivery burden is not well understood. Only a single study of clinical outcomes of VMAT-TBI exists in the literature. We present the largest study to date of clinical outcomes of VMAT-TBI. MATERIALS/METHODS In this IRB-approved retrospective single-institution study, all patients treated with VMAT-TBI conditioning for allogeneic stem cell transplant, per the institution's published protocol, were identified. Dosimetric data were abstracted from the radiation oncology treatment planning system. Clinical data were abstracted from the electronic medical record. The primary outcome was six-month overall survival (6M OS) from the last day of TBI by Kaplan-Meier method. RESULTS Fifty-five patients (47 adult and 8 pediatric) were treated with VMAT-TBI between June 2020 and December 2022. All patients received conditioning chemotherapy with standard-dose TBI of 12 or 13.2 Gy in 8 twice-daily fractions. The PTV coverage (V95%) mean was 95.3% ± 1.2%. Mean lung dose was 9.5 Gy ± 0.6 for adult patients and 8.4 Gy ± 0.9 for pediatric patients. Mean lung dose rate was 18.0 cGy/min ± 4.4. Mean kidney dose was 5.9 Gy ± 0.6. Mean skin dose measured by MOSFET was 12.7 Gy ± 1.2. Median treatment time was 63 minutes (range: 53-104). Median follow-up was 7.7 months. At most recent follow-up, 78% of patients were alive. 6M OS was 82%. Common acute toxicities were fatigue (90.9% of patients, all grade 1-2), diarrhea (70.9%, all grade 1-2), nausea (76.4%, all grade 1-2), mucositis (60% grade 1-2, 12.7% grade 3, 1.8% grade 4, no grade 5), and xerostomia (54.5%, all grade 1). Mean pretreatment FEV1 was 98.3 percent of predicted (%p) ± 11.9%p and mean posttreatment FEV1 was 94.7%p ± 13.8%p. Mean pretreatment GFR was 101.4mL/min/1.73m² ± 17.4, mean 3-month posttreatment GFR was 92.4 ± 20.0, and mean 6-month posttreatment GFR was 97.5 ± 26.48. One patient experienced grade 2 pneumonitis; there were no other cases of pneumonitis. There were no acute grade 3+ toxicities aside from mucositis. Observed late toxicities were cataracts (7.3%, all grades 1-3) and hypothyroidism (12.7%, all grades 1-2). There were no grade 3+ late toxicities. Mild acute graft-versus-host disease (GVHD) was noted in 27.2% of patients and mild chronic GVHD was noted in 14.5% of patients, with no other cases of GVHD. CONCLUSION In the largest series to date, VMAT-TBI had excellent oncologic and toxicity outcomes. A randomized trial of VMAT-TBI versus standard TBI is warranted.

Abstract
PURPOSE/OBJECTIVE(S) The use of 5-fraction partial breast irradiation has been shown in a randomized trial to provide comparable rates of local control and reduced toxicities as compared to standard fractionation whole breast irradiation. The initial technique utilized a 2 cm expansion on the lumpectomy cavity (1 cm for clinical target volume [CTV], and 1 cm planning target volume [PTV]) without consistent image guidance (ex. cone beam computed tomography [CBCT]) or motion management recommendations. We present clinical outcomes using a 5-fraction image guided PBI technique (IG-PBI) to reduced target volumes for patients with early-stage breast cancer. MATERIALS/METHODS A retrospective review of an IRB approved institutional registry was performed to identify patients treated with IG-PBI. A total of 258 patients with early-stage breast cancer (Stage 0-IIA) receiving IG-PBI were identified. Patients received a dose of 30 Gy in 5 fractions delivered daily or every other day. An expansion of 1 cm on the lumpectomy cavity was used for those patients using deep inspiration breath hold (DIBH) while an expansion of 1.5 cm was utilized for those not using DIBH. All patients received daily CBCT. Plans were delivered using intensity-modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT) technique; while the prescription isodose line covered the PTV, the 26 Gy line was allowed to expand beyond the PTV. Kaplan-Meier analyses were used to assess rates of local control and survival. Patient demographics, stage, hormone therapy use, recurrence, mortality, and toxicity data were collected. Survival was analyzed with Kaplan-Meier curve. RESULTS Median age at diagnosis was 67 years (range 40-87) with a median follow-up of 29 months (IQR 22-40). Forty-six (18%) patients had in situ disease, 200 (78%) patients T1 tumors, and 12 (5%) patients had T2 tumors. Two hundred thirty-four (91%) patients were White, 15 (6%) were Black, and 9 (4%) were other races. One hundred ninety-six (76%) patients received endocrine therapy, and 16 (6%) patients received chemotherapy. Thirty-two (12%) patients developed grade 1 dermatitis and no grade 2 events were observed. One (0.4%) patient had a cardiac event (aortic stenosis) 19 months after breast radiotherapy. At last follow-up, one (0.4%) patient had a local recurrence and one (0.4%) developed a distant metastasis, with no regional nodal failures. Overall, 4 (1.5%) patients had died, all due to other causes. At 3 years, locoregional control was 99.4%. CONCLUSION Outcomes with IG-PBI demonstrate low rates of local recurrence and limited toxicity. The use of reduced target volumes is not associated with increased rates of local recurrence.

Abstract
PURPOSE/OBJECTIVE(S) Accelerated partial breast irradiation (APBI) represents an alternative to whole breast irradiation (WBI), reducing the target volume and potentially treatment duration. APBI delivered in 5 fractions with intensity modulated radiation therapy (IMRT) has been shown to have comparable outcomes to WBI with reduced toxicity profiles. In contrast, intraoperative radiation therapy (IORT) offers patients the potential to complete adjuvant radiation therapy in a single treatment. While early data were initially promising, concerns regarding long-term rates of local recurrence exist. We present a comparison of 5 fraction APBI versus IORT. MATERIALS/METHODS We performed a retrospective review of 473 patients with early-stage breast cancer (Stage 0-IIA) treated at a single institution with 258 receiving APBI and 215 IORT from October 2011 to May 2021. APBI patients received 30 Gy in 5 fractions delivered with IMRT daily or every other day. IORT patients received 20 Gy in 1 fraction prescribed to the applicator surface delivered at the time of surgery. Kaplan-Meier analysis was used to estimate locoregional control rates and overall survival among the 2 groups. RESULTS Mean age was 70.7 years old (IQR:67-74) for the IORT patients and 66.6 years old (IQR:62-72) for the APBI patients (p<0.001). Median follow up was 5.7 years for IORT patients and 2.4 years for APBI patients (p<0.001). For IORT patients, 11%/83.5%/5.5% of patients and for APBI 17.8%/77.5%/4.7% of patients had Tis/T1/T2 disease (p = 0.005). With regards to adjuvant therapies, 79%/76% of IORT/APBI patients were offered endocrine therapy (p = 0.50) and 1.4%/6.2% chemotherapy (p = 0.008). Recurrence at any time was seen in 7.9% (n = 17) of patients receiving IORT as compared to 0.8% (n = 2) of patients receiving APBI. APBI was however no differences in recurrence free survival (92.6% vs. 98.5%, p = .079) or overall survival were noted (92.8% vs. 95.1%, p = 0.99). CONCLUSION In a series of almost 500 patients with stage 0-IIA breast cancer, IORT was associated with higher rates of locoregional recurrence compared to APBI with no survival difference at 5 years. These outcomes, consistent with other series and current guidelines, suggest a limited role for IORT as monotherapy following breast conserving surgery.

Abstract
IMPORTANCE Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. OBJECTIVE To determine whether hydrocortisone improves outcome for patients with severe COVID-19. DESIGN, SETTING, AND PARTICIPANTS An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. INTERVENTIONS The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). MAIN OUTCOMES AND MEASURES The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). RESULTS After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. CONCLUSIONS AND RELEVANCE Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions.

Abstract
IMPORTANCE Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. OBJECTIVE To determine whether hydrocortisone improves outcome for patients with severe COVID-19. DESIGN, SETTING, AND PARTICIPANTS An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. INTERVENTIONS The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). MAIN OUTCOMES AND MEASURES The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). RESULTS After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. CONCLUSIONS AND RELEVANCE Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02735707.

Abstract
Background In acute respiratory distress syndrome (ARDS) unrelated to COVID-19, two phenotypes, based on the severity of systemic inflammation (hyperinflammatory and hypoinflammatory), have been described. The hyperinflammatory phenotype is known to be associated with increased multiorgan failure and mortality. In this study, we aimed to identify these phenotypes in COVID-19-related ARDS. Methods In this prospective observational study done at two UK intensive care units, we recruited patients with ARDS due to COVID-19. Demographic, clinical, and laboratory data were collected at baseline. Plasma samples were analysed for interleukin-6 (IL-6) and soluble tumour necrosis factor receptor superfamily member 1A (TNFR1) using a novel point-of-care assay. A parsimonious regression classifier model was used to calculate the probability for the hyperinflammatory phenotype in COVID-19 using IL-6, soluble TNFR1, and bicarbonate levels. Data from this cohort was compared with patients with ARDS due to causes other than COVID-19 recruited to a previous UK multicentre, randomised controlled trial of simvastatin (HARP-2). Findings Between March 17 and April 25, 2020, 39 patients were recruited to the study. Median ratio of partial pressure of arterial oxygen to fractional concentration of oxygen in inspired air (PaO2/FiO2) was 18 kpa (IQR 15–21) and acute physiology and chronic health evaluation II score was 12 (10–16). 17 (44%) of 39 patients had died by day 28 of the study. Compared with survivors, patients who died were older and had lower PaO2/FiO2. The median probability for the hyperinflammatory phenotype was 0·03 (IQR 0·01–0·2). Depending on the probability cutoff used to assign class, the prevalence of the hyperinflammatory phenotype was between four (10%) and eight (21%) of 39, which is lower than the proportion of patients with the hyperinflammatory phenotype in HARP-2 (186 [35%] of 539). Using the Youden index cutoff (0·274) to classify phenotype, five (63%) of eight patients with the hyperinflammatory phenotype and 12 (39%) of 31 with the hypoinflammatory phenotype died. Compared with matched patients recruited to HARP-2, levels of IL-6 were similar in our cohort, whereas soluble TNFR1 was significantly lower in patients with COVID-19-associated ARDS. Interpretation In this exploratory analysis of 39 patients, ARDS due to COVID-19 was not associated with higher systemic inflammation and was associated with a lower prevalence of the hyperinflammatory phenotype than that observed in historical ARDS data. This finding suggests that the excess mortality observed in COVID-19-related ARDS is unlikely to be due to the upregulation of inflammatory pathways described by the parsimonious model.

Abstract
In sickle cell disease, cardiopulmonary bypass may induce red cell sickling. Partial exchange transfusion reduces the circulating haemoglobin S level. We report the management of a child with sickle cell disease who required surgical closure of a ventricular septal defect. Preoperative exchange transfusion of 50% of the total blood volume was performed with fresh packed red cells over three days. Further exchange transfusion was performed as cardiopulmonary bypass commenced. The haemoglobin S level was reduced from 76% to 37%. The blood removed from the patient during the exchanges was processed allowing storage and re-infusion of the patient's plasma and platelets. Combined preoperative and intraoperative exchange transfusions, instead of a single stage 50% volume exchange, was effective and potentially avoids larger haemodynamic effects. Cardiopulmonary bypass was conducted at normothermia and cold cardioplegia was avoided (fibrillatory arrest was used during the surgical repair).

Abstract
Invasive fungal infections in solid organ transplant recipients are associated with significant morbidity and mortality. Of these fungal infections, mucormycosis presents as an aggressive, frequently fatal angioinvasive infection. Immunocompromised hosts and diabetes are important risk factors. These infections are frequently difficult to diagnose. A high index of suspicion in the appropriate setting and early, aggressive treatment with the newer antifungal agents have altered the previously grave prognosis. We present the first reported case of cavitating pulmonary mucormycosis in a renal transplant recipient caused by an unusual species of Mucorales. The patient was treated with a combination of lobectomy and antifungal treatment comprising of amphotericin B and posaconazole. He remains free of disease recurrence on monotherapy with posaconazole.

Abstract
Bluetongue virus (BTV) is neurotropic in nature, especially in ruminant fetuses and in-utero infection results in abortion and congenital brain malformations. The aim of the present study was to compare the neuropathogenicity of major Indian BTV serotypes 1, 2, 10, 16 and 23 by gross and histopathological lesions and virus distribution in experimentally infected neonatal BALB/c mice. Each BTV serotype (20 μl of inoculum containing 1 × 105 tissue culture infectious dose [TCID]50/ml of virus) was inoculated intracerebrally into 3-day-old mice, while a control group was inoculated with mock-infected cell culture medium. Infection with BTV serotypes 1, 2 and 23 led to 65-70% mortality at 7-9 days post infection (dpi) and caused severe necrotizing encephalitis with neurodegenerative changes in neurons, swelling and proliferation of vascular endothelial cells in the cerebral cortex, cerebellum, midbrain and brainstem. In contrast, infection with BTV serotypes 10 and 16 led to 25-30% mortality at 9-11 dpi and caused mild neuropathological lesions. BTV antigen was detected by immunohistochemistry, direct fluorescence antibody technique and confocal microscopy in the cytoplasm of neuronal cells of the hippocampus, grey matter of the cerebral cortex and vascular endothelial cells in the midbrain and brainstem of BTV-1, -2, -10, -16 and -23 infected groups from 3 to 20 dpi. BTV nucleic acid was detected in the infected brain tissues from as early as 24 h up to 20 dpi by VP7 gene segment-based one-step reverse transcriptase polymerase chain reaction. This study of the relative neurovirulence of BTV serotypes is likely to help design suitable vaccination and control strategies for the disease.

Abstract
AIMS To investigate the impact of pelvic radiation on survival in patients with uterine clear cell carcinoma (UCC) who received adjuvant chemotherapy. MATERIALS AND METHODS Patients with stage I-IV UCC who had undergone surgery and chemotherapy were identified from the Surveillance, Epidemiology, and End Results (SEER) programm 2000-2009. Patients were divided into those who received only chemotherapy and those who received both chemotherapy and radiation therapy. Kaplan-Meier curves and Cox regression models were used for analysis. RESULTS Of the 317 patients included, 195 (62%) were in the chemotherapy only group and 122 (38%) were in the chemotherapy and radiation therapy group. Pelvic radiation was associated with significant improvement in overall survival (median 88 versus 25 months, 5 year survival: 58% versus 33%, P<0.001) in the chemotherapy and radiation therapy group compared with the chemotherapy only group for the entire cohort. On subset analysis, chemotherapy and radiation therapy was associated with improved overall survival in late stage disease (III-IV) (5 year 54% versus 22%, P<0.001) compared with the chemotherapy only group, whereas in stage I-II UCC, there was no difference in overall survival between the chemotherapy and radiotherapy group and the chemotherapy only group (5 year 65% versus 67%, P=0.69). In multivariable analysis, pelvic radiation was associated with improved survival in patients with late stage disease (hazard ratio 0.57, 95% confidence interval 0.35-0.94, P=0.03) but not for early stage disease (hazard ratio 0.81, 95% confidence interval 0.33-2.0, P=0.65). Other significant predictors were advanced stage, positive cytology and extensive lymphadenectomy. CONCLUSIONS Radiation was associated with significant improvement in survival in advanced stage UCC, but not in early stage UCC. These data support the beneficial role of radiation therapy in UCC, especially in patients with advanced stage disease.

Abstract
BACKGROUND This study aimed to assess the early caries experience and the efficacy of a community based dental referral pathway in preschool refugees in Western Australia. METHODS Preschool refugee children referred to the Western Australian paediatric hospital Refugee Health Clinic were prospectively screened for caries by a paediatric dentist before being referred to community dental clinics. Dental forms and medical records were audited to assess decayed, missing and filled teeth (dmft), medical data and dental services engagement. Poisson regression analysis determined the contribution of count variables to the final model. RESULTS Among the 105 screened children (54% male, median age 3.2 years, 41% Burmese), community dental clinic engagement was low (46%, n=48). Of the 62% with caries (n=65/105, mean dmft 5.2, SD 4.1), 45% were recommended for specialist dental services and 48% were treated. After adjustment for age, gender and total number of teeth, caries incidence was significantly associated with BMI-for-age Z score (p=0.02). CONCLUSIONS Preschool refugee caries burden was high. The community dental referral pathway was ineffective compared to co-located intersectorial dental screening. Specialist dental service needs are high in this cohort and require a targeted approach.

Abstract
Consistency in group level (continuity) and individual level (stability) was examined longitudinally for caregiving principles (structure and attunement) and cognitions (categorical thinking, perspectivist thinking, complexity of thought) in mothers of preterm and term infants from birth to 5 months old. Attunement was continuous and stable in mothers of preterm and term infants. Structure was continuous in both groups but stable only in mothers of term infants. Complexity of thought was continuous in both groups, perspectivist thinking increased in both groups but only for first-time mothers, and categorical thinking increased only in mothers of preterm infants. Categorical thinking, perspectivist thinking, and complexity of thought were stable in mothers of both preterm and term infants.
The aims of this study were to examine and compare the development of parenting cognitions and principles in mothers following preterm and term deliveries. Parenting cognitions about child development, including thinking that is restricted to single causes and single outcomes (categorical thinking) and thinking that takes into account multiple perspectives (perspectivist thinking), have been shown to relate to child outcomes. Parenting principles about using routines (structure) or infant cues (attunement) to guide daily caregiving have been shown to relate to caregiving practices. We investigated the continuity and stability of parenting cognitions and principles in the days following birth to 5 months postpartum for mothers of infants born term and preterm. All parenting cognitions were stable across time. Categorical thinking increased at a group level across time in mothers of preterm, but not term, infants. Perspectivist thinking increased at a group level for first-time mothers (regardless of birth status) and tended to be lower in mothers of preterm infants. Structure at birth did not predict later structure (and so was unstable) in mothers of preterm, but not term, infants and neither group changed in mean level across time. Attunement was consistent across time in both groups of mothers. These results indicate that prematurity has multiple, diverse effects on parenting beliefs, which may in turn influence maternal behavior and child outcomes.

Abstract
In rodents, many social behaviors are driven by the sense of smell. The vomeronasal organ (VNO), part of the accessory olfactory system mediates many of these chemically driven behaviors. The VNO is heavily vascularized, and is readily accessible to circulating peptide or steroid hormones. Potentially, this allows circulating hormones to alter behavior through modulating the output of the primary sensory neurons in the VNO, the vomeronasal sensory neurons (VSNs). Based on this, we hypothesized that steroid hormones, in particular 17β-estradiol, would modulate activity of VSNs. In this paper, we show that the estrogen receptors, GPR30 and ERα, were present in VSNs and that estradiol may be synthesized locally in the VNO. Our results also showed that 17β-estradiol decreased responses of isolated VSNs to dilute urine, a potent natural stimulus, with respect to current amplitudes and depolarization. Further, 17β-estradiol increased the latency of the first action potential (AP) and the AP amplitude. Additionally, calcium responses to sulfated steroids (present in the low molecular weight fraction of urine) that act as ligands for apical vomeronasal receptors were decreased by 17β-estradiol. In conclusion, we show that estradiol modulates odorant responses mediated by VSNs and hence paves the way for future studies to better understand the mechanisms by which odorant mediated behavior is altered by endocrine status of the animal.

Abstract
OBJECTIVES This study evaluates the interobserver variation in parotid gland delineation and its impact on intensity-modulated radiotherapy (IMRT) solutions. METHODS The CT volumetric data sets of 10 patients with oropharyngeal squamous cell carcinoma who had been treated with parotid-sparing IMRT were used. Four radiation oncologists and three radiologists delineated the parotid gland that had been spared using IMRT. The dose-volume histogram (DVH) for each study contour was calculated using the IMRT plan actually delivered for that patient. This was compared with the original DVH obtained when the plan was used clinically. RESULTS 70 study contours were analysed. The mean parotid dose achieved during the actual treatment was within 10% of 24 Gy for all cases. Using the study contours, the mean parotid dose obtained was within 10% of 24 Gy for only 53% of volumes by radiation oncologists and 55% of volumes by radiologists. The parotid DVHs of 46% of the study contours were sufficiently different from those used clinically, such that a different IMRT plan would have been produced. CONCLUSION Interobserver variation in parotid gland delineation is significant. Further studies are required to determine ways of improving the interobserver consistency in parotid gland definition.

Abstract
During 1960-80 dengue disease profile in India was mild despite circulation of all four serotypes of dengue virus (DENV). Increase in disease severity with a concomitant change in the population of DENV-1 and 2 have been reported since then. To determine population dynamics of DENV-3 and 4, the envelope (E) gene sequence was determined for 16 Indian isolates of DENV-3 and 11 of DENV-4 and analyzed together with 97 DENV-3 and 43 DENV-4 global sequences. All Indian DENV-3 isolates belonged to genotype III, lineages C, D, E and F. Lineage F was newly identified and represented non-circulating viruses. Three non-conservative amino acid changes in domain I, II & III were identified during the transition from lineages F/E, associated with mild disease, to A-D, associated with severe disease. For DENV-4, the current viruses clustered in genotype I, lineage C, whilst the isolates from 1960s formed the new genotype V. A 1979 Indian isolate of DENV-4 was found to be an inter-genotypic recombinant of Sri Lankan isolate (1978) of genotype I and Indian isolate (1961) of genotype V. The rates of nucleotide substitution and time to the most recent common ancestor (tMRCA) estimated for DENV-3 (1782-1934) and DENV-4 (1719-1931) were similar to earlier reports. However, the divergence time for genotype III of DENV-3, 1938-1963, was a more accurate estimate with the inclusion of Indian isolates from the 1960s. By phylogeographical analysis it was revealed that DENV-3 GIII viruses emerged from India and evolved through Sri Lanka whilst DENV-4 emerged and dispersed from India. The present study demonstrates the crucial role that India/Sri Lanka have played in the evolution and dispersion of the major genotypes, GIII of DENV-3 and GI of DENV-4 which are more virulent and show higher dissemination potential.

Abstract
With the changing epidemiology, outbreaks of Hepatitis A Virus (HAV) have been reported from different parts of India. To characterize HAV strains circulating in India (1995-2008), 6 full genome sequences of the predominant genotype, IIIA, were determined. Further, applying the Bayesian Markov Chain Monte Carlo (MCMC) framework to the full genomes of Indian HAV strains as well as other global strains (human as well as simian), we derived the mean nucleotide substitution rate and evolutionary timescales with emphasis on the age of genotype III and IIIA strains. The genomic length of all the 6 HAV isolates was 7464 nt excluding the poly A tract. Phylogenetic analysis confirmed that all the Indian isolates were close to Nor-21 (AJ299464) and HMH (AY644337) of subgenotype IIIA. The ORF of the isolates when compared within genotype III at amino acid level showed a highly conserved pattern. Under the best fit expansion population relaxed molecular clock model, the estimated mean substitution rate of the HAV full genomes (human and simian strains) was 1.73 x 10(-4) substitutions/site/year based on which the earliest transmission of HAV from simian to humans is estimated to have occurred about 3564 years ago. The mean substitution rate within human HAV full genomes under the same model was estimated to be 1.99 x 10(-4) substitutions/site/year. With this the mean age of genotype III strains was estimated to be 592 years while that of genotype IIIA was estimated to be 202 years. The time to the most common recent ancestor (tMRCA) of the Indian genotype IIIA isolates was calculated to be 116 years.
