Abstract
PURPOSE Currently, the anal fistula treatment which optimises healing and preserves bowel continence remains unclear. The aim of our study was to compare the relative efficacy of different surgical treatments for AF through a network meta-analysis. METHODS Systematic searches of MEDLINE, EMBASE and CENTRAL databases up to October 2022 identified randomised controlled trials (RCTs) comparing surgical treatments for anal fistulae. Fistulae were classified as simple (inter-sphincteric or low trans-sphincteric fistulae crossing less than 30% of the external anal sphincter (EAS)) and complex (high trans-sphincteric fistulae involving more than 30% of the EAS). Treatments evaluated in only one trial were excluded from the primary analyses to minimise bias. The primary outcomes were rates of success in achieving AF healing and bowel incontinence. RESULTS Fifty-two RCTs were included. Of the 14 treatments considered, there were no significant differences regarding short-term (6 months or less postoperatively) and long-term (more than 6 months postoperatively) success rates between any of the treatments in patients with both simple and complex anal fistula. Ligation of the inter-sphincteric fistula tract (LIFT) ranked best for minimising bowel incontinence in simple (99.1% of comparisons; 3 trials, n = 70 patients) and complex anal fistula (86.2% of comparisons; 3 trials, n = 102 patients). CONCLUSIONS There is insufficient evidence in existing RCTs to recommend one treatment over another regarding their short and long-term efficacy in successfully facilitating healing of both simple and complex anal fistulae. However, LIFT appears to be associated with the least impairment of bowel continence, irrespective of AF classification.

Abstract
Importance Advances in cancer research and treatment access have led to decreasing cancer mortality in the US; however, cancer remains the leading cause of death among Hispanic individuals. Objective To evaluate longitudinal cancer mortality trends from 1999 to 2020 among Hispanic individuals by demographic characteristics and to compare age-adjusted cancer death rates between the Hispanic population and other racial and ethnic populations during 2000, 2010, and 2020. Design, Setting, and Participants This cross-sectional study obtained age-adjusted cancer death rates among Hispanic individuals of all ages between January 1999 and December 2020, using the Centers for Disease Control and Prevention WONDER database. Cancer death rates in other racial and ethnic populations were extracted for 2000, 2010, and 2020. Data were analyzed from October 2021 to December 2022. Exposures Age, gender, race, ethnicity, cancer type, and US census region. Main Outcomes and Measures Trends and average annual percent changes (AAPCs) in age-adjusted cancer-specific mortality (CSM) rates among Hispanic individuals were estimated by cancer type, age, gender, and region. Results From 1999 to 2020, 12 644 869 patients died of cancer in the US, of whom 690 677 (5.5%) were Hispanic; 58 783 (0.5%) were non-Hispanic American Indian or Alaska Native; 305 386 (2.4%), non-Hispanic Asian or Pacific Islander; 1 439 259 (11.4%), non-Hispanic Black or African American; and 10 124 361 (80.1%), non-Hispanic White. For 26 403 patients (0.2%), no ethnicity was stated. The overall CSM rate among Hispanic individuals decreased by 1.3% (95% CI, 1.2%-1.3%) annually. Overall CSM rate decreased more for Hispanic men (AAPC, -1.6%; 95% CI, -1.7% to -1.5%) compared with women (AAPC, -1.0%; 95% CI, -1.0% to -0.9%). While death rates among Hispanic individuals decreased for most cancer types, mortality rates for liver cancer (AAPC, 1.0%; 95% CI, 0.6%-1.4%) increased among Hispanic men, and rates of liver (AAPC, 1.0%; 95% CI, 0.8%-1.3%), pancreas (AAPC, 0.2%; 95% CI, 0.1%-0.4%), and uterine (AAPC, 1.6%; 95% CI, 1.0%-2.3%) cancers increased among Hispanic women. Overall CSM rates increased for Hispanic men aged 25 to 34 years (AAPC, 0.7%; 95% CI, 0.3%-1.1%). By US region, liver cancer mortality rates increased significantly in the West for both Hispanic men (AAPC, 1.6%; 95% CI, 0.9%-2.2%) and Hispanic women (AAPC, 1.5%; 95% CI, 1.1%-1.9%). There were differential findings in mortality rates when comparing Hispanic individuals with individuals belonging to other racial and ethnic populations. Conclusions and Relevance In this cross-sectional study, despite overall CSM decreasing over 2 decades among Hispanic individuals, disaggregation of data demonstrated that rates of liver cancer deaths among Hispanic men and women and pancreas and uterine cancer deaths among Hispanic women increased from 1999 to 2020. There were also disparities in CSM rates among age groups and US regions. The findings suggest that sustainable solutions need to be implemented to reverse these trends among Hispanic populations.

Type of funding sources: None.
Background
Obesity and low hemoglobin content (Hgb <13 and <12 g/dL, men/women, respectively) are commonly observed in patients with heart failure and reduced ejection fraction (HFrEF). This overlap typically yields reductions in peak exercise oxygen uptake (V̇O2peak) which exceed those observed in both non-obese and obese patients exhibiting normal Hgb levels. However, when matched for body size, non-obese patients exhibiting low Hgb levels also demonstrate worse V̇O2peak impairment than normal Hgb level counterparts. To date, it is unclear whether the effect of Hgb level on V̇O2peak also affects the association between V̇O2peak and mortality risk in both non-obese and obese patients.
Purpose
To assess whether V̇O2peak that is predictive of mortality risk is directly impacted by Hgb level regardless of whether a patient is non-obese or obese.
Methods
Adults with HFrEF (n=346; LVEF ≤40%; 76% men) completed cardiopulmonary exercise testing (CPET) as part of routine clinical management. The majority of patients performed Naughton or Modified Naughton CPET protocols. Patients with a BMI ≥30 kg/m2 were classified as obese (n=135; 81% men). Patients were followed up to one-year for the endpoint of all-cause mortality.
Results
Age (63±7 vs 61±8 yrs), total body weight (77±13 vs 107±15 kg), BMI (25.2±3.0 vs 34.5±4.0 kg/m2), and Hgb (12.6±1.8 vs 13.1±1.8 g/dL) differed between non-obese and obese patients (all P<0.01), respectively. There were no significant differences between non-obese and obese patients for % men (73 vs 81 %), % ischemic etiology (46 vs 42 %), and LVEF (23±8 vs 24±9 % (all P>0.05), respectively. Peak exercise RER (1.13±0.12 vs 1.10±0.11), V̇O2peak (13.0±3.8 vs 11.9±3.3 mL/kg/min), and absolute V̇O2peak (1.01±0.37 vs 1.28±0.40 L/min) differed between non-obese and obese patients (all P<0.02), respectively. Over the 1-year tracking period, 25 and 13 deaths were observed and crude survival was 85% and 88% in non-obese and obese patients (Log-rank, P=0.465), respectively. In obese patients, V̇O2peak and Hgb interacted (χ2=4.855, P=0.028), resulting in up to a 22% reduction in all-cause mortality risk per 1.0 mL/kg/min rise in V̇O2peak for Hgb levels ≤13.1 g/dL. In non-obese patients, V̇O2peak and Hgb did not interact (χ2=0.001, P=0.977), and when Hgb was removed from the Cox regression, this resulted in up to a 29% reduction in all-cause mortality risk per 1.0 mL/kg/min rise in V̇O2peak (χ2=23.618, P<0.001).
Conclusion
Demonstrating low Hgb and V̇O2peak levels yields comparable effects on all-cause mortality risk in non-obese and obese patients. However, at normal Hgb levels, V̇O2peak loses prognostic value in the obese, suggesting for these patients other CPET variables should be used to complement V̇O2peak when CPET is built into risk stratification models.

Abstract
Keeping track of a hydrated proton in dynamics simulations is important and nontrivial. Here, we report two revised algorithms for the proton indicator, a pseudo-atom whose position approximates the location of an excess proton diffusing via the Grotthuss mechanism in aqueous solution. The new methods describe the delocalized proton as a structural defect. Encouragingly, in test simulations of a hydrated proton in bulk water, the new algorithms substantially outperform the original scheme by significantly reducing large displacements in the indicator positions upon donor switch, yielding smoother trajectories that effectively track the movement of the solvated proton.

Abstract
Background Multiple treatments for early–moderate grade symptomatic haemorrhoids currently exist, each associated with their respective efficacy, complications, and risks. The aim of this study was to compare the relative clinical outcomes and effectiveness of interventional treatments for grade II–III haemorrhoids. Methods A systematic review was conducted according to PRISMA criteria for all the RCTs published between 1980 and 2020; manuscripts were identified using the MEDLINE, Embase, and CENTRAL databases. Inclusion criteria were RCTs comparing procedural interventions for grade II–III haemorrhoids. Primary outcomes of interest were: symptom recurrence at a minimum follow-up of 6 weeks, postprocedural pain measured on a visual analogue scale (VAS) on day 1, and postprocedural complications (bleeding, urinary retention, and bowel incontinence). After bias assessment and heterogeneity analysis, a Bayesian network meta-analysis was performed. Results Seventy-nine RCTs were identified, including 9232 patients. Fourteen different treatments were analysed in the network meta-analysis. Overall, there were 59 RCTs (73 per cent) judged as being at high risk of bias, and the greatest risk was in the domain measurement of outcome. Variable amounts of heterogeneity were detected in direct treatment comparisons, in particular for symptom recurrence and postprocedural pain. Recurrence of haemorrhoidal symptoms was reported by 54 studies, involving 7026 patients and 14 treatments. Closed haemorrhoidectomy had the lowest recurrence risk, followed by open haemorrhoidectomy, suture ligation with mucopexy, stapled haemorrhoidopexy, and Doppler-guided haemorrhoid artery ligation (DG-HAL) with mucopexy. Pain was reported in 34 studies involving 3812 patients and 11 treatments. Direct current electrotherapy, DG-HAL with mucopexy, and infrared coagulation yielded the lowest pain scores. Postprocedural bleeding was recorded in 46 studies involving 5696 patients and 14 treatments. Open haemorrhoidectomy had the greatest risk of postprocedural bleeding, followed by stapled haemorrhoidopexy and closed haemorrhoidectomy. Urinary retention was reported in 30 studies comparing 10 treatments involving 3116 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had significantly higher odds of urinary retention than rubber band ligation and DG-HAL with mucopexy. Nine studies reported bowel incontinence comparing five treatments involving 1269 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had the highest probability of bowel incontinence. Conclusion Open and closed haemorrhoidectomy, and stapled haemorrhoidopexy were associated with worse pain, and more postprocedural bleeding, urinary retention, and bowel incontinence, but had the lowest rates of symptom recurrence. The risks and benefits of each treatment should be discussed with patients before a decision is made.

Abstract
Purpose: The concept of health locus of control is important because of its relation with health attitudes, behavior and coping styles. This study was done to compare the locus of control orientation and oral health status of tobacco users with that of non-tobacco users.
Method: This cross-sectional study was conducted on rural population in southern Indian state. All the participants were interviewed to gather data on their socio-demographic correlates, oral health related behavior and health locus of control with the help of a pre-tested questionnaire. Clinical examination was done using WHO oral health assessment form (1997).Main outcome measures were Locus of Control, Oral Health (dental caries status and periodontal status).
Results: Tobacco users were found to score lower on the dimension of Internality and higher on the Chance dimension compared to non-tobacco users. The prevalence and severity of periodontal disease was significantly higher in tobacco users than non-tobacco users irrespective of age and socioeconomic strata.
Conclusion: It was also concluded that non-tobacco users had internal orientation to health locus of control thereby being important behavioral factor controlling health in this group.Findings also demonstrated significant association between tobacco usage and adverse periodontal health.

Abstract
Introduction and Aim: Prenatal androgens are believed to be one of the probable etiological factors influencing intellectual development of an individual. In-utero testosterone exposure has been thought to affect the digit ratio which is the ratio of lengths of index finger and ring finger (2D:4D). In the present work we intended to study the correlation of 2D:4D with numerical and verbal intelligence believed to be variable among genders. The aim of our study was to find the association of 2D:4D with Verbal Intelligence and Numerical Intelligence in a sample of medical students.
Materials and Methods: This study was conducted in a sample of medical students. 44 female and 44 male students participated in the study. 2D:4D measurements were made using standard procedure after which the participants completed a questionnaire containing 20 questions each to test numerical and verbal intelligence.
Results: In this study, Males were found to have a lower 2D:4D when compared to females. Individuals with lower 2D:4D in their right-hand were seen to have lower verbal intelligence and higher numerical intelligence thus suggesting that males are born with better numerical intelligence and females with greater verbal intelligence.
Conclusion: Digit ratio can be considered as a valuable indicator of individual differences in terms of intelligence, although the exact role of testosterone on brain to cause variation in these cognitive domains is yet to be clearly understood.

Abstract
Introduction Delayed gastric emptying (DGE) is frequent after pancreaticoduodenectomy (PD). Several RCTs have explored operative strategies to minimize DGE, however, the optimal combination of gastric resection approach, anastomotic route, configuration and the use of enteroenterostomy remains unclear. Methods MEDLINE, Embase and CENTRAL databases were systematically searched for RCTs comparing gastric resection (classic Whipple, pylorus-resecting, pylorus-preserving), anastomotic route (antecolic, retrocolic), configuration (loop gastroenterostomy/Billroth II, Roux-en-Y), and use of enteroenterostomy (Braun). A random-effects, Bayesian network meta-analysis with non-informative priors was conducted to determine the optimal combination of approaches to PD for minimizing DGE. Results Twenty-four RCTs, including 2526 patients and 14 approaches were included. There was some heterogeneity, although inconsistency was low. The overall incidence of DGE was 25.6 per cent (647 patients). Pylorus-resecting, antecolic, Billroth II with Braun enteroenterostomy was associated with the lowest rates of DGE and ranked the best in 35 per cent of comparisons. Classic Whipple, retrocolic, Billroth II with Braun ranked the worst for DGE in 32 per cent of comparisons. Pairwise meta-analysis of retrocolic versus antecolic route for gastrojejunostomy found increased risk of DGE with the retrocolic route (odds ratio 2.10, 95 per cent credibility interval (cr.i.) 0.92 to 4.70). Pairwise meta-analysis of enteroenterostomy found a trend towards lower DGE rates when this was used (odds ratio 1.90, 95 per cent cr.i. 0.92 to 3.90). Having a Braun enteroenterostomy ranked the best in 96 per cent of comparisons. Conclusion Based on existing RCT evidence, a pylorus-resecting, antecolic, Billroth II with Braun enteroenterostomy seems to be associated with the lowest rates of DGE.

Abstract
The emergence of new synthetic cathinones continues to be a matter of public health concern. In fact, they are quickly replaced by new structurally related alternatives. The main goal of the present study was to characterize the pharmacological profile, the psychostimulant and rewarding properties of novel cathinones (pentedrone, N-ethyl-pentedrone, α-PVP, N,N-diethyl-pentedrone and α-PpVP) which only differs in their amino terminal substitution. Rat synaptosomes were used for [3H]dopamine uptake experiments. HEK293 transfected cells (hDAT, hSERT, hOCT; human dopamine, serotonin and organic cation transporter) were also used for [3H]monoamine uptake and transporter binding assays. Molecular docking was used to investigate the effect of the amino substitutions on the biological activity. Hyperlocomotion and conditioned place preference paradigm were used in order to study the psychostimulant and rewarding effects in mice. All compounds tested are potent inhibitors of DAT with very low affinity for SERT, hOCT-2 and -3, and their potency for inhibiting DAT increased when the amino-substituent expanded from a methyl to either an ethyl-, a pyrrolidine- or a piperidine-ring. Regarding the in vivo results, all the compounds induced an increase in locomotor activity and possess rewarding properties. Results also showed a significant correlation between predicted binding affinities by molecular docking and affinity constants (Ki) for hDAT as well as the cLogP of their amino-substituent with their hDAT/hSERT ratios. Our study demonstrates the role of the amino-substituent in the pharmacological profile of novel synthetic cathinones as well as their potency inhibiting DA uptake and ability to induce psychostimulant and rewarding effects in mice.

Abstract
INTRODUCTION Oral health affects quality of life. Many studies have investigated the factors associated with oral health-related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services. OBJECTIVES To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y. METHODS A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3. RESULTS There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India. CONCLUSIONS Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts. KNOWLEDGE TRANSFER STATEMENT This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

Abstract
Abstract
Introduction
Recent studies have shown an association of low Vitamin D levels and severity of RLS symptoms. However, effect of treatment of Vit D deficiency on RLS symptoms was not reported, nor were other exacerbating factors for RLS such as iron deficiency or OSA addressed in prior studies, but have been addressed in our study.
Methods
This is an ongoing study at the JFKMC Sleep Clinic. Eligible Patients with RLS include those with vitamin D 25,hydroxy deficiency (<20 ng/ml), or insufficiency (<30 ng/ml). Such patients will be enrolled in the study after comorbid conditions like iron deficiency and OSA have been adequately corrected. Randomization of the patients will be done by the JFK pharmacy so the patient and provider are blinded to the substance. Substance A or B could be either Vitamin D3 Capsule 50,000 IU, or placebo. Each patient takes A for 6 weeks and then crosses over to B for 6 weeks. Weekly iRLS questionnaires will be collected. Actiwatch Device, to assess activity count per minute, will be worn on the ankle at night for one week time periods: at baseline, at end of 6 weeks of taking A and then at the end of 6 weeks of taking B. Vitamin D levels will also be assessed after each course of supplementation and correlated with subjective and objective findings.
Results
Between July 7, 2019 to current, 50 consecutive patients seen in sleep clinic with RLS were assessed for vitamin D levels. Ages ranged from 23-86 years. 27 patients were female (54%). Two patients met inclusion criteria and have started their 13-week study.
Conclusion
This study will help to establish the role of Vitamin D deficiency as a risk factor for RLS, independent of ferritin levels, and comorbid OSA, in affected individuals. This may help to discover a potentially treatable form of RLS.

Abstract
Abstract
Introduction
Obstructive sleep apnea (OSA) has been associated with adverse outcomes in patients with stroke. While data is limited, it suggests that treatment of OSA may improve neurological recovery. With this quality improvement (QI) project, we aim to develop an interprofessional-team workflow process for screening and correction of OSA in acute ischemic stroke, with the goal to improve outcomes of neurological recovery.
Methods
This is an ongoing study to screen all eligible patients admitted to JFK Medical Center stroke unit, with MRI-proven Supratentorial acute ischemic stroke. The patients are screened using an overnight Pulse Oximetry test. A 3% oxygen desaturation index (ODI) of ≥10/hr or 4% ODI of ≥ 5/hr is considered at high risk for OSA. Such Patients will receive nocturnal Auto-adjusting BIPAP therapy during their acute care stay, for up to 5 days, for at least 4 hours per night. Eligible Patients who refused BiPAP therapy or were non-compliant will be considered as a controls. Baseline NIH stroke scale (NIHSS), and bilateral MCA mean flow velocity (MFV) in the morning, by transcranial doppler (TCD) will be assessed at baseline for cases and controls, and after BiPAP therapy, for the case group. The two groups of patients will also be compared in terms of Modified Rankin Scale at time of discharge and at phone follow-up after 6 weeks.
Results
Between Oct 17th, 2019 to current, 15 patients were admitted to the stroke unit with MRI confirmed stroke. Ages ranged from 34 - 88 years (average age 66.5 years). 8 patients (60%) were female. Of those, 6 patients consented to being screened for OSA. Of these, 1 had 4%ODI >5/hr, and therefore received treatment with BIPAP. However, compliance was < 4 hrs on 2 consecutive nights.
Conclusion
This is ongoing QI project and results will be available after few more months of continued recruitment.
Support
Auto-adjusting BIPAP machines were provided by RESMED.

Abstract
AIMS Dietary pattern (DP) analysis has emerged as a holistic method to understand the effects of food intake on health outcomes. Though dietary intake has been associated with cardiovascular disease, the association of DPs and carotid intima-media thickness (CIMT), a robust early marker of cardiovascular disease progression has not been comprehensively investigated. This study systematically explores the association of a posteriori and a priori DPs and CIMT. DATA SYNTHESIS Through a systematic search of MEDLINE, CINAHL, and Web of Science, twenty studies that derived DPs using a posteriori or a priori methods with CIMT as an outcome were included. Four cross-sectional studies and 1 cohort paper reported a statistically significant association between increased consumption of 'unhealthy' foods (i.e processed meat, soda drinks and refined grain) and increased CIMT. While four cross-sectional studies reported a statistically significant association of DPs characterized by increased consumption of 'healthy' foods (i.e fruit and vegetables, fish) and decreased CIMT. DPs derived from each study varied depending on derivation method, study design and use of dietary data collection method. CONCLUSION Findings from this review are generally supportive of a trend between DPs with higher consumption of 'healthy' foods and lower consumption of 'unhealthy' foods and decreased CIMT; however, the association was largely not statistically significant. Evidence was overwhelmingly heterogeneous due to differences seen in DPs based on location and culture, sample characteristics and adjustment for confounders. Long-term prospective observational and interventional studies with standardized sample selection and dietary data collection are needed to significantly establish the role of DPs on CIMT.

Abstract
Abstract
Background
Direct oral anticoagulants (DOACs) are at least as effective as low-molecular weight heparins (LMWH) at preventing recurrence after cancer-associated venous thromboembolism (CA-VTE). DOACs are also oral and far less costly, but they may confer a higher bleeding risk than LMWH.
Purpose
To estimate the cost-effectiveness of DOACs and LMWHs for CA-VTE.
Methods
We developed a health state transition model to estimate recurrent VTE, bleeding events, quality-adjusted life years (QALY), and direct healthcare costs (2018 United States dollars) associated with DOACs vs. LMWH use. The model had four states: (1) long-term anticoagulation (first 3 months after VTE), (2) extended anticoagulation (more than 3 months after VTE), (3) off anticoagulants, and (4) death. We used a United States healthcare sector perspective, 3-month cycle length, and 1-year time horizon. Event probabilities were derived from the Hokusai Cancer VTE trial and other literature. Event and medication costs were obtained from national sources. We used a threshold of less than $50,000 per QALY gained to define cost-effectiveness.
Results
Compared to LMWH, DOACs were less costly (mean costs: $8,477 vs. $33,917 per year) and similarly effective (mean QALY: 0.616 vs. 0.622). The incremental cost-effectiveness ratio was $4,479,374 per QALY gained with LMWH, indicating that DOACs are cost-effective (Table 1). In threshold analyses, LMWH therapy only became cost-effective when DOAC recurrent VTE risk increased to at least 72% (relative risk vs. LMWH, 6.19) or DOAC clinically relevant bleeding increased to at least 39% (relative risk vs. LMWH, 10.09).

Uncertainty was derived from 1,000 stochastic model iterations. *Represents the minimum increased risk with DOAC that would result in LMWH achieving an ICER <$50K per QALY gained.
Conclusion
In this simulation study, DOACs were a cost-effective oral alternative to LMWH for the treatment of CA-VTE. For LMWH to be cost-effective, DOAC event rates needed to be far higher than what is likely to be observed in clinical practice.

Abstract
We describe the development and implementation of a compact, low power, infrared heated tube furnace for in situ powder X-ray diffraction experiments. Our silicon carbide (SiC) based furnace design exhibits outstanding thermal performance in terms of accuracy control and temperature ramping rates while simultaneously being easy to use, robust to abuse and, due to its small size and low power, producing minimal impact on surrounding equipment. Temperatures in air in excess of 1100 °C can be controlled at an accuracy of better than 1%, with temperature ramping rates up to 100 °C/s. The complete "add-in" device, minus power supply, fits in a cylindrical volume approximately 15 cm long and 6 cm in diameter and resides as close as 1 cm from other sensitive components of our experimental synchrotron endstation without adverse effects.

Abstract
Acute promyelocytic leukaemia (APML) is characterised by the t(15;17)(q22;q21), that results in the fusion of the promyelocytic leukaemia (PML) gene at 15q22 with the retinoic acid α-receptor (RARA) gene at 17q21. The current case report describes a 13-year-old male with APML, who was negative for PML/RARA fusion signal but reported to have an atypical translocation t(16;17). To the best of our knowledge this is the first case report of APML responsive to ATRA with such a translocation.

Abstract
In a cross-sectional study, prevalence of ovine herpesvirus 2 (family: Herpesviridae, subfamily: Gammaherpesvirinae, genus Macavirus and species: Ovine herpesvirus 2) infection was estimated in sheep population of Karnataka state in India. Based on the three stage cluster sampling method, whole blood samples (356) of sheep were collected from 11 sheep-dense districts of the state. The samples were tested for presence of OvHV-2 genome by recommended hemi-nested polymerase chain reaction (PCR) test. The true prevalence of OvHV-2 infection in sheep population of Karnataka was 24.44 %. Of the 11 district surveyed, highest true prevalence of 42.42 % (CI 25.56-59.29) was found in Raichur followed by Tumkur (39.02 %, CI 24.09-53.96). Inverse distance weighted interpolation of prevalence indicated that OvHV-2 prevalence within a given district is not uniform and there are areas of varied prevalence. The nucleotide sequence of the 422 bp DNA fragment, amplified in PCR, matched 99 % with OvHV-2 reference sequence and other sequences reported from India. Grouping of OvHV-2 sequences obtained from Karnataka with those from Andhra Pradesh, Tamil Nadu and Jammu and Kashmir in the neighbour joining tree indicated a close relationship among the OvHV-2s circulating in India. This is the first study in the country where systematic screening of sheep population of a state for the presence of OvHV-2 infection has been carried out, which indicated a widespread prevalence calling for an urgent need for policy measures to prevent economic losses due to the disease in susceptible cattle and buffalo species.

Abstract
Hilus cells are ovarian counterpart of testicular leydig cells seen at hilar region of ovary. We present an interesting case of hilus cell hyperplasia in fallopian tube associated with multiple leiomyomata of uterus in a postmenopausal woman. To our knowledge very few cases reported the existence of hilus cells outside the ovary. We received a specimen of hysterectomy with bilateral salpingooopherectomy. On gross examination both the tubes showed multiple small yellowish nodules. Microscopic examination showed aggregation of hilus cells beneath a normal tubal epithelium. Hilus cell hyperplasia was not seen in the ovaries. On immunohistochemistry, hilus cell showed positivity for vimentin and calretinin. Co-existence of hilus cell hyperplasia of fallopian tube and leiomyoma is very rare and may be subjected to further research.
