Abstract
Disparities in endometrial cancer has increased during the past decade with Black women more likely to be diagnosed at a later stage and have higher mortality. The majority of research has been focused on cultural barriers, socioeconomic status, lack of access to care, comorbidities, and tumor histology to explain these disparities. Limited studies have been conducted on the disparity in the treatment of endometrial intraepithelial neoplasia(EIN). We sought to analyze the differences in treatment used in the management of postmenopausal women with EIN to evaluate whether race/ethnicity is a contributing factor. An IRB approved retrospective study was conducted amongst women at a single institution diagnosed with EIN. Ethnicity/race was defined as non-Hispanic White, non-Hispanic Black, Hispanic, and Asian. Demographic and clinical data was extracted. Multivariable logistic regression was used to examine the association between ethnicity/race and treatment, adjusted for age, BMI, and underlying medical conditions such as cardiovascular disease and diabetes. In total, 254 patients were analyzed. A significant association between ethnicity/race and treatment with non-Hispanic Black women less likely to be treated with surgical management compared to non-Hispanic White women (OR = 0.326, 95 %CI 0.129-0.827, p = 0.026). Importantly, after adjusting for clinical risk factors(age, BMI, CVD, diabetes), non-Hispanic Black women remained at an increased risk of not undergoing surgical intervention (OR = 0.333, 95 % CI 0.125-0.882, p = 0.027). Future research is imperative to evaluate the root cause of this disparity in the healthcare system.

Abstract
BACKGROUND We hypothesized that postoperative Boston Carpal Tunnel Questionnaire (BCTQ) scores and ultrasound (US) measurements of the median nerve cross-sectional area (CSA) at the distal wrist crease are significantly decreased at 2-week, 6-week, and ≥ 6 months follow-up appointments, compared with baseline values. METHODS This study was a retrospective chart review of patients who presented to a single hand clinic with evidence of carpal tunnel syndrome over a 6-year period (2014-2020). Patients received baseline US measurements of the median nerve CSA as well as completion of the BCTQ, and for the patients who underwent carpal tunnel release (CTR), postoperative US measurements and questionnaire scores were obtained at 2 weeks, 6 weeks, or ≥ 6 months postoperatively. RESULTS This study included 224 separate wrists. Median Nerve CSA measurements were 13.2 ± 4.5 mm2 at baseline, 11.9 ± 3.6 mm2 at 2 weeks postoperatively, 11.6 ± 4.5 mm2 at 6 weeks postoperatively, and 11.7 ± 4.3 mm2 at 6 months or more (P = .002). The BCTQ Symptom Severity Scale scores were 3.14 ± 0.76 at baseline, 1.76 ± 0.63 at 2 weeks, 1.68 ± 0.70 at 6 weeks, and 1.41 ± 0.64 at 6 months or longer (P < .001). The BCTQ Functional Status Scale scores were 2.56 ± 0.89 at baseline, 2.03 ± .1.0 at 2 weeks, 1.65 ± 0.77 at 6 weeks, and 1.36 ± 0.61 at 6 months or longer (P < .001). CONCLUSIONS These findings demonstrated a sustained decrease in median nerve CSA and patient-reported outcomes following CTR at 2 weeks, 6 weeks, and between 6 and 12 months.

Abstract
BACKGROUND Left heart disease is the most common cause of pulmonary hypertension (PH) and is frequently accompanied by increases in pulmonary vascular resistance. However, the distinction between phenotypes of PH due to left heart disease with a normal or elevated pulmonary vascular resistance-isolated postcapillary PH (IpcPH) and combined pre- and postcapillary PH (CpcPH), respectively-has been incompletely defined using unbiased methods. METHODS AND RESULTS Patients with extremes of IpcPH versus CpcPH were identified from a single-center record of those who underwent right heart catheterization. Individuals with left ventricular ejection fraction <40% or with potential causes of PH beyond left heart disease were excluded. Medication usage in IpcPH and CpcPH was compared across Anatomical Therapeutic Chemical classes and identified vitamin K antagonists as the only medication with pharmacome-wide significance, being more commonly used in CpcPH and for an indication of atrial fibrillation in ≈90% of instances. Accordingly, atrial fibrillation prevalence was significantly higher in CpcPH in a phenome-wide analysis. Review of echocardiographic data most proximal to right heart catheterization revealed that left atrial diameter indexed to body surface area-known to be associated with atrial fibrillation-was increased in CpcPH regardless of the presence of atrial fibrillation. An independent cohort with serial right heart catheterizations and PH-left heart disease showed a significant positive correlation between change in left atrial diameter indexed to body surface area and change in pulmonary vascular resistance. CONCLUSIONS Guided by pharmacomic and phenomic screens in a rigorously phenotyped cohort, we identify a longitudinal association between left atrial diameter indexed to body surface area and pulmonary vascular resistance with implications for the future development of diagnostic, prognostic, and therapeutic tools.

Abstract
BACKGROUND While living in a socially disadvantaged neighborhood is linked with numerous health outcomes, its effect on patient-reported outcome scores and diagnostic measures in carpal tunnel syndrome (CTS) is not fully understood. This study examines the effect of neighborhood socioeconomic deprivation on CTS severity as measured by the Boston Carpal Tunnel Questionnaire (BCTQ), 6-item Carpal Tunnel Symptoms Scale (CTS-6), and diagnostic testing modalities. METHODS This was a retrospective analysis of patients who presented to the hand clinic at a single hospital system with symptoms consistent with CTS. Ultrasound cross-sectional area (CSA) of the median nerve, CTS-6, Symptom Severity Scale (SSS) and Functional Status Scale (FSS) of the BCTQ, and the Area Deprivation Index (ADI) national rank percentile were collected. Patients were grouped into 4 quartiles based on their ADI national percentile. Analyses of variance (ANOVAs) were conducted to test for statistical differences between the 4 quartiles based on the average values of median nerve CSA, CTS-6, SSS, and FSS score. The bottom quartile was compared with the upper 75% of the sample (26th-100th percentile) and to the upper quartile via Student t test. Statistical significance was set at P < .05. RESULTS Analyses of variance revealed no statistically significant differences between the 4 quartiles for either median nerve CSA, CTS-6, SSS, or FSS. When comparing the bottom quartile with the upper 75% of the sample and the upper quartile, no significant statistical differences were identified. CONCLUSIONS No relationships were found between social deprivation (ADI) and patient-reported outcomes, CTS-6 scores, or median nerve CSA.

Abstract
Streptococcus pneumoniae (SP) infections cause morbidity and mortality among children worldwide. Hence India introduced 13-valent pneumococcal conjugate vaccine (PCV-13) in 2017 in a phased manner. The primary objective of this study was to assess the proportion of healthy children having nasopharyngeal colonization (NP) with SP. Secondary objective was to determine prevalent serotype of SP among the PCV13 vaccinated and non-vaccinated children. This cross-sectional study was conducted in 4 hospitals of Lucknow District, Northern India. Three hundred healthy children (2-59 months) were recruited between July and August 2019 from vaccination-clinics of hospitals. NP specimen was cultured using 5% sheep blood agar plate containing gentamicin. Pneumococcal isolates were identified by optochin sensitivity and bile-solubility tests. Serotyping was done using Quellung Method. Of the 300 healthy children, 56.7% (170/300) were males and 59.3% (181/300) had received at least one dose of PCV13 vaccine. The NP carriage rate of SP among healthy children was 37.7% (113/300). Vaccine serotypes were found in 33.3% (22/66) in PCV vaccinated children and 48.9% (23/47) in non-vaccinated children (p 0.09). Common vaccine serotypes that isolated were: 18C, 19A, 19F, 23F, 3, 4, 6A, 6B, 9 V. Thus more than one-third of healthy children had NP colonization with SP. Adjusting for age, there was a trend for significant reduction in vaccine serotypes in the NP with one doses versus two or more doses (ptrend = 0.04).

Abstract
Abstract
Background
Invasive coronary angiography and non-invasive viability testing are the cornerstones of diagnosing and managing ischemic left ventricular dysfunction. At present there is no single test which serves both needs but, if developed, could revolutionise investigation of this condition. Coronary wave intensity analysis (cWIA) interrogates both contractility and microvascular physiology of the subtended myocardium [1,2] and therefore has the potential to fulfil this goal.
Objectives
We hypothesized that cWIA measured during coronary angiography would predict functional recovery with a similar accuracy to late gadolinium enhanced cardiac magnetic resonance imaging (LGE-CMR).
Methods
Patients with a left ventricular ejection fraction ≤40% and extensive coronary disease were enrolled. cWIA, fractional flow reserve and microvascular resistance were assessed with a simultaneous coronary Doppler and pressure-sensing guidewire during cardiac catheterization at rest, during hyperaemia and during low-dose dobutamine stress. Viability was assessed using LGE-CMR. Regional left ventricular function was assessed at baseline and 6-month follow up after optimization of medical therapy +/− revascularization, using transthoracic echocardiography. The primary outcome was regional functional recovery.
Results
Forty participants underwent baseline physiology, LGE-CMR and thirty had echocardiography at baseline and 6 months; 21/42 territories demonstrated functional recovery. Resting backward compression wave energy was significantly greater in recovering than non-recovering territories (−5240±3772 vs. −1873±1605 W m–2 s–1, p=0.099, Figure 1), and had comparable diagnostic accuracy to CMR (area under the curve 0.812 vs. 0.757, p=0.649, Figure 2); a threshold of −2500 W mm–2 s–1 had 86% sensitivity and 76% specificity at predicting recovery. Backward expansion wave energy did not predict recovery. FFR was numerically higher in recovering territories (0.81±0.17 vs. 0.71±0.16, p=0.058), whilst hyperaemic microvascular resistance did not differentiate recovering from non-recovering territories (1.97±0.73 vs. 2.29±1.00, p=0.287). The likelihood of functional recovery was similar in revascularised and non-revascularised territories (15/29 vs. 6/13 respectively, p=0.739). Low-dose dobutamine stress increased the energy of all waves, but did not improve the accuracy of cWIA in predicting recovery. In a regression model, resting backward compression wave energy and optimization of medical therapy predicted functional recovery; fractional flow reserve and hyperemic microvascular resistance did not.
Conclusions
Backward compression wave energy has similar accuracy to LGE-CMR in the prediction of functional recovery. cWIA has the potential to revolutionise the management of ischaemic left ventricular dysfunction, in a manner analogous to the effect of fractional flow reserve on the management of stable angina.

Abstract
Meningitis literally means inflammation of the meninges. It is mostly caused by bacteria, virus, fungus and protozoa and pyogenic meningitis constitutes a serious neurological disorder associated with significant morbidity and mortality in developing countries. This study was carried out to evaluate the clinical presentation and immediate outcome of pyogenic meningitis in children. This was a prospective observational study and conducted at department of Paeditrics in Cumilla Medical College Hospital, Cumilla, Bangladesh from July 2014 to June 2015. Total 50 children were diagnosed as pyogenic meningitis fulfilling the inclusion criteria was included in this study. Cases were enrolled purposively. Immediately after admission through history and clinical examination, complete blood count, random blood sugar, Cerebrospinal fluid (CSF) examination and blood culture was done in all patients. For statistical analysis chi-square test was done and significance of analysis was made when p value <0.05. This study includes patients aged between 2 months to 12 years and male female ratio was 1.5:1. Several risk factors like male sex (60.0%), age below one year (42.0%), Protein energy malnutrition (PEM) (30.0%), not exclusively breastfed (44.0%) were identified. Common presenting complaints were fever (100.0%), convulsion (96.0%), altered consciousness (42.0%) and vomiting (38.0%). Common physical signs were neck rigidity (56.0%), Kernig's sign (26.0%) and bulged fontanelle (34.0%). CSF was hazy in 54.0%, clear in 38.0% and turbid in 08.0% cases, CSF protein was more than 100mg/dl in 90.0% of the cases and glucose was less than 40mg/dl in most of the cases (94.0%). Streptococcus Pneumoniae (49.0%) followed by Neisseria Meningitidis (38.0%) were the two most commonly isolated organism responsible for pyogenic meningitis. Mortality rate during hospital stay was 18.0% and complications developed in 18.0% of cases. To avoid maltreatment in our resource limited setting due to failure of identifying organism, this study might help to administer appropriate antibiotics against organism and to reduce morbidity and mortality in meningitis. This study revealed less mortality rate in our country than neighbors and severe malnutrition important risk factors for the burden of pyogenic meningitis. It requires large scale multicentre studies to establish the whole scenario of Bangladesh.

Abstract
Clubroot disease caused by Plasmodiophora brassicae is one of the serious threats to canola (Brassica napus L. subsp. napus) production. The evolution of new pathotypes rendering available resistances ineffective compel the introgression of new resistance into canola and extend our understanding of the genetic and molecular basis of the resistance. In this paper, we report the genetic and molecular basis of clubroot resistance in canola, introgressed from a rutabaga (B. napus L. subsp. rapifera Metzg. 'Polycross'), by using a doubled-haploid (DH) mapping population. Whole-genome resequencing (WGRS)-based bulked segregant analysis followed by genetic mapping and expression analysis of the genes in resistant and susceptible DH lines at 7 and 14 d after inoculation were carried out. Following this approach, two major quantitative trait loci (QTL) located at 14.41-15.44 Mb of A03 and at 9.96-11.09 Mb of A08 chromosomes and their interaction was observed to confer resistance to pathotypes 3H, 3A, and 3D. Analysis of the genes from the two QTL regions suggested that decreased expression of sugar transporter genes (BnaA03g29290D and BnaA03g29310D) may play an important role in resistance conferred by the A03 QTL, while increased expression of the toll/interleukin-1 receptor (TIR)-nucleotide binding (NB)-leucine rich repeat (LRR) (TNL) genes (BnaA08g10100D, BnaA08g09220D, and BnaA08g10540D) could be the major determinant of the resistance conferred by the A08 QTL. Single-nucleotide polymorphism (SNP) allele-specific polymerase chain reaction (PCR)-based markers, which could be detected by agarose gel electrophoresis, were also developed from the two QTL regions for use in breeding including pyramiding of multiple clubroot resistance genes.

Abstract
Bacteroidetes and Firmicutes were most prevalent bacteria in the sheep rumen. Bacteroidetes were negatively correlated with the Euryarchaeota. Archaea constituted ∼2.5% of the ruminal microbiota. Methanobrevibacter gottschalkii constituted > 50% of the ruminal archaea. Hydrogenotrophic methanogens distribution leads to the variability in methane yield.
An in vivo study aiming to investigate the rumen methanogens community structure was conducted in Mandya sheep fed on straw and concentrate diet. The ruminal fluid samples were collected and processed for unravelling the rumen microbiota and methanogens diversity. Further, the daily enteric methane emission and methane yield was also quantified using the SF6 tracer technique. Results indicated that the Bacteroidetes (∼57%) and Firmicutes (25%) were two prominent affiliates of the bacterial community. Archaea represented about 2.5% of the ruminal microbiota. Methanobacteriales affiliated methanogens were the most prevalent in sheep rumen. The study inveterate that the ruminal archaea community in sheep is composed of 9 genera and 18 species. Methanobrevibacter represented the largest genus of the archaeome, while methylotrophs genera constituted only 13% of the community. Methanobrevibacter gottschalkii was the prominent methanogen, and Methaobrevibacter ruminantium distributed at a lower frequency (∼2.5%). Among Methanomassiliicoccales, Group 12 sp. ISO4-H5 constituted the most considerable fraction (∼11%). KEGG reference pathway for methane metabolism indicated the formation of methane through hydrogenotrophic and methylotrophic pathways, whereas the acetoclastic pathway was not functional in sheep. The enteric methane emission and methane yield was 19.7 g/d and 20.8 g/kg DMI, respectively. Various species of Methanobrevibacter were differently correlated, and the distribution of hydrogenotrophic methanogens mainly explained the variability in methane yield between the individual sheep. It can be inferred from the study that the hydrogenotrophic methanogens dominate the rumen archaeal community in sheep and methylotrophic/aceticlastic methanogens represent a minor fraction of the community. Further studies are warranted for establishing the metabolic association between the prevalent hydrogenotrophs and methylotrophs to identify the key reaction for reducing methane emission.

Abstract
Ocular tuberculosis is an extra-pulmonary form of systemic Tuberculosis (TB). It is rarely found concomitant with active pulmonary tuberculosis (PTB). The aim of this prospective observational study was to evaluate the pattern of tubercular uveitis (TBU) in the patients with active PTB who attended in our Uvea clinic at NIO&H from July 2018 to December 2020. Active PTB patients who had uveitis consistent with TBU and TBU patients who were confirmed as active lung lesion were included in the study. Chest X-ray, TST, IGRA (QuantiFERON-TB Gold Test), RT PCR of aqueous fluid for tubercular bacillus, Gene Xpert TB test of sputum were done to confirm the diagnosis of ocular and primary TB. If the induration is 15 mm of TST was considered patient in this study. Among 33 patients of active PTB, 4 had TBU (12.12%). Among 48 patients of TBU, 5 had active PTB (10.41%). 13 eyes of 9 patients were affected. Mean age at presentation was 41.8 years. There were anterior uveitis in 23.00% eyes, posterior uveitis in 69% eyes and panuveitis in 7.00% eyes. Choroidal granuloma was the most common presentation of posterior uveitis (46.00%). There were more than 4 times chance to develop choroidal granuloma in patients with active PTB than extrapulmonary TB (Χ²=4.53, <0.05), TBU patients with choroidal granuloma should be evaluated meticulously for active PTB and active PTB patients should be evaluated routinely by ophthalmologist for the search of TBU.

Abstract
Neutrophil Gelatinase-Associated Lipocalin (NGAL) is rapidly released by renal tubules after injury, potentially allowing early identification of acute kidney injury (AKI) after cardiac surgery. However, the diagnostic performance of NGAL has varied widely in clinical studies and it remains unknown what factors modify the relationship between NGAL and AKI. The main objective of the study was to determine the efficacy of NGAL in early detection of AKI among the CABG patients undergoing cardiopulmonary bypass (CPB). This prospective observational study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh in collaboration with the Department of Biochemistry, BSMMU among 42 patients admitted into the Department of Cardiac Surgery, Ibrahim Cardiac Hospital and Research Institute, Dhaka Bangladesh from July 2014 to June 2015. For the measurement of NGAL, urine samples were obtained before surgery and 6 hours after commencement of CPB. Serum creatinine was measured preoperatively and 6, 24 and 48 hours postoperatively. Increase in the serum creatinine level at 6, 24 and 48 hours after surgery was used to analyze the diagnostic value of urinary NGAL. In this study 42 CABG patients with no known renal insufficiency planned to have CPB were included. Receiver-operator characteristic (ROC) was constructed by using NGAL, which gave a cut off value of ≥185.90ng/ml. Eight patients were AKI positive among them 6(75.0%) patients were NGAL positive and 2(25.0%) were NGAL negative. Diagnosis of AKI was delayed by 24-48 hours by serum creatinine measurement. This study has demonstrated that level of urinary NGAL concentration at 6 hours post CPB increased before the increase of serum creatinine level and NGAL is an early predictor of AKI in adult cardiac surgical patients. The early detection of renal injury by NGAL may allow earlier intervention in patients with high risk for AKI.

Abstract
An in vivo study was conducted to compare the enteric methane emissions and diversity of ruminal methanogens in cattle and buffaloes kept in the same environment and fed on the same diet. Six cattle and six buffaloes were fed on a similar diet comprising Napier (Pennisetum purpureum) green grass and concentrate in 70:30. After 90 days of feeding, the daily enteric methane emissions were quantified by using the SF6 technique and ruminal fluid samples from animals were collected for the diversity analysis. The daily enteric methane emissions were significantly greater in cattle as compared to buffaloes; however, methane yields were not different between the two species. Methanogens were ranked at different taxonomic levels against the Rumen and Intestinal Methanogen-Database. The archaeal communities in both host species were dominated by the phylum Euryarchaeota; however, Crenarchaeota represented <1% of the total archaea. Methanogens affiliated with Methanobacteriales were most prominent and their proportion did not differ between the two hosts. Methanomicrobiales and Methanomassillicoccales constituted the second largest group of methanogens in cattle and buffaloes, respectively. Methanocellales (Methanocella arvoryza) were exclusively detected in the buffaloes. At the species level, Methanobrevibacter gottschalkii had the highest abundance (55-57%) in both the host species. The relative abundance of Methanobrevibacter wolinii between the two hosts differed significantly. Methanosarcinales, the acetoclastic methanogens were significantly greater in cattle than the buffaloes. It is concluded that the ruminal methane yield in cattle and buffaloes fed on the same diet did not differ. With the diet used in this study, there was a limited influence (<3.5%) of the host on the structure of the ruminal archaea community at the species level. Therefore, the methane mitigation strategies developed in either of the hosts should be effective in the other. Further studies are warranted to reveal the conjunctive effect of diet and geographical locations with the host on ruminal archaea community composition.

Abstract
Abstract
Introduction
Total knee and hip arthroplasty significantly improve quality of life in people suffering from end-stage hip & knee arthritides. Enhanced recovery programs have shown improved outcomes following elective arthroplasty by decreasing patients anxiety, postoperative pain and reducing the length of hospital stay (LOS). The aim of our study is to evaluate the impact of preoperative education programs on length of hospital stay in patients undergoing hip & knee arthroplasty.
Method
Retrospective data was collected from a consecutive series of 520 patients' charts and Irish National Orthopedic Register (INOR) who underwent Hip or Knee arthroplasty from January 1, 2018, to December 31, 2018, in Our Lady Hospital, Navan. The length of stay study compared two hundred and twenty-six patients in the Educational Group (EG) who attended the Hip & Knee School (Preoperative Education Class) with 294 patients in the Conventional Group (CG) who did not attend the hip and knee educational programme.
Result
We identified that Length of Hospital Stay decreased to 5.2 days in Educational Group from 5.5 days in Conventional Group (P-value equals to 0.26, statistically insignificant, t = 1.1093 df = 518), with a mean difference of only 0.3 days (95% confidence interval).
Conclusion
Preoperative education does not reduce the length of hospital stay in primary hip & knee arthroplasty.
Take-home message
Preoperative education has no role in reducing hospital stay in Arthroplasty patients.

Abstract
Abstract
Background
Performing a minimum number of colonoscopies annually has been proposed by some jurisdictions as a requirement for maintaining privileges. However, this practice is supported by limited evidence.
Aims
The objective of this study was to determine if annual colonoscopy volume was associated with colonoscopy quality metrics.
Methods
A population-based study was performed using the Southwest Ontario Colonoscopy cohort, which consists of all adult patients who underwent colonoscopy between April 2017 and Oct 2018 at 21 academic and community hospitals within the health region. Data were collected through a mandatory quality assurance form completed after each procedure and pathology reports were manually reviewed. Physician annualized colonoscopy volumes were compared by correlation analysis to each quality-related outcome, by means of the area under the receiver operating characteristics curve (AUROC), and logistic regression. The prognostic value of colonoscopy volume was also adjusted for case-mix and potential confounders in separate regression analyses for each outcome. The primary outcome was ADR. Secondary outcomes were polyp detection rate (PDR), sessile serrated polyp detection rate (SSPDR), and cecal intubation.
Results
A total of 47,195 colonoscopies were performed by 75 physicians (37.5% by gastroenterologists, 60% by general surgeons, 2.5% others). There were no clear relationships between annual colonoscopy volumes and study outcomes. Colonoscopy volume was not associated with ADR (OR 1.03, 95% CI 0.96–1.10, p=0.48) and corresponded to an AUROC not significantly different from the null (AUROC 0.52, 95% CI 0.43–0.61, p=0.65). Multi-variable regression adjusting for case-mix also demonstrated no predictive value of annual colonoscopy volume for the primary outcome (OR 1.03, 95% CI 0.94–1.12, p=0.55). Similarly, analyses of secondary outcomes failed to find an association between colonoscopy volume and PDR, SSPDR, or cecal intubation (Table 1).
Conclusions
Annual colonoscopy volumes do not predict ADR, PDR, SSPDR, or cecal intubation rate.
Results of unconditional and conditional approaches for examining the predictive value of annual colonoscopy volume for quality related outcomes.

Abstract
The perishable herb ginger (Zingiber officinale) possesses natural aroma and different
biologically active components which are beneficial for our health. This can be dried for
preservation in pick season for shelf-life increment. This study studied the analysis of the
chemical composition, moisture sorption isotherm, dehydration kinetics of ginger for
preservation. Air drying was carried out using a cabinet dryer at different temperatures
and thickness. According to the sorption isotherm study, monolayer moisture content
(MMC) is higher as per Guggenheim-Anderson-DeBoer (GAB) equation compared to the
Brunauer-Emmett-Teller (BET) equation. Drying rate increased with the increase in
temperature at constant thickness while the adverse result was found with the increase in
thickness at a constant temperature. Then, powder-based drinks were prepared by using
five different percentages of ginger. The preferences of consumers were measured by
statistical analysis of the scores obtained from the response of organoleptic taste panel.
The sample containing 1.84% ginger powder was considered the best in overall
acceptability

Abstract
Free flap reconstruction after surgical ablation of head & neck cancer greatly improve the surgical outcome. Microvascular anastomosis is an important part of Microsurgery and it is not widely practiced in every center. A retrospective review was conducted in the Head & Neck Division of Otolaryngology-Head & Neck Surgery Department, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from May 2016 to June 2017. Total 20 patients with head & neck cancer had been treated surgically between this period and 14 patients were reconstructed with free flap. The focus of this study is to establish the surgical outcome, which is more with free flap reconstruction in the patients previously diagnosed as head & neck cancer. We reconstructed 14 cases of oral cavity carcinoma (Stage IV) with the free flap. Majority cases were carcinoma involving the buccal mucosa with retromolar trigone (36%) followed by buccal mucosa (22%), buccal mucosa with lower alveolus (21%), carcinoma tongue with floor of the mouth (14%) and floor of the mouth (7%). Radial forearm freflap (RFFF) were commonly used in 10 cases (71.4%) and Anterolateral thigh flap (ALT) used in four cases (21.5%). Partial flap loss was seen in one case and wound infection occurred in another case but both were managed successfully with postoperative dressing and debridement. Microvascular free flap reconstruction can be a good choice after surgical removal of the head & neck cancer diseases and it should be practiced in every well-equipped tertiary medical center with the help of properly trained surgeon.
