Abstract
Biosimilars are known to be pharmaceutical products which are very similar to a biologic drug. FKB327 is one such biosimilar of the drug Adalimumab which is prescribed in treating autoimmune diseases like Rheumatoid Arthritis. The aim of this review is to evaluate the efficacy, immunogenicity and safety of the drug FKB327 in treating patients with mild to moderate Rheumatoid Arthritis and compare the same with that of the drug Adalimumab. Two databases (PubMed and Cochrane Library) were used to screen relevant publications using pre-determined inclusion and exclusion criteria. Of the 12 studies found to be relevant, 3 were found to be eligible for the review. The data were extracted for the study characteristics, outcome measures, complications, and safety. The quality of the papers was assessed through Jadad scoring. Three (3) papers were reviewed in the study although there were limitations in reviewing efficacy as one of the papers lacked required data for efficacy. Efficacy was observed through ACR20 response and DAS28 score in the 24th week of all the three studies and immunogenicity was reviewed through the presence of Anti-drug antibody in patients after administration of both the drugs in same dosage. Safety was assessed through the development of complications after the administration of the drugs. The review concludes that there are similarities in efficacy, immunogenicity and safety between FKB327 but could not adequately prove the superiority of FKB327 over Adalimumab.

Abstract
Manufacture of chimeric antigen receptor (CAR)-T cells usually involves the use of viral delivery systems to achieve high transgene expression. However, it can be costly and may result in random integration of the CAR into the genome, creating several disadvantages including variation in transgene expression, functional gene silencing and potential oncogenic transformation. Here, we optimized the method of nonviral, CRISPR/Cas9 genome editing using large donor DNA delivery, knocked-in an anti-tumor single chain variable fragment (scFv) into the N-terminus of CD3ε and efficiently generated fusion protein (FP) T cells. These cells displayed FP integration within the TCR/CD3 complex, lower variability in gene expression compared to CAR-T cells and good cell expansion after transfection. CD3ε FP T cells were predominantly CD8+ effector memory T cells, and exhibited anti-tumor activity in vitro and in vivo. Dual targeting FP T cells were also generated through the incorporation of scFvs into other CD3 subunits and CD28. Compared to viral-based methods, this method serves as an alternative and versatile way of generating T cells with tumor-targeting receptors for cancer immunotherapy.

Abstract
This study aims to find out the difference in mortality rates between vaccinated & non-vaccinated Covid-19 positive patients who were admitted in a tertiary centre (Ward and Intensive care unit) of Bangladesh. Retrospective analysis of data over 6 weeks in February 2022- March 2022, 100 confirmed Covid-19 positive patients were included- 50 patients from ICU and 50 patients from ward irrespective of age, gender, vaccination status and co-morbidities. Seventy five percent (75.0%) of all confirmed Covid-19 positive patients were vaccinated. Mortality among vaccinated people was less compared to non-vaccinated population 41.3% vs. 52%. Interestingly it was found pregnancy was the most significant risk factor in childbearing age female group- 86.7% of patients (pregnant and peripartum) required Intensive care admission and mortality was 40.0% although none of them had any recorded co-morbidities. Again, mortality among vaccinated was significantly less (35.7%) compared to 100.0% mortality among unvaccinated. Mortality rate among patient admitted in intensive care was significantly high compared to patients treated in ward- 72.0% vs. 16.0%. In ICU 83.0% of patients who died were vaccinated (90.0% had 2 doses and 10.0% had 3 doses). On the other hand, 87.5% who died in ward were unvaccinated. Among the survivors from intensive care units- 93.0% were vaccinated compared to 7.0% unvaccinated. Pre-existing co-morbidities increased mortality (59.0%) compared to 40.9% mortality in patients without any previous medical conditions. We found vaccination against Covid-19 reduces the rate of death irrespective of co-morbidities or severity of disease. Recovery rate was significantly increased in vaccinated patients requiring intensive care support. Pregnancy was found to be the most important risk factor for Intensive care admission and mortality in otherwise healthy childbearing age females and mortality was significantly high (100.0% though limited data availability) in unvaccinated. These results require further revalidation on larger population.

Abstract
Fixed drug eruption (FDE) is a distinctive pattern of cutaneous adverse drug reaction. Characteristically the eruption recurs at the same site on re exposure to the offending agent. Aim of this study was to evaluate and identification of the various offending drugs causing FDE which may help the physician to limit the associate complication regarding the drug. This observational cross sectional study was conducted from 1st June 2021 to 31st May 2022 in the department of Dermatology & Venereology of Mymensingh Medical College Hospital after taking approval from institutional ethical committee. A detailed history with clinical evaluation were done for all patients with FDE and thereby recorded in a pre designed proforma. Analysis of data was done using Microsoft Excel 2010 Spread sheet. Out of 65 cases 36(55.38%) were male and 29(44.6%) were female. Majority of cases were found in the age group of 31 to 40 years. The most common group of drug causing FDE was NSAID (52.31%) followed by antimicrobials (44.61%) and anti epileptics (3.07%). Ibuprofen (20.0%) was the most common offending drug followed by doxycycline (18.46%), diclofenac and fluconazole (13.84%), naproxen (9.23%), ciprofloxacin (7.69%), paracetamol (6.15%), metronidazole (4.61%), carbamazepine (3.07%) and aspirin (3.07%) respectively. Extremities (43.07%) were the most frequently involved site followed by trunk (29.23%) and face (10.77%). Generalized FDE found in 16.92% cases. Although FDE are very common the offending drugs show some regional variation as a result of changing trends of pharmacotherapy.

Abstract
Abstract
With the mental wellbeing of billions of people at risk due to climate change, more research is required to better understand mental health and psychological implications of climate vulnerability. This research contributes to understanding how people in climate vulnerable populations psychologically cope with stress with crucial implications for adaptation efforts. We conducted n = 60 qualitative in-depth interviews with men and women in Bhola, Bangladesh to elicit the lived experiences of a climate vulnerable population. We analysed data following the tenets of Grounded Theory. Through our inductive analysis, we found coping strategies where participants highlighted what they did when encountering stress, such as ‘Resignation’ or ‘Help Seeking'. Barriers to coping were, among others, limited ‘Efficacy', ‘Time’ or ‘Stigma'. We categorized coping strategies with barriers as high-barrier coping strategies and, those without reported barriers, as low- barrier coping strategies. High-barriers restricted participants - especially women - in their coping efforts and led them to using low-barrier coping strategies. Some low-barrier coping strategies can be interpreted as maladaptive if used frequently, as they are unhealthy and draw upon resources needed to adapt for the future. Maladaptive coping strategies can thus impede long-term adaptation by reducing motivation and the ability and willingness to act. To enable adaptive coping, we recommend lifting the barriers to coping through community-led interventions where community workers create platforms for sharing problems and knowledge, such as group support meetings. Sharing and discussing could strengthen efficacy and open new opportunities for functional, adaptive coping. As the negative impacts of climate change will be felt globally with more intensity and frequency, enabling adaptive coping and removing barriers to coping in frontline communities will be essential to supporting physical and mental wellbeing.
Key messages
• Barriers to adaptive coping strategies can lead people to using maladaptive low-barrier coping strategies, which draw upon resources needed for long-term adaptation.
• Enabling adaptive coping by lifting barriers to coping in climate vulnerable populations is crucial to strengthen adaptation efforts.

Abstract
Abstract
The routine use of prophylactic antibiotics for the prevention of surgical site infection is no longer recommended in all types of elective ventral hernia repairs, according to national and international guidelines.NICE recommends that prophylactic antibiotics are given only in clean surgeries that involve the use of a prothesis or implant. The British Hernia Society and European Hernia Society state that there is no indication for antibiotic prophylaxis in both open and laparoscopic elective groin hernia repairs with mesh in patients that are healthy and considered low risk for surgical site infection.
This is a retrospective audit of patients who underwent elective ventral hernia repairs at Ealing Hospital between June 2021 and December 2021 to assess the compliance of antibiotic prophylaxis with the current guidelines.
Forty-nine patients underwent elective ventral hernia repair, of which 44 was with the use of a mesh.Thirty-five of these cases (79.5%) received prophylactic antibiotics. All cases that underwent laparoscopic hernia repair received prophylactic antibiotics. Five cases underwent an elective open ventral hernia repair without a mesh.Three cases who were considered low risk received prophylactic antibiotics.
In conclusion, majority of patients along with those who were considered high risk received prophylactic antibiotics, which is compliant with guidelines. However, patients who did not have a mesh repair, or were not considered high risk also received prophylactic antibiotics.It would be useful to improve the awareness of the guidelines by creating clear local guidelines and improving documentation of reasons to give antibiotics against the recommendations.

Abstract
Abstract
Tuberculosis (TB) is a very rare cause of biliary stricture that is difficult to diagnose and usually requires surgical intervention in order to rule out underlying malignant etiology. A 28-years old woman with obstructive jaundice, who was originally thought to have cholangio-carcinoma. Diagnosis of tuberculosis was made on PCR testing of bile. Patient was started on antitubercular treatment, and she responded well. This case presented a rare case of common bile duct stricture due to biliary tuberculosis. This is an important condition to diagnose because early recognition with prompt treatment results in complete resolution. Even though biliary tuberculosis is a rare cause of obstructive jaundice, in endemic areas, it should be considered as a differential diagnosis and investigated, as it can be potentially curable.

Abstract
Aim
To reaudit the practice of definitive management of gall stones pancreatitis in our trust for the period of 1st May-31st October and compare the result with previous one (1st June 2019–31st Dec 2019).
Method
It was a retrospective collection of data of patients admitted to our trust with biliary pancreatitis. Electronic notes, PACS for US report, Electronic discharge summary and Operative notes analysed.
Results
We identified 4 patients admitted with biliary pancreatitis during the re-audit period. US report was checked for confirmation of diagnosis of gall stones. The EDN was checked for date for Laparoscopic cholecystectomy. Unfortunately, none of them had their procedure time in 2 weeks’ time of their diagnosis. The reason behind this was because of COVID-19 pandemic, we were backlogging with our elective list. All the patients eventually underwent their procedure, but not in 2 weeks’ time as per the guidelines. All suitable patients had their cholecystectomy in a timely manner during first audit. None had it in timely manner during second audit.
Conclusions
Early Laparoscopic cholecystectomy for simple gallstone pancreatitis prevents life threatening Pancreatitis and readmissions.
The UK guidelines on management of pancreatitis issued by British society guidelines (BSG) states that all mild gall stones pancreatitis should have definitive management of lithiasis on the same admission or within 2 weeks (Recommendation B). In our practice, all our suitable patients during first audit had timely Laparoscopic cholecystectomy, however, no one had it in timely manner on the next audit for COVID-19 pandemic.

Abstract
Abstract
Aim
NICE Clinical Guidelines (CG138) specify the importance of involvement of family members and carers at key patient care junctures. Furthermore, published literature and our own experience reaffirm that ‘low-quality communication causes profound distress to families that can affect the quality of dying and bereavement'. There is little evidence on NOK’s experience for surgical patients, so we sought to assess whether NOK details were available and whether they had been contacted peri-operatively for patients receiving laparotomies.
Method
We performed a closed loop audit using NELA database to identify patients admitted for laparotomies between February 1st to July 31st, 2021. The initial data was collated, analysed, and presented during educational meetings with informal reminders for a week to implement changes. Thereafter, data was collected to complete the audit cycle on communication with NOK.
Results
A total of 70 patients were included. Prior to the implementation, 86% of patients undergoing laparotomies had NOK information documented in clinical records, with only 75% of telephone numbers reachable and 33% had documented evidence of contact within 48 hours post-operation. Post-implementation, 97% of patients had their NOK information in their clinical records, with 97% telephone numbers reachable and 41% had documented evidence of contact with 48hours.
Conclusions
The importance of clerical staff and clerking doctors establishing NOK’s details, documenting these within iCare/notes and establishing whether patient are happy with NOK being contacted for updates on patient management, could reduce distress and potentially improve the experiences of hospital admission, recovery and in some cases, bereavement.

Abstract
A study was conducted in Dhubri and Biswanath Chariali Municipality areas to assess the adoption of hygienic and sanitation practices being followed by poultry butchers. A total of 60 poultry butchers were selected randomly, 30 from each Municipality area so that the final sample consisted of 60 poultry butchers. Data were collected using a pre-tested structured interview schedule by personal interviews. The schedule was designed to collect information on the socioeconomic profile of the butchers, personal and meat shop hygiene, maintenance of meat shop and its equipment. The data revealed that all the poultry butchers were male among which (75%) of them had an education level only up to eight standard. The overall mean age of the poultry butchers was found to be 39.95±8.64 years of which majority (75%) of them belong to middle age group. The present study indicated that none of the poultry butchers underwent any formal training for hygienic meat handling. It was also pointed out that most (85%) of the butcheries were located at market area, while only a few (15%) were found in the residential area. Only 18.33 per cent of the poultry butchers wore clean clothes while 81.67 per cent of them did not adopt this practice during working. Majority (88.33%) of them did not wash their hands after smoking/ chewing tobacco.It was also revealed that majority (88.33%) of the butchers did not clean knives before and after cutting of meat. Majority of the butchers agreed that cleanliness of equipment (71.67%), the meat shop and its surrounding (68.33%) and personal hygiene (68.33%) were some of the important factors that were essential to ensure wholesome meat production. From the above study, it may be concluded that appropriate interventional measures by the concerned agencies such as awareness trainings for poultry butchers on crucial areas of food safety, hygienic practices relating to meat handling and personal safety are imperative. The results of the study also shed light on the need for measures to improve the infrastructural facilities in poultry meat butcheries and for appropriate interventions to strengthen the food quality control system by the government regulatory authorities.

Abstract
Abstract
Background
IPT a benign lesion seldom encountered in clinical practice. It’s mysterious in origin & remains ambiguous.Infection, stone,autoimmune disease,systemic inflammatory response,trauma,foreign body and neoplasm attributes to etiological factors.Advanced imaging modalities help in increased detection of focal liver lesion.
Aim
To analyze its clinical significance. 33 patients with focal liver lesions were evaluated and treated surgically as hepatic neoplasm consecutively from July 2013 to January 2020.
Method
Retrospective observational cohort study.
Results
14 male & 19 female were studied, mostly in 3rd decade of life. Clinically only 21% of them presented with fever.In 24 patients the lesions were located in left lobe of liver.The operative procedures were: wedge resection in 3 patients,limited resection in 5 patients,Left Hepatectomy 7 patients,Left lateral hepatic segmentectomy in 17 patients, right hepatectomy in 2 patients & central hepatectomy in 1 patient. 8patients required bilioenteric anastomosis as additional procedure.Histopathological study revealed Tuberculosis in 7 patients(21.21%),fungal granuloma in 3 patients, foreign body granuloma in 3 patients, Ductal calculi with abscess in 9 patients and idiopathic in 7 patients.
Conclusions
IPT of liver represents a rare entity usually mistaken as malignant lesion.Despite the low prevalence, it often creates a diagnostic dilemma resulting into therapeutic uncertainty.

Abstract
Abstract
Objective
The objective of this study is to compare the frequency of inguinodynia in ilioinguinal neurectomy VS no neurectomy in patients undergoing Lichtenstein mesh hernioplasty.
Method
200 male patients with unilateral, primary, reducible inguinal hernia were randomly distributed in to two groups by using lottery method to undergo Lichtenstein’s hernia repair i.e., with and without ilioinguinal neurectomy. All the operation were carried out under local anesthesia. Pain score was calculated using the VAS system at 3rd month and inguinodynia was labelled if it is more than 1 on VAS scale.
Results
200 male patients with mean age of 53.25 ± 6.768 were included. 42 (21%) had Inguinodynia after surgery. When we cross tabulated both groups with inguinodynia, results came up significant (p = 0.001). In neurectomy group 10 patients had inguinodynia while in no neurectomy group, 32 patients were having Inguinodynia. There was no effect of malnutrition on outcome. Younger age group benefitted more from procedure.
Conclusions
It is concluded that there is difference in frequency of inguinodynia in ilioinguinal neurectomy versus no neurectomy in patients undergoing Lichtenstein hernia repair. Patients with ilioinguinal neurectomy had reduced incidence of inguinodynia.

Abstract
Abstract
Metastasis pattern of prostate cancer varies widely; however, predominant affinity is towards regional lymph nodes. Mediastinal lymphadenopathy as the initial presentation, in absence of any pelvic lymph node involvement, remains extremely rare. Most patients are incidentally diagnosed and often have widespread metastatic disease on confirmation of diagnosis. A high index of clinical suspicion is necessary and routine clinical examination such as a digital rectal examination (DRE) can aid in earlier diagnosis and prompt clinical intervention can improve disease outcome. We present this case study of a 53-year-old patient who was incidentally diagnosed with metastatic adenocarcinoma of prostatic origin by TBUS-EBNA of hilar lymph nodes in the absence of pelvic lymphadenopathy.

Abstract
Natural killer (NK) cells are potent innate immune system effector lymphocytes armed with multiple mechanisms for killing cancer cells. Given the dynamic roles of NK cells in tumor surveillance, they are fast becoming a next-generation tool for adoptive immunotherapy. Many strategies are being employed to increase their number and improve their ability to overcome cancer resistance and the immunosuppressive tumor microenvironment. These include the use of cytokines and synthetic compounds to bolster propagation and killing capacity, targeting immune-function checkpoints, addition of chimeric antigen receptors (CARs) to provide cancer specificity and genetic ablation of inhibitory molecules. The next generation of NK cell products will ideally be readily available as an “off-the-shelf” product and stem cell derived to enable potentially unlimited supply. However, several considerations regarding NK cell source, genetic modification and scale up first need addressing. Understanding NK cell biology and interaction within specific tumor contexts will help identify necessary NK cell modifications and relevant choice of NK cell source. Further enhancement of manufacturing processes will allow for off-the-shelf NK cell immunotherapies to become key components of multifaceted therapeutic strategies for cancer.

Abstract
This prospective study was done to determine fetomaternal outcomes of pregnancy in women with Tetralogy of Fallot (TOF) and carried out in two centres especially in the care of patients with adult congenital heart disease (CHD) from January 2005 to December 2009. Clinical, haemodynamic and obstetric data were reviewed for pregnant women with TOF. Ten (10) pregnant women were identified in the age range 18 to 47 years. Most of the patients were in the age group of 18 to 27 years, 34 to 36 weeks gestational age (in week) and primi gravida (60%). Right-sided aortic arch (20%) and major anomalies of pulmonary collaterals (30%) were common anomalies anatomical association. Normal vaginal delivery was the mode of delivery (70%) in the majority of the patients. Spontaneous abortions were occurred in 3(30%) patients. Primary maternal cardiac events complicating pregnancies were congestive heart failure (20%), arrhythmias and cardiovascular events (10%). Premature labor (40%) was the most common obstetric complication. Premature birth (40%), fetal demise (20%), neonatal death (10%) and cardiac anomaly at birth (10%) were the offspring complications in the study. Women with TOF can go through pregnancy with a low risk to themselves with frequent treatable complications, but there is a high incidence of miscarriage, premature births and low birth weight. An incidence of congenital anomaly in the fetus is higher than that found in the normal population.

Abstract
Information about genetic diversity and population structure among goat breeds is essential for genetic improvement, understanding of environmental adaptation as well as utilization and conservation of goat breeds. Here, we measured genetic diversity and population structure in multiple Chinese goat populations, namely, Nanjiang, Qinggeda, Arbas Cashmere, Jining Grey, Luoping Yellow and Guangfeng goats. A total of 193 individuals were genotyped for about 47 401 autosomal single nucleotide polymorphisms (SNPs). We found a high proportion of informative SNPs, ranging from 69.5% in the Luoping Yellow to 93.9% in the Jining Grey goat breeds with an average mean of 84.7%. Diversity, as measured by expected heterozygosity, ranged from 0.371 in Luoping Yellow to 0.405 in Jining Grey goat populations. The average estimated pair-wise genetic differentiation (FST ) among the populations was 8.6%, ranging from 0.2% to 16% and indicating low to moderate genetic differentiation. Principal component analysis, genetic structure and phylogenetic tree analysis revealed a clustering of six Chinese goat populations according to geographic distribution. The results from this study can contribute valuable genetic information and can properly assist with within-breed diversity, which provides a good opportunity for sustainable utilization of and maintenance of genetic resource improvements in the Chinese goat populations.

Abstract
STUDY QUESTION What are the in vivo and in vitro actions of kisspeptin-54 on the expression of genes involved in ovarian reproductive function, steroidogenesis and ovarian hyperstimulation syndrome (OHSS) in granulosa lutein (GL) cells when compared with traditional triggers of oocyte maturation? SUMMARY ANSWER The use of kisspeptin-54 as an oocyte maturation trigger augmented expression of genes involved in ovarian steroidogenesis in human GL cells including, FSH receptor (FSHR), LH/hCG receptor (LHCGR), steroid acute regulatory protein (STAR), aromatase, estrogen receptors alpha and beta (ESR1, ESR2), 3-beta-hydroxysteroid dehydrogenase type 2 (3BHSD2) and inhibin A (INHBA), when compared to traditional maturation triggers, but did not alter markers of OHSS. WHAT IS KNOWN ALREADY hCG is the most widely used trigger of oocyte maturation, but is associated with an increased risk of OHSS. The use of GnRH agonists to trigger oocyte maturation is a safer alternative to hCG. More recently, kisspeptin-54 has emerged as a novel therapeutic option that safely triggers oocyte maturation even in women at high risk of OHSS. Kisspeptin indirectly stimulates gonadotropin secretion by acting on hypothalamic GnRH neurons. Kisspeptin and its receptor are also expressed in the human ovary, but there is limited data on the direct action of kisspeptin on the ovary. STUDY DESIGN SIZE, DURATION Forty-eight women undergoing IVF treatment for infertility consented to kisspeptin-54 triggering and/or granulosa cell collection and were included in the study. Twelve women received hCG, 12 received GnRH agonist and 24 received kisspeptin-54 to trigger oocyte maturation. In the kisspeptin-54 group, 12 received one injection of kisseptin-54 (9.6 nmol/kg) and 12 received two injections of kisspeptin-54 at a 10 h interval (9.6 nmol/kg × 2). PARTICIPANTS/MATERIALS, SETTING, METHODS Follicular fluid was aspirated and pooled from follicles during the retrieval of oocytes for IVF/ICSI. GL cells were isolated and either RNA extracted immediately or cultured in vitro ± kisspeptin or hCG. MAIN RESULTS AND THE ROLE OF CHANCE GL cells from women who had received kisspeptin-54 had a 14-fold and 8-fold higher gene expression of FSHR and a 2-fold (ns) and 2.5-fold (P < 0.05) higher expression of LHCGR than GL cells from women who had received hCG or GnRH agonist, respectively. CYP19A1 expression was 3.6-fold (P < 0.05) and 4.5-fold (P < 0.05) higher, STAR expression was 3.4-fold (P < 0.01) and 1.8-fold (P < 0.05) higher, HSD3B2 expression was 7.5- (P < 0.01) and 2.5-fold higher (P < 0.05), INHBA was 2.5-fold (P < 0.01) and 2.5-fold (P < 0.01) higher in GL cells from women who had received kisspeptin-54 than hCG or GnRHa, respectively. ESR1 (P < 0.05) and ESR2 (P < 0.05) both showed 3-fold higher expression in cells from kisspeptin treated than GnRHa treated women. Markers of vascular permeability and oocyte growth factors were unchanged (VEGFA, SERPINF1, CDH5, amphiregulin, epiregulin). Gene expression of kisspeptin receptor was unchanged. Whereas treating GL cells in vitro with hCG induced steroidogenic gene expression, kisspeptin-54 had no significant direct effects on either OHSS genes or steroidogenic genes. LIMITATIONS REASONS FOR CAUTION Most women in the study had PCOS, which may limit applicability to other patient groups. For the analysis of the in vitro effects of kisspeptin-54, it is important to note that GL cells had already been exposed in vivo to an alternate maturation trigger. WIDER IMPLICATIONS OF THE FINDINGS The profile of serum gonadotropins seen with kisspeptin administration compared to other triggers more closely resemble that of the natural cycle as compared with hCG. Thus, kisspeptin could potentially permit an ovarian environment augmented for steroidogenesis, in particular progesterone synthesis, which is required for embryo implantation.

Abstract
OBJECTIVE Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic condition, predominantly related to the hormone used to induce oocyte maturation during IVF treatment. Kisspeptin is a hypothalamic neuropeptide that has recently been demonstrated to safely trigger final oocyte maturation during IVF treatment even in women at high risk of OHSS. However, to date, the safety of kisspeptin has not been compared to current hormonal triggers of oocyte maturation. DESIGN We conducted a retrospective single-centre cohort study investigating symptoms and clinical parameters of early OHSS in women at high risk of OHSS (antral follicle count or total number of follicles on day of trigger ≥23) triggered with human chorionic gonadotrophin (hCG) (n = 40), GnRH agonist (GnRHa; n = 99) or kisspeptin (n = 122) at Hammersmith Hospital IVF unit, London, UK (2013-2016). RESULTS Clinical Parameters of OHSS: Median ovarian volume was larger following hCG (138 ml) than GnRHa (73 ml; P < .0001), and in turn kisspeptin (44 ml; P < .0001). Median ovarian volume remained enlarged 20-fold following hCG, 8-fold following GnRHa and 5-fold following kisspeptin compared to prestimulation ovarian volumes. Mean (±SD) ascitic volumes were lesser following GnRHa (9 ± 44 ml) and kisspeptin (5 ± 8 ml) than hCG (62 ± 84 ml; P < .0001). Symptoms of OHSS were most frequent following hCG and least frequent following kisspeptin. Diagnosis of OHSS: The odds ratio for OHSS diagnosis was 33.6 (CI 12.6-89.5) following hCG and 3.6 (CI 1.8-7.1) following GnRHa, when compared to kisspeptin. CONCLUSION Triggering oocyte maturation by inducing endogenous gonadotrophin release is preferable to the use of exogenous hCG in women at high risk of OHSS.

Abstract
Six indigenous Bangladeshi Garole sheep (Ovis aries) (BW: 8±0.5 kg; Age: 1yr) were divided into two groups using a randomized block design to investigate the effect of total mixed ration (TMR) pellet feeding on growth parameter, blood metabolomics, carcass and meat characteristics. Control diet was composed of road side grass, rice straw, wheat bran, mustard oil cake, molasses, common salt which considered as loose total mixed ration (L-TMR) and treatment diet was pelleted form of L-TMR (P-TMR).In both the dietary treatments the animals were fed at 1.5 times of maintenance energy and protein requirement. P-TMR revealed a positive impact (p < 0.05) on live weight gain and feed conversion ratio than L-TMR. Total digestible nutrients (TDN) and digestible crude fibre (DCF) was significantly higher (p < 0.05) in P-TMR group whereas there was no significant difference (p < 0.05) in other digestible nutrients as well as plasma metabolites like plasma glucose, triglyceride, total cholesterol, HDL-cholesterol and LDL- cholesterol concentration between two dietary group. Dressing percentage and eye muscle area was significantly higher (p < 0.05) in P-TMR group but no significant difference was found between dietary treatments in term of disposition of body fat, proximate composition of mutton, all the sensory parameters except tenderness and overall acceptability. So, it could be concluded that, the P-TMR might be fed to sheep for better growth performance and higher meat production rather than production of functional mutton.Progressive Agriculture 28 (3): 222-229, 2017

Abstract
OBJECTIVE To assess the impact of non-cavity-distorting fibroids on in vitro fertilisation (IVF) pregnancy outcomes. DESIGN A retrospective, matched, single-centre, cohort study was performed. SETTING The IVF unit of a tertiary, university hospital. POPULATION We analysed all women with non-cavity-distorting uterine fibroids undergoing IVF/intracytoplasmic sperm injection (ICSI) cycles from 1 January 2011 to 1 May 2015. METHODS Each woman was matched with two separate controls of the same age (±6 months), stimulation protocol (gonadotropin-releasing hormone agonist or antagonist), starting dose of follicle-stimulating hormone (FSH), number of embryos transferred (one or two), day of transfer (day 3 or day 5), and no uterine fibroids identified by transvaginal ultrasound. MAIN OUTCOME MEASURES Clinical pregnancy and live birth rates. RESULTS Our study demonstrates that the presence of non-cavity-distorting fibroids appears to negatively affect clinical pregnancy (odds ratio, OR 0.62; 95% confidence interval, 95% CI 0.41-0.94) and live birth rates (OR 0.58; 95% CI 0.48-0.78) in patients undergoing their first IVF/ICSI cycle, when matched with controls of the same age, starting dose of FSH, stimulation protocol, number of embryos, and day of embryo transfer. The deleterious effect of fibroids on live birth rates was significant in women with two or more fibroids (OR 0.47; 95% CI 0.26-0.83) and in women with fibroids of ≥30 mm in diameter (OR 0.41; 95% CI 0.19-0.89). The negative impact of non-cavity-distorting fibroids was also present in women with an embryo transfer on day 5 (OR 0.58; 95% CI 0.35-0.94). Conversely, in women with single fibroids of <30 mm in diameter, no difference in pregnancy outcomes was identified. CONCLUSIONS A well-designed, adequately powered, randomised controlled trial is required to address the role of medical or surgical interventions in patients with intramural and subserosal fibroids before undergoing fertility treatment. TWEETABLE ABSTRACT Non-cavity-distorting fibroids negatively affect pregnancy rates after IVF.

Abstract
BACKGROUND Complexity in medicine needs to be reduced to simple components in a way that is comprehensible to researchers and clinicians. Few studies in the current literature propose a measurement model that addresses both task and patient complexity in medicine. OBJECTIVE The objective of this paper is to develop an integrated approach to understand and measure clinical complexity by incorporating both task and patient complexity components focusing on the infectious disease domain. The measurement model was adapted and modified for the healthcare domain. METHODS Three clinical infectious disease teams were observed, audio-recorded and transcribed. Each team included an infectious diseases expert, one infectious diseases fellow, one physician assistant and one pharmacy resident fellow. The transcripts were parsed and the authors independently coded complexity attributes. This baseline measurement model of clinical complexity was modified in an initial set of coding processes and further validated in a consensus-based iterative process that included several meetings and email discussions by three clinical experts from diverse backgrounds from the Department of Biomedical Informatics at the University of Utah. Inter-rater reliability was calculated using Cohen's kappa. RESULTS The proposed clinical complexity model consists of two separate components. The first is a clinical task complexity model with 13 clinical complexity-contributing factors and 7 dimensions. The second is the patient complexity model with 11 complexity-contributing factors and 5 dimensions. CONCLUSION The measurement model for complexity encompassing both task and patient complexity will be a valuable resource for future researchers and industry to measure and understand complexity in healthcare.

Abstract
This prospective study was done to find out the epidemiological factors of suppurative corneal ulcer and the common causative bacterial and fungal isolates from the, patients with suppurative corneal ulcer in secondary and tertiary level hospital at Mymensingh region. A total 100 samples of corneal scrapings were collected purposively from clinically diagnosed suppurative corneal ulcer patients from March 18, 2012 to March 17, 2013. Out of the total 100 samples, bacterial species were 29(29%) cases and the fungal spacies were 71(71%) identified by the culture in blood agar, chocolate agar and sabouraud's agar media and also by microscopic examination. The bacterial species were streptococcus pneumonae 12 cases (12%), Staphylococcus aureus 9 cases (9%), pseudomonas in 6 cases (6%), and Streptococcus pyoganes 2 cases (2%). Fungal species were aspergillus fumigatus 61 cases (61%), aspergillus niger 10 cases (10%). Out of the study populations, most of the populations were from the age group of 41 to 60 years (39 %), followed 21 to 40 years (34%) age group. Considering the sex, male were 67%, female were 33%. The majority of patients came from the rural area of Mymensingh region; occupationally they were farmers (44%). Ocular trauma due to agricultural materials was the most common associated factor (71%). The etiological and epidemiological pattern of suppurative corneal ulcer varies significantly with geographical region, patient population and health of the cornea. The present study was carried out to explore the epidemiological pattern, causative bacterial and fungal specie by laboratory procedure from corneal scraping and to invent a prospective guide line for the management of corneal ulcer in the community.

Abstract
We stabilize a chosen radio frequency beat note between two optical fields derived from the same mode-locked laser pulse train in order to coherently manipulate quantum information. This scheme does not require access or active stabilization of the laser repetition rate. We implement and characterize this external lock, in the context of two-photon stimulated Raman transitions between the hyperfine ground states of trapped 171Yb(+) quantum bits.

Abstract
We control quantum fluctuations to create the ground state magnetic phases of a classical Ising model with a tunable longitudinal magnetic field using a system of 6 to 10 atomic ion spins. Because of the long-range Ising interactions, the various ground state spin configurations are separated by multiple first-order phase transitions, which in our zero temperature system cannot be driven by thermal fluctuations. We instead use a transverse magnetic field as a quantum catalyst to observe the first steps of the complete fractal devil's staircase, which emerges in the thermodynamic limit and can be mapped to a large number of many-body and energy-optimization problems.

Abstract
Pulmonary function test of various types are utilized clinically and epidemiologically to measures the functional status of the lung and to asses the diseases. Spirometric standard for healthy Bangladeshi adults aged 18-40 years is conducted in National Institute of Diseases of Chest and Hospital (NIDCH). This is cross sectional study is establish normal value of lung functions for Bangladeshi adult. Total of 995 (628 males & 367 females) healthy adults were selected to obtain lung function values; from a healthy adult those who attended in the hospital as a patients attended and healthy stuff of NIDCH. A computerized spirometer was used to measure lung volume and flows in a standard way. The best of the three reading was taken as the correct value. Anthropometric parameters including age, weight and height were recorded appropriately and body mass index was calculated. The statistical package for the social science (SPSS-10.01) was used for the statistical analysis of the data. The pulmonary function data was separated by sex and classified on the basis of height weight age and body surface area. The mean and standard deviation was calculated for every such variable. The lung function variable shows a linear positive correlation with height, weight and age. Force vital capacity (FVC) and forced expiratory volume in 1st second (FEV1) increase in height. Males show higher values for lung function variables than female. Stepwise regression analysis was done using age, height and weight, BMI as independent variable strong correlation was found between lung function values and independent variables. Height shows the highest correlation. The regression equation for lung function variables was determined for males and females considering height as independent variable. Lung function values of Bangladeshi adult were significantly lower than Nigerian, British and American result but nearly similar to Indian result. Nomogram was constructed in relation to height for males and females.

BACKGROUND Developing cities like Khulna, the third largest metropolitan city in Bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (NGOs) and community-based organizations (CBOs) in municipal solid waste (MSW) management. METHODS A survey was conducted to observe the present scenarios of secondary disposal site (SDS), ultimate disposal site (UDS), composting plants, medical wastes management and NGOs and CBOs MSW management activities. RESULTS A total of 22 NGOs and CBOs are involved in MSW management in 31 wards of Khulna City Corporation. About 9 to 12% of total generated wastes are collected by door-to-door collection system provided by mainly NGOs and CBOs using 71 non-motorized rickshaw vans. A major portion of collected wastes is disposed to the nearest SDS by these organizations and then transferred to UDS or to private low-lying lands from there by the city authority. A small portion of organic wastes is going to the composting plants of NGOs. CONCLUSION The participation of NGOs and CBOs has improved the overall MSW management system, especially waste collection process from sources and able to motivate the residents to store the waste properly and to keep clean the premises.
