Abstract
There isn't any vertical integration of pre-clinical and clinical sciences subjects in the existing Kathmandu University MBBS curriculum. Many of the graduates are not able to correlate the clinico-pathological aspects of various diseases as a result the rational use of investigations for diagnosing various diseases is compromised. There are few published examples of implementation of pathology instruction courses during the clinical years of medical training but it is not universally practiced. This lack of exposure to pathology may lead to poor understanding of laboratory testing and the role of pathologists in patient care. To set and implement an exemplary vertical integration of pre-clinical science with clinical science. A 12 credit hours clinical pathology education course comprising clinical hematology, cytopathology and histopathology was developed. Students belonging from the ongoing fourth year MBBS course of Birat Medical College were enrolled in the course. All of the interactive lecture sessions were delivered via an e-learning interface, using the Zoom platform as the main teaching methods. Evaluation of students' achievement of learning objectives was conducted through distributing pre and post-test online multiple-choice questionnaires. Chi-square tests were used to compare the variables between pre-test and post-test questionnaire responses. Results suggested that the designed clinical pathology course is valuable. The pretest and post-test questionnaire responses revealed the positive impact regarding the importance of introducing clinical pathology courses within the clinical year of MBBS undergraduate curriculum. Response rate to the online session was 100%. The point of agreement between the pre-test and post-test questionnaire responses were highly achieved after intervention of the clinical pathology course. A statistically significant result (p < 0.05) between all of the pre-test and post-test questionnaire responses was noted. There was a strong positive recommendation for incorporating clinical laboratory medicine courses within the MBBS clinical science curriculum. The improvement observed among fourth-year MBBS students on learning the importance of clinical pathology courses was encouraging. This experience thus contributed to set and implement an exemplary vertical integration of pre-clinical science with clinical science.

STATIN trial: predictive performance of competing-risks model in screening for pre-eclampsia at 35-37 weeks' gestation. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 59:69-75. [PMID: 34580947 DOI: 10.1002/uog.24789] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 09/17/2021] [Accepted: 09/17/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE To examine the predictive performance of a previously reported competing-risks model of screening for pre-eclampsia (PE) at 35-37 weeks' gestation by combinations of maternal risk factors, mean arterial pressure (MAP), uterine artery pulsatility index (UtA-PI), serum placental growth factor (PlGF) and serum soluble fms-like tyrosine kinase-1 (sFlt-1) in a validation dataset derived from the screened population of the STATIN study. METHODS This was a prospective third-trimester multicenter study of screening for PE in singleton pregnancies by means of a previously reported algorithm that combines maternal risk factors and biomarkers. Women in the high-risk group were invited to participate in a trial of pravastatin vs placebo, but the trial showed no evidence of an effect of pravastatin in the prevention of PE. Patient-specific risks of delivery with PE were calculated using the competing-risks model, and the performance of screening for PE by maternal risk factors alone and by various combinations of risk factors with MAP, UtA-PI, PlGF and sFlt-1 was assessed. The predictive performance of the model was examined by, first, the ability of the model to discriminate between the PE and no-PE groups using the area under the receiver-operating-characteristics curve (AUC) and the detection rate at a fixed false-positive rate of 10%, and, second, calibration by measurements of calibration slope and calibration-in-the-large. RESULTS The study population of 29 677 pregnancies contained 653 that developed PE. In screening for PE by a combination of maternal risk factors, MAP, PlGF and sFlt-1 (triple test), the detection rate at a 10% false-positive rate was 79% (95% CI, 76-82%) and the results were consistent with the data used for developing the algorithm. Addition of UtA-PI did not improve the prediction provided by the triple test. The AUC for the triple test was 0.923 (95% CI, 0.913-0.932), demonstrating very high discrimination between affected and unaffected pregnancies. Similarly, the calibration slope was 0.875 (95% CI, 0.831-0.919), demonstrating good agreement between the predicted risk and observed incidence of PE. CONCLUSION The competing-risks model provides an effective and reproducible method for third-trimester prediction of term PE. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
AIMS To prospectively examine the outcomes, toxicity and quality of life (QoL) of patients with post-cricoid and upper oesophagus (PCUE) cancers treated with an organ-preservation approach of (chemo)-radiotherapy using intensity-modulated image-guided radiotherapy (IM-IGRT). MATERIALS AND METHODS This phase II prospective study was conducted at a tertiary cancer centre from February 2017 to January 2020. Forty patients with squamous cell carcinoma of PCUE of stage T1-3, N0-2, M0 were accrued. Gross exolaryngeal extension/dysfunctional larynx were major exclusion criteria. Patients received 63-66 Gy in once-daily fractions using volumetric modulated arc therapy with daily IGRT. Outcome measures included disease-related outcomes, patterns of failure, Radiation Therapy Oncology Group toxicities, feeding tube dependency and QoL. RESULTS The median follow-up was 22 months. Twenty-six (87.5%) patients had locoregionally advanced disease and 34 (85%) patients received (chemo)-radiotherapy. A complete response was observed in 26 (65%) patients. The 2-year locoregional control, event-free survival and cause-specific survival were 59.6%, 40.2% and 44.8%, respectively. The volume of primary tumour (GTVPvol) exceeding 28 cm3 had inferior overall survival (P = 0.005) on univariate analysis. Multivariable analysis showed GTVPvol and positron emission tomography-computed tomography maximum standardised uptake value to be independently predictive for event-free and overall survival. A feeding tube requirement at presentation was seen in 11 (27.5%) patients, whereas long-term feeding tube dependency at 6 months was seen in 10 (37%) patients. For QoL, a statistical improvement in pain, appetite loss and swallowing was observed over time. CONCLUSION Although the outcomes of PCUE cancers remain dismal, the use of state of the art diagnostic modalities, careful case selection and modern radiotherapy techniques improved outcomes as compared with before in this exclusive analysis of PCUE cancers.

Abstract
Background Chronic otitis media (COM) remains a major public health issue and is associated with relentless discharge from the ear, pain, significant functional limitation of hearing, leading to communication problems and frequent specialist visits. Aims To assess the improvement in quality of life of patients of COM (safe type) and surgical success in terms of graft uptake and improvement in hearing. Patients and Methods A prospective questionnaire-based outcome study was directed in 100 patients with COM who were treated with Type I Tympanoplasty at our institution between May 2018 and May 2020. All patients were asked to fill Modified Chronic Otitis Media 4 (COM-4) survey before operation and 3 months after operation. Preoperative and postoperative total ear scores, audiological results, postoperative graft uptake were assessed. Results The correlation between preoperative and postoperative assessment by questionnaire was statistically critical (P < 0.001). There was significant improvement in hearing postoperatively (P < 0.001). Effective graft uptake was seen in 80%. Conclusion The current study emphasizes that Type 1 Tympanoplasty fundamentally improves quality of life of patients in terms of physical suffering, hearing loss, emotional distress postoperatively.

Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
Introduction/Aim
Public defibrillation doubles out-of-hospital cardiac arrest survival. However, the best way to provide public defibrillation coverage to geographically dispersed populations remains unknown. The aim of this study is to compare usage rates and effectivity between mobile versus fixed Automated External Defibrillators (AED).
Methods
This project is a prospective registry of the usage rate of public AED (542 fixed AED, 241 mobile AED) and the analysis of the electrocardiographic traces, from June 2011 until December 2019. We compared the usage rate, the proportion of shockable rhythms and defibrillation success between fixed versus mobile AED.
Results
Of 566 registered usages, we obtained 494 electrocardiographic traces, of which 108 (21%) were from fixed AED. The usage rate of fixed and mobile AED were 0.022use/AED-year and 0.177use/AED-year respectively. In Fixed AED group we observed a higher proportion of shockable rhythms (34.2% vs. 20.3%, p=0,01) and higher defibrillation success (79% vs. 63%, p=0,02). The proportion of patients with shockable rhythms who were transferred to a hospital were 62.1% and 50% in Fixed AED and Mobile AED group respectively (p=0,306).
Conclusions
In Fixed AED group we observed more shockable rhythms and higher defibrillation success rates. Mobile AED were 8 times more used.

Abstract
Purpose In early 2020, the world is amid a significant pandemic due to the novel coronavirus disease outbreak, commonly called the COVID-19. Coronavirus is a lung infection disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 virus (SARS-CoV-2). Because of its high transmission rate, it is crucial to detect cases as soon as possible to effectively control the spread of this pandemic and treat patients in the early stages. RT-PCR-based kits are the current standard kits used for COVID-19 diagnosis, but these tests take much time despite their high precision. A faster automated diagnostic tool is required for the effective screening of COVID-19. Methods In this study, a new semi-supervised feature learning technique is proposed to screen COVID-19 patients using chest CT scans. The model proposed in this study uses a three-step architecture, consisting of a convolutional autoencoder based unsupervised feature extractor, a multi-objective genetic algorithm (MOGA) based feature selector, and a Bagging Ensemble of support vector machines based binary classifier. The proposed architecture has been designed to provide precise and robust diagnostics for binary classification (COVID vs.nonCOVID). A dataset of 1252 COVID-19 CT scan images, collected from 60 patients, has been used to train and evaluate the model. Results The best performing classifier within 127 ms per image achieved an accuracy of 98.79%, the precision of 98.47%, area under curve of 0.998, and an F1 score of 98.85% on 497 test images.

Abstract
Study question
Does GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to GCSF by the subcutaneous route, in IVF-ICSI Cycles?
Summary answer
Yes, GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to subcutaneous-GCSF, in ART Cycles?
What is known already
GCSF, is a member of the colony stimulating factor family of cytokines and growth factors. GCSF receptors are expressed in high concentration on dominant follicle, particularly at preovulatory stage.The endometrium also shows an increased expression of these receptors. GCSF concentration rises in the follicular fluid at the same time. Serum levels of GCSF are found to be in direct correlation with levels of GCSF in follicular fluid. Serum levels increase progressively from the day the embryo-transfer to the day of implantation. GCSF has been found to be beneficial in patients with thin endometrium and recurrent implantation failure.
Study design, size, duration
This was a RCT conducted between 2018–2019. 30 patients with thin endometrium were enrolled in each group. In either group, GCSF was given if endometrium was less than 7mm on day 14, maximum of two doses were administered. Patients undergoing frozen embryo transfer were recruited in the study, after meeting the inclusion and exclusion criteria. Primary outcome measured was increase in endometrium thickness and the secondary outcome was the clinical pregnancy rate and abortion-rate.
Participants/materials, setting, methods
60 patients with thin endometrium were randomly divided into two groups. Group A: Inj. GCSF (300 mcg/1 ml) subcutaneously on Day 14 onwards alternate days for two doses. Group B: Inj. GCSF (300 mcg/1 ml) instilled slowly into the uterine cavity using an intrauterine insemination (IUI) catheter under USG guidance. Endometrial thickness was assessed after 48 h. If endometrial thickness was found to be < 7 mm, a second infusion of GCSF was carried out.
Main results and the role of chance
In the subcutaneous group (group-A) the mean endometrial thickness before GCSF injection was 5.8 ± 0.6 mm and, after injection it increased to 6.9 ± 0.4 mm. Similarly, in the intrauterine group (group-B) the mean endometrial thickness before GCSF was 5.9 ± 0.7 which increased to a mean of 7.9 ± 0.5 after GCSF instillation. The difference between endometrial thickness before and after intrauterine infusion of GCSF was more than that in the subcutaneous group. In group-A, 08 patients conceived out of 30 patients ( clinical pregnancy rate 26.6%) and in group B 11 conceived out of 30 patients in whom GCSF was instilled intrauterine (pregnancy rate 36.6%). Thus, there was a difference in the clinical pregnancy rate in the two groups, the intrauterine group yielding a higher clinical pregnancy rate, but it was not statistically significant. Because of the thin endometrium, we found an abortion rate of 25% (2/8) in the subcutaneous-GCSF group, and an abortion rate of 18% (2/11) in the intrauterine GCSF group.
Limitations, reasons for caution
There are few potential limitations because of the small sample size. Confounders such as obesity, smoking and alcohol intake, presence of adenomyosis and endometriosis, were not taken into consideration. Though prevalence of obesity is usually low in Indian women. Habits of smoking and alcohol are exceedingly uncommon in Indian women.
Wider implications of the findings: Use of GCSF plays an important role in management of patients of thin endometrium undergoing embryo transfer. It is an easily available and economical preparation in developing countries and the intrauterine instillation of GCSF can be easily practiced in an ART unit with good results in resistant thin endometrium patients.

Abstract
Abstract
Study question
Is the outcome of IVF/ICSI cycles done with continuous (single step ) embryo culture system different from that with sequential embryo culture system ?
Summary answer
Yes the outcome of IVF / ICSI cycles done with continuous (single step ) embryo-culture system is better than that with sequential embryo-culture system .
What is known already
Embryo culture media are important factors in IVF, which can significantly influence the clinical outcome of IVF/ICSI cycles. However it is not clear which formulation is most optimal and whether sequential or continuous media (single step) should be favored. Sequential media complies with embryo demands based on developmental stage , taking into account metabolic changes embryos undergo in-vivo, while moving from the oviduct to the uterus. The embryos in the early cleavage stage prefer to use pyruvate to produce energy, whereas once development nears the blastocyst stage , the embryos start using glucose in the process of glycolysis .
Study design, size, duration
A prospective RCT was carried out at our centre between 2018–2019 and IVF-ICSI patients meeting inclusion criteria (at least six normal MII - Oocytes) were included in this study. The aim of study was to compare blastocyst formation rates after embryo-culture in two different culture media systems. 436 metaphase II Oocytes from 62 women were randomly and equally divided to be fertilized and cultured to the blastocyst stage in either sequential media or single-step media.
Participants/materials, setting, methods
In this prospective trial with sibling oocytes, 436 metaphase II oocytes from 62 women were randomly and equally divided to be fertilized and cultured to the blastocyst stage in either sequential media ( n = 218 MII oocytes) or a single medium ( n = 218 MII oocytes). In both groups, embryos were cultured in an interrupted fashion with media changes on day 3. Embryo transfer was performed on day 5.
Main results and the role of chance
Blastocyst formation rates on day 5 were significantly higher following culture in single step media 60.55% (132 / 218 ) as compared to sequential media 34.86% ( 76 / 218) . The percentage of good quality blastocysts was also significantly higher in single step media. In conclusion, culture in single step media was associated with higher blastocyst formation rates compared to sequential media , suggesting that the single medium may provide better support to the developing embryo. The proportion of poor quality embryos was significantly higher in the sequential media group. Results indicate that embryo culture in continuous media could be as efficient as embryo culture in sequential media. A significant difference observed was the proportion of poor quality embryos on day 5 , which was significantly higher when the embryos were cultured in sequential media. Our results suggest that the type of embryo culture media can influence the quality of embryos both at the cleavage stage and blastocyst stage. The use of continuous embryo culture media does not seem to cause an adverse effect; in fact, their use can lower the workload in busy IVF labs and lower the stress that embryos are exposed to during handling.
Limitations, reasons for caution
Although single-step-medium for extended culture has practical advantages and blastocyst formation rates appear to be higher, there is insufficient evidence to recommend either sequential or single-step media as being superior for the embryo-culture to days 5/6. Further studies comparing these two media systems in well-designed trials should be performed.
Wider implications of the findings: When employing sequential media for embryo culture , it is necessary to transfer the embryos from one medium to another ( cleavage stage medium to blastocyst stage medium) which increases stress related embryo damage . Therefore, single-step media is beneficial as the embryos can develop undisturbed till blastocyst stage.

Singh M, Singh R. P–169 Does increasing the time interval between Oocyte-Retrieval and Oocyte-Denudation improve the results in ICSI cycles ? Hum Reprod 2021.

Abstract
Abstract
Study question
What should be the optimal time interval which elapses between oocyte retrieval and denudation followed by ICSI , for optimal results in ART cycles ?
Summary answer
Our study suggests that an optimum interval between oocyte retrieval and oocyte denudation followed by ICSI, leads to better results in ART cycles.
What is known already
It is widely accepted that the best timing for OPU is 34–39 hours after ovulation trigger. Some studies suggest that preincubation time before ICSI can be beneficial when it comes to fertilization and pregnancy rates while late ICSI (fertilization) may have negative results due to oocyte ageing. Other studies claim that there is no significant difference in ART results when ICSI is performed between 2–6 hours post Oocyte-Retrieval (OR) . Few studies state that 1–3 hours of COC-culture prior to denudation and oocyte injection is better as far as fertilization , embryo quality and improved oocyte cytoplasmic maturity is concerned.
Study design, size, duration
RCT of 234 ICSI cycles was carried out between 2017–2019. Patients were divided into two groups-: A- Early denudation with ICSI and B- Late denudation with ICSI.Both the groups were comparable in terms of female age, number of oocytes, day of transfer, number of embryos transferred and embryo quality. Fresh or frozen embryos were transferred , which were always derived from the same stimulation cycle. Exclusion criteria were : Severe male factor / TESA / PESA.
Participants/materials, setting, methods
234 ICSI cycles with similar ovarian stimulation protocols were analyzed as per time range between triggering, OPU, denudation and ICSI. Patients were divided into two groups: A- Early denudation (1–2 hours after OPU) with ICSI (1–2 hours after denudation) and B- Late denudation (4–6 hours after Oocyte-Retrieval ) with ICSI (1–2 hours after denudation).Primary outcomes were oocyte maturation and fertilization rates and secondary outcomes were clinical pregnancy rate and abortion rates.
Main results and the role of chance
In group B ( Late denudation and ICSI), the mean fertilization rate was 67% and the Clinical Pregnancy rate was 46%. This was better than the mean fertilization rate of 56% and clinical pregnancy rate of 39% observed in group A ( Early denudation and ICSI). However the difference was not statistically significant. Therefore, ideal maturation rates were observed when denudation ( followed by ICSI ) was delayed and done 4–6 hours after Oocyte-Retrieval. In ICSI cycles in ART , ovarian stimulation is used to induce the simultaneous growth of multiple follicles, followed by final maturation and ovulation triggering with exogenous hCG. or GnRH-Agonist or both. Generally, oocyte retrieval (OR) is performed 34 - 36h later. In addition, 2–4 hours in culture of the cumulus oocyte complexes (COC) prior to oocyte injection is believed beneficial for fertilization and embryo quality, probably due to improved oocyte cytoplasmic maturity. However, in large ART centers with high workloads, following such definite time intervals is frequently very difficult.
Limitations, reasons for caution
In large busy centers , maintaining meticulous time intervals is difficult . As our study numbers are small, larger multicentric trials are required in order to confirm our findings and to provide more robust data . This data cannot be applied to IVM, TESE / PESE and severe male-factor infertility.
Wider implications of the findings: To achieve a successful fertilization, both nuclear and cytoplasmic maturity are required. Our Study indicates that a slight delay in denudation following Oocyte-Retrieval , will yield a higher number of good quality oocytes. A higher success rate can also be expected due to more number of embryos available for transfer.

Jindal A, Singh M. O-230 RCT comparing Recombinant-hcg trigger with Dual-trigger (GnRH-agonist and recombinant-hcg ) in improving clinical outcome in ICSI cycles in women with Diminished Ovarian Reserve.

Abstract
Abstract
Study question
Does use of Dual-trigger (GnRH-agonist with recombinant-hcg) improve the clinical outcome in women with diminished ovarian reserve as compared to Recombinant-hcg trigger?
Summary answer
Yes, the use of Dual-trigger (GnRH-agonist with recombinant-hcg) improve the clinical outcome in women with diminished ovarian reserve as compared to Recombinant-hcg trigger.
What is known already
The population of poor responders has grown exponentially over the years and their management of ovarian stimulation remains one of the most challenging aspects. In GnRH antagonist down-regulated IVF-ICSI cycles, dual triggering for the final oocyte maturation with GnRH-a and a reduced dose of hCG improves the rate of fertilization and clinical pregnancy in women with diminished ovarian reserve. Further more, the benefit of lowered cycle cancellation rate would also enable greater percentage of patients with diminished ovarian reserve to reach the final stage of their ART treatment, thereby enhancing their chances of achieving a successful pregnancy .
Study design, size, duration
This RCT included GnRH antagonist ICSI cycles from 2018-2019. 82 women with diminished ovarian reserve (AMH ≤ 1.1 ng/ml and AFC ≤5) were included. The primary outcome measured was the oocyte fertilization rate, implantation rate and clinical pregnancy rate per oocyte retrieval cycle. Secondary outcome measured was embryo transfer cancellation rate and abortion rate per oocyte retrieval cycle.
Participants/materials, setting, methods
82 women with diminished ovarian reserve undergoing fresh embryo transfer were included and randomly divided in two groups - Group-A (hCG trigger/control group: n = 41); and Group-B (dual trigger/study group: n = 41). Both patient groups underwent controlled ovarian stimulation using antagonist. The final oocyte maturation was triggered either by recombinant hCG (Group-A) or by a combination of recombinant hCG and GnRH-agonist (Dual trigger) (Group-B).
Main results and the role of chance
The dual-trigger group had significantly higher fertilization rate (62.8 vs. 37.6%), higher clinical pregnancy rate (31.4% vs. 18.1%) as compared to the recombinant-hCG trigger group. In addition, the abortion rate(12.1% vs. 21.3%) and embryo transfer cancellation rate (8.3% vs. 16.1%) were both significantly lower in the dual trigger group. The baseline characteristics for the control and the study group were similar and there was no significant difference in the patient age, serum AMH level, and cause of infertility. The total r-FSH dose, duration of stimulation, endometrial thickness, and serum hormone profile on the day of trigger were also similar between the control and the study group. The main advantage of triggering with GnRH-a is that it induces a mid-cycle FSH surge which resembles the natural ovulatory cycle hormonal changes. Study shows that in GnRH antagonist ART cycles, dual triggering with GnRH-a and hCG could significantly improve the rate of fertilization and clinical pregnancy in diminished ovarian reserve women. Furthermore, the benefit of lowered cycle cancellation rate would also enable greater percentage of patients with diminished ovarian reserve to reach the final stage of their ART treatment thereby enhancing their chance of achieving a successful pregnancy as well as reducing their mental stress.
Limitations, reasons for caution
The main limitation of our study is the low patient number. Triggering with GnRH-a has become a significant part of contemporary ART practice, especially in high responders, oocytes donors and oncology patients. However, more RCTs are required in order to justify the use of GnRH-agonists in poor responders in ART cycles.
Wider implications of the findings
Results of our study concurred with other studies of dual triggering, calls for a possible paradigm shift in ovulation-triggering agent for GnRH-antagonist cycles. Diminished ovarian reserve patients are constituting a large part of clinical ART practice and for such patients, obtaining maximum mature oocytes and good embryos is vitally important.

Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
Guava (Psidium guajava L.) is one of the most important tropical fruits belonging to
the genus Psidium and the Myrtaceae family and claim to have phenolic compounds
that have been reported to possess strong antioxidant activity. This study was aimed to
evaluate the bioactive constituents in guava cultivars at different ripening stages by
HPLC. The five guava cultivars were selected at different ripening stages and the
bioactive components were analysed by high-pressure liquid chromatography. The
quantification of bioactive compounds revealed that the highest amount of bioactive
compounds was found in cultivar Safeda at the unripe stage, while a minimum amount
was found in ripe Apple Colour guava cultivar. The six bioactive compounds were
quantified in the range of gallic acid (9.46-63.08 mg/100 g), quercetin (0.11-2.51
mg/100 g), myrcetin (0.09-0.034 mg/100 g), ascorbic acid (7.45-75.07 mg/100 g),
apegenin (0.01-0.032 mg/100 g) and lycopene (0.34-0.92 mg/100 g). The exploratory
evaluation of guava samples was performed through Principal Component Analysis
(PCA), the bioactive compounds, lycopene, myricetin, and quercetin are dominant
variables on this PC1 (61.52%) (Scores better than 0.7), thereby causing greater
variability among these samples. The second principal component (PC2) represents
16.54% of the total variance and the ascorbic acid, gallic acid and apeginin (score
better than 0.7), are the dominant variables on this PC.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Poult Sci 2021; 100:101206.

Abstract
Peroxyacetic acid (PAA) is a widely used antimicrobial during poultry processing that requires to be shipped in a concentrated solution, stored under hazardous conditions and diluted for use. On-site PAA generation using nonhazardous ingredients can help eliminate transportation and storage issues at the processing plant and reduce the risk of occupational hazards. The objective of the proposed research was to 1) evaluate the efficacy of on-site generated PAA in reducing Salmonella and Campylobacter populations compared to the commercially available PAA stock solutions and 2) to perform color measurements to evaluate any deviations between treatments. PAA solutions at 50 and 100 ppm were used for treating the chicken wings. Fresh chicken wings (0.45 kg) were inoculated with a cocktail of nalidixic acid resistant Salmonella Typhimurium (STNR) and gentamicin resistant Campylobacter coli (CCGR) and immersed in PAA solutions (50 and 100 ppm) adjusted to pH 8.5 and 10.0 or 10.5, for either 10 s or 60 min. Treated chicken wings were rinsed for 1 min in chilled BPW (100 mL), serially diluted and plated on APC Petrifilm for Salmonella, spread plated on Campy-cefex agar supplemented with gentamicin (200 ppm) for Campylobacter enumeration. Immersion of chicken wings in 100 ppm PAA for 60 min irrespective of pH levels and PAA solutions resulted in greater microbial reductions (P < 0.05) of Salmonella by 1.68 and 1.42 log CFU/mL for SaniDate, 1.82 and 1.83 log CFU/mL for OxyFusion (on-site generated). For the same treatments, Campylobacter reductions of 1.59 and 1.36 log CFU/mL for SaniDate, 1.63 and 1.71 log CFU/mL for OxyFusion were achieved. The antimicrobial efficiency of PAA was not affected by pH and type of PAA solution. No significant differences (P > 0.05) in color were observed between treatments and controls. On-site generated PAA provides poultry processors an effective, safer, and less hazardous alternative to commercially available PAA solutions, ensuring poultry workers’ health and safety.

Abstract
OBJECTIVE The implementation of clinical quality indicators for monitoring cancer care in regional, rural and remote areas. DESIGN Retrospective data from a population-based Clinical Quality Registry for lung, colorectal and breast cancers. SETTING All major health services in the Barwon South Western region, Victoria, Australia. PARTICIPANTS All patients who were diagnosed with cancer and who presented to a health service. INTERVENTION(S) Clinical subgroups to review variations. MAIN OUTCOME MEASURES(S) Clinical quality indicators for lung, colorectal and breast cancers. RESULTS Clinical indicators included the following: discussion at multidisciplinary meetings, the timeliness of care provided and the type of care for different stages of the disease and survival outcomes. Many of the derived clinical indicator targets were reached. However, variations led to an improvement in the tumour stage being recorded in the medical record; an improved awareness of the need for adjuvant chemotherapy for colorectal cancer; a reduction in time to treatment for lung cancer and a reduced time to surgery for breast cancer, and the 30-day mortality post-treatment for all of the tumour streams was highlighted. CONCLUSIONS Clinical quality indicators allow for valuable insights into patterns of care. These indicators are easily reproduced and may be of use to other cancer centres and health services.

Abstract
INTRODUCTION Laparoscopic pyloromyotomy is now an accepted procedure for the treatment of pyloric stenosis. However, it is clear that during the implementation period there are significantly higher incidences of mucosal perforation and incomplete pyloromyotomy. We describe how we introduced a new laparoscopic procedure without the complications associated with the learning curve. MATERIALS AND METHODS Five consultants tasked one surgeon to pilot and establish laparoscopic pyloromyotomy before mentoring the others until they were performing the procedure independently; all agreed to use exactly the same instruments and operative technique. This involved a 5mm 30-degree infra-umbilical telescope with two 3mm instruments. Data were collected prospectively. RESULTS Between 1 January 2013 and 31 December 2017, 140 laparoscopic pyloromyotomies were performed (median age 27 days, range 13-133 days, male to female ratio 121:19). Fifty-five per cent of procedures were performed by trainees. Complications were one mucosal perforation and one inadequate pyloromyotomy. There were no injuries to other organs, problems with wound dehiscence or other significant complications. The median time of discharge was one day (range one to six days). CONCLUSION Our rate of perforation and incomplete pyloromyotomy was 1.4%, which is equivalent to the best published series of either open or laparoscopic pyloromyotomy. We believe that this resulted from the coordinated implementation of the procedure using a single technique to reduce clinical variability, increase mentoring and improve training. This approach appears self-evident but is rarely described in the literature of learning curves. In this age of increased accountability, new technologies should be incorporated into routine practice without an increase in morbidity to patients.

Abstract
Barn production systems in Australia are either an indoor-housing floor system or an aviary system with multilevel structures, equipped with nesting boxes, perches and feeding and watering systems. These systems offer hens the freedom of movement and an opportunity to display a repertoire of favourable behaviours as well as interact with complex housing elements as compared with caged systems. However, the system can create prospects for the hens to express detrimental behaviours such as feather pecking and cannibalism. Other aspects of welfare that may be compromised when compared with cage systems include incidence of fractures and injuries during navigation of hens among elements of housing that may result in collision or falls. Barn production systems may have an advantage over free-range production systems in relation to the protection they offer from predators and predator stress, and diseases and parasites that can be contracted from range areas. Barn systems also offer better biosecurity due to lack of direct access to wild birds and their faeces. The aim of the present review is to assess the welfare status of birds housed in barn (and aviary) production systems, while considering husbandry factors that affect welfare outcomes, the health and disease implications and sustainability. To maintain a high welfare outcome in barn production systems, it is important to keep the enclosed environmental conditions optimum by managing air quality, ventilation and lighting within sheds. Sustainability of these production systems depends on consumer preference, cost of production, environmental footprint and suitable genetics of hens.

Abstract
Slow-growing broilers offer differentiation in the chicken meat market for consumers who have distinct preferences based on perceived higher welfare indices and willingness to pay a higher price for the product. Although breeding for slow-growing broilers is relatively advanced in Europe and the United States, it is limited in Australia. Crossbreeding is one of the approaches taken to developing slow-growing broiler strains. Thus, the aim of this study was to compare performance, immune response, leg health, carcass characteristics, and meat quality of a novel crossbred slow-growing broiler breed (SGB) with the conventional, fast-growing Cobb 500 broiler (CB) to assess their suitability as an alternative for chicken meat production in Australia. A total of 236 one-day-old broiler chicks (116 SGB and 120 fast-growing CB) were reared on standard commercial diet in an intensive production system. Birds and feed were weighed on a weekly basis and feed intake and feed conversion ratio calculated. At 21 d of age, a 2% suspension of sheep red blood cells was injected subcutaneously into 8 broilers of each breed to compare their antibody response. Birds from both breeds were grown to a final live weight of 2.0–2.2 kg, before a latency-to-lie (LTL) test, carcass analysis and apparent metabolizable energy (AME) assay were performed. The SGB reached the target weight at 55 d of age compared with 32 d in CB. However, SGB stood for longer during LTL, had higher thigh, drumstick, and wing yields (as a percentage of carcass weight) as well as darker and redder meat in comparison with the CB. The CB had better feed conversion efficiency, higher antibody (IgM) production, higher AME, heavier breast yield, and lower meat drip loss than the SGB. Although fast-growing CB outperformed the SGB for traditional performance parameters, the crossbred in this study was comparable with other slow-growing broiler breeds and strains across different countries and is thus a suitable candidate for a slow-growing alternative in Australia.

Abstract
Breast cancer is a common cause of brain metastases, with metastases occurring in at least 10-16% of patients. Longer survival of patients with metastatic breast cancer and the use of better imaging techniques are associated with an increased incidence of brain metastases. Current therapies include surgery, whole-brain radiation therapy, stereotactic radiosurgery, chemotherapy and targeted therapies. However, the timing and appropriate use of these therapies is controversial and careful patient selection by using available prognostic tools is extremely important. Expert oncologist discussed on the mode of treatment to extend the OS and improve the quality of life ofHER2-positivebreast cancer patients with Solitary brain metastases. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Axillary lymph node involvement is a very important poor prognostic factor in the clinical staging and management of breast cancer patients. Traditionally, axillary lymph node dissection (ALND) has been used for determining the status of the axillary lymph nodes. More recently the sentinel lymph node biopsy (SLNB) procedure has gained wider acceptance as the standard of care, having the advantage of being less invasivewhile providing good accuracy. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of the two different procedures and other issues in patients with early breast cancer for the benefit of community oncologists.

Abstract
Optimization of adjuvant systemic therapy in women with early-stage hormone receptor-positive breast cancer includes the consideration of chemotherapy and duration of hormone therapy. Adjuvant hormonal therapy significantly improves long-term survival of breast cancer patients with hormone receptor-positive disease. Despite the proven clinical efficacy of tamoxifen and aromatase inhibitors, many breast cancer survivors either fail to take the correct dosage at the prescribed frequency (adherence) or discontinue therapy (persistence). Expert oncologist discussed on the duration of adjuvant hormonal therapy for improvement of OS and quality of life of breast cancer patients by providing reduction in recurrence and mortality. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Abstract
The Xpert MTB/RIF Ultra is a recent advancement in molecular diagnostics of tuberculosis (TB) with higher sensitivity compared to its predecessor, the Xpert MTB/RIF assay. Prospective studies evaluating the performance of Xpert MTB/RIF Ultra in children with suspected TB are lacking. In this study, we evaluated the Xpert MTB/RIF Ultra for detection of Mycobacterium tuberculosis in samples from 156 children, of which one was excluded from the analysis. Of the remaining 155 samples, 6·5% (10/155), 21·3% (33/155), 20% (31/155) and 21·9% (34/155) were positive by smear examination, MGIT culture, Xpert MTB/RIF and Xpert MTB/RIF Ultra, respectively. The Xpert MTB/RIF and Xpert MTB/RIF Ultra had a similar overall sensitivity of 81·8% (95% CI: 64·5-93) and 84·8% (95% CI: 68·1-94·9), respectively. In suspected pediatric TB patients, the Xpert MTB/RIF Ultra had higher sensitivity compared to the Xpert MTB/RIF (72·7 vs 63·6). The AUC (area under the curve) of 0·905 for the Xpert MTB/RIF and 0·893 for the Xpert MTB/RIF Ultra indicate similar and good overall performance. Both Xpert assays were found to be equally efficient, however Xpert MTB/RIF Ultra showed better detection rate in suspected TB cases.

Abstract
Peroxy acetic acid (PAA) is widely used as an antimicrobial in poultry processing, specifically in the chiller. While the natural pH of PAA at the concentrations used is between 4.5 and 6.0, poultry processors adjust the pH to ≥8.0 to maintain product yield. The objective of this study was to evaluate 1) efficacy of PAA at different concentrations, pH, and contact times against Salmonella, Campylobacter, and Escherichia coli and 2) use of E. coli as a surrogate for Salmonella and Campylobacter to conduct validations studies for poultry processing. Fresh chicken wings (0.45 Kg) were inoculated with a cocktail of nalidixic acid-resistant Salmonella Typhimurium, rifampicin-resistant E. coli (5-strain cocktail), and gentamicin-resistant Campylobacter coli. Inoculated chicken wings were immersed in PAA solutions of 50, 250, and 500 ppm adjusted to pH 8.2 and 10.0 as well as nonadjusted PAA solutions for 10 s and 60 min. Treated chicken wings were rinsed in chilled buffered peptone water, serially diluted, and plated on Petrifilm APC for enumerating Salmonella and E. coli populations and spread plated on Campy Cefex Agar containing gentamicin (200 ppm) to enumerate Campylobacter. Immersion of chicken wings in 500 ppm of PAA (non-pH-adjusted) for 60 min resulted in greater microbial reductions (P ≤ 0.05) of Salmonella, Campylobacter, and E. coli populations of 2.56, 1.90, and 2.53 log CFU/mL, respectively. Higher concentrations and longer exposure times resulted in greater reductions (P ≤ 0.05) of Salmonella, E. coli, and Campylobacter populations, and increasing pH of PAA solution did not affect (P > 0.05) its efficacy. A high correlation (r = 0.93) was observed between E. coli (surrogate) and Salmonella populations suggesting that E. coli can be used as a surrogate for Salmonella for conducting validation studies for antimicrobial efficacy testing in poultry processing.

Abstract
Coupling of the El Niño-Southern Oscillation (ENSO) and Indian monsoon (IM) is central to seasonal summer monsoon rainfall predictions over the Indian subcontinent, although a nonstationary relationship between the two nonlinear phenomena can limit seasonal predictability. Radiative effects of volcanic aerosols injected into the stratosphere during large volcanic eruptions (LVEs) tend to alter ENSO evolution; however, their impact on ENSO-IM coupling remains unclear. Here, we investigate how LVEs influence the nonlinear behavior of the ENSO and IM dynamical systems using historical data, 25 paleoclimate reconstructions, last-millennium climate simulations, large-ensemble targeted climate sensitivity experiments, and advanced analysis techniques. Our findings show that LVEs promote a significantly enhanced phase-synchronization of the ENSO and IM oscillations, due to an increase in the angular frequency of ENSO. The results also shed innovative insights into the physical mechanism underlying the LVE-induced enhancement of ENSO-IM coupling and strengthen the prospects for improved seasonal monsoon predictions.

Abstract
Quail (Coturnix japonica) is processed and marketed as fresh meat, with limited shelf life. The objective of this study was to evaluate the efficacy of antimicrobial interventions during slaughter on reducing Salmonella and Campylobacter contamination and to determine the microbiological shelf life of quail during refrigerated (4°C) storage. Three antimicrobials, peracetic acid (400 ppm; PAA), Citrilow (pH 1.2), and Cecure (cetylpyridinium chloride [CPC], 450 ppm), along with a water and no-treatment control were evaluated. Quail carcasses (n = 75) were inoculated with a cocktail of nalidixic acid–resistant Salmonella Typhimurium and gentamicin-resistant Campylobacter coli. After 30 min of attachment time, quail carcasses were submerged in each antimicrobial solution for 20 s with air agitation. Noninoculated quail carcasses (n = 25) were similarly treated, packaged, and stored under refrigeration (4°C). Aerobic plate counts (APC), psychrotroph counts (PC), Enterobacteriaceae counts (ENT), total coliform counts (TCC), and Escherichia coli counts on quail carcasses were determined on 1, 4, 7, and 10 d. Salmonella and Campylobacter populations were determined by plating on Petrifilm APC supplemented with 200-ppm nalidixic acid and Campy Cefex agar supplemented with 200-ppm gentamycin, respectively. No significant reductions in (P > 0.01 log cfu/mL) in APC, PC, ENT, TCC, and E. coli counts were observed on carcasses submerged in water. However, treatments with PAA, Citrilow, and CPC significantly reduced (P ≤ 0.05) Salmonella and Campylobacter coli contamination. Citrilow showed greater (P ≤ 0.05) reduction in Salmonella and Campylobacter population (1.90 and 3.82 log cfu/mL reduction, respectively) to PAA and CPC. Greater (P ≤ 0.05) reductions in APC, PC, ENT, TCC, and E. coli counts (2.22, 1.26, 1.47, 1.52, and 1.59 log cfu/mL, respectively) were obtained with the application of CPC. Application of antimicrobial interventions resulted in a reduction in Campylobacter and Salmonella, APC, PC, and ENT populations after treatments (day 0) and throughout the storage period (day 10). Use of antimicrobial interventions after slaughter can improve the microbiological safety and shelf life of quail.

Abstract
Awake tracheostomy in a child with respiratory distress is an emergency life-saving procedure when risk of airway loss after induction of general anaesthesia is greater due to difficult anatomy. A 10-year-old boy presented three days after removal of a foreign body in the throat under general anaesthesia. Over the subsequent days, the patient had a progressively increasing visible swelling in the neck, stridor and respiratory distress. An urgent X-ray and computed tomography scan of the neck revealed a retropharyngeal abscess compressing the trachea. Due to anticipated difficulty in airway management under general anaesthesia, we decided to perform an awake tracheostomy. The child and the parents were counselled regarding steps of awake tracheostomy, as well as the benefits and possible risks associated with it. Topicalisation was achieved by administering glycopyrrolate, nebulisation with lidocaine 4%, and the skin was prepared with lidocaine 2% with 1:200,000 adrenaline. After the awake tracheostomy was successfully performed, general anaesthesia was induced and the retropharyngeal abscess was drained. Effective communication and building rapport is essential for safe awake tracheostomy in a child with respiratory distress when impending airway loss may occur at any moment.

Abstract
OBJECTIVE To compare the oral microbiota of Sjögren's syndrome (SS) with that of healthy subjects (HS). METHODS Supragingival and subgingival biofilm samples were collected from the mesial-buccal tooth surfaces of SS patients (n = 57) and age- and sex-matched HS (n = 53). Unstimulated saliva and 8 oral tissue samples were taken using a buccal brush. Caries and periodontal measures were recorded. All supragingival samples and a subgroup of 24 SS and 28 HS subgingival samples, as well as 32 SS and 11 HS saliva and oral tissue samples, were analyzed for their content of 41 bacterial species using checkerboard DNA-DNA hybridization. Mean levels (×105 ± SEM) and percentage of DNA probe counts of each species were determined for each sample site and averaged within subjects in the 2 clinical groups. Kruskal-Wallis tests, adjusting for multiple comparisons and cluster analysis, were used for soft tissue and microbial analysis, and the Mann-Whitney test was used to compare caries and periodontal measures. RESULTS Mean (×105 ± SEM) total DNA probe counts in supragingival samples were significantly lower (P < 0.001) in the SS (13.3 ± .7) compared to the HS (44.1 ± 6.8) group. In supragingival samples, Veillonella parvula, Fusobacterium nucleatum ss vincenti, and Propionibacterium acnes were markedly elevated in the SS compared to the HS group in both mean (×105 ± SEM) and mean (± SEM) percentage DNA probe counts (P < 0.001). In subgingival samples of SS, V. parvula was significantly different compared to HS (P < 0.05). SS was characterized by high levels of purple and low levels of orange and red complexes. Cluster analysis of oral tissues and saliva demonstrated that the mean microbial profiles for SS patients and the HS group clustered separately. Active root caries (P < 0.003) and attachment loss were significantly higher (P < 0.029) in the SS group compared to the HS group. CONCLUSION These findings indicate that saliva is a major controlling factor of intraoral biofilm. V. parvula may be a unique microbial biomarker for Sjögren's syndrome. KNOWLEDGE TRANSFER STATEMENT The microbiome characterized for Sjögren's syndrome in salivary hypofunction is shown to be under stress and reduced. Veillonella parvula can be a possible identification of a biomarker for Sjögren's syndrome.

Abstract
Background:Inflammation is the forerunner to fibrosis and premature ageing in various systemic diseases. Hence it seems plausible that idiopathic inflammatory myopathies (IIM) may exhibit accelerated senescence too.Objectives:Hence we investigated the Myostatin: Follistatin system in the serum as a reflection of early senescence in myositis as compared with healthy and diseased controls.Methods:Patients with inflammatory myositis (ACR/EULAR criteria) presenting to the wards and outpatient clinic between December 2017 to August 2019 were recruited. Those with active infection, pregnancy, renal dysfunction or chronic kidney disease were excluded. Apart from patient and disease variables, activity and damage were assessed using standard IMACS score set measures. Patients in inception cohort were additionally followed up at 1 and 6 months. Myostatin and Follistatin were estimated in sera using ELISA (R&D systems, USA). Juvenile myositis and young adults (18-40 years) were subsequently analyzed separately. Non-parametric tests were used for paired and unpaired analysis. Results expressed as median.Results:95 myositis (8 Juvenile myositis, 26 DM, 10 PM, 29 Overlap, 2 NAM 1 CAM and 19 ASS) patients (23 Male and 72 Female) with median age 38 (24.5-46.0) years and disease duration 0.9 (2.3-5.1) years were included. Serum Myostatin was lower in IIM than in healthy control (HC) (153.5 vs. 243.6 p<0.0001, Fig 1A) but higher in IIM as compared with disease controls (153.5 vs 86.1 p=0.0174 Fig. 1B). Serum myostatin was comparable between juvenile and adult myositis and in the various subsets of adult myositis (Fig. 1 C and D). Myostatin levels were higher in active as compared with inactive myositis in young adults (211.7 vs. 158.9, p=0.0149, Figure 1E). Serum Myostatin correlated with height (r 0.3, p=0.003) and weight (r 0.2, p=0.047) but not MMT8 or muscle enzymes.Figure 1.Serum Myostatin levels in IIM as compared with healthy controls (A) and disease controls (B). Levels in juvenile myositis as compared with adult IIM (C) and in various subsets of IIM (D). Serum Myostatin levels in active and inactive disease (E).Although Follistatin was lower in IIM than HC (198.4 vs 243.6, p=<0.0001), the neither Follistatin nor Myostatin: Follistatin ratios differ between subsets, and in active versus inactive disease Figure 2 A-D). On follow-up, the serial Myostatin estimation paralleled change in disease activity.Figure 2.Serum Follistatin levels in IIM as compared with healthy controls (A) and disease controls (C). Levels in juvenile and adult IIM (D) and in various subsets of IIM (D).Conclusion:Elevated serum Myostatin levels in active myositis raise the possibility of accelerated senescence in the inflamed muscle tissues which need further investigation.Acknowledgments: :Partly funded by APLAR and IRA research grants awarded to LG.Disclosure of Interests:None declared
