Abstract
STATEMENT OF PROBLEM Evaluating the effectiveness of the management of Olfactory Dysfunction (OD) has been limited by a paucity of high-quality randomised and/or controlled trials. A major barrier is heterogeneity of outcomes in such studies. Core outcome sets (COS) -standardized sets of outcomes that should be measured/reported as determined by consensus-would help overcome this problem and facilitate future meta-analyses and/or systematic reviews (SRs). We set out to develop a COS for interventions for patients with OD. METHODS A long-list of potential outcomes was identified by a steering group utilising a literature review, thematic analysis of a wide range of stakeholders' views and systematic analysis of currently available Patient Reported Outcome Measures (PROMs). A subsequent e-Delphi process allowed patients and healthcare practitioners to individually rate the outcomes in terms of importance on a 9-point Likert scale. RESULTS After 2 rounds of the iterative eDelphi process, the initial outcomes were distilled down to a final COS including subjective questions (visual analogue scores, quantitative and qualitative), quality of life measures, psychophysical testing of smell, baseline psychophysical testing of taste, and presence of side effects along with the investigational medicine/device and patient's symptom log. CONCLUSIONS Inclusion of these core outcomes in future trials will increase the value of research on clinical interventions for OD. We include recommendations regarding the outcomes that should be measured, although future work will be required to further develop and revalidate existing outcome measures.

Abstract
BACKGROUND Locoregional failure is a unique and challenging problem in head and neck cancer with controversy surrounding the use of re-irradiation in the treatment. We aimed to evaluate the dosimetry and technical parameters in utilizing a collagen matrix with embedded Cesium-131 (Cs-131) radioactive isotope seeds as it relates to dose distribution and dose to carotid artery. METHODS AND MATERIALS Cadaveric feasibility study randomizing Cs-131 strands alone or Cs-131 with collagen matrix to be placed into neck dissection defects. For the dose computation, physicists employed the TG-43 dosimetry calculation algorithm with a point source assumption to compute the dose. Carotid arteries were contoured in MIM-Symphony software and the carotid artery maximum and mean doses were calculated in accordance with TG-43 specifications. Ease of use of collagen matrix tiles on a 7-point Likert scale and mean radiation dose to the carotid artery. RESULTS Ease of use score was higher in collagen matrix compared to stranded seeds with a mean score of 6.3 +/- 1.2 compared to 4.5 +/- 0.87. Time of implantation was statistically significantly, p = 0.031, lower in the collagen matrix group (M = 5.17 min, SD = 4.62) compared to stranded seeds (M = 15.83 min, SD = 3.24). Mean radiation dose to the carotid artery was 62.8 Gy +/- 9.46 in the collagen matrix group compared to 108.2 Gy +/- 55.6 in the traditional Cs-131 seeds group. CONCLUSIONS We present a feasibility and concept cadaveric study using a collagen matrix with Cesium-131 demonstrating preliminary evidence to support its ease of use, decreased time to implantation, and decreased dose delivered to the carotid artery.

Abstract
Aims Complementary medicine therapists such as traditional acupuncturists are a large resource for supporting public health targets to improve health behaviours. Our objectives were to determine the prevalence and patterns of UK acupuncturists’ provision of lifestyle change support, test theory-based hypotheses about facilitators and barriers to supporting lifestyle changes and to explore associated characteristics and attitudes. Methods A mixed methods design in which British Acupuncture Council members (Sept 2019-April 2020) completed an online questionnaire assessing prevalence of lifestyle change support, typical patterns across patients and behaviours, Theory of Planned Behaviour constructs, practitioner characteristics and open-text responses regarding additional behaviours and clinical decisions to introduce lifestyle change. Results Three hundred fifty-two traditional acupuncturists participated (Mean age = 51.5 years, SD 9.9; 81.8% (n = 288) female). 57.7% (n = 203) reported offering support for lifestyle change during their most recent consultation. 91.7% (n = 323) reported supporting lifestyle change ‘always or most of the time’ for patients with chronic conditions and 67.9% (n = 239) reported this for patients with acute conditions. The pattern of typical support for different health behaviours ranged from 44.6% (n = 157) for smoking reduction (acute conditions) to 95.2% (n = 335) for diet support (chronic conditions). A linear regression model found that frequency of support for lifestyle change in acute patients was predicted by acupuncturists’ attitudes to both clinical role and importance of health behaviours, confidence in their ability to provide lifestyle change support and use of fewer behaviour change techniques. The decision to first offer lifestyle change support was guided by perceived patient receptiveness, whether presenting condition/diagnosis were likely to improve with lifestyle change and whether a strong therapeutic relationship was established. Conclusions Traditional acupuncturists’ reports suggest their work supports key public health targets for promoting healthy behaviours. Less frequent support for alcohol/smoking may reflect user characteristics but may suggest training needs for acupuncturists. Increase could be made for support in acute presentations, however the importance of patient receptiveness, linking advice to condition, and therapeutic alliance should be explored further. There may be important differences between acupuncture practice and mainstream healthcare (e.g. high level of contact, longer visits, holistic approach) which impact mechanisms of action of behaviour change.

Abstract
BackgroundPrimary Sjögren’s syndrome (pSS) is a systemic rheumatic disease that affects several organ systems, most frequently the ocular, oral and musculoskeletal domains. Multidisciplinary care is thus crucial in the optimal management of SS patients.ObjectivesTo report the clinical impact of a Multidisciplinary SS Clinic (MSSC) over a 5-year period.MethodsWe prospectively included patients assessed in the MSSC from September 2015 to October 2020. All patients had a full clinical evaluation, including disease-related questionnaires, specialized oral/ocular assessment, salivary gland biopsy (SGB) and ultrasound (SGUS), tear and salivary flow and ocular staining scores. We compared the results of patient-reported outcomes, comprehensive clinical assessments and specialized complementary exams in patients with pSS and other diagnoses.Results445 patients (96% women, mean age 57±14 years) with sicca symptoms underwent complete multidisciplinary evaluation. Patients were most frequently referred from Rheumatology (91%), but also from Stomatology (5%), Ophthalmology (2%), Internal Medicine (1%) and other medical specialties (1%). Most patients were diagnosed with pSS (n=221; 50%), followed by non-Sjögren sicca syndrome (nSSS, n=134; 30%), secondary SS (sSS, n=60; 13%) and undifferentiated connective tissue disease (n=30; 7%). Positive sicca tests were present in 217/385 patients (56%): unstimulated whole salivary flow (UWSF) ≤0.1ml/min in 84/317 (27%); Schirmer’s test ≤5mm/5min in 163/354 (46%); van Bijsterveld score ≥4 in 42/349 (12%); Ocular Staining Score (OSS) ≥5 in 36/343 (11%). Subjective complaints assessed by the EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI), the EULAR Sicca Score (ESS), the Profile of Fatigue and Discomfort - Sicca Symptoms Inventory (PROFAD-SSI), the Xerostomia Inventory (XI), and the Ocular Surface Disease Index (OSDI) did not differ between patients with pSS and other diagnoses. However, objective dryness measures such as UWSF (31vs20%, p=0.028), Schirmer’s test (51vs40%, p=0.040) and OSS (14vs7%, p=0.048) were significantly associated with pSS. A positive SGB (focus score≥1) was seen in 48% of patients with a clinical diagnosis of pSS (p<0.001 vs. other diagnoses), with a mean focus score of 1.1±1.6. Instead, 94% of patients with nSSS had grade 0-1 biopsies. Mean SGUS scores (p=0.006) and the frequency of moderate/severe changes (p<0.001) were higher in pSS patients.ConclusionMultidisciplinary evaluation was crucial in the assessment of patients with similar sicca complaints and in the management of ocular/oral/systemic involvement. Objective measurements and specialized complementary exams greatly contribute to establishing or confirming the diagnosis of pSS.Disclosure of InterestsNone declared

Abstract
530 Background: TNBC is a highly complex, heterogenous disease associated with poor outcomes, high incidence of distant metastases, and limited treatment options. With the purpose of identify patients at different risk of distant recurrence, we developed a prognostic model using clinicopathological characteristics that contribute to the risk of recurrence in TNBC patients and also evaluate its influence in the time of beginning of adjuvant therapy. Methods: We retrospectively analyzed 687 TNBC patients who received adjuvant chemotherapy between January 2000 to December 2014 at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru). The database was randomly divided into two groups to create a discovery set (n = 344) and a validation set (n = 343). Univariate and multivariate Cox regression analysis was conducted to identify prognostic factors for distant recurrence-free survival (DRFS). We developed a linear risk score based on clinicopathologic characteristics. Under STEPP methodology we classified patients at high, intermediate or low-risk of distant recurrence and the absolute treatment effects of time to initiation of chemotherapy (TTC, ≤ 30 vs > 30 days) through risk subgroups was estimated. Results: The median of follow-up was 9.90 years. In total, 31.0% (n = 213/687) relapses were registered. Variables associated with DRFS in the multivariate analysis were: age, T-staging, and N-staging. A tumor staging of T3-T4 vs. T1/T2 (HR = 2.92, 95%CI: 1.39 - 6.17), followed by the number of positive lymph nodes (N2-N3 vs N0/N1; HR = 2.78, 95%CI: 1.74 - 4.45) and an older age (≥ 60 years vs. ≤ 40/41-59, HR = 2.66, 95%CI: 1.46 - 4.88) were the clinicopathologic characteristics contributing to a higher risk score according to the 3-variable model. Also, 3 risk groups were identified and corroborated in the validation group. In the discovery set, patients with a TTC > 30 days experienced an overall decreased of 17.5% (95%CI: 6.7 - 28.3) in 10-year DFRS vs. those who initiated adjuvant therapy before 30 days. The impact of TTC > 30 days was higher in patients classified as high-risk (Decreased 10-year DFRS: 53.3 ± 28.8 %), similar findings were found in the validation set. Conclusions: A prognostic model based in clinicopathological characteristics (age, pT and pN), was able to classify TNBC patients’ candidates to adjuvant chemotherapy in 3 prognostics groups. We identified a subgroup of patients in which delaying of adjuvant chemotherapy (> 30 days) confers very high-risk of relapse.

Abstract
Several clinical trials have demonstrated the benefit of adding pertuzumab to trastuzumab plus neoadjuvant chemotherapy in the treatment of human epidermal growth factor receptor 2 (HER2)-positive breast cancer. The comparison of outcomes between nonrandomized groups of patients who received similar treatments in routine practice remains difficult. The present study aimed to evaluate the pathological complete response (pCR) rates achieved with pertuzumab among patients in routine clinical care in Peru using real-world data. The definition of pCR used was the absence of residual invasive cancer from the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy. A total of 44 patients with non-metastatic HER2-positive breast cancer (stages II and III) treated with pertuzumab in the neoadjuvant setting and who underwent surgery at three private clinics in Lima (Peru) were retrospectively evaluated. The pCR was the efficacy endpoint and it was determined and compared with the results from other clinical trials. Furthermore, safety data were described. The median age was 44 years (interquartile range, 39.5-50.5 years) and 65.9% of patients were premenopausal. Regarding the clinical stage, 56.8% were IIA/IIB and 36.4% were IIIA/IIIB/IIIC. All treatment schemes included concurrent trastuzumab. The patients' treatment comprised neoadjuvant therapy of docetaxel/trastuzumab/pertuzumab (THP) with a median of 4 cycles in 30 patients (68.2%) or docetaxel/trastuzumab/pertuzumab/carboplatin (THPCarb) with a median of 6 cycles in 14 patients (31.8%). In total, 70.5% of patients experienced pCR; among hormone receptor-negative cases, 75.0% achieved pCR and in tumors expressing hormone receptors, the rate of pCR was 66.7%. Of those patients subjected to neoadjuvant treatment with THP, 66.7% (20/30) achieved pCR, whereas 78.6% (11/14) of patients who received THPCarb had a pCR. The incidence of drug-related adverse events was 59.1% and in none of the patients, administration was discontinued due to toxicity. The present results of Peruvian patients with HER2 breast cancer treated according to clinical routine demonstrated that dual blockade of HER2 with trastuzumab and pertuzumab in the neoadjuvant setting achieved high rates of pCR even in hormone receptor-positive patients. These results are consistent with those of randomized controlled trials, with a good safety profile.

Abstract
The pace of digital disruption over the past few years has been spectacular, transforming every sector of the economy, including animal production, health and welfare. This paper reviews some advanced digital technologies that may shape the future of Veterinary Services. These technologies are all data driven and are illustrated by three examples that fall under the following categories: a) wireless and mobile technologies for animal health monitoring, disease surveillance, reporting and information sharing; b) advanced data-processing technologies, such as big data and data analytics used to detect patterns, make predictions, find correlations and other information; and c) promising technologies such as blockchain applications, used for effective and efficient management of various input supply chains. The authors briefly discuss current challenges to increasing the use of these technologies in the animal health sector, along with some implications for Veterinary Services. Digital technologies will have a profound effect on how animal health services are delivered and how animal health systems are managed. It is therefore crucial for Veterinary Services to be proactive and adapt to the ongoing digital transformation. Investment in new technologies and preparing the current and future veterinary workforce with the necessary digital skills and knowledge to stay up to date and at the centre of digital innovation in animal health should be a priority for the years to come.

Of these P, 24 (80%) male and 6 (20%) female, 20 P were diagnosed myocardial infarction with ST-segment elevation, 2 P myocardial infarction non ST and 8 P with myocardial hypertrophy non ischemic. Of these P 30% were diabetics, 56% hypertension, 70% dyslipidemia, 36% smokers previous to CRP and body mass index 26,3 medium.
All P were submitted to previous echocardiogram, cardiopulmonary exercise testing (CET) and a rehabilitation program minimum 4 sessions and maximum 52 sessions. At the end of the total sessions the echocardiogram and CET were repeated.
Results
Of the 30 P that participated in CRP only 20 completed the program, while the other 10 P dropped out because of social and economic problems. Of the P that completed the CRP, 70% got better on EF, 80% improved VE/VCO2 slope < 33 therefore are classified VC-II in ventilatory classification (VC), 5% VE/VCO2 slope > 40 VC-III classification, and 15% maintained the initial classification. 50% of the P increased at least one level metabolic equivalent of task (MET) from the first CET. Only 3 of the 20 patients came, once, to the hospital after the CRP with heart failure, and one died but did not fulfill the program.
Conclusion
Patients with mid-range heart failure submitted to a CRP can improve cardiorespiratory predictors, leading to a better quality of life. However, it is important to find solutions to minimize the causes that make patients to give up CRP.

Abstract
Abstract
Background
The Hepatitis B virus (HBV) affects over 250 million people worldwide and can lead to cirrhosis and hepatocellular carcinoma. HBV surface antigen (HBsAg) quantification is increasingly used to predict disease activity and treatment response. As there is no virologic cure, clinicians are seeking a “functional cure”, or HBsAg loss, as a guide to safely stopping nucleos(t)ide analogue therapy. Tenofovir Disoproxil Fumarate (TDF) and Entecavir (ETV) are first line therapy but require prolonged treatment to achieve HBsAg clearance.
Aims
To assess the association between nucleos(t)ide therapy and decline in quantitative HBsAg (qHBsAg) in patients with HBV from Calgary, Alberta.
Methods
A retrospective review of adult patients with chronic HBV, followed at the University of Calgary Liver Clinic, was conducted between January 2012 and October 2020. Patients were excluded if treatment was discontinued or changed, only had a single qHBsAg measurement, or were co-infected with hepatitis C virus, hepatitis delta virus, or HIV. Patients were stratified according to therapy with TDF, ETV, or no treatment. To identify associations between mean changes in qHBsAg by medication exposure, one-way ANOVAs and t-tests were performed. Results were reported as means and 95% confidence intervals (CI). The median time from initial qHBsAg to most-recent was calculated.
Results
187 patients were included in the final analysis (Table 1). 77 were excluded for being on more than one medication over the study period, 10 were excluded due to discontinuation of treatment, and 195 were excluded for single qHBsAg measurements. The mean qHBsAg decline was -750.04 IU/mL (95% CI -1311.58, -188.50) in the TDF group (n=45) and -309.20 IU/mL (95% CI -600.90, -17.50) in the ETV group (n=35) (p=0.20). In the no treatment group (n=107), the mean qHBsAg increased by 711.29 IU/mL (95% CI -600.78, 2023.80)(Figure 1). The median time from initial qHBsAg to most-recent was 980 days.
Conclusions
Quantitative HBsAg levels declined in patients on TDF and ETV, but increased in untreated patients. Although HBsAg levels showed a trend for greater decline in TDF-treated patients, results failed to reach statistical significance, and may be affected by overall treatment duration. Future studies will explore medication use as a time-varying covariate to identify how change in treatment influences changes in HBsAg over time.

Abstract
Background Epidemiological studies commonly identify the clinical characteristics and survival outcomes of patients with breast cancer at five years. Our study aims to describe the sociodemographic, clinicopathological characteristics and determine the long-term event-free survival (EFS) and overall survival (OS) of a Peruvian population with triple-negative breast cancer. Methods We reviewed the medical records of new cases treated at a single institution in the period 2000–2014. The survival analysis included patients with stages I-IV. Survival estimates at 10 years were calculated with the Kaplan-Meier method and compared with the Log-rank test. We further used multivariate Cox regression analysis to calculate prognostic factors of recurrence and mortality. Results Among the 2007 patients included, the median age at diagnosis was 49 years (19–95 years). Most patients presented histologic grade III (68.7%), tumor stage II (34.2%), and III (51.0%) at diagnosis. Local and distant relapse was present in 31.9 and 51.4% of the patients, respectively. The most frequent sites of metastasis were the lungs (14.5%), followed by bone (9.7%), brain (9.6%), and liver (7.9%). The median follow-up was 153 months. At 3, 5, and 10 years, the EFS of the population was 55%, 49%, and 41%, respectively, while the OS was 64%, 56%, and 47%, respectively. Moreover, an N3 lymph node status was the most important prognostic factor for both disease relapse (HR: 2.54, 95% CI: 2.05–3.15) and mortality (HR: 2.51, 95% CI: 2.01–3.14) at ten years. An older age and higher T staging were associated with a worse OS, while patients who received radiotherapy and adjuvant chemotherapy had better survival rates. Conclusion The sociodemographic features of Peruvian patients with TNBC are similar to those of other populations. However, our population was diagnosed at more advanced clinical stages, and thus, EFS and OS were lower than international reports while prognostic factors were similar to previous studies.

Abstract
Although lymph node status (ypN) is one of the most important prognostic factors of survival, the lymph node ratio (LNR) has emerged as an equitable factor. We aimed to compare the prognostic value of both ypN and LNR in patients with residual triple-negative breast cancer (TNBC) after neo-adjuvant chemotherapy (NAC). This was a retrospective cohort study of patients treated in a tertiary care center during the period 2000-2014. We stratified the population based on LNR (≤0.20, 0.20-0.65, and >0.65) and ypN (N1, N2, and N3) status. The overall survival (OS) and progression-free survival (PFS) were estimated with Kaplan-Meier curves and the log-rank + test. We further compared patient mortality and disease recurrence using multivariate Cox regression analysis. We evaluated 169 patients with a median follow-up of 87 months. At 2 years of follow-up, patients with low-risk LNR compared to those with moderate and high risk had a higher PFS (54% vs 31% vs 18%, respectively; P < .001) and OS (74% vs 64% vs 45%, respectively; P < .001). Moreover, ypN1 patients compared to ypN2 and ypN3 showed similar results in PFS (53% vs 35% vs 19%, respectively; P = .001) and OS (73% vs 69% vs 43%, respectively; P < .001). Compared to the low-risk population, patients with moderate (hazard ratio [HR]: 3.50; 95% confidence interval [CI]: 1.41-8.71) and high risk (HR: 6.90; 95% CI: 2.29-20.77) had a worse PFS. Regarding OS, moderate-risk (HR: 2.85; 95% CI: 1.10-7.38) and high-risk patients (HR: 6.48; 95% CI: 2.13-19.76) showed considerably worse outcomes. On the other hand, ypN staging was not associated with PFS or OS in the multivariate analysis. The LNR is a better prognostic factor of survival than ypN. The LNR should be considered in the stratification of risk after NAC in patients with TNBC.

Abstract
e19258 Background: Immunotherapy has changed the landscape of cancer treatment. The aim of this work was to describe the adverse events related to immunotherapy treatment in diverse type of malignant tumors using real-world data. Methods: This is a retrospective review of patients with diverse type of advanced malignancies treated with immunotherapy at Oncosalud-AUNA (Lima-Peru) during the period 2016-2018. We present a descriptive analysis of the clinicopathological and treatment features of the patients, as well as data of safety of immunotherapeutic agents. Results: In total, 37 patients were included in the study. The median age was 67 years (38 to 84 years); 64.9% of patients were male; 54.1% were smoker/former smoker and 45.9% non-smokers. Regarding to the primary tumor, 75.7% were lung cancers (82.1%, adenocarcinomas and 17.9%, squamous cell carcinomas), 16.2% were melanomas, 5.4, head and neck cancers and 2.7%, were bladder cancers. Central nervous system metastases were present in 29.7% of patients. Immunotherapy was given after a first line in 43.2% of cases, 40.5% after the second line and 16.2%, after the third line of treatment. The types of immunotherapy were prembrolizumab in 54.1%, nivolumab in 40.5%, atezolizumab in 2.7% and avelumab in 2.7%. 27% of cases had combination of immuno with chemotherapy. Finally, regarding to adverse events, 94.6% had any adverse event; 48.6% fatigue and asthenia; 35.1%, nausea; 32.4, pruritus/rash; 27.7%, decreased appetite; 18.9%, hypo/hyperthyroidism; 13.5%, diarrhea/colitis; 10.8%, pneumonitis and 5.4%, infusion-related reactions. Conclusions: During the study period we had a slightly higher incidence of adverse events than reported by other works. It could be probably due to the age of patients and several prior lines of treatment.

Abstract
e17520 Background: To determine if there is association between the clinical-pathological characteristics and the development of bone metastases in patients with prostate cancer treated in Oncosalud during the period 2016-2018. Methods: An observational, analytical, cross-sectional and retrospective study was conducted in 386 men diagnosed with prostate cancer in a Private Clinic in Peru. We presented descriptive and analytic analysis to identify variables associated with bone metastases; in addition, odds ratios were estimated. Results: In reference to the PSA groups, those patients with PSA values higher than 20 ng / ml presented a risk 9.69 times higher to develop bone metastases (95% CI: 5.08-18.45). In regard to Gleason groups, those with a 9-10 score presented a risk of bone metastasis 2.67 times higher than patients with lower Gleason score (95% CI: 1.31-5.45). In regard to the clinical stage, those patients with a T3 stage had a 6.77 higher risk than those with lower clinical stages (95% CI: 3.79-12.09). Conclusions: Clinical-pathological characteristics associated with bone metastasis were identified in patients with prostate cancer, including age, Gleason scale, PSA value and clinical T stage.

Abstract
BACKGROUND Autism spectrum disorders (ASD) affect many children with an estimated prevalence of 1%. Array-comparative genomic hybridization (CGH) offers significant sensitivity for the identification of submicroscopic chromosomal abnormalities and it is one of the most used techniques in daily practice. The main objective of this study was to describe the usefulness of array-CGH in the etiologic diagnosis of ASD. METHODS Two-hundred fifty-three patients admitted to a neurogenetic outpatient clinic and diagnosed with ASD were selected for array-CGH (4 × 180K microarrays). Public databases were used for classification in accordance with the American College of Medical Genetics Standards and Guidelines. RESULTS About 3.56% (9/253) of copy number variations (CNVs) were classified as pathogenic. When likely pathogenic CNVs were considered, the rate increased to 11.46% (29/253). Some CNVs apparently not correlated to the ASD were also found. Considering a phenotype-genotype correlation, the patients were divided in two groups. One group according to previous literature includes all the CNVs related to ASDs (23 CNVs present in 22 children) and another with those apparently not related to ASD (10 CNVs present in 7 children). In 18 patients, a next-generation sequencing (NGS) panel were performed. From these, one pathogenic and 16 uncertain significance variants were identified. CONCLUSION The results of our study are in accordance with the literature, highlighting the relevance of array-CGH in the genetic of diagnosis of ASD population, namely when associated with other features. Our study also reinforces the need for complementarity between array-CGH and NGS panels or whole exome sequencing in the etiological diagnosis of ASD.

Abstract
Under the International Health Regulations (IHR, 2005), a legally binding document adopted by 196 States Parties, countries are required to develop their capacity to rapidly detect, assess, notify and respond to unusual health events of potential international concern. To support countries in monitoring and enhancing their capacities and complying with the IHR (2005), the World Health Organization (WHO) developed the IHR Monitoring and Evaluation Framework (IHR MEF). This framework comprises four complementary components: the State Party Annual Report, the Joint External Evaluation, after-action reviews and simulation exercises. The first two are used to review capacities and the second two to help to explore their functionality. The contribution of different disciplines, sectors, and areas of work, joining forces through a One Health approach, is essential for the implementation of the IHR (2005). Therefore, WHO, in partnership with the Food and Agriculture Organization of the United Nations (FAO), the World Organisation for Animal Health (OIE), and other international and national partners, has actively worked on facilitating the inclusion of the relevant sectors, in particular the animal health sector, in each of the four components of the IHR MEF. Other tools complement the IHR MEF, such as the WHO/OIE IHR-PVS [Performance of Veterinary Services] National Bridging Workshops, which facilitate the optimal use of the results of the IHR MEF and the OIE Performance of Veterinary Services Pathway and create an opportunity for stakeholders from animal health and human health services to work on the coordination of their efforts. The results of these various tools are used in countries' planning processes and are incorporated in their National Action Plan for Health Security to accelerate the implementation of IHR core capacities. The present article describes how One Health is incorporated in all components of the IHR MEF.

Abstract
The main mechanisms of antimicrobial resistance are described using the Vitek® 2 system in uropathogens isolated in older adults from a private clinic in Lima. Descriptive study conducted between January 2014 and October 2016. Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis obtained a sensitivity greater than 80% against piperacillin/ tazobactam, amikacin, and carbapenems. Moreover, 83.6% of Escherichia coli were nitrofurantoin-sensitive strains. A 41.7% of Escherichia coli, 50.9% of Klebsiella pneumoniae, and 50% of Proteus mirabilis were producers of extended spectrum beta-lactamases (ESBL). Similarly, 60% of Pseudomonas aeruginosa were producers of carbapenemases. Active site modification (PBP) and enzymatic inactivation by penicillinases occurred in 7.8% of Enterococcus faecalis. Resistance to aminoglycosides was presented in Escherichia coli (27.1%), Klebsiella pneumoniae (46.7%), and Proteus mirabilis (84.6%) for the production of modifier enzymes. There is an increase in bacterial resistance in relation to age. Enzymatic inactivation of beta-lactam antibiotics and aminoglycosides is the most common resistance mechanism.

Abstract
BACKGROUND The incremental shuttle walk test (ISWT) is one of the most widely used field tests to assess cardiorespiratory fitness in clinical and research settings. Reference equations to predict ISWT distance in different populations and age cohorts have been established. However, an equation for the Portuguese pediatric population is not available. This study aimed to develop a reference equation for predicting ISWT in Portuguese children and adolescents. METHOD Healthy children and adolescents aged between 5 and 17 years old were recruited. Sociodemographic (sex, age), anthropometric (height, weight) and physical activity (Physical Activity Index) data were collected. Lung function was assessed through spirometry and quadriceps muscular strength through hand-held dynamometry. The ISWT was performed twice. A reference equation was established with a multiple linear regression. RESULTS 130 (60 male; 13.66±2.61y) participants with normal lung function (forced expiratory volume in one second 102.73±15.09% predicted), body mass index (BMI) (20.27±3.59kg/m2) and quadriceps muscular strength (19.75±6.84kgf), completed the assessment. 50.8% (n=66) of the participants were moderately active. Participants walked on average 1165.08±327.19m in the ISWT. Sex, age and BMI were independent contributors to the ISWT, explaining 54% of its variability (p<0.001). The derived reference equation was: ISWT=342.06+(283.07×sex)+(83.61×age)-(22.22×BMI), with female=0 and male=1. CONCLUSION Sex, age and BMI were found to be contributors to the ISWT predictive equation for pediatric population, providing a simple reference to assess their cardiorespiratory fitness.

Abstract
OBJECTIVES To determine the rate of optimal cytoreduction in patients with advanced ovarian cancer who received neoadjuvant chemotherapy with dose-dense carboplatin and paclitaxel followed by interval debulking surgery (IDS). MATERIALS AND METHODS A retrospective study of a series of cases of Peruvian women treated with neoadjuvant chemotherapy with carboplatin (6 AUC mg/mL/min) and paclitaxel (80 mg/m2 weekly) followed by IDS, at the National Institute of Neoplastic Diseases during the 2010-2014 period. RESULTS The 41 patients who made it to the interval surgery had a median age of 59 years (range: 47-73 years). In 37 (90.2%) patients, high-grade serous adenocarcinoma histology was reported. Thirty-four (82.9%) achieved optimal cytoreduction and five (14.7%), a complete pathological response. Progression-free survival at one year and two years was 74.7% and 51.8%, respectively. Overall survival at one year and two years was 85.2% and 71.4%, respectively. The risk of progression and death was greater in patients without optimal cytoreduction and in patients with postsurgery levels of carcinoembryonic antigen 125 > 30 U/mL. CONCLUSIONS Neoadjuvant therapy with dose-dense carboplatin and paclitaxel achieved an elevated frequency of optimal cytoreduction. The post-surgery levels of carcinoembryonic antigen 125 and optimal cytoreduction were independent factors of progression-free survival and overall survival.

Abstract
Colorectal cancer (CRC) is one of the most common cancers in Latin America and the Caribbean, with the highest rates reported for Uruguay, Brazil and Argentina. We provide a global snapshot of the CRC patterns, how screening is performed, and compared/contrasted to the genetic profile of Lynch syndrome (LS) in the region. From the literature, we find that only nine (20%) of the Latin America and the Caribbean countries have developed guidelines for early detection of CRC, and also with a low adherence. We describe a genetic profile of LS, including a total of 2,685 suspected families, where confirmed LS ranged from 8% in Uruguay and Argentina to 60% in Peru. Among confirmed LS, path_MLH1 variants were most commonly identified in Peru (82%), Mexico (80%), Chile (60%), and path_MSH2/EPCAM variants were most frequently identified in Colombia (80%) and Argentina (47%). Path_MSH6 and path_PMS2 variants were less common, but they showed important presence in Brazil (15%) and Chile (10%), respectively. Important differences exist at identifying LS families in Latin American countries, where the spectrum of path_MLH1 and path_MSH2 variants are those most frequently identified. Our findings have an impact on the evaluation of the patients and their relatives at risk for LS, derived from the gene affected. Although the awareness of hereditary cancer and genetic testing has improved in the last decade, it is remains deficient, with 39%–80% of the families not being identified for LS among those who actually met both the clinical criteria for LS and showed MMR deficiency.

Abstract
The global community continues to incur the high costs of crisis mitigation and emergency response to outbreaks of emerging infectious diseases, such as those caused by the H5N1 highly pathogenic avian influenza virus, Ebola virus, Nipah virus, Zika virus or the Middle East respiratory syndrome coronavirus. These viruses are particularly dangerous in regions associated with poor development indicators and high vulnerability. The drivers of these disease crises include failures in the way that animal diseases are detected and reported and failures in the way in which disease response is implemented by animal health and public health systems. In addition, the lack of a coordinated response hampers disease control efforts. A comprehensive approach for disease prevention, detection and response, however, requires a coordinated and joint effort among governments, communities, donors and international networks to invest effectively in prevention systems that can identify early signals of the emergence, spillover and spread of animal pathogens at the local level. These signals include trade bans, market closures, civil unrest, heavy rains and droughts associated with climate change, and livestock intensification or changes in consumer behaviour. The global community needs to increase its investment in early warning and detection systems that can provide information that enables action to be taken at the national, regional and global levels in the event of an outbreak of a transboundary animal disease (TAD). Like any preventive measure, an early warning system requires financial resources, but these are insignificant when compared to the losses that are avoided. Building a global early warning and effective response system for outbreaks is value for money, as the benefits far outweigh the costs. The goal of the Food and Agriculture Organization of the United Nations (FAO) is to end hunger and poverty, which is a challenging and complex task. Building global capacity to prepare for and respond to TADs is an important element of the FAO's strategic objective to increase the resilience of livelihoods to threats and crises. Each year, livestock, and the people who rely upon them for their livelihoods, are confronted with animal disease and crises. They can strike suddenly, causing obvious illness and death, or emerge insidiously and become well established before becoming apparent. Animal disease emergencies threaten the production of, and access to, food; consequently, one of the FAO's missions is to help countries to prepare for and respond to animal health disasters.

Abstract
Sensitive techniques for the detection of Plasmodium (Aconoidasida: Plasmodiidae) sporozoites in field-collected malaria vectors are essential for the correct assessment of risk for malaria transmission. A real-time polymerase chain reaction (RT-PCR) protocol targeting Plasmodium mtDNA proved to be much more sensitive in detecting sporozoites in mosquitoes than the widely used enzyme-linked immunosorbent assay targeting Plasmodium circumsporozoite protein (CSP-ELISA). However, because of the relatively high costs associated with equipment and reagents, RT-PCRs are mostly used to assess the outcomes of experimental infections in the frame of research experiments, rather than in routine monitoring of mosquito infection in the field. The present authors developed a novel mtDNA-based nested PCR protocol, modified from a loop-mediated isothermal amplification (LAMP) assay for Plasmodium recognition in human blood samples, and compared its performance with that of routinely used CSP-ELISAs in field-collected Anopheles coluzzii (Diptera: Culicidae) samples. The nested PCR showed 1.4-fold higher sensitivity than the CSP-ELISA. However, nested PCR results obtained in two laboratories and in different replicates within the same laboratory were not 100% consistent, probably because the copy number of amplifiable Plasmodium mtDNA was close in some specimens to the threshold of nested PCR sensitivity. This implies that Plasmodium-positive specimens should be confirmed by a second nested PCR to avoid false positives. Overall, the results emphasize the need to use molecular approaches to obtain accurate estimates of the actual level of Plasmodium circulation within malaria vector populations.

Abstract
Abstract
Background: Metastatic triple-negative breast cancer (mTNBC) is a heterogeneous disease with poor prognosis where recent studies suggest that the immune system plays a critical role the mechanisms of disease progression and metastasis. In the other hand, a high Neutrophil to Lymphocyte Ratio (NLR) is associated with poor survival in patients diagnosed with several types of cancer. Our aim was to evaluate the prognostic value of NLR in mTNBC.
Methods: We retrospectively reviewed 130 patients diagnosed with mTNBC between 2000-2014 at “Instituto Nacional de Enfermedades Neoplasicas”. NLR group was divided in <2.5 and ≥2.5. Sites of metastasis were identified by TAC or magnetic resonance imaging. Survival rates were estimated by the Kaplan-Meier method and differences were calculated by Log-rank test. The Cox Regression was used for prognostic factors.
Results: The median age was 50 years (range: 23-92 years). From our study population, 41.2% were premenopausal, and just 10 patients (9.5%) had a breast-ovary cancer familiar background, 62.5% were diagnosed at clinical stage T3-T4 and 86.1% had lymph node involvement. From 130 patients, 41 and 64 had NLR <2.5 and ≥2.5, respectively, while there was no association between characteristics and NLR, only patients with malnutrition had NLR ≥2.5 (9.1% vs 40.8%, p=0.002) and solid organ involvement (62.4% vs 81.3%, p=0.04). Furthermore, lung and bone were the most frequent sites of metastasis. Those patients with lower ratio (<2.5) had better response to chemotherapy (p <0.001). With a median follow-up of 6.25 years, at 1-year OS was lower among patients with NLR ≥2.5 (59% vs 20%, HR: 2.77, 95%CI:1.77-4.33, p<0.001). In addition, at univariate analysis malnutrition also showed an impact on OS (HR: 1.79, 95%CI: 1.20-2.67, p=0.005). At multivariate analysis, between age, T stage, N stage, NLR and solid organ involvement, just NLR was the best and only predictor of worse OS (HR: 3.12, 95%CI:1.94-5.03, p<0.001).
Conclusion: In mTNBC, an NLR ≥2.5 was a strong and accessible biomarker of poor OS. Lower values of NLR could help us to predict chemotherapy response.

Abstract
Abstract
Background: Triple negative breast cancer (TNBC) patients with residual disease are characterized for a bad outcome. In these patients nodal involvement after neoadjuvant chemotherapy (NAC) is one of the most important prognostic determinants. In this study we compare two prognostic variables based on nodal status, the lymph node ratio (LNR=#positive nodes/#resected nodes) and residual lymph node status (ypN) in TNBC who received NAC.
Methods: We evaluated a retrospective cohort of TNBC patients with residual disease in the lymph nodes (at least 4 resected nodes) and treated with NAC between 2000-2014 at the Instituto Nacional de Enfermedades Neoplasicas (Lima-Peru). Patients were grouped in three LNR groups (≤0.20, 0.20-0.69 and ≥0.70). Survival differences were calculated by the log rank test. Prognostic factors for progression free survival (PFS) and overall survival (OS) were assessed by the Cox regression analysis.
Results: Overall, 189 were evaluated. Mean age was 48y (range: 26-73) where 53.5% were premenopausal and 16.5% had breast/ovary cancer familial background. A total of 175 pts (92.6%) had clinical T3-T4 tumors and 85.2% had nodal involvement at diagnosis. Indeed, the majority of patients had III CS (94.2%). Regarding to the LNR, 48.2% (n=91), 29.6% (n=56) and 22.2% (n=42) (22.2) had LNR ≤0.20, 0.21-0.69 and ≥0.70, respectively. Distribution of clinical differences was similar between groups, except for the clinical N stage (N2-N3: 15.4%, 46.4%, 52,3%, respectively; p<0.001). The median follow-up was 7 years. Progression risk was higher in patients with LNR ≤0.20 than 0.20-0.69 and ≥0.70 (HR=1.77, 95%CI:1.21-2.59, p=0.003 and HR=2.22, 95%CI:1.47-3.35, respectively, p<0.001). It was similar for the risk of death (HR=1.78, 95%CI: 1.17-2.70, p=0.007 and HR=2.95, 95%CI:1.91-4.56, respectively, p<0.001). LNR groups were associated to progression events (P=0.02) in contrast to ypN groups (P=0.07). In the multivariate analysis, pre-menopausal status, a higher LNR and ypT with non-complete response were prognostic factors of worse DFS. Only a higher LNR has a negative impact on OS (table 1).
Conclusion: LNR was an independent prognostic factor for TNBC in patients with residual disease with better capability than ypN to predict progression events. LNR should be considered in the risk stratification after NAC among these patients.

Abstract
Abstract
Background: The incidence of breast cancer (BC) is low in young women and is characterized by a high prevalence of triple-negative tumors, representing a group of high risk. In this work, we describe the clinicopathological and epidemiological features of triple-negative breast cancer (TNBC) in patients aged ≤35 years.
Methods: We reviewed information of TNBC patients diagnosed at ≤35 years old and treated at the Instituto Nacional de Enfermedades Neoplasicas (between 2000 and 2014). The Cox proportional hazard model was used to identify prognostics factors for DFS and OS.
Results: In total, of 243 out 2007 cases (12.11%) were very young TNBC patients. The median follow-up was 9 years. The median age was 32 years (range: 19-35); 14.8% had obesity. A total of 40 (16.5%) patients had a family history of breast-ovary cancer (FHBOC). Regarding to the clinical-pathological characteristics, 59.4% presented T-Stages 3/4; 65.2% had nodal involvement and 7 patients (2.9%) had bilateral BC. Most of patients were diagnosed at Clinical Stage (CS) III (50.8%). The most common histological subtype the was ductal invasive carcinoma (92.1%), followed by medullar (4.5%) and lobulillar (1.7%). A high histological grade was frequent (84.7%), while 71 cases (49%) were diagnosed with vascular permeation and 55 (48.2%) with macrometastasis in lymph nodes. The majority of patients underwent mastectomy (60.2%) compared to lumpectomy (39.8%). Locoregional relapse and distant metastasis were reported in 30.9% and 49.4% of cases, respectively. The most frequent sites of metastases were lung (14.8%) and brain (11.5%). In the multivariate analysis, only N3 stage was associated with a poor outcome in terms of (N0 vs N3, HR=7.89, 95%CI:2.76-22.56, p<0.001). Variables associated with the risk of death were N stage (P<0.001 for N0 vs N3), neoadjuvant chemotherapy (P<0.027), adjuvant chemotherapy (P<0.001), and radiotherapy (P=0.008).
Conclusions: TNBC in very young Peruvian women was characterized by advanced stage at diagnosis. In these patients, nodal involvement was the most important prognostic factor for DFS. It presents distinctive characteristics and poorer outcomes in terms of DFS and OS.

Abstract
Abstract
Background: Although chemotherapy is not recommended in low-risk early breast cancer, triple-negative breast cancers (TNBC) have twice risk of recurrence despite an aggressive treatment. In this study we evaluated the role of chemotherapy in the outcome of T1N0 TNBC patients in terms of disease-free survival (DFS) and overall survival (OS).
Methods: We evaluated a retrospective cohort T1N0 TNBC patients diagnosed between 2000 to 2014 at the Instituto Nacional de Enfermedades Neoplasicas (Lima-Peru). Survival rates differences were assessed by Log-rank test and prognostic factors were identified using the Cox proportional hazards model.
Results: We identified 123 T1N0 TNBC patients. The median age was 51 years (range: 28-85), where 38.5% were premenopausal. Thirty-six (29.3%) were pT1a/b and 87 were pT1c (70.7%). ACT was administered more frequently in pT1c patients (74.7% vs 55.6%; P=0.036). Locoregional relapse and distant metastases rates were 8.3% vs 19.5% and 5.6% vs 16.1% for tumors pT1a/b and pT1c, respectively. The median of follow-up was 8.8 years. Independent prognostic factors were pT stage and treatment with ACT. In relation to pT stage, DFS rates were 97% vs 78% (at 5-years) and 97% vs 70% (at 8-years) for pT1a/b vs pT1c patients, respectively (HR=4.8; 95%CI:1.46-17.0; P=0.015). In the other hand, patients treated with ACT had a better outcome with DFS rates to 5-years of 86% vs 74% and 8-years of 81% vs 65% (HR: 0.41, 95%CI: 0.17-0.97, p=0.043). Our study had not statistical power to evaluate benefit of ACT in pT1a/b patients. In cases with pT1c tumors, treatment with ACT was the only factor associated with a better DFS (HR=0.29, 95%CI: 0.11-0.77, p=0.012). Because the low mortality in our cohort, OS was not evaluable.
Conclusions: Treatment with adjuvant chemotherapy reduces the recurrence risk in 71% among pT1cN0 TNBC.

Abstract
Abstract
Background: Triple-negative breast cancer (TNBC) is characterized by being a heterogeneous disease with different risk factors and poor survival rates. TNBC have a higher prevalence in the Peruvian population (21.3%) than in Caucasian groups. Our study aims to determine the outcome and identify prognostic factors in Peruvian women with TNBC.
Methods: We retrospectively analyzed TNBC patients treated at the “Instituto Nacional de Enfermedades Neoplasicas” between 2000 and 2014. Survival rates and differences were calculated by the Kaplan-Meier method and Log-rank test, respectively. With the Cox regression, in univariate and multivariate analysis, we identified prognostic factors in for our TNBC population.
Results: In total, 2007 patients were diagnosed.The mean age was 50 years (range: 19-95 years); 44.8% were premenopausal and 26.2% had obesity at diagnosis. A family history of breast and/or ovarian cancer was present in 266 (28.9%) patients. Regarding the clinical-pathological features, 1860 (93.5%) had ductal invasive carcinoma and 1024 (51.6%) patients were in Stage (S) III. Local relapse and distant metastasis affected to 34.5% and 51.4% of our patients, respectively. Lung (14.5%) and bone (9.7%) were the most frequent sites of metastasis. The median follow-up was 9 years. The 5 and 10 yrs DFS/OS rates are shown in table 1. In the multivariate analysis, adjuvant chemotherapy (ACT) (HR: 0.60, 95%CI: 0.44-0.82, p=0.001) and radiotherapy (RT) (HR:0.72, 95%CI:0.55-0.93, p=0.014) were associated with a reduced risk of recurrence, while nodal involvement were associated to a high recurrence risk. Factors associated to a reduction in the risk of death were ACT (HR:0.73, 95%CI:0.61-0.88, p=0.001), RT (HR: 0.70, 95%CI: 0.60-0.92, p<0.001), and Neoadjuvant CT (HR: 0.61, 95%CI: 0.51-0.73, p<0.001); in contrast, a NLR≥3 (HR:1.60,95%CI: 1.36-1.87, p<0.001), N stage were associated with a higher risk of death.
Conclusions: Sociodemographic features of Peruvian patients with TNBC resemble other populations; however, our population is diagnosed at more advanced clinical stages, hence DFS and OS were lower than international reports while prognostic factors were similar to previous studies.

Abstract
The H-scan analysis of ultrasound images is a matched-filter approach derived from analysis of scattering from incident pulses in the form of Gaussian-weighted Hermite polynomial functions. This framework is applied in a preliminary study of thyroid lesions to examine the H-scan outputs for three categories: normal thyroid, benign lesions, and cancerous lesions within a total group size of 46 patients. In addition, phantoms comprised of spherical scatterers are analyzed to establish independent reference values for comparison. The results demonstrate a small but significant difference in some measures of the H-scan channel outputs between the different groups.
