Abstract
PURPOSE/OBJECTIVE(S) This study aimed to identify the impact of the pandemic on radiotherapy activity among members with cancer. MATERIALS/METHODS This retrospective study included fully-insured commercial members of a large national payor with cancer aged ≥18 years undergoing radiotherapy from March 1, 2018 to February 28, 2022. Radiotherapy activity was defined as the mean weekly number of treatment courses and attendances (fractions) per month pre-COVID (March 2018 to February 2020); during COVID (March 2020 to February 2021); and post-COVID (March 2021 to February 2022). T-tests assessed differences between pre-COVID and post-COVID on radiotherapy activity by age, gender, and cancer type. Interrupted time series analysis (ITS) assessed change in activity overtime, controlling for pre-COVID trends and other potential confounders. A p-value of <0.05 was considered significant. RESULTS The study included 9,275 members, 10,121 courses, and 169,257 fractions; most members were female (57%), the mean age was 57 years (SD = 12). Overall, there was a decline in mean weekly number of courses from the pre-COVID to post-COVID (-18%, p<0.05) timeframe. Females < 70 years experienced the largest decline in mean weekly number of courses (-23%, p<0.05) followed by males aged 70+ (-16%, p<0.05) and males < 70 years (-16%, p<0.05). All cancer types saw a significant decline (p<0.05); breast cancer reported the largest decline (-21%, p<0.05). Fraction numbers significantly declined overall by 27% (p<0.05) from the pre-COVID to post-COVID timeframe. The largest decline in fraction numbers was observed in females < 70 (-28%, p<0.05) followed by males < 70 years (-24%, p<0.05) and males aged 70+ (-22%, p<0.05). No difference between COVID and pre-COVID weeks for courses was observed once pre-COVID trends were accounted for using ITS. Females aged 70+ received 25% (p<0.05) fewer fractions during COVID compared to pre-COVID; a decline which continued to grow even as the pandemic eased (March 2021 to February 2022). Males aged 70+ also experienced a decreased level of fractions during the pandemic (-30%, p<0.05), but increased in the recovery period (+24%, p<0.05). Males < 70 years had an increased level of fractions during the pandemic (+14%, p<0.05). CONCLUSION Radiation mean weekly number of courses and fractions between pre-COVID and post-COVID declined with the effect more pronounced in females < 70 years. A decrease in fraction number was observed in all cancer types; specifically, breast cancer had the largest decline. ITS analysis revealed no difference between COVID and pre-COVID weeks for courses as the downward trend was already present prior to the pandemic. These findings suggest while radiotherapy courses and fractions were significantly impacted, fractionation was decreased to a greater extent, indicating an increased adoption of hypofractionation during the pandemic.

Abstract
STUDY QUESTION What is the present performance of artificial intelligence (AI) decision support during embryo selection compared to the standard embryo selection by embryologists? SUMMARY ANSWER AI consistently outperformed the clinical teams in all the studies focused on embryo morphology and clinical outcome prediction during embryo selection assessment. WHAT IS KNOWN ALREADY The ART success rate is ∼30%, with a worrying trend of increasing female age correlating with considerably worse results. As such, there have been ongoing efforts to address this low success rate through the development of new technologies. With the advent of AI, there is potential for machine learning to be applied in such a manner that areas limited by human subjectivity, such as embryo selection, can be enhanced through increased objectivity. Given the potential of AI to improve IVF success rates, it remains crucial to review the performance between AI and embryologists during embryo selection. STUDY DESIGN SIZE DURATION The search was done across PubMed, EMBASE, Ovid Medline, and IEEE Xplore from 1 June 2005 up to and including 7 January 2022. Included articles were also restricted to those written in English. Search terms utilized across all databases for the study were: ('Artificial intelligence' OR 'Machine Learning' OR 'Deep learning' OR 'Neural network') AND ('IVF' OR 'in vitro fertili*' OR 'assisted reproductive techn*' OR 'embryo'), where the character '*' refers the search engine to include any auto completion of the search term. PARTICIPANTS/MATERIALS SETTING METHODS A literature search was conducted for literature relating to AI applications to IVF. Primary outcomes of interest were accuracy, sensitivity, and specificity of the embryo morphology grade assessments and the likelihood of clinical outcomes, such as clinical pregnancy after IVF treatments. Risk of bias was assessed using the Modified Down and Black Checklist. MAIN RESULTS AND THE ROLE OF CHANCE Twenty articles were included in this review. There was no specific embryo assessment day across the studies-Day 1 until Day 5/6 of embryo development was investigated. The types of input for training AI algorithms were images and time-lapse (10/20), clinical information (6/20), and both images and clinical information (4/20). Each AI model demonstrated promise when compared to an embryologist's visual assessment. On average, the models predicted the likelihood of successful clinical pregnancy with greater accuracy than clinical embryologists, signifying greater reliability when compared to human prediction. The AI models performed at a median accuracy of 75.5% (range 59-94%) on predicting embryo morphology grade. The correct prediction (Ground Truth) was defined through the use of embryo images according to post embryologists' assessment following local respective guidelines. Using blind test datasets, the embryologists' accuracy prediction was 65.4% (range 47-75%) with the same ground truth provided by the original local respective assessment. Similarly, AI models had a median accuracy of 77.8% (range 68-90%) in predicting clinical pregnancy through the use of patient clinical treatment information compared to 64% (range 58-76%) when performed by embryologists. When both images/time-lapse and clinical information inputs were combined, the median accuracy by the AI models was higher at 81.5% (range 67-98%), while clinical embryologists had a median accuracy of 51% (range 43-59%). LIMITATIONS REASONS FOR CAUTION The findings of this review are based on studies that have not been prospectively evaluated in a clinical setting. Additionally, a fair comparison of all the studies were deemed unfeasible owing to the heterogeneity of the studies, development of the AI models, database employed and the study design and quality. WIDER IMPLICATIONS OF THE FINDINGS AI provides considerable promise to the IVF field and embryo selection. However, there needs to be a shift in developers' perception of the clinical outcome from successful implantation towards ongoing pregnancy or live birth. Additionally, existing models focus on locally generated databases and many lack external validation. STUDY FUNDING/COMPETING INTERESTS This study was funded by Monash Data Future Institute. All authors have no conflicts of interest to declare. REGISTRATION NUMBER CRD42021256333.

Abstract
Abstract
Study question
Does the supplementation of vitamin B12 protect the spermatozoa against damage caused by the freeze-thaw process further improving the overall post-thaw survival and DNA integrity?
Summary answer
The antioxidant property of vitamin B12 protects the spermatozoa and improves the post thaw motility, vitality, and reduces DNA damage caused by freeze-thaw process.
What is known already
Cryopreservation of spermatozoa is an effective way of fertility preservation in humans, often used in Assisted Reproductive Technology(ART). Despite the refinement in cryopreservation, the salvage of post-thaw sperms remains poor. The reactive oxygen species(ROS), that is formed as a result of freeze-thaw process is known to decrease the motility, plasma membrane integrity and increase the DNA fragmentation. Most vitamins have antioxidant properties, that protect the mammalian cells from oxidative stress one such vitamin is cyanocobalamin(vitamin B12). Vitamin B12 modulates oxidative stress through methionine synthase activity and also acts as a scavenger of ROS. Thus protecting the DNA against free radicals.
Study design, size, duration
This prospective observational study was performed for a period of 6 months in 111 men, who attended the fertility clinic. The study population included all semen samples except men with azoospermia, surgically retrieved samples and men on vitamin supplements. The study population contained men ageing between 21-40 years.
Participants/materials, setting, methods
Semen samples were analysed according to WHO 5th edition and were assessed for DNA fragmentation index (DFI) using sperm chromatin dispersion assay (SCD). The ejaculates were split into two as group A: semen samples with equal amount of cryoprotectant and group B: semen samples with equal amount of cryoprotectant supplemented with Vitamin B12 (2mg/ml). They were frozen for a minimum of 24 hrs. Post-thaw motility, vitality and DFI were assessed and compared.
Main results and the role of chance
The mean age of patients in our study was 34.26±4.7yrs. 58.5% of the study population had primary infertility. 37.8% of the study population had male factor infertility, 32.4% had oligoasthenoteratozoospermia(OAT), 31.1% had normozoospermia 16.2% had asthenoteratozoospermia, 13.5% had teratozoospermia, 3.6% had oligozoospermia and rest 2.7% had asthenozoospermia.
There was an overall increase in post thaw motility (41.59±18.09 vs 32.3±18.8,p=0.0005), progressive motility (21.54±13.02 vs 15.91±11.80,p=0.0005), vitality (57.14±15.09 vs 46.76±16.45,p=0.0005) and a significant decrease in DFI (26.69±10.03 vs 32.09±10.00,p=0.0005) in group B compared to group A.
Our study also demonstrated that, Normozoospermia patients had a significant increase in vitality (67.17±13.8 vs 58.51±12.0, p = 0.007) and lower DFI (22.68±9.3 vs 27.6±8.9, p = 0.02) in group B than in group A.
OAT patients had a significant increase in total motility (26.25±12.15 vs 15.7±11.4,p=0.0003), progressive motility (11.69±8.8 vs 6.14±5.8,p=0.0028), vitality (46.06±11.34 vs 34.31±12.99,p=0.0001) and significantly lower DFI (30.22±9.87 vs 36.08±9.7,p=0.012) in group B.
Teratozoospermia patients showed significant increase in progressive motility in group B (27.87±8.81 vs 19.33±10.69,p=0.02) and
Asthenoteratozoospermia patients showed significant increase in total motility (40.72± 13.14 vs 30.89±13.06,p=0.02) and vitality (54.39±12.28 vs 43.78±14.14,p=0.02) in group B.
However, in asthenozoospermic patients the parameters were comparable in both the groups.
Limitations, reasons for caution
Due to ethical reasons the samples were not used for in vitro procedures such as intrauterine insemination(IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection(ICSI). Hence, no inference was obtained regarding the fertilization rates/ pregnancy rates.
Wider implications of the findings
Our study demonstrated that with supplementation of vitamin B12 the recovery rate significantly increased and also preserved the DNA content. Among the various categories, supplementation of vitamin B12 to OAT samples was more beneficial as it improved the overall viability of the sperms.

Abstract
BACKGROUND: TB diagnosis in patients with HIV is challenging due to the lower sensitivities across tests. Molecular tests are preferred and the Xpert® MTB/RIF assay has limitations in lower-income settings. We evaluated the performance of loop-mediated isothermal amplification (LAMP) and the lipoarabinomannan (LAM) test in HIV-positive, ART-naïve clinic patients.METHODS: A total of 783 eligible patients were enrolled; three spot sputum samples of 646 patients were tested using TB-LAMP, Xpert, smear microscopy and culture, while 649 patients had TB-LAM testing. Sensitivity, specificity, and negative and positive predictive values were estimated with 95% confidence intervals.RESULTS: Sensitivities for smear microscopy, TB-LAMP and Xpert were respectively 50%, 63% and 74% compared to culture, with specificities of respectively 99.2%, 98.5% and 97.5%. An additional eight were positive on TB-LAM alone. Seventy TB patients (9%) were detected using standard-of-care testing, an additional 27 (3%) were detected using study testing. Treatment was initiated in 57/70 (81%) clinic patients, but only in 56% (57/97) of all those with positive TB tests; 4/8 multidrug-resistant samples were detected using Xpert.CONCLUSION: TB diagnostics continue to miss cases in this high-burden setting. TB-LAMP was more sensitive than smear microscopy, and if followed by culture and drug susceptibility testing as required, can diagnose TB in HIV-positive patients. TB-LAM is a useful add-in test and both tests at the point-of-care would maximise yield.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA) accounts for significant mortality and morbidity worldwide. A limited but emerging literature has revealed increased risk of sudden cardiac death in patients with OSA. There is paucity of data on arrhythmia burden in patients with OSA, particularly in hospitalized patients.
Purpose
Therefore, we sought to study the prevalence of atrial and ventricular arrhythmias among hospitalized patients with OSA and examine its impact on sudden cardiac death and in-hospital mortality.
Methods
All patients over 18 years of age with OSA were extracted from the National Inpatient Sample (NIS) from 2009–10 using 9th revision of International Classification of Diseases (ICD-9) code 327.23. Demographic data, hospital characteristics, comorbid conditions, and arrhythmia burden including different types of arrhythmia were identified. Clinical outcomes were in-hospital mortality, length of stay and sudden cardiac death. Logistic regression analysis was performed to determine the impact of arrhythmia on in-hospital mortality in patients with OSA. Hospital level discharge weights provided by NIS were used to obtain national estimates of OSA hospitalizations.
Results
OSA was prevalent in 2.8% (n=1,114,297) of all hospitalizations among which 20.1% had any arrhythmia (n=223,974). Patients with arrhythmia were older, more likely to be males, and had higher prevalence of risk factors and comorbid conditions except for chronic liver disease, and smoking (p<0.0001 for all). Arrhythmia burden analysis revealed increase prevalence of both atrial and ventricular arrhythmia in patients with OSA compared to general population. In-hospital mortality (3.48% vs 1.27%; p<0.0001), length of hospital stay (6.4±0.1 vs 5±0.1; p<0.001) and sudden cardiac death (1.34% vs 0.4%; p<0.0001) were higher in OSA patients with arrhythmia compared to OSA patients without arrhythmia. Presence of arrhythmia in OSA patients was associated with increased in-hospital mortality in both unadjusted [OR 2.79 (2.62–2.98); p<0.001] and multivariable model adjusted for all risk factors and comorbid conditions [OR 1.83 (1.69–1.98); p<0.001].
Conclusion
Arrhythmia burden was higher in patients with OSA compared to the general population. Presence of arrhythmia among OSA patients was independently associated with increased in-hospital mortality and longer hospital stays. Routine evaluation to assess arrhythmia burden in patients in OSA could be a potential target to decrease sudden cardiac death in this high risk population.

Abstract
Abstract
Study question
Is the performance of the postwash total motile sperm count a predictor of pregnancy at the time of intrauterine insemination?
Summary answer
The number of motile spermatozoa inseminated (NMSI) in IUI can be used to define clear range of pre /postwash sperm parameters.
What is known already
There is no consensus about the optimal number of motile spermatozoa inseminated (NMSI) required for a reasonable chance of pregnancy after IUI. A meta-analysis of 16 studies assessing NMSI and IUI outcomes, concluded that at cut-off levels between 0.8 and 5 million, defined as the ability to predict failure to become pregnant. The purpose of this study is to determine the range of NMSI as a predictor of success in IUI.
Study design, size, duration
This prospective study includes 60 patients who underwent semen analysis at an academic infertility centre (SRIHER) during the month of December 2020 and January 2021.
Participants/materials, setting, methods
A total of 60 infertile couples who underwent IUI at our academic centre were enrolled in our study. A detailed history and infertility work up was done before proceeding for IUI, as per the department protocol. The semen was prepared by discontinuous 2 layered density gradient method. The results were analyzed by patient factors including age, BMI, semen parameters, NMSI. The NMSI were divided into 4 groups: A (<1), B (1–4), C (5–9), D (>10).
Main results and the role of chance
The mean age of the infertile couples who underwent IUI was (28.2 ± 3.8) in females and (31.8 ± 3.8) in males respectively. The sperm parameters such as concentration (21.8 ± 14.8), motility (53.15 ± 13.22), morphology (2.43 ± 1.33) respectively. When the NMSI was group C (5–9 x 10 6) the pregnancy rate was 38.5% whereas the pregnancy rate was 37.5% in group D ( >10 x 10 6). In the other sub groups such as group A(<1 x 10 6) and group C (1–4 x 10 6) the pregnancy rate was 14.2% and 12.5% respectively.
Limitations, reasons for caution
Infertile men with Azoospermia, Men with Retrograde ejaculation, Testicular samples, Epididymal samples, Infected samples. All of the above samples were avoided. It cannot be used for counselling during the initial infertility workup, but only during/after the IUI procedure.
Wider implications of the findings: The results suggest that NMSI can be a predictor of success in IUI in patients who are < 30 years of age & ≥35 years, NMSI does not appear to be a useful. The effect of NMSI on pregnancy rate needs to evaluated on a larger scale .

Abstract
Trilaciclib is an intravenous CDK4/6 inhibitor administered prior to chemotherapy to preserve haematopoietic stem and progenitor cells and immune system function from chemotherapy-induced damage (myelopreservation). The effects of administering trilaciclib prior to carboplatin, etoposide and atezolizumab (E/P/A) were evaluated in a randomised, double-blind, placebo-controlled Phase II study in patients with newly diagnosed extensive-stage small cell lung cancer (ES-SCLC) (NCT03041311). The primary endpoints were duration of severe neutropenia (SN; defined as absolute neutrophil count <0.5 × 109 cells per L) in Cycle 1 and occurrence of SN during the treatment period. Other endpoints were prespecified to assess the effects of trilaciclib on additional measures of myelopreservation, patient-reported outcomes, antitumour efficacy and safety. Fifty-two patients received trilaciclib prior to E/P/A and 53 patients received placebo. Compared to placebo, administration of trilaciclib resulted in statistically significant decreases in the mean duration of SN in Cycle 1 (0 vs 4 days; P < .0001) and occurrence of SN (1.9% vs 49.1%; P < .0001), with additional improvements in red blood cell and platelet measures and health-related quality of life (HRQoL). Trilaciclib was well tolerated, with fewer grade ≥3 adverse events compared with placebo, primarily due to less high-grade haematological toxicity. Antitumour efficacy outcomes were comparable. Administration of trilaciclib vs placebo generated more newly expanded peripheral T-cell clones (P = .019), with significantly greater expansion among patients with an antitumour response to E/P/A (P = .002). Compared with placebo, trilaciclib administered prior to E/P/A improved patients' experience of receiving treatment for ES-SCLC, as shown by reduced myelosuppression, and improved HRQoL and safety profiles.

Abstract
Introduction Current classification systems are not sure where to place the internet use disorder. Is it an addiction, an impulse control disorder, a consequence of another psychiatric morbidity or a consequence of personality trait/personality disorder? Objectives We intended to study which personality traits associated with online cognition may contribute towards Problematic internet use(PIU). We also analysed the relationship between number of hours of use/week of internet and PIU along with its relation with two ‘screening’ questions. Methods Online cognition scale and Abbreviated Eysenck Personality questionnaires were our measurements of choice in addition to demographic measures and some questions pertaining to online behaviour patterns. Results Total 163 responses were analysed. The demographic pools consisted mostly of young adults who had, on average, used the internet for 5.2 years at present rate of 21.81hours/week. We observed significantly higher mean OCS scores in men, in people who thought that the internet interfered with their lives and in those who felt the need to ‘cut-down’. A moderate positive and significant correlation was observed between hpurs/week of internet use and OCS scores. Also, significant positive correlation was observed between Neuroticism and OCS, impulsivity, and loneliness/depression scores. Significant negative correlations were observed between the Lie trait and impulse control. Neuroticism and Lie together contributed to 21.8% of variance in OCS scores. Conclusions Neuroticism and Lie traits (representing need for social acceptance) were found to the causing significamn varience in the OCS scores of the subjects. High number of hours/week use of internet was related to the feeling of ‘need to cut down use’.

Abstract
In this chapter, we describe the gastrointestinal side effects of oesophagectomy, gastrectomy and pancreaticoduodenectomy for cancer, with a focus on long-term functional impairments and their management. Improvements in upper gastrointestinal cancer surgery have led to a growing group of long-term survivors. The invasive nature of these surgeries profoundly alters the upper gastrointestinal anatomy, with lasting implications for long-term function, and how these impairments may be treated. Successfully maintaining a high quality of survivorship requires multidisciplinary approach, with survivorship care plans focused on function as much as the detection of recurrence.

Abstract
BACKGROUND Postoperative pancreatic fistulae (POPF) are a major contributing factor to pancreatoduodenectomy-associated morbidity. Established risk calculators mostly rely on subjective or intraoperative assessments. We hypothesized that various objective preoperatively determined computed tomography (CT) measurements could predict POPF as well as validated models and allow for more informed operative consent in high-risk patients. METHODS Patients undergoing elective pancreatoduodenectomies between January 2013 and April 2018 were identified in a prospective database. Comparative statistical analyses and multivariable logistic regression models were generated to predict POPF development. Model performance was tested with receiver operating characteristics (ROC) curves. Pancreatic neck attenuation (Hounsfield units) was measured in triplicate by pancreatic protocol CT (venous phase, coronal plane) anterior to the portal vein. A pancreatic density index (PDI) was created to adjust for differences in contrast timing by dividing the mean of these measurements by the portal vein attenuation. Total areas of subcutaneous fat and skeletal muscle were calculated at the L3 vertebral level on axial CT. Pancreatic duct (PD) diameter was determined by CT. RESULTS In the study period 220 patients had elective pancreatoduodenectomies with 35 (16%) developing a POPF of any grade. Multivariable regression analysis revealed that demographics (age, sex, and race) were not associated with POPF, yet patients resected for pancreatic adenocarcinoma or chronic pancreatitis were less likely to develop a POPF (10 vs. 24%; p = 0.004). ROC curves were created using various combinations of gland texture, body mass index, skeletal muscle index, sarcopenia, PDI, PD diameter, and subcutaneous fat area indexed for height (SFI). A model replacing gland texture with SFI and PDI (AUC 0.844) had similar predictive performance as the established model (p = 0.169). CONCLUSION A combination of preoperative objective CT measurements can adequately predict POPF and is comparable to established models relying on subjective intraoperative variables. Validation in a larger dataset would allow for better preoperative stratification of high-risk patients and improve informed consent among this patient population.

Abstract
Background:While several outcome measures have been studied for use in clinical studies of psoriatic arthritis, little is known about thresholds of meaning such as minimal clinically important improvement (MCII).Objectives:To investigate the distribution of scores for candidate outcome measures for pragmatic trials in PsA and to calculate the MCII for each outcome measure.Methods:We performed a longitudinal cohort study within the Psoriatic Arthritis Research Consortium (PARC), a multi-center study based in the US. Patients completed validated PROs (patient reported outcomes) and rheumatologists completed skin, joint, enthesis and dactylitis scores at therapy initiation and follow up 12-16 weeks later. In addition, patients completed a global assessment of response at the follow up visit, categorizing their status as improved, stayed the same, or worsened and then ratied the importance of the change on a scale from 0-7.1We then calculated and plotted the change in each of the following measures: Routine Assessment of Patient Index Data (RAPID3), clinical Disease Activity of Psoriatic Arthritis (cDAPSA), Patient Reported Outcome Measure Information System (PROMIS) Global Health short form (10a) physical health (PH) subscore, patient pain assessment, patient global assessment (0-10 NRS), and physician global assessments (0-10 NRS) of the joints and overall. We calculated the MCII as the mean change in score (with 95% confidence interval) among patients who reported improvement and rated the level of improvement as “almost none/hardly at all” or “a little important.” Additionally, we calculated Spearman’s correlation coefficients between the measures and the global assessment of response.Results:Among 148 unique patients, 233 therapy change visits were eligible for analysis. The average age was 52.5 years, 52% were female and mean BMI was 29.6. Baseline RAPID3 was 11.1 (SD 6), cDAPSA 17.9 (SD 13.9), PROMIS PH 42 (SD 8), patient global 4.2 (SD 2.5), TJC 5.9 (SD 7.5), and SJC 2.9 (SD 4.5). TNFi comprised 61% of drug initiations, 21% were IL17i and the remainder were other biologics and oral systemic therapies. At follow up, 63 (27%) patients rated themselves as improved whereas 103 (44%) stayed the same and 67 (29%) reported worsening. The mean change in each measure by patient-reported response (improved, stayed the same, or worsened) are shown in Figures 1A & B. In general, the mean score increased from ‘improved’ to ‘worsened’ as expected (with the exception of PROMIS PH which declines given a different direction of scoring). The MCII for each measure was as follows: RAPID3 -1.8 (-4.1 to 0.5), Patient Global -0.6 (-1.6 to 0.4), Physician Global -1 (-1.9 to -0.1), cDAPSA -5.7 (-9.8 to -1.7), and PROMIS PH 1.9 (-2.1 to 5.8). Correlation for each measure with the global assessment of response were: RAPID3 0.48, Patient Global 0.37, Physician Global 0.39, cDAPSA 0.51, and PROMIS PH 0.39.Figure 1A. Distribution of change (median, IQR) in RAPID3, Physician Global, Patient Global, PROMIS10a physical therapy by patient reported response.Conclusion:This is the first study to test thresholds of meaning for these particular measures in PsA. The MCII values are relatively low for all outcome measures. This may be related to the relatively low disease activity at baseline but is consistent with patients seen in clinical practice initiating therapy.2References:[1]Ward MM et al.

Abstract
9623 Background: The Lung Cancer Master Protocol (Lung-MAP) is designed to evaluate novel targeted therapies in patients with advanced squamous lung carcinoma. In the S1400F sub-study (non-match), we tested whether combined CTLA-4 and PD-1 inhibition with durvalumab plus tremelimumab (D+T) could overcome primary or acquired resistance to anti-PD-(L)1 therapy. Response, progression-free (PFS) and overall survival, and safety in the acquired resistance cohort are reported herein. Methods: Patients with previously treated squamous lung carcinoma, performance status (PS) 0-1, and adequate organ function that developed disease progression after ≥24 weeks of anti-PD-(L)1 monotherapy were eligible. Prior severe immune-related toxicities, intervening systemic therapy and combination chemo-immunotherapy were not permitted. Patients received D1500 mg + T75 mg IV q28 days for 4 cycles then D maintenance until disease progression. The primary endpoint was best objective response (RECIST 1.1). Interim analysis for futility was planned after 20 patients evaluable for response were enrolled. If no responses were observed, the cohort would stop enrolment. Results: 30 eligible patients were accrued to the acquired resistance cohort. Median age was 68 years, 60% of patients were male, 33% PS 0 and had received a median of 2 prior lines of therapy (maximum 4). Best response to prior anti-PD-(L)1 therapy was CR/PR/SD in 3/7/20 patients, with a median duration of anti-PD-(L)1 therapy of 8.6 months (5.2-30.4). No objective responses were seen with D+T; 47% had SD as best response. Median PFS was 2.0 months (95% CI 1.6-2.9) and survival 7.5 months (95% CI 5.3-8.7). Among the 14 patients with SD as best response, the median PFS calculated from first disease assessment is 2.8 months (95% CI: 1.4-3.9). Grade≥3 adverse events at least possibly related to protocol therapy were seen in 10/30 patients. These include 1 treatment-related death due to pneumonitis and 1 death not otherwise specified. Other adverse events include grade 3 confusion (1), dehydration (2), diarrhea (3), encephalopathy (1), weakness (1), hyperglycemia (1), hypoxia (1), lymphopenia (1), nausea, (1), neutropenia (1), thrombocytopenia (1), rash (1), vomiting (1), grade 4 dyspnea (1), leucopenia (1) and lymphopenia (1). Conclusions: D+T did not demonstrate activity in patients with acquired resistance to PD-1 checkpoint inhibitors and pretreated advanced squamous lung carcinoma. Clinical trial information: NCT03373760 .

Abstract
BACKGROUND It is well established that chronic exposure to tobacco induces head and neck cancers but the exact etiopathogenesis is not known. Though studies have shown expression of TIMP1, EPS8 and AXL in cancers, their role in tobacco-induced cancers is not known. We aimed this study to evaluate the role of these molecules in oral and oropharyngeal squamous cell cancers (SCC). MATERIALS AND METHODS In this single institutional study, 31 patients of oral and oropharyngeal SCC with history of chewing tobacco were included. Smokers were excluded from the study. After informed consent biopsies were taken from affected and contralateral normal mucosa. Paraffin blocks were made and tissue microarray (TMA) were constructed using these blocks. Immunohistochemistry (IHC) for TIMP1, EPS8, AXL kinase was carried out on these tissue microarrays. The intensity of staining was scored from 0 to 3+, related to expression of each of the three molecules. RESULTS The expression of TIMP1, EPS8 and AXL kinase was significantly more in the cancerous mucosa versus non-cancerous mucosa (P = 0.000 in all three) in oral and oropharyngeal SCC exposed to chewing tobacco. CONCLUSION Immunohistochemical expression of these molecular markers in oral and oropharyngeal SCC correlated with their molecular based studies. Significant IHC expression of TIMP1, EPS8 and AXL establishes their role in the pathogenesis of oral and oropharyngeal squamous cell carcinomas. Novel targeted therapies may be researched that can detect and target these molecules at an earlier stage of pathogenesis of these tumors.

Abstract
PURPOSE In the phase 3 KEYNOTE-407 study, the addition of pembrolizumab to carboplatin-paclitaxel/nab-paclitaxel significantly improved overall survival, progression-free survival, and objective response rate in patients with previously untreated metastatic squamous non-small-cell lung cancer (NSCLC), with little impact on severe toxicity. We present patient-reported outcomes (PROs) from KEYNOTE-407. METHODS Patients were randomly assigned to receive 4 cycles of pembrolizumab 200 mg or placebo once every 3 weeks plus carboplatin plus paclitaxel or nab-paclitaxel, followed by pembrolizumab or placebo for an additional 31 cycles. Health-related quality of life (HRQoL) was evaluated using the European Organisation for Research and Treatment of Cancer Treatment of Cancer Quality of Life Questionnaire-Core 30 (QLQ-C30) and Quality of Life Questionnaire-Lung Cancer Module 13 (QLQ-LC13). Key PRO endpoints were change from baseline to weeks 9 and 18 (during and after platinum therapy) in the QLQ-C30 global health status/quality of life (GHS/QoL) score and time to deterioration in the composite endpoint of cough, chest pain, or dyspnea from the QLQ-C30 and QLQ-LC13. Two-sided, nominal P values are provided. RESULTS A total of 554 and 553 patients completed ≥ 1 QLQ-C30 or ≥ 1 QLQ-LC13 assessment, respectively. GHS/QoL score improved for the pembrolizumab-combination group (least squares [LS] mean [95% CI] change from baseline: week 9, 1.8 [-0.9 to 4.4]; week 18, 4.3 [1.7 to 6.9]) and deteriorated in the placebo-combination group (week 9, -1.8 [-4.4 to 0.7]; week 18, -0.57 [-3.3 to 2.2]). Between-group differences were improved for the pembrolizumab-combination group (difference in LS mean scores: week 9, 3.6 [95% CI, 0.3 to 6.9], nominal P = .0337; week 18, 4.9 [1.4 to 8.3], nominal P = .0060). Median time to deterioration in cough, chest pain, or dyspnea was not reached in either group (hazard ratio, 0.79; 95% CI, 0.58 to 1.06]; nominal P = .125). CONCLUSION Addition of pembrolizumab to chemotherapy maintained or improved HRQoL measurements relative to baseline and improved HRQoL versus chemotherapy alone at weeks 9 and 18. These results support use of pembrolizumab plus chemotherapy as first-line therapy for metastatic squamous NSCLC.

Abstract
OBJECTIVE To evaluate the feasibility and safety of robotic-assisted breast-axillo insufflation thyroidectomy (RABIT) for differentiated thyroid cancer. METHODS In this retrospective case series, patients with differentiated thyroid carcinoma were enrolled in our hospital from January 2018 to December 2018. All patients underwent indirect laryngoscopy to assess the status of vocal cord preoperatively. RABIT was performed with five separate breast-axillo incisions. All the procedures were performed using da Vinci Xi Robotic Surgical System, a single docking method using CO2 insufflation. RESULTS Twelve patients completed RABIT, in which one case needed conversion to open thyroidectomy. The mean age was 30.25 ± 7 with male to female ratio being 1:1. Preoperative diagnosis showed papillary carcinoma (n = 9) and follicular neoplasm (n = 3). The mean operative time for RABIT was 140 ± 50.45 min and average blood loss during surgery was 22.92 ± 9 mL. Mean hospital stay was 4.42 ± 1.08 days. Final pathology confirmed classical papillary thyroid carcinoma (n = 10; 83.3%) and follicular variant of papillary carcinoma (n = 2; 16.7%). None of the cases reported injury or paralysis to the recurrent laryngeal nerves. CONCLUSION RABIT is a safe and feasible approach for thyroidectomy. It has several advantages in that it provides similar symmetrical view to conventional open surgery and enables to maintain specimen integrity and use of assistant port permits better handling of the gland. Additionally, the largest operating angles with this technique prevent collision between the robotic arms and provide excellent cosmetic satisfaction due to very small, five separate breast-axillo incisions.

Abstract
Abstract
Background
Systolic time intervals (STI) measured using Transthoracic Echo (TTE) have been shown to be sensitive indicators of contractile performance, but TTE is limited to a hospital setting. Recent advances in technology have enabled the simultaneous measurement of Electrocardiograms (ECG) and Seismocardiograms (SCG) using wearable devices. However, the use SCG to measure STIs has not been validated in a mobile setting, or on pathological subjects.
Purpose
To test the validity of an automated algorithm for measuring STIs using a wearable device recording ECG and SCG, in subjects with varying degrees of left ventricular dysfunction.
Methods
179 Patients with suspected left ventricular dysfunction were assessed using TTE performed by a Cardiologist. Patients were simultaneously fitted with a novel wearable device worn on a chest strap, recording SCG and single-lead ECG data, while the cardiologist measured the pre-ejection period (PEP) and left ventricular ejection time (LVET) with the patient in a supine position. Of these subjects 29 (16.2%) were diagnosed with Dilated cardiomyopathy (DCM), and 109 (60.8%) had Ischemic Heart disease.
The SCG and ECG data recorded on the wearable device was then analysed using a peak-detection algorithm, which detected the Q,R,S points on the ECG, and then determined the 4 most prominent peaks in the SCG signal corresponding to each R-peak. Heart rate, patient's age, gender and SCG time intervals were then used in a DecisionTree algorithm to determine the values of PEP and LVET, which were were then compared against those determined by the cardiologist using TTE.
Results
The correlation coefficient (r2) between PEP calculated using TTE, and the values obtained from the algorithm analyzing SCG data was 0.92 while the mean error was 7.47%. The r2 between the LVET calculated using the TTE and the algorithm was 0.75, while the mean error was 8.53% (p-value<0.001 for all cases).
Results All Subjects With IHD Without IHD With DCM Without DCM Number of Subjects 178 109 69 29 149 PEP (r2) 0.92 0.89 0.94 0.88 0.91 PEP (% age error) 7.47 7.50 7.42 6.99 7.56 LVET (r2) 0.75 0.81 0.66 0.55 0.83 LVET (% age error) 8.53 6.69 11.4 20.42 6.16 DCM, Dilate Cardiomyopathy; IHD, Ischemic Heart Disease.
ECG + SCG signals for a DCM patient
Conclusion
The algorithm-derived STIs measured by SCG correlate well with those measured by TTE across most patient groups, including those with Dilated Cardiomyopathy and Ischemic Heart Disease, opening prospects for continuous remote monitoring of STIs in a mobile setting.
