Abstract
Purpose This study examines the outcomes of locally advanced head and neck squamous cell carcinoma (HNSCC) following the adoption of conventional intensity-modulated radiotherapy (cIMRT) and volumetric-modulated arc therapy (VMAT) over a decade. The region under study has higher comorbidities associated with increased HNSCC incidence and poorer prognosis. Materials and methods A 10-year retrospective review of electronic medical records included 296 patients with stage III, IVA, and IVB HNSCC (American Joint Committee on Cancer, Seventh edition). Survival outcomes were compared between VMAT and cIMRT using Kaplan-Meier survival curves and adjusted for relevant demographic factors using Cox's proportional hazards model. Analysis was performed using R software (R Foundation, Vienna, Austria). Results The median age of the cohort was 63 years, comprising of 80% males. The oropharynx was the most common primary tumor site. 264 (89%) received 50Gy or higher dose radiation by either cIMRT (22%) or VMAT (67%). At five years, locoregional control (LC) and overall survival (OS) rates were 79.5% and 56.7%, respectively. VMAT showed a significant improvement in five-year OS (63.4% versus 43.8% for cIMRT, p=0.0023) but no significant difference in five-year LC (81% VMAT versus 74.5% cIMRT, p=0.17). Grade 3-4 acute toxicity was observed in 22% of patients. Conclusions VMAT and cIMRT demonstrated excellent LC in locally advanced HNSCC despite high comorbidity rates. Notably, VMAT was associated with significantly better OS compared to cIMRT. These outcomes surpass historical data, suggesting that VMAT technology may lead to improved patient outcomes. However, larger randomized controlled trials and dosimetric studies are needed to confirm these findings.

Abstract
Patient experience is globally recognized as an important indicator of health system performance, linked to health system quality and improving patient outcomes. Post COVID-19, health systems have embraced digital health and advanced digital transformation efforts; however, the relationship between digital health and patient experience outcomes is not well-documented. Using HCAHPS hospital survey data to measure patient experience, and HIMSS EMRAM Maturity Model data to measure digital maturity, a cross-sectional design using multivariate analyses examined the impact of digital maturity on patient experience in US hospitals. Our analysis shows that advanced digital maturity in US hospitals is associated with stronger patient experience outcomes, particularly relative to communication with nurses, doctors, and communication about medicines and therapies. The findings suggest that there are significant differences in patient experience associated with teaching versus nonteaching hospitals, urban versus rural hospitals. As hospitals advance and progress digital transformation initiatives, evidence to inform how transformation efforts can engage and advance patient experience will contribute to health system performance well into the future.

Punchhi G, Hussein A, Kulkarni S. Real-world survival outcomes of immunotherapy for advanced non-small cell lung cancer: A single-center retrospective review. Thorac Cancer 2024; 15:394-401. [PMID: 38239043 PMCID: PMC10864119 DOI: 10.1111/1759-7714.15205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/07/2023] [Accepted: 12/09/2023] [Indexed: 02/15/2024] Open
Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is often diagnosed at an advanced stage. Clinical trials have demonstrated that first-line immunotherapy alone or in combination with chemotherapy improves overall survival. However, reports of survival outcomes in real-world settings are limited. We assessed survival in advanced NSCLC patients treated with immunotherapy alone or in combination with chemotherapy in first- or second-line at the Windsor Regional Cancer Program (WRCP) and compared it to existing literature. METHODS We included patients diagnosed with stage IV NSCLC from January 2015 to December 2020 and treated with first-line chemoimmunotherapy (ChemoImmuno1), chemotherapy followed by immunotherapy (Chemo1), or immunotherapy followed by chemotherapy (Immno1) in our survival analysis. Patients with oncogene-addicted mutations were excluded. RESULTS There were 160 patients of which 41.5% were female. Mean age was 68 years. Median overall survival from time of diagnosis was 474 days (95% CI: 249, 949) with an estimated 5-year survival of 11.1% (95% CI: 4.5, 21.3). Median OS in ChemoImmuno1 was 9.6 months, in Chemo1 was 19.2 months from time of diagnosis and 10.5 months from time of initiation of immunotherapy, and in Immuno1 was 18.4 months, respectively. Estimated survival at three years from time of diagnosis for ChemoImmuno1 was 17.6% and for Immuno1 was 17.9%. For Chemo1, from diagnosis it was 20.1% and from second-line therapy it was 15.4%. Survival outcomes were comparable to clinical trials and other studies. CONCLUSION Real-world survival outcomes of immunotherapy for advanced NSCLC are comparable to the existing literature in this single center study.

Abstract
OBJECTIVE Oxidative stress represents a ruthless complication of β-thalassemia that worsens the severity of that medical condition. There is no conclusive evidence on the best antioxidant used for that issue. Our earlier clinical study concluded that omega-3 and Manuka honey add-on to the conventional therapy had a potential therapeutic impact on reducing oxidative stress. However, there is no research evaluating their cost-effectiveness. This paper compares the cost-effectiveness of Omega-3 and Manuka honey supplementation to conventional therapy in treating oxidative stress among children with β-thalassemia major. SUBJECTS AND METHODS Cost-effectiveness evaluation of daily supplementation of Omega-3-Manuka honey and Manuka honey alone to the conventional therapy was performed. The economic evaluation was performed on data from a prospective 10-month randomized clinical trial. Fifty patients were recruited into the Omega-3-Manuka honey plus conventional therapy group, 50 patients were included in the Manuka honey alone plus conventional therapy group, and 50 patients receiving the conventional therapy alone served as a control group. Effectiveness measures from the randomized clinical trial were used to determine incremental effectiveness. Cost estimates were calculated from the healthcare payer's perspective. The analysis considered the improvement in oxidative stress biomarkers presented here as a percent change from baseline to determine the incremental effectiveness and cost for the treatment by both interventions. RESULTS Adding Omega-3 or Manuka honey to conventional therapy was a more cost-effective add-on than conventional treatment alone. Omega-3-Manuka honey was more cost-effective than Manuka honey alone in treating oxidative stress in that condition. Oxidative stress biomarkers were significantly reduced with both experimental medications compared to the conventional therapy alone. CONCLUSIONS The present study showed that using Manuka honey and Omega-3 as add-on treatments for oxidative stress in pediatric β-thalassemia disease could have significant cost-saving and clinical improvement.

Abstract
The thyroid hormones play a crucial role in regulating various physiological processes in the human body. They have a wide range of effects that impact metabolism, growth, development, and overall homeostasis. The current study aimed to investigate the levels of HbA1c and various biomarkers in different patient groups. Two groups of patients were included in the study, each consisting of 30 patients, encompassing both genders. One group comprised patients with type 2 diabetes mellitus (T2DM) who were receiving insulin treatment, while the other group comprised patients with T2DM who were not receiving insulin treatment. These patient groups were compared to a control group of participants from both genders. The research employed the colourimetric method to measure HbA1c levels in all groups. Additionally, they utilized the Enzyme-Linked Immunosorbent Assay (ELISA) method to measure the levels of insulin, and T4 in all groups. The study also involved comparing these biomarkers between groups and examining the effect of insulin levels on thyroid hormones. The mean±SD values were 4.4867±1.02 µg/dl and 3.2367± 0.78 µg/dl for the T2DM groups with and without insulin treatment, respectively, while it was 7.9033±0.29 µg/dl in the control group. These findings provide valuable insights into the relationship between insulin levels and thyroid hormones, shedding light on the complex interplay between these two physiological systems. Overall, the impact of insulin on thyroid hormone regulation underscores the intricate interplay between endocrine systems and highlights the need for a comprehensive understanding of these interactions to optimize patient care and improve health outcomes.

Abstract
In the context of diabetes mellitus (DM), anti-glutamic acid decarboxylase (antiGAD) antibodies are associated with a specific form of the disease called type 1 diabetes. The study aims to evaluate the serum cortisol and serotonin levels in patients with type 2 DM disease. A total of 90 Iraqi participants (30 with type 1 diabetes mellitus, 30 with type 2 diabetes mellitus and 30 healthy subjects as a control group) were enrolled in the study. Blood samples were collected, serum separated, and frozen for future analysis. The level of Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) was measured for each person who participated in this study (whether DM diseases or control individuals) and AntiGAD (anti-glutamic acid decarboxylase). The study examined the descriptive statistics of HOMA-IR and AntiGAD levels in individuals with different types of diabetes. The results showed that individuals with type 1 diabetes mellitus (T1DM) had a significantly lower HOMA-IR compared to the control group, while individuals with type 2 diabetes mellitus (T2DM) had a significantly higher HOMA-IR. The study also found that both T1DM and T2DM groups had significantly elevated levels of AntiGAD compared to the control group. These findings suggest that insulin resistance is reduced in T1DM individuals but increased in T2DM individuals, and the presence of diabetes is associated with increased levels of AntiGAD. In summary, the results of this study demonstrate significant differences in both HOMA-IR and AntiGAD levels between individuals with diabetes (T1DM and T2DM) and the control group. These findings contribute to our understanding of the pathophysiology of diabetes and highlight the importance of these biomarkers in the diagnosis and management of the disease. Further research is needed to explore the underlying mechanisms behind these observations and to determine their clinical implications.

Abstract
Our study aimed to evaluate the level of coenzyme (CoQ10) in the plasma of human which suffered from beta-thalassemic major disease and vitamin E concentration in comparison to control cases. We included 90 (60 β-TM patients and 30 persons for control groups). The range of age (15-40 years) during the period from December 2022 to March 2023, and the study included patients previously diagnosed with beta-thalassemia major from Medical City and Karama Hospital. The level of serum CoQ10 in the patients was 2.02 ng/ml and in the control, groups were 3.55 ng/ml. The difference was statically high between the two groups (P<0.001). Likewise, our study includes the concentration of vitamin E in the study groups (patients 2.29 ng/ml and for control cases 7.25 ng/ml). The results highlight that there was a highly significant difference between the two groups (P<0.001). In conclusion, for both β-TM patients and control groups, the results show that the two parameters CoQ10 and vitamin E were highly significant difference((P<0.001) which means there were lower antioxidant capacities as demonstrated by the results of our new study.

Abstract
Kidney failure, also known as end-stage kidney disease, is a medical condition in which the kidneys are functioning at less than 15% of normal. Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney failure, which develops slowly. Diagnosis of chronic failure is based on a glomerular filtration rate (GFR) of less than 15 or the need for renal replacement therapy. It is also equivalent to stage 5 chronic kidney disease.The study aimed to evaluate the role of MPO and Co Q10 in different stages of CKD, and correlates this parameter with urea, Cr, Na, K, and eGFR.A Case-control study is carried out in Baghdad in the Imamian Kadhimian Medical City and Al-Karamah Teaching Hospital between August 2022 and March 2023. The number of CKD males under study were 60 male whose ages were between 25 to 50 years old. In addition, the control group consisted of 30 healthy volunteer males aged between 25 to 50 years and they did not have any diseases. Blood samples were collected from each male for measurement of Myeloperoxidase (MPO), and Coenzyme Q10 by Enzyme-linked immunosorbent assay (ELISA). The study showed that the reduced mean level of myeloperoxidase (p<0.001) in the patient's group compared with the control group, (19.9±6.82 ng/ml) and (42.4±4.98 ng/ml) respectively. Our study revealed that with increasing CKD stage, the myeloperoxidase levels decrease. Also, the reduced mean level of Coenzyme Q10 was 2.97±0.511 ng/ml in the patient group was highly significant than the control group's 7.07±2.41 ng/ml (p<0.001). Our study revealed that with increasing CKD stage, the coenzyme Q10 levels decrease. The study found a positive correlation of serum myeloperoxidase with coenzyme Q10 in CKD patients.

Abstract
Ischemic heart disease, also called coronary artery disease (CAD), is the term given to heart problems caused by narrowed heart (coronary) arteries that supply blood to the heart muscle.The study aims to determine the levels of Von Willebrand factor in patients with coronary artery disease.A total of 60 CAD patients and 30 healthy individuals were enrolled in the present study. Blood was withdrawn and serum was separated for measurement of lipid profile, human von Willebrand Factor, and lactate dehydrogenase (LDH).The study demonstrated that the highest mean of VWF was observed among IHD patients (81.75±29.75 ng/ml) and the lowest mean was within the control group (26.53±5.12 ng/ml). The differences were highly significant (P=0.0001). The study showed that the highest means of cholesterol, triglyceride, and LDL and the lowest mean of HDL were detected in IHD patients as compared with the healthy control group. The study showed that the mean of VWF was (88.76 ng/ml) in patients with hypertension which were significantly highest than in non-hypertensive IHD patients (75.76 ng/ml) at P=0.043. The study showed that the highest means of cholesterol, Triglyceride and HDL were detected in hypertensive IHD patients (264.3, 349.1, and 29.24 mg/dl respectively) as compared with non-hypertensive IHD patients group (217.5, 226.1 and 22.02 mg/dl), respectively. The study showed a significant negative correlation between VWF and LDL among IHD patients and showed a positive correlation of VWF with each of cholesterol, triglyceride, and HDL among IHD patients.In conclusion, the findings of the study suggest that patients with ischemic heart disease (IHD) have elevated levels of the von Willebrand factor. More research is needed to fully understand the relationship between VWF and cardiovascular disease and to determine the clinical utility of its measuring in the diagnosis and management of these conditions.

Abstract
BACKGROUND The coronavirus infectious disease 2019 (COVID-19) has been shown to be more lethal in the elderly (>65 years), especially those with co-morbidities. This study examined the impact of the pandemic lockdown period on trends in elderly medical admissions and deaths. METHODOLOGY This is a retrospective study of elderly medical admissions and deaths in the medical wards of a Nigerian hospital. Data for the months of March, April, May, June, and July of 2020 was compared to the same months before (2019) and after (2021). Analysis was done using STATA version 15.0. RESULTS During the study period, two hundred and seventy-six elderly patients were admitted, with a mean age (±SD) of 73.4 ± 7.4 years. The most common diagnoses at admission were chronic kidney disease (CKD) (26.85%, n=74) and hypertensive heart disease (HHD) (21.7%, n=60). The highest admission was in 2021, with a total of 99 (35.9%). Overall, 60 mortalities were recorded, with a proportional mortality rate of 21.7%, which was highest in 2020 (25.0%) and lowest in 2021 (17.1%). There was no difference between the mortality rates of 2019 versus 2020 (P=0.82) and 2020 versus 2021(P=0.18). Sepsis (35.0%) and CKD (25.0%) were the major contributors in 2019. CONCLUSION CKD and HHD were the most common diagnoses at admission, whereas sepsis, CKD, and CVD were the commonest causes of death. The Covid-19 pandemic did not significantly alter the elderly admission pattern in our setting.

Abstract
Abstract
Background/Introduction
Q-FFICIENCY evaluated 12-month (M) safety and efficacy of temperature-controlled paroxysmal atrial fibrillation ablation with a novel contact force-sensing, radiofrequency catheter with 3 microelectrodes and 6 thermocouples. Patients underwent pulmonary vein isolation with very high-power short-duration (vHPSD; 90 W/ up to 4 s) mode in combination with conventional-power temperature-controlled (CPTC; 25–50 W) mode.
Purpose
To assess procedural efficiency, safety, and 12M outcomes of participants ablated under near-zero fluoroscopy guidance compared to procedures performed with standard fluoroscopy.
Methods
In this US multi-centre (22 sites), non-randomised investigational study, patients underwent pulmonary vein isolation with vHPSD as primary ablation mode; CPTC was used for PV touch-up or non-PV ablation. Primary safety endpoint was incidence of primary adverse events ≤7 days post-procedure. Primary effectiveness was freedom from documented atrial tachyarrhythmia recurrence and additional pre-defined failure modes (acute failure, repeat ablation, new/higher dose anti-arrhythmic drug). Participants were followed-up through 12M post-ablation (3M blanking & 9M evaluation) to assess safety, effectiveness, and healthcare utilisation.
Results
Of 191 participants enrolled (63.5±10.7 years, CHA2DS2-VASc 2.4±1.5, 60.7% men), 166 were ablated with the investigational catheter, and 165 had fluoroscopy data available for inclusion in this analysis. Forty-four participants received ≤1 minute of fluoroscopy. Compared to the >1-minute of fluoroscopy cohort, the ≤1-minute group showed improved efficiencies in all procedural parameters (Table). Primary adverse event rates were similar among groups (≤1-minute, 4.5%; >1-minute, 3.3%). Kaplan-Meier estimated 12M clinical success rates (i.e., freedom from documented symptomatic recurrence) were similar regardless of fluoroscopy exposure (≤1-minute, 85.4%; >1-minute, 86.0%). Freedom from cardiovascular hospitalisation 12M post-ablation was comparable among groups (90.8% vs 88.0%).
Conclusion
Near-zero fluoroscopy paroxysmal atrial fibrillation ablation with the novel temperature-controlled catheter in vHPSD mode, alone or combined with CPTC, led to enhanced procedural efficiencies with good effectiveness and clinical success without comprising safety.

Abstract
Triple-negative breast cancer (TNBC) is associated with inferior outcomes. The use of adjuvant chemotherapy is the mainstay of treatment, and its efficacy was demonstrated to be correlated with tumor size. Different guidelines exist regarding chemotherapy in early-stage TNBC. This study uses ICES database to examine the outcomes of the use of adjuvant chemotherapy in stage I TNBC in Ontario stratified by tumor size. Records of TNBC patients diagnosed in 2012 to 2014 were collected from ICES database. Stage I patients were analyzed by tumor size: T1a (≤ 0.5 cm), T1b (> 0.5 cm and ≤ 1.0 cm), and T1c (> 1.0 cm and ≤ 2.0 cm). Kaplan-Meier curves, log-rank test statistic, and Cox's proportional hazard regression were used to compare differences in overall survival (OS) between chemotherapy and no-chemotherapy groups. Of 610 patients, 183 had tumor sizes ≤ 1 cm, representing stages T1aN0M0 and T1bN0M0, and 427 had tumors > 1 cm to 2 cm, representing stage T1cN0M0. Patients with tumors ≤ 1 cm who received chemotherapy did not have a significant difference in OS compared to the no-chemotherapy group (p = 0.41, hazard ratio (HR) 0.40, 95% confidence interval (CI) 0.021-2.5). However, patients with tumor sizes > 1 cm to 2 cm who received chemotherapy demonstrated significantly better OS compared to those without (p = 0.023, HR = 0.40, 95% CI 0.16-0.86). Patients with TNBC stage T1cN0M0 should receive adjuvant chemotherapy. For TNBC tumors ≤ 1 cm, avoidance of chemotherapy can be considered. Prospective research should further investigate the efficacy of chemotherapy in TNBC stages T1a-bN0M0.Trial Registration University of Windsor REB#16-119.

Abstract
OBJECTIVE Insufficient water intake has been a global health concern as it is linked to numerous adverse health consequences. Risk factors for dehydration include low fluid intake, sun and heat exposure which is a key element especially in the Gulf region. The aim of this study was to identify the prevalence and the impinging factors of hypohydration among college students in UAE. SUBJECTS AND METHODS Bioelectrical Analysis Impedance (BIA), attained using BodyStat 1,500 MDD, was used to assess participants' body water levels. Adequate hydration level was defined as body water level of 50-60% for females and 55-65% for males. Alongside this, a scale and a stadiometer were used to measure the participants' weight and height in order to calculate their BMI. A self-administered questionnaire was also used to assess and correlate the test findings with the risk factors, signs and symptoms, and the level of knowledge awareness of the participants. RESULTS Of the 201 university students that participated in the study, 41.3% were hypohydrated, 55.7% were well hydrated and 3% were hyper-hydrated. Among hypohydrated participants, 56.6% were females and 43.4% were males, highlighting that females were at higher risk of becoming dehydrated than males. A major factor that negatively affected hydration status was BMI; as BMI increased, water percentage and therefore hydration status decreased. We checked for numerous signs and symptoms that could indicate hypohydration levels, and the following were the top five most prevalent among our participants: dry lips (51.90%), thirst (46.90%), tiredness (46.80%), dry skin (39.70%) and headache (36.90%). According to The Urine Color Chart (Human Kinetics, Champaign, IL, USA), 3.5% were classified as dehydrated, 46% were in danger of getting hypohydration levels while 19.5% were classified as having good hydration levels. There was no significant correlation between water intake and urine colour chart (p = 0.334). Among the study participants, 64.2% acquired their knowledge from internet, 30.80% from TV and radio and 26.90% from books and courses. The behavior aspect of the participants when feeling thirsty, was that 79% of them would resort to water, while 11% resorted to soft drinks and 10% to juices. CONCLUSIONS The prevalence of hypohydration levels was 41.3% among the study participants of young university students. The main risk factors affecting hydration levels were BMI and gender. This signifies the importance of good hydration habits which were not commonly practiced among students even though they had adequate knowledge regarding the topic. Regular check-ups held intermittently can aid in recognizing those at risk of dehydration and help in educating about the importance of such topic especially regionally.

Abstract
Abstract
Study question
Is follicular phase or luteal phase stimulation more effective in progestin primed double stimulation protocol in poor responders?
Summary answer
The luteal phase stimulation was more effective than follicular phase stimulation in the progestin primed dual stimulation protocol in poor responders.
What is known already
Poor ovarian responders involve 9–24% of patients undergoing in vitro fertilization (IVF), with the management of these patients posing an everyday practical challenge.
Owing to the follicular waves theory, two or three waves of folliculogenesis were detected during the interovulatory interval, two consecutive ovarian stimulation protocols could be initiated in the follicular phase and the subsequent luteal phase. This is an effective way to increase the number of oocytes and embryos obtained over a relative short period of time. Furthermore, there is increasing evidence that progestins can be a reliable method of preventing premature LH surge during ovarian stimulation.
Study design, size, duration
This was a randomized controlled study performed at the Infertility and Assisted Reproduction Unit of ElShatby Maternity Hospital, Alexandria University and Madinah Fertility Centre. The study was conducted on 90 infertile women with poor ovarian response as defined by the Bologna criteria. 7 patients were excluded due to protocol violation, loss to follow-up and patient withdrawal. The study commenced in September 2020 and was finalized in September 2021.
Participants/materials, setting, methods
Group 1
45 patients were given the progestin primed double stimulation protocol. Dydrogesterone was started from the first day of the ovulation induction till the end of luteal phase stimulation. Embryo transfer was scheduled in a subsequent cycle.
Group 2
45 patients were given the flexible GnRh antagonist protocol in 2 cycles. The best blastocyst from either cycle was transferred in the second cycle.
Main results and the role of chance
When comparing the follicular and luteal phases, the M2 oocytes number retrieved in the luteal phase was statistically significantly higher than the follicular phase, with the median number of 4 oocytes against a median number of 2 oocytes (P value 0.001). The fertilization rate was significantly higher in the M2 oocytes of the luteal phase stimulation (P value 0.04). The resultant embryos from the luteal stimulation phase were statistically significantly higher than the follicular phase, with the median number of 3 embryos against a median number of 1 embryo (P value <0.001). However, we found that the days of controlled ovarian hyperstimulation were statistically significant higher in stimulation of the luteal phase with the median of 12 days against the 10 days seen in follicular phase stimulation (P value 0.002). Consequently, the total dosage of gonadotropins was statistically significant higher in the luteal phase with a P value of 0.007.
After Subgroup analysis, Poseidon Group 4 patients demonstrated that a significantly higher number of oocytes were retrieved after the progestin primed double stimulation than after two waves of flexible GnRh antagonist stimulation (median of 12 oocytes against a median of 10 oocytes with P value 0.01).
Limitations, reasons for caution
Firstly, preimplantation genetic testing was not performed to detect euploid embryos which could be vital when comparing both the phases and the protocols. Secondly, despite the importance of the live birth rate as an outcome measure, we did not enroll this measure.
Wider implications of the findings
In the light of our findings, we recommend the usage of progestin primed dual stimulation protocol in poor responder patients. Additionally, we call for multicentric randomized controlled research to verify this protocol as a first-line treatment protocol in poor responder patients.

Abstract
e12511 Background: Triple-negative breast cancer (TNBC) has been associated with poorer long-term outcomes compared to other breast cancer subtypes. Due to the lack of targeted therapies, the use of adjuvant chemotherapy is the mainstay of treatment, and its efficacy has demonstrated to be correlated with tumor size. Currently, different national guidelines exist regarding chemotherapy in early stage I TNBC. This study aims to examine the outcomes of the use of adjuvant chemotherapy in stage I TNBC stratified by tumor size and treated in Ontario, using the ICES database. Methods: Records of stage I TNBC patients diagnosed in 2012 to 2014 were collected from the ICES database and analysed. Kaplan-Meier curves and log-rank tests were used to compared differences in overall survival (OS) between groups. Stage I TNBC cancer patients were analyzed by tumor size: T1a (< 0.5 cm), T1b (> 0.5 cm and < 1.0 cm) and T1c (>1.0 cm and < 2.0 cm). A Cox proportional hazard model was used to determine significance of variables. Results: Of the 610 stage I TNBC patients, 183 had tumor sizes ≤ 1cm, representing stages T1aN0M0 and T1bN0M0, and 427 had tumor sizes > 1cm to 2cm, representing stage T1cN0M0. Patients with tumor sizes ≤ 1cm who received adjuvant chemotherapy did not have a significant difference in OS compared to those who did not receive adjuvant chemotherapy (p = 0.41, hazard ratio (HR) = 0.40, 95% confidence interval (CI) 0.021-2.5). However, patients with tumor sizes > 1cm to 2cm who received adjuvant chemotherapy demonstrated a significantly better OS compared to those without (p = 0.023, HR = 0.40, 95% CI 0.16-0.86). Conclusions: Patients with TNBC stage T1cN0M0 should receive adjuvant chemotherapy for better OS. For stages T1aN0M0 and T1bN0M0, patients may be overtreated and avoidance of adjuvant chemotherapy can be considered at this time. Prospective studies should investigate the efficacy of adjuvant chemotherapy in TNBC patients with stage T1aN0M0 and T1bN0M0.

Abstract
This research outlines a digital imaging method under development to systemize a rapid in-field corrosion evaluation measure, to evaluate and monitor the degree of corrosion on target corrosion-prone parts on light-duty vehicles. This procedure uses digital imaging to study and compare corrosion levels of 228 vehicles that were treated with aftermarket applications of corrosion prevention products versus 141 vehicles that were untreated. It introduces a Corrosion Index (CI) as a common measure. Single-factor and two-factor analysis of variance (ANOVA) of the digitally-based corrosion measurements show statistically significant correlations between CI and treatment (treated versus untreated), as well as CI, vehicle age, and treatment. The ANOVA results show that the aftermarket-treated vehicles have statistically significantly less corrosion than the untreated vehicles, demonstrating that digital image analysis is a viable method of measuring corrosion on corrosion-prone vehicle parts, offering the potential to monitor and track the performance/efficacy of aftermarket corrosion treatment in real-time.

Abstract
The exact incidence of neurological complications from coronavirus disease 2019 (COVID-19) infection remains unknown. Neurological symptoms are more common with severe form of the disease. Through neuro-invasion, the virus can affect both neurons and glial cells and induce wide range of neurological pathologies. CNS symptoms is commoner representing 91% of all neurological patients with 9% only with PNS. PNS manifestations showed variable results where visual impairment and nerve pains were more frequent in the severe COVID-19 category of patients. This is a 2 case report study of post covid optic neuritis , both after severe covid infection and hospitalization ,they developed acute onset visual affection mostly1.5 month in the first case and 2 month in the second one after almost complete cure. The first case had monocular delayed perception of vision , the second one had complete visual loss of one eye of unexplained causes. All neurological and ophthalmological investigations were normal apart from visual evoked potentials that showed small amplitude p100 response in the first case and absent response in the last one. This supports a study Based on murine models of other CoVs, stated that viral-induced optic neuritis secondary to autoantibody production against neuroretina should also be included in the differential diagnosis and infected patients should be monitored for signs of neuroretinal degeneration in the long term.

Abstract
Addition of platinums to combination chemotherapy for triple negative breast cancer (TNBC) has shown efficacy and is increasingly accepted in the clinic, yet optimal delivery is unknown. A prospective clinical trial with TNBC patients was conducted to determine the optimal chemotherapy regimen to deliver carboplatin with standard dose dense ACT. Tissue microarray was conducted to isolate markers indicative of response to treatment. 90 TNBC patients were enrolled onto our trial. The most successful version placed the carboplatin on the second and final paclitaxel treatment with liberal hematological parameters. Our final regimen had the lowest grade 3 or 4 toxicities, no delays, no dose reductions of carboplatin, and 32% reduction in paclitaxel doses. Stage I (AJCC7) patients did well with carboplatin-based chemotherapy with zero relapse rate. Reduction in protein levels of androgen receptor and PD-L1 were found to be potential indicators of patient relapse. We have optimized a protocol for the addition of carboplatin to standard of care chemotherapy in TNBC patients. Early data indicates reduced protein levels of androgen receptor and PD-L1 as indicators of response to treatment.Trial registration This trial was registered at Canadian Cancer Trials. http://www.canadiancancertrials.ca/.

Abstract
OBJECTIVES The objective of the current study was to investigate the relationship between changes in vital signs and intensive care unit (ICU) admission. Windsor Regional Hospital treats 15-20 new patients a year with acute leukemia. These patients are at increased risk of neutropenic fevers and admission to the ICU following induction chemotherapy. METHODS Retrospective review examined the correlation between acute leukemia patient vitals and ICU admission. The analysis included 37 patients: 7 ICU versus 30 controls. Changes were compared to baseline over 24 hours prior to ICU admission or 5 days after the initiation of induction chemotherapy in the following vital signs: heart rate (HR), mean arterial pressure (MAP), temperature (T), respiratory rate (RR), and fraction of inspired oxygen (FiO2) required to maintain a stable oxygen saturation. RESULTS RR and FiO2 demonstrated significant change over baseline leading up to ICU admission within the ICU group. T, HR and MAP did not demonstrate significant changes over time in either group. RR, FiO2 and HR were significantly higher in the ICU group at time zero compared with the control group. RR was recorded least frequently in the 24 hours leading up to ICU admission. DISCUSSION Changes in RR and FiO2 predicted clinical deterioration requiring ICU admission in acute leukemia patients. This is consistent with the predominant reason for ICU admission which was respiratory failure. CONCLUSION We present preliminary evidence to support enhanced monitoring of RR and FiO2 in acute leukemia patients following induction chemotherapy with early intervention if identified.
