Syringing has limited reliability in differentiating nasolacrimal duct stenosis from functional delay

PURPOSE

To elucidate the role of syringing in assessing nasolacrimal duct (NLD) stenosis and non-anatomical functional NLD delay.

METHODS

Consecutive adult patients with epiphora attending a tertiary lacrimal clinic from June 2011 to March 2021 were reviewed. Cases with evidence of canalicular stenosis or other identifiable causes of epiphora were excluded. Following syringing, patients were investigated with dacryocystography (DCG) and dacryoscintigraphy (DSG). The sensitivity and specificity of syringing were evaluated using the combined findings on DCG and DSG.

RESULTS

A total of 289 symptomatic lacrimal systems (197 patients; mean age 65.5 ± 14.9 years, 66% females) were included. More than one-third of cases with both normal DCG and DSG were noted to have some degree of reflux on syringing (specificity = 65.1%, 95% CI 50.2-77.6%). The sensitivities were considerably low for NLD stenosis (i.e., stenosis on DCG and delay on DSG) and for functional NLD delay (i.e., normal DCG and delay on DSG), of which 43.7% (95% CI 32.2-55.9%) and 54.3% (95% CI 45.7-62.7%) had full patency on syringing, respectively (p = 0.17).

CONCLUSIONS

Full patency on syringing was unreliable for ruling out NLD stenosis and functional delay. Furthermore, a positive syringing may be associated with functional NLD delay and cannot reliably differentiate it from stenosis.

A bidirectional Hopf bifurcation analysis of Parkinson's oscillation in a simplified basal ganglia model

In this paper, we study the parkinson oscillation mechanism in a computational model by bifurcation analysis and numerical simulation. Oscillatory activities can be induced by abnormal coupling weights and delays. The bidirectional Hopf bifurcation phenomena are found in simulations, which can uniformly explain the oscillation mechanism in this model. The Hopf1 represents the transition between the low firing rate stable state (SS) and oscillation state (OS), the Hopf2 represents the transition between the high firing rate stable state (HSS) and the OS, the mechanisms of them are different. The Hopf1 and Hopf2 bifurcations both show that when the state transfers from the stable region to the oscillation region, oscillatory activities always originate from the beta frequency band, and then gradually evolve into the alpha frequency band, the theta frequency band and delta frequency band in this model. We find that the changing trends of the DF and oscillation amplitude (OSAM) are contrary, oscillation activities in lower frequency band are more stable than that in higher frequency band. The effect of the delay in inhibitory pathways is greater than that of in excitatory pathways, and appropriate delays improve the discharge activation level (DAL) of the system. In all, we infer that oscillations can be induced by the follow factors: 1. Improvement of the DAL of the globus pallidus externa (GPe); 2. Reduce the DAL of the GPe from the HSS or the discharge saturation state; 3. The GPe can also resonate with the subthalamic nucleus (STN).

Fewer head and neck cancer diagnoses and faster treatment initiation during COVID-19 in 2020: A nationwide population-based analysis

Background

Inevitably, the emergence of COVID-19 has impacted non-COVID care. Because timely diagnosis and treatment are essential, especially for patients with head and neck cancer (HNC) with fast-growing tumours in a functionally and aesthetically important area, we wished to quantify the impact of the COVID-19 pandemic on HNC care in the Netherlands.

Material and Methods

This population-based study covered all, in total 8468, newly diagnosed primary HNC cases in the Netherlands in 2018, 2019 and 2020. We compared incidence, patient and tumour characteristics, primary treatment characteristics, and time-to-treatment in the first COVID-19 year 2020 with corresponding periods in 2018 and 2019 (i.e. pre-COVID).

Results

The incidence of HNC was nearly 25% less during the first wave (n = 433) than in 2019 (n = 595) and 2018 (n = 598). In April and May 2020, the incidence of oral cavity and laryngeal carcinomas was significantly lower than in pre-COVID years. There were no shifts in tumour stage or alterations in initial treatment modalities.

Regardless of the first treatment modality and specific period, the median number of days between first visit to a HNC centre and start of treatment was significantly shorter during the COVID-19 year (26–28 days) than pre-COVID (31–32 days, p < 0.001).

Conclusion

The incidence of HNC during the Netherlands’ first COVID-19 wave was significantly lower than expected. The expected increase in incidence during the remainder of 2020 was not observed. Despite the overloaded healthcare system, the standard treatment for HNC patients could be delivered within a shorter time interval.

Extinction and stationary distribution of a stochastic COVID-19 epidemic model with time-delay

We reformulate a stochastic epidemic model consisting of four human classes. We show that there exists a unique positive solution to the proposed model. The stochastic basic reproduction number R0s is established. A stationary distribution (SD) under several conditions is obtained by incorporating stochastic Lyapunov function. The extinction for the proposed disease model is obtained by using the local martingale theorem. The first order stochastic Runge-Kutta method is taken into account to depict the numerical simulations.

Time from first seen in specialist care to surgery does not influence survival outcome in patients with upfront resected pancreatic adenocarcinoma

BACKGROUND

This study evaluated the impact of time to surgery (TTS) on overall survival (OS), disease free survival (DFS) and postoperative complication rate in patients with upfront resected pancreatic adenocarcinoma (PA).

METHODS

We retrospectively included patients who underwent upfront surgery for PA between January 1, 2004 and December 31, 2014 from four French centers. TTS was defined as the number of days between the date of the first consultation in specialist care and the date of surgery. DFS for a 14-day TTS was the primary endpoint. We also analyzed survival depending on different delay cut-offs (7, 14, 28, 60 and 75 days).

RESULTS

A total of 168 patients were included. 59 patients (35%) underwent an upfront surgery within 14 days. Patients in the higher delay group (> 14 days) had significantly more vein resections and endoscopic biliary drainage. Adjusted OS (p = 0.44), DFS (p = 0.99), fistulas (p = 0.41), hemorrhage (p = 0.59) and severe post-operative complications (p = 0.82) were not different according to TTS (> 14 days). Other delay cut-offs had no impact on OS or DFS.

DISCUSSION

TTS seems to have no impact on OS, DFS and 90-day postoperative morbidity.

A prospective study of neurodevelopmental trends between 3 and 24 months in normocephalic infants with prenatal Zika virus exposure: Evidence of emerging communication delays in the NATZIG cohort

Developmental trends between 3 and 24 months were assessed in 194 normocephalic infants with prenatal Zika virus exposure. Bayley Scales of Infant and Toddler Development Screening Test-3rd Edition cognitive scores remained in the typical range. Communication skills developed at a slower rate suggesting that neurodevelopmental delays may emerge at older ages.

Factors Associated With Inpatient Endoscopy Delay and its Impact on Hospital Length-of-Stay and 30-Day Readmission

BACKGROUNDS AND AIMS

Inpatient endoscopy delay (IED) negatively impacts the delivery of high-quality care. We aimed to identify factors associated with IED and evaluate its effect on hospital length-of-stay (LOS) and readmission.

METHODS

This was a retrospective analysis of all inpatient endoscopies performed between November 2017 and November 2019 at a tertiary care center. IED was defined as the number of days elapsed between anticipated versus actual procedure day. Data were extracted from the endoscopy documentation software and via electronic chart review. Multivariate logistic regressions were modeled to determine variables associated with IED and hospital readmission.

RESULTS

A total of 4239 inpatients (mean age, 58.3 years; 50.3% women) underwent endoscopic procedures during the study period of which 819 patients (19.3%) experienced a delay. IED resulted in a median prolonged LOS of 2 days (interquartile range, 1-2 days). Patients with IED were less likely to have an etiology identified on endoscopy (odds ratio [OR], 0.73; 95% confidence interval [CI], 0.63-0.86; P < .001). The 2 most common causes for delays were poor bowel preparation (n = 218; 27%) and lack of endoscopy personnel/unit availability (n = 197; 24.4%). Independent predictors of IED included: older age (OR, 1.1; 95% CI, 1.01-1.03; P = .03), female sex (OR, 1.20; 95% CI, 1.03-1.40; P = .02), use of antithrombotics (OR, 1.30; 95% CI, 1.08-1.57; P = .006), opioids (OR, 1.23; 95% CI, 1.04-1.44; P = .012), being on contact isolation (OR, 1.38; 95% CI, 1.09-1.75; P = .008), and colonoscopy (OR, 1.50; 95% CI, 1.27-1.77; P < .001). Conversely, inpatients admitted to a dedicated GI medicine service were less likely to have IED (OR, 0.79; 95% CI, 0.65-0.96; P = .02). IED was the only independent predictor of 30-day readmission (OR, 1.22; 95% CI, 1.02-1.47; P = .03).

CONCLUSIONS

IED occurred frequently, unfavorably prolonged LOS, and was an independent risk factor for 30-day readmission. We provide a comprehensive analysis of actionable variables associated with IED that can be targeted to improve inpatient endoscopy delivery.

Predicting disclosure latency in substantiated cases of child sexual abuse

OBJECTIVE

Children who experience sexual abuse (CSA) often delay disclosure, thus impeding early interventions. This study explores predictors of disclosure latency in a sample of forensically substantiated cases.

METHODS

Court files were analyzed for a total of 124 cases of CSA. The ground truth of the alleged victims' statements had been substantiated by at least one inclusion criterion-an evaluation of the alleged victims' statement as credible by psychological experts applying Statement Validity Assessment (SVA), or the conviction of the suspected offender by the court. Six possible predictors of disclosure latency were tested individually and in a joint negative binomial regression model.

RESULTS

Younger age of the child at abuse onset and intrafamilial (vs. extrafamilial) child-perpetrator relationships (including stepparents) were associated with prolonged disclosure latency. No predictive evidence was found for the child's gender, severity of abuse, or offender's usage of violent or nonphysical strategies to prevent disclosure.

CONCLUSION

This study contributes to understanding the processes of disclosure by reassessing formerly identified predictors of disclosure latency in a sample of forensically substantiated cases. Results are in line with suggestions to further develop effective prevention programs for younger children (e.g., for elementary school) and to explicitly discuss the issue of intrafamilial abuse.

The effect of COVID-19: Adopted changes and their impact on management of musculoskeletal oncology care at a tertiary referral centre

BACKGROUND

COVID-19 pandemic has disrupted access to healthcare. Delay in diagnosis and onset of care increases cancer related mortality. We aim to analyse its impact on patient profile, hospital visits, morbidity in surgically treated patients and process outcomes.

METHODS

We analysed an ambi-directional cohort from 16th March to June 30, 2020 (Pandemic cohort, PC) as compared to 2019 (Pre-pandemic cohort, PPC). We measured, new patient registrations, proportion of 'within state' patients vs 'rest of India', median time to treatment decision, proportion of patients seeking 'second opinions', modality of initial treatment (surgery/radiotherapy/chemotherapy), 30-day post-operative morbidity/mortality and conversion of inpatient-to 'teleconsult' in the PC.

RESULTS

Between the 2 cohorts, new registrations declined from 235 to 69 (70% reduction). The percentage of 'within state' patients increased from 41.7% to 53.6% (11.9% increase). There was a decline in second opinion consults from 25% to 16%. The median time to decision-making decreased to 16 days in PC vs 20 days in PPC (20% reduction). Surgery was the first line of treatment in 40% as compared to 34% in the PPC with a mean time to surgery of 24 days in PC compared to 36 days in PPC (33% reduction). 66 surgeries were performed in the PC compared to 132 in the PPC. Thirty day post operative morbidity needing readmission remained similar (18% PC, vs 17% PPC). Perioperative intensive care remained similar in both cohorts. Teleconsultation was deemed medically safe in 92.8% (439/473 patients).

CONCLUSIONS

The COVID 19 pandemic has substantially reduced access and onset to cancer care. Post operative morbidity and mortality did not seem to worsen with triage. Teleconsultation is an effective tool in optimizing follow up strategy.

Effect of pre-hospital notification on delays and neurological outcomes in acute ischemic stroke

BACKGROUND

Since timely thrombolytic therapy is a crucial variable in acute ischemic stroke recovery, health care systems are trying to find new interventions to reduce treatment delay in order to improve neurological function. In Iran, SAMA code as a pre-hospital notification plan has been developed to help emergent stroke treatment. This study aimed to compare delay to thrombolysis therapy and neurological outcomes between SAMA-transported and self-transported patients in ischemic stroke.

METHODS

In this retrospective cohort study, the data of 185 stroke patients treated with intravenous thrombolysis from Mar 2016 to May 2020 were collected. P-value < 0.05 was considered as significant.

RESULTS

The results showed that delays reduced in SAMA-transported patient compared to that in self-transported patients. There was a significant difference in Onset to Needle time, Door to Needle Time, and Door to CT Time but not Onset to Door time between SAMA-transported and self-transported patients (P values: 0.001, 0.000, 0.001, and 0.22 respectively). However, there was no significant difference between two groups in terms of neurologic deficit severity.

CONCLUSIONS

Although pre-hospital notification could partially reduce treatment delays in stroke, that reduction was not enough to impact on neurologic deficit recovery. It seems more reduction in delay is needed to significantly improve neurological dysfunctions.

Delayed Onset Acute Subdural Hematoma after Burr Hole Drainage in a Patient with Chronic Subdural Hematoma and Liver Cirrhosis

Although acute intracranial bleeding after burr hole drainage for chronic subdural hematoma (SDH) is rare, it could still occur and is associated with a poor clinical outcome. Although rare, most of them occur immediately or within a few days after drainage, especially in patients who are on antiplatelet drugs or anticoagulants. We report an unusual case of delayed-onset acute SDH that developed 14 days after burr hole drainage of chronic SDH in a 54-year-old man with liver cirrhosis and thrombocytopenia. The possible pathophysiological mechanisms of this rare entity are discussed, and the relevant literature is reviewed.

[D-CBP study: Evaluation of lung cancer management times]

INTRODUCTION

Lung cancer is the leading cause of cancer-related death. Delays may have an impact on patient survival. The objective of this study was to evaluate the diagnostic and therapeutic management times for patients admitted for lung cancer treatment in the Respiratory Department of CHU de Caen Normandie.

MATERIALS AND METHODS

This is a retrospective, single-center and observational study, conducted on all patients treated for lung cancer from June 2017 to January 2018 in our department of pneumology in the Caen Normandie CHU. The main median times were investigated were: Global Time (abnormal imaging-treatment), Diagnosis time (abnormal imaging-diagnosis) and Treatment Time (diagnosis-treatment).

RESULTS

One hundred and twenty-seven (127) patients were included. Median global time was 55.5 days [31,25; 393], median diagnosis time was 22 days [13; 49], and median treatment time was 24.5 days [12,25; 45].

DISCUSSION

Our treatment times are consistent with those previously published. Areas for improvement are being developed in accordance with the 2014-2019 cancer plan, in particularly the creation in our institution of a specific care pathway for patients with lung cancer.

Age-appropriate vaccination coverage and its determinants in children aged 12-36 months in Nepal: a national and subnational assessment

Background

Vaccination is one of the effective ways to develop immunity against potential life-threatening diseases in children in early age. This study is focused on analysing the age-appropriate vaccination coverage at national and subnational levels and identify the factors associated with age-appropriate coverage in Nepal.

Methods

460 children aged 12–36 months were included in the study. The data was obtained from Nepal Demographic and Health Survey (NDHS) 2016–17. Age-appropriate coverage of Bacillus Calmette-Guerin vaccine (BCG), oral polio vaccine (OPV) doses 1–3, pentavalent vaccine (PE) doses 1–3, and first dose of measles, mumps, and rubella vaccine (MMR) were estimated using Kaplan Meier method. Multilevel logistic regression with random intercept was used to identify the factors associated with age-appropriate vaccination.

Results

The crude coverage of the vaccines included in the study ranged from 91.5% (95% CI, 88.5–93.7) for PE3 to 97.8% (95.8–98.7) for BCG. Although the crude coverage of all the vaccines was above 90%, the age-appropriate coverage was significantly low, ranging from 41.5% (36.5–46.6) for PE3 to 73.9% (69.2–78.1) for PE1. Furthermore, high disparity in timely vaccination coverage was observed at regional level. Compared to the age-appropriate vaccination coverage in other provinces, Province 2 had the lowest coverage of all, followed by that in Province 6. The timeliness of vaccination was significantly associated with subnational regions i.e., provinces and the season of childbirth.

Conclusion

Although the immunization program in Nepal has achieved the target of 90% crude coverage of all the childhood vaccines, the age-appropriate coverage is significantly low which undermines the effectiveness of the vaccines administered. Thus, along with crude coverage, timeliness of the vaccines administered should be taken into consideration and thoroughly monitored at national and subnational levels. Provincial government should formulate tailored strategies to ensure the timely administration of the childhood vaccines.

A class of delay SIQR-V models considering quarantine and vaccination: Validation based on the COVID-19 perspective

To contain the novel SARS-CoV-2 (COVID-19) spreading worldwide, governments generally adopt two measures: quarantining the infected people and vaccinating the susceptible people. To investigate the disease latency's influence on the transmission characteristics of the system, we establish a new SIQR-V (susceptible-infective-quarantined-recovered-vaccinated) dynamic model that focus on the effectiveness of quarantine and vaccination measures in the scale-free network. We use theoretical analysis and numerical simulation to explore the evolution trend of different nodes and factors influencing the system stability. The study shows that both the complexity of the network and latency delay can affect the evolution trend of the infected nodes in the system. Still, only latency delay can destroy the stability of the system. In addition, through the parameter sensitivity analysis of the basic reproduction number, we find that the effect of the vaccination parameter α on the basic reproduction number R 0 is more significant than that of transmission rate β and quarantine parameter σ . It shows that vaccination is one of the most effective public policies to prevent infectious diseases' spread. Finally, we calculate the basic reproduction numbers that are greater than one for Germany and Pakistan under COVID-19 and validate the model's effectiveness based on the disease data of COVID-19 in Germany. The results show that the changing trend of the infected population in Germany based on the SIQR-V model is roughly the same as that reflected by the actual epidemic data in Germany. Therefore, providing suggestions and guidance for treating infectious diseases based on this model can effectively reduce the harm caused by the outbreak of contagious diseases.

Technical note: On the actuator rate limit effect in reaction curves

While actuator rate limit is common and counted in practical engineering, it has not drawn enough attention in control synthesis especially system identification. In this note, it aims to construct a new identification framework for first-order plus time-delay (FOPTD) systems affected by actuator rate limit. It is found that the rate limit can lead to an illusory delay in system reaction curves. Furthermore, necessary quantitative analyses are given to validate that excessively estimated or illusory delay significantly influences estimation accuracy of other parameters and subsequently degrades control performance. Two illustrative examples and experimental results are provided to demonstrate the adverse effect of actuator rate limit on system identification and the effectiveness of the proposed model structure on control performance.

Cancer management during the COVID-19 pandemic: Choosing between the devil and the deep blue sea

COVID-19 was declared a "Public Health Emergency of International Concern" in March 2020. Since then, drastic measures were implemented to reduce the virus spread. These measures prevented cancer patients from receiving prompt medical care. A delay in testing and treating cancer patients is thought to protect them from serious COVID-19 complications but exposes them at the same time to the risk of disease progression and cancer related mortality. Healthcare providers are therefore facing the dilemma of choosing between two unpleasant scenarios. To shed light upon the matter, we present in this review article, based on an extensive search of the literature, an overview of the delay in the management of cancer patients, possible contributors to this delay and its benefits and risks on cancer patients' health.

Mathematical analysis of a cancer model with time-delay in tumor-immune interaction and stimulation processes

In this study, we discuss a cancer model considering discrete time-delay in tumor-immune interaction and stimulation processes. This study aims to analyze and observe the dynamics of the model along with variation of vital parameters and the delay effect on anti-tumor immune responses. We obtain sufficient conditions for the existence of equilibrium points and their stability. Existence of Hopf bifurcation at co-axial equilibrium is investigated. The stability of bifurcating periodic solutions is discussed, and the time length for which the solutions preserve the stability is estimated. Furthermore, we have derived the conditions for the direction of bifurcating periodic solutions. Theoretically, it was observed that the system undergoes different states if we vary the system's parameters. Some numerical simulations are presented to verify the obtained mathematical results.

Factors contributing to delay intensive care unit admission of critically ill patients from the adult emergency Department in Tikur Anbessa Specialized Hospital

BACKGROUND

The transfer time for critically ill patients from the emergency department (ED) to the Intensive care unit (ICU) must be minimal; however, some factors prolong the transfer time, which may delay intensive care treatment and adversely affect the patient's outcome.

PURPOSE

To identify factors affecting intensive care unit admission of critically ill patients from the emergency department.

PATIENTS AND METHODS

A cross-sectional study design was conducted from January 13 to April 12, 2020, at the emergency department of Tikur Anbesa Specialized Hospital. All critically ill patients who need intensive care unit admission during the study period were included in the study. A pretested structured questionnaire was adapted from similar studies. The data were collected by chart review and observation. Then checked data were entered into Epi-data version 4.1 and cleaned data was exported to SPSS Version 25 for analysis. Descriptive statistics, bivariate and multivariate logistic regression were used to analyze the data.

RESULT

From the total of 102 critically ill patients who need ICU admission 84.3% of them had prolonged lengths of ED stay. The median length of ED stay was 13.5 h with an IQR of 7-25.5 h. The most common reasons for delayed ICU admission were shortage of ICU beds 56 (65.1%) and delays in radiological examination results 13(15.1%). On multivariate logistic regression p < 0.05 male gender (AOR = 0.175, 95% CI: (0.044, 0.693)) and shortage of ICU bed (AOR = 0.022, 95% CI: (0.002, 0.201)) were found to have a significant association with delayed intensive care unit admission.

CONCLUSION

there was a delay in ICU admission of critically ill patients from the ED. Shortage of ICU bed and delay in radiological investigation results were the reasons for the prolonged ED stay.

COVID-19-related rotator cuff repair delay

Background

Although nonoperative treatment is effective for degenerative rotator cuff tears (RCTs), it remains unclear whether the delay created by a trial of nonoperative treatment negatively influences the outcome of a subsequent surgical repair. In March 2020, the COVID-19 pandemic resulted in an involuntary delay in the surgical treatment of rotator cuff disease, creating a natural experiment. The purpose of this study was to evaluate the outcomes and healing of patients who underwent delayed surgical treatment of chronic degenerative RCTs as compared with the nondelayed surgical treatment of RCTs.

Methods

This was a prospective study of two groups: patients planned to undergo arthroscopic rotator cuff repair between March 16, 2020 and May 1, 2020-the end of the ban on elective surgery-and patients who underwent rotator cuff repair starting six weeks after the ban on elective surgery had been lifted. Preoperatively and at six months postoperatively, we collected the Simple Shoulder Test, the American Shoulder and Elbow Surgeons (ASES) score, and the visual analog scale for pain. We also obtained magnetic resonance imaging (MRI) at six months postoperatively. A power analysis was conducted, and assuming a mean ± standard deviation ASES score of 93.1 ± 13.9 points and a minimum clinically important difference in the ASES score of 27.1 points, 7 patients per group (14 patients in total) would be necessary to have 90% chance of finding a difference.

Results

We included 15 patients within each group and obtained 100% follow-up at six months. In the delay group, the mean ± standard deviation delay was 63 ± 24 days. There were no significant preoperative differences between groups in demographics or tear characteristics. Intraoperatively, there were no differences between groups in repair characteristics. Using a repeated-measures analysis of variance, there were significant preoperative vs. postoperative differences in ASES scores (P < .001), visual analog scale scores (P < .001), and Simple Shoulder Test scores (P < .001), but no differences between groups (P = .910, .519, and 0.852, respectively). On MRI, within the delay group, 58% had healed, whereas within the control group, 85% had healed (P = .202).

Conclusion

COVID-19 caused a two-month delay in the operative treatment of RCTs. This delay did not significantly alter patient-reported outcomes. This delay resulted in a 27% difference in MRI healing rates, which was not statistically significant in this small study. Larger studies should be conducted as our results suggest that a delay in treatment may negatively impact healing rates.

Factors associated with delayed treatment initiation in an unselected cohort of patients with small-cell lung cancer

BACKGROUND

Small-cell lung cancer (SCLC) is an aggressive, rapidly progressive malignancy. Thus, expedient diagnosis and treatment initiation is important. This study identifies and quantifies factors associated with delayed diagnosis and treatment initiation in patients with SCLC and compares time to treatment in SCLC with a cohort of patients with non-small cell lung cancer (NSCLC).

MATERIALS AND METHODS

The study included all patients diagnosed with SCLC at a hospital in southern Norway in a ten-year period (2007-2016), and all NSCLC patients during the period 2013-2016. Total time to treatment (TTT), was defined as the number of days from date of referral due to suspicion of lung cancer to first day of treatment. Factors associated with prolonged TTT were estimated using multivariate median regression analysis.

RESULTS

The median TTT and interquartile range (IQR) for the 183 patients with SCLC was 16 (10-23) days. Factors associated with delayed TTT included outpatient versus inpatient evaluation (+8.4 days), number of diagnostic procedures (+4.3 days per procedure), stage I-III versus stage IV (+3.6 days) and age (+2.1 days per 10 years). In 2013-16, TTT in SCLC was 3.5 days shorter than in the period before and less than half that of NSCLC in the same period, 15 (9-22) versus 33 (22-50) days (p = 0.001).

CONCLUSION

Shorter TTT is seen in higher stage, while longer TTT is a result of increasing complexity of the diagnostic process and treatment decisions of patients with curative intent treatment. Knowledge on delaying factors can shorten TTT and improve clinical practice.

COVID-19 pandemic impact on uro-oncological disease outcomes at an Italian tertiary referral center

Purpose

To assess differences in referral and pathologic outcomes for uro-oncology cases prior to and during the COVID pandemic, comparing clinical and pathological data of cancer surgeries performed at an academic referral center between 2019 and 2020.

Methods

We collected data of 880 prostate biopsies, 393 robot-assisted radical prostatectomies (RARP) for prostate cancer (PCa), 767 trans-urethral resections of bladder tumor (TURB) and 134 radical cystectomies (RC) for bladder cancer (BCa), 29 radical nephro-ureterectomies (RNU) for upper tract urothelial carcinoma, 130 partial nephrectomies (PN) and 12 radical nephrectomies (RN) for renal cancer, and 41 orchifunicolectomies for testicular cancer. Data of patients treated in 2019 (before COVID-19 pandemic) were compared to patients treated in 2020 (during pandemic).

Results

No significant decline in uro-oncological surgical activity was seen between 2019 and 2020. No significant increase in time between diagnosis and surgery was observed for all considered cancers. No differences in terms of main pathologic features were observed in patients undergoing RARP, TURB, RNU, RN/PN, or orchifunicolectomy. A higher proportion of ISUP grade 3 and 4 PCa were diagnosed in 2020 at biopsy (p = 0.001), but this did not translate into worse pathological grade/stage at RARP. In 2020, more advanced disease features were seen after RC, including lymph node involvement (p = 0.01) and non-organ confined disease (p = 0.02).

Conclusion

Neither decline in uro-oncologic activity nor delay between diagnosis and treatment was observed at our institution during the first year of COVID-19 pandemic. No significant worsening of cancer disease features was found in 2020 except for muscle-invasive BCa.

Factors delaying chemotherapy in patients with breast cancer at a safety-net hospital

BACKGROUND

Despite advances in healthcare and improved chemotherapy, disparities in breast cancer outcomes continue to persist. Our aim was to evaluate socioeconomic factors that may impact timing of treatment for patients receiving chemotherapy in underserved communities.

METHODS

A review of patients with breast cancer who received neoadjuvant or adjuvant chemotherapy from 2015-2019 was conducted at a safety-net hospital. The primary outcomes were times from diagnosis to chemotherapy and surgery. Clinicodemographic factors including race, age, clinical stage, primary language, comorbidities, and median income by zip code were collected. Multivariable regression analysis was performed to evaluate for factors associated with the primary outcomes.

RESULTS

One hundred patients were identified. For the neoadjuvant group, median time from diagnosis to chemotherapy and surgery was 52 ± 34 days and 256 ± 59 days, respectively. For the adjuvant group, median time from diagnosis to surgery and chemotherapy was 24.5 ± 18 days and 94.5 ± 53 days, respectively. Non-English language and older age were associated with increased time to chemotherapy in the adjuvant group (p < 0.05). Language and age were not associated with increased time to surgery in both groups. Race, age, comorbidities, and income were not associated with delay in treatment in either groups.

CONCLUSIONS

Older age and non-English language were associated with prolonged time from surgery to adjuvant chemotherapy. Targeted interventions directed at patient education and decreasing language barriers especially post-operatively may decrease delays in treatment and subsequently reduce disparities seen in the breast cancer population.

Timing of pregnancy discovery among women seeking abortion. Contraception 2021;104:642-647. [PMID: 34363842 DOI: 10.1016/j.contraception.2021.07.110]

OBJECTIVE

Little is known about the incidence and causes of delay in recognition of pregnancy. Delay in pregnancy recognition is associated with later presentation for abortion and exacerbates the burdens in accessing care. Using Turnaway study data, this study assessed the prevalence of later pregnancy recognition among a sample of people who obtained or were denied a wanted abortion.

STUDY DESIGN

The Turnaway Study included telephone interviews of 956 women who sought an abortion in the first trimester or just over or under the gestational limit of one of 30 abortion facilities across the United States and in-depth interviews with 31 who completed 5 years of surveys. We describe women's experiences discovering pregnancy and conducted multivariate analyses assessing factors associated with later pregnancy discovery (after 13 weeks since last menstrual period [LMP]).

RESULTS

Most women seeking second trimester abortions recognized their pregnancy more than 8 weeks after their LMP; more than 1 in 5 recognized pregnancy after 20 weeks. In interviews, women explained that recognition was delayed because of a lack of pregnancy symptoms or concurrence of other conditions with symptoms similar to pregnancy. According to multivariate analyses, women who had never given birth (adjusted odds ratio [aOR] = 1.71; 95% confidence interval [CI]: 1.24, 2.35) and those who used hormonal contraceptives in the month of conception (aOR = 1.83; 95% CI: 1.35, 2.47) were more likely to discover pregnancy after 13 weeks.

CONCLUSION

Laws imposing gestational limits will make abortion unavailable to people who discover pregnancy after the limit. Such bans are likely to disproportionately affect people using contraceptive methods to prevent pregnancy and those who have never given birth.

IMPLICATIONS

Some pregnant people have few pregnancy symptoms and/or have conditions with symptoms similar to pregnancy, such as irregular periods or chronic pain. Gestational limits to abortion are likely to disproportionately affect people who recognize pregnancy later in pregnancy, particularly those without prior pregnancy experiences and who are using contraception.

Patient voluntarily delays call to emergency medical system for ST-elevation myocardial infarction during COVID-19 pandemic

BACKGROUND

An increase in the time from the symptoms onset to first medical contact and to primary percutaneous coronary intervention (pPCI) has been observed in countries with high-incidence of COVID-19 cases. We aimed to verify if there was any change in the patient delay and in the EMS response times up to the pPCI for STEMI patients in Swiss Ticino Canton.

METHODS

We assessed STEMI management including time from symptoms onset to EMS call, time of EMS response, time to pPCI in Swiss Canton Ticino. Data were retrieved from the Acute-Coronary-Syndrome-Ticino-Registry. We considered the patients included in the registry from March to May 2020 (pandemic period) and then from June to August 2020 (post-pandemic period) in whom a pPCI was performed. We compared these patients to those undergoing a pPCI in the same months in the year 2016-2019.

RESULTS

During the pandemic period, the time from symptoms onset to pPCI significantly increased compared to non-pandemic periods. This was due to a significant prolongation of the time from symptoms onset to EMS call, that nearly tripled. In contrast, after the pandemic period, there was a significantly shorter time from symptom onset to EMS call compared to non-pandemic years, whereas all other times remained unchanged.

CONCLUSION

Patients delay the call to EMS despite symptoms of myocardial infarction during the COVID-19 pandemic also in a region with a relatively low incidence of COVID-19.

Impact of COVID-19 on healthcare organisation and cancer outcomes

BACKGROUND

Changes in the management of patients with cancer and delays in treatment delivery during the COVID-19 pandemic may impact the use of hospital resources and cancer mortality.

PATIENTS AND METHODS

Patient flows, patient pathways and use of hospital resources during the pandemic were simulated using a discrete event simulation model and patient-level data from a large French comprehensive cancer centre's discharge database, considering two scenarios of delays: massive return of patients from November 2020 (early-return) or March 2021 (late-return). Expected additional cancer deaths at 5 years and mortality rate were estimated using individual hazard ratios based on literature.

RESULTS

The number of patients requiring hospital care during the simulation period was 13,000. In both scenarios, 6-8% of patients were estimated to present a delay of >2 months. The overall additional cancer deaths at 5 years were estimated at 88 in early-return and 145 in late-return scenario, with increased additional deaths estimated for sarcomas, gynaecological, liver, head and neck, breast cancer and acute leukaemia. This represents a relative additional cancer mortality rate at 5 years of 4.4 and 6.8% for patients expected in year 2020, 0.5 and 1.3% in 2021 and 0.5 and 0.5% in 2022 for each scenario, respectively.

CONCLUSIONS

Pandemic-related diagnostic and treatment delays in patients with cancer are expected to impact patient survival. In the perspective of recurrent pandemics or alternative events requiring an intensive use of limited hospital resources, patients should be informed not to postpone care, and medical resources for patients with cancer should be sanctuarised.
