RESUMO

Canada has one of the most complex and rigorous drug approval and public reimbursement processes and is, unfortunately, one of the countries with the longest delays in drug access. To assess the overall impact of systemic delays in access to cancer therapy, a targeted literature review (TLR) was performed to identify studies associated with the clinical, economic, and quality of life impacts of delayed access to oncology drugs. Using MEDLINE/PubMed databases and snowballing, four unique records met the eligibility criteria. Results revealed that clinical outcomes were the most impacted by systemic delays in access to oncology drugs (e.g., life years lost, overall survival, and progression-free survival). The four articles retrieved by the TLR specifically illustrated that a substantial number of life years could potentially be saved by increasing systemic efficiency regarding the development, approval, and reimbursement processes of new drugs for advanced malignancies. It is imperative that initiatives are put in place to improve the performance and speed of Canadian drug regulatory and health technology assessment (HTA) processes, especially for new cancer therapeutics. The proposed solutions in this paper include better coordination between HTA and Canadian payers to harmonize coverage decisions, international collaborations, information sharing, and national standards for timeliness in oncology drug access.

RESUMO

This research sought to assess whether and how patient preference (PP) data are currently used within health technology assessment (HTA) bodies and affiliated organizations involved in technology/drug appraisals and assessments. An exploratory survey was developed by the PP Project Subcommittee of the HTA International Patient and Citizen Involvement Interest Group to gain insight into the use, impact, and role of PP data in HTA, as well as the perceived barriers to its incorporation. Forty members of HTA bodies and affiliated organizations from twelve countries completed the online survey. PP data were reported to be formally considered as part of the HTA evidence review process by 82.5 percent of the respondents, while 39.4 percent reported that most of the appraisals and assessments within their organization in the past year had submitted PP data. The leading reason for why PP data were not submitted in most assessments was time/resource constraints followed by lack of clarity on PP data impact. Participants reported that PP data had a moderate level of influence on the deliberative process and outcome of the decision, but a higher level of influence on the decision's quality. Most (81.8 percent) felt patient advocacy groups should be primarily responsible for generating and submitting this type of evidence. Insights from the survey confirm the use of PP data in HTA but reveal barriers to its broader and more meaningful integration. Encouragingly, participants believe obstacles can be overcome, paving the way for a second phase of research involving in-depth collaborative workshops with HTA representatives.

RESUMO

The move toward early detection and treatment of cancer presents challenges for value assessment using traditional endpoints. Current cancer management rarely considers the full economic and societal benefits of therapies. Our study used a modified Delphi process to develop principles for defining and assessing value of cancer therapies that aligns with the current trajectory of oncology research and reflects broader notions of value. 24 experts participated in consensus-building activities across 5 months (16 took part in structured interactions, including a survey, plenary sessions, interviews, and off-line discussions, while 8 participated in interviews). Discussion focused on: 1) which oncology-relevant endpoints should be used for assessing treatments for early-stage cancer and access decisions for early-stage treatments, and 2) the importance of additional value components and how these can be integrated in value assessments. The expert group reached consensus on 4 principles in relation to the first area (consider oncology-relevant endpoints other than overall survival; build evidence for endpoints that provide earlier indication of efficacy; develop evidence for the next generation of predictive measures; use managed entry agreements supported by ongoing evidence collection to address decision-maker evidence needs) and 3 principles in relation to the second (routinely use patient reported outcomes in value assessments; assess broad economic impact of new medicines; consider other value aspects of relevance to patients and society).

RESUMO

Sleep difficulties are a common symptom in cancer patients at different stages of treatment trajectory and may lead to numerous negative consequences for which management is required. This pilot Randomized Controlled Trial (RCT) aims to assess the potential effectiveness of home-based prehabilitation intervention (prehab) on sleep quality and parameters compared to standard care (SOC) in colorectal cancer patients during the preoperative period and up to 8 weeks after the surgery. One hundred two participants (48.3% female, mean age 65 years) scheduled for elective resection of colorectal cancer were randomized to the prehab (n = 50) or the SOC (n = 52) groups. Recruitment and retention rates were 54% and 72%, respectively. Measures were completed at the baseline and preoperative, 4- and 8-week after-surgery follow-ups. Our mixed models' analyses revealed no significant differences between groups observed over time for all subjective and objective sleep parameters. A small positive change was observed in the perceived sleep quality only at the preoperative time point for the prehabilitation group compared to the SOC group, with an effect size d = 0.11 and a confidence interval (CI) between - 2.1 and - 0.1, p = .048. Prehab group patients with high anxiety showed a significant improvement in the rate of change of sleep duration over time compared to the SOC group, with a difference of 110 min between baseline and 8 weeks after surgery (d = 0.51, 95% CI: 92.3 to 127.7, p = .02). Multimodal prehabilitation intervention is feasible in colorectal cancer patients and may improve sleep duration for patients with high anxiety symptoms. Future large-scale RCTs are needed to confirm our results.

RESUMO

We used serial block-face scanning electron microscopy (SBF-SEM) to study the host-pathogen interface between Arabidopsis cotyledons and the hemibiotrophic fungus Colletotrichum higginsianum. By combining high-pressure freezing and freeze-substitution with SBF-SEM, followed by segmentation and reconstruction of the imaging volume using the freely accessible software IMOD, we created 3D models of the series of cytological events that occur during the Colletotrichum-Arabidopsis susceptible interaction. We found that the host cell membranes underwent massive expansion to accommodate the rapidly growing intracellular hypha. As the fungal infection proceeded from the biotrophic to the necrotrophic stage, the host cell membranes went through increasing levels of disintegration culminating in host cell death. Intriguingly, we documented autophagosomes in proximity to biotrophic hyphae using transmission electron microscopy (TEM) and a concurrent increase in autophagic flux between early to mid/late biotrophic phase of the infection process. Occasionally, we observed osmiophilic bodies in the vicinity of biotrophic hyphae using TEM only and near necrotrophic hyphae under both TEM and SBF-SEM. Overall, we established a method for obtaining serial SBF-SEM images, each with a lateral (x-y) pixel resolution of 10 nm and an axial (z) resolution of 40 nm, that can be reconstructed into interactive 3D models using the IMOD. Application of this method to the Colletotrichum-Arabidopsis pathosystem allowed us to more fully understand the spatial arrangement and morphological architecture of the fungal hyphae after they penetrate epidermal cells of Arabidopsis cotyledons and the cytological changes the host cell undergoes as the infection progresses toward necrotrophy.

RESUMO

BACKGROUND: Same-day discharge after minimally invasive colorectal surgery is a safe, effective practice in specific patients that can enhance the efficiency of enhanced recovery pathways. OBJECTIVE: To identify predictive factors associated with success or failure of same-day discharge. DESIGN: Prospective cohort study from January 2020 to March 2023. SETTINGS: Tertiary colorectal center. PATIENTS: Adult patients eligible for same-day discharge with remote postdischarge follow-up included those with minimal comorbidities, residing near the hospital, having sufficient home support, and owning a mobile device. INTERVENTIONS: Patients were discharged on the day of surgery upon meeting specific criteria, including adequate pain control, tolerance of oral intake, independent mobility, urination, and the absence of complications. Successful same-day discharge was defined as discharge on the day of surgery without unplanned visits in the first 72 hours. MAIN OUTCOME MEASURES: Factors associated with successful or failed same-day discharge after minimally invasive colorectal surgery. RESULTS: A total of 175 patients (85.3%) were discharged on the day of surgery, with 14 patients (8%) having an unplanned visit within 72 hours. Overall, 161 patients (78.5%) were categorized as same-day discharge success and 44 patients (21.5%) as same-day discharge failure. The same-day discharge failure group had a higher Charlson Comorbidity Index (3.7 vs 2.8, p = 0.03). Mean length of stay (0.8 vs 3.0, p = 0.00), 30-day complications (10% vs 48%, p = 0.00), and readmissions (8% vs 27%, p = 0.00) were higher in the same-day discharge failure group. Regression analysis showed that failed same-day discharge was associated with higher comorbidities (OR 0.79; 95% CI, 0.66-0.95) and prolonged postanesthesia care unit time (OR 0.99; 95% CI, 0.99-0.99). Individuals who received a regional nerve block (OR 4.1; 95% CI, 1.2-14) and those who did not consume postoperative opioids (OR 4.6; 95% CI, 1-21) were more likely to have successful same-day discharge. LIMITATIONS: Single-center study. CONCLUSIONS: Our findings indicate that comorbidities and prolonged postanesthesia care unit stays were associated with same-day discharge failure, whereas regional nerve blocks and minimal postoperative opioids were related to success. These factors may inform future research aiming to enhance colorectal surgery recovery protocols. See Video Abstract . FACTORES PREDICTIVOS PARA UN ALTA EXITOSA EL MISMO DA DESPUS DE UNA COLECTOMA MNIMAMENTE INVASIVA Y REVERSIN DEL ESTOMA: ANTECEDENTES:El alta el mismo día después de una cirugía colorrectal mínimamente invasiva es una práctica segura y eficaz en pacientes específicos que puede mejorar la eficiencia de las vías de recuperación mejoradas.OBJETIVO:Identificar factores predictivos asociados con el éxito o fracaso del alta el mismo día.DISEÑO:Estudio de cohorte prospectivo del 01/2020 al 03/2023.AJUSTES:Centro colorrectal terciario.PACIENTES:Los pacientes adultos elegibles para el alta el mismo día con seguimiento remoto posterior al alta incluyeron aquellos con comorbilidades mínimas, que residían cerca del hospital, tenían suficiente apoyo en el hogar y poseían un dispositivo móvil.INTERVENCIONES:Los pacientes fueron dados de alta el día de la cirugía al cumplir con criterios específicos, incluido un control adecuado del dolor, tolerancia a la ingesta oral, movilidad independiente, micción y ausencia de complicaciones. El alta exitosa el mismo día se definió como el alta el día de la cirugía sin visitas no planificadas en las primeras 72 horas.PRINCIPALES MEDIDAS DE RESULTADO:Factores asociados con el alta exitosa o fallida el mismo día después de una cirugía colorrectal mínimamente invasiva.RESULTADOS:Un total de 175 (85,3%) pacientes fueron dados de alta el día de la cirugía y 14 (8%) pacientes tuvieron una visita no planificada dentro de las 72 horas. En total, 161 (78,5%) pacientes se clasificaron como éxito del alta el mismo día y 44 (21,5%) pacientes como fracaso del alta el mismo día. El grupo de fracaso del alta el mismo día tuvo un índice de comorbilidad de Charlson más alto (3,7, 2,8, p = 0,03). La duración media de la estancia hospitalaria (0,8, 3,0, p = 0,00), las complicaciones a los 30 días (10%, 48%, p = 0,00) y los reingresos (8%, 27%, p = 0,00) fueron mayores en el mismo día grupo de fallo de descarga. El análisis de regresión mostró que el alta fallida el mismo día se asoció con mayores comorbilidades (OR 0,79; IC del 95 %: 0,66; 0,95) y tiempo prolongado en la unidad de cuidados postanestésicos (OR 0,99; IC del 95 %: 0,99; 0,99). Las personas que recibieron un bloqueo nervioso regional (OR 4,1; IC del 95 %: 1,2, 14) y aquellos que no consumieron opioides posoperatorios (OR 4,6, IC del 95 %: 1-21) tuvieron más probabilidades de tener éxito en el mismo día -descarga.LIMITACIONES:Estudio unicéntrico.CONCLUSIONES:Nuestros hallazgos indican que las comorbilidades y las estancias prolongadas en la unidad de cuidados postanestésicos se asociaron con el fracaso del alta el mismo día, mientras que los bloqueos nerviosos regionales y los opioides postoperatorios mínimos se relacionaron con el éxito. Estos factores pueden informar investigaciones futuras destinadas a mejorar los protocolos de recuperación de la cirugía colorrectal. (Traducción-Yesenia Rojas-Khalil ).

RESUMO

BACKGROUND: Low patient activation (PA) is associated with worse postoperative outcomes, however, its impact on the effectiveness of digital health interventions is unknown. We sought to determine the impact of PA on the effectiveness of digital health application for remote post-discharge follow-up for patients undergoing elective colectomy. METHODS: Data analysis included a control cohort (CC) of patients undergoing elective colorectal surgery from 10/2017 to 04/2018 without the digital health intervention and a digital application cohort (DAC) that received a smart phone application for remote post-discharge follow-up from 03/2021 to 08/2022, including a subset of same-day discharge (SDD) patients. PA was measured using the Patient Activation Measure (PAM; score 0-100) and categorized into low (< 55.1) and high (≥ 55.1). The PAM was administered 4-6 weeks before surgery in the DAC group and on postoperative day (POD) 1 in the CC group. The main outcome measure was 30-day emergency department (ED) visits. RESULTS: A total of 164 patients were included (89DAC with 50 SDD, 75CC), with no differences in patient characteristics other than more stoma closures in the DAC group. Overall, 77% of patients had high PA level, with no difference between CC and DAC (77% vs. 81%, p = 0.25). There was no difference in ED visits between CC and DAC (19% vs. 18%, p = 0.90). Overall, low PA was associated more ED visits (29% vs 14%, p = 0.04). In the SDD subgroup, low PA patients had more ED visits (38% vs. 7%, p = 0.015). PA level did not affect app usage metrics. On multiple regression, only low PA remained independently associated with ED visits (OR 3.42, 95%CI 1.27, 9.24). CONCLUSION: Low PA remains an important predictor of surgical outcomes after elective colorectal surgery regardless of the use of a digital health application for remote post-discharge follow-up. This suggests that improving PA levels may improve postoperative outcomes.

RESUMO

The COVID-19 pandemic caused disruptions in colorectal cancer (CRC) care by interrupting CRC screening across Canada, posing problems for program participants, patients, and physicians and no clear understanding of how provincial healthcare systems would adapt in the face of another pandemic or shock to the system. A nationwide online survey targeted to members of the National Colorectal Cancer Screening Network (NCCSN) using the SurveyMonkey platform was conducted to gain insight into the impact of the pandemic on CRC screening from March 2020 to March 2022 across all thirteen Canadian jurisdictions. The survey included 25 multiple-choice and free-text questions. Both quantitative and qualitative methods were used to analyze the data using Microsoft Excel and NVivo software. Twenty-one provincial and territorial representatives participated in the survey conducted between 13 May 2022 and 27 October 2022. All jurisdictions (100%) reported decreased screenings, including fecal immunochemical testing (FIT) or Fecal Occult Blood testing (FOBT) procedures, and subsequent diagnostic colonoscopies. The average wait time for colonoscopies due to a positive FIT/FOBT was 76 days. To mitigate the backlog and initiate an effective intervention plan, representatives highlighted some key points, including the importance of prioritizing high-risk patients. Survey results concluded that the COVID-19 pandemic impacted CRC screening across Canada. This landscape assessment can help inform intervention measures and policy-related solutions to create greater resilience for CRC screening in provincial and territorial healthcare systems.

RESUMO

Hemianopia is a common consequence of unilateral damage to visual cortex that manifests as a profound blindness in contralesional space. A noninvasive cross-modal (visual-auditory) exposure paradigm has been developed in an animal model to ameliorate this disorder. Repeated stimulation of a visual-auditory stimulus restores overt responses to visual stimuli in the blinded hemifield. It is believed to accomplish this by enhancing the visual sensitivity of circuits remaining after a lesion of visual cortex; in particular, circuits involving the multisensory neurons of the superior colliculus. Neurons in this midbrain structure are known to integrate spatiotemporally congruent visual and auditory signals to amplify their responses, which, in turn, enhances behavioral performance. Here we evaluated the relationship between the rehabilitation of hemianopia and this process of multisensory integration. Induction of hemianopia also eliminated multisensory enhancement in the blinded hemifield. Both vision and multisensory enhancement rapidly recovered with the rehabilitative cross-modal exposures. However, although both reached pre-lesion levels at similar rates, they did so with different spatial patterns. The results suggest that the capability for multisensory integration and enhancement is not a pre-requisite for visual recovery in hemianopia, and that the underlying mechanisms for recovery may be more complex than currently appreciated.

RESUMO

The multisensory (deep) layers of the superior colliculus (SC) play an important role in detecting, localizing, and guiding orientation responses to salient events in the environment. Essential to this role is the ability of SC neurons to enhance their responses to events detected by more than one sensory modality and to become desensitized ('attenuated' or 'habituated') or sensitized ('potentiated') to events that are predictable via modulatory dynamics. To identify the nature of these modulatory dynamics, we examined how the repetition of different sensory stimuli affected the unisensory and multisensory responses of neurons in the cat SC. Neurons were presented with 2HZ stimulus trains of three identical visual, auditory, or combined visual-auditory stimuli, followed by a fourth stimulus that was either the same or different ('switch'). Modulatory dynamics proved to be sensory-specific: they did not transfer when the stimulus switched to another modality. However, they did transfer when switching from the visual-auditory stimulus train to either of its modality-specific component stimuli and vice versa. These observations suggest that predictions, in the form of modulatory dynamics induced by stimulus repetition, are independently sourced from and applied to the modality-specific inputs to the multisensory neuron. This falsifies several plausible mechanisms for these modulatory dynamics: they neither produce general changes in the neuron's transform, nor are they dependent on the neuron's output.

RESUMO

Hemianopia (unilateral blindness), a common consequence of stroke and trauma to visual cortex, is a debilitating disorder for which there are few treatments. Research in an animal model has suggested that visual-auditory stimulation therapy, which exploits the multisensory architecture of the brain, may be effective in restoring visual sensitivity in hemianopia. It was tested in two male human patients who were hemianopic for at least 8 months following a stroke. The patients were repeatedly exposed to congruent visual-auditory stimuli within their blinded hemifield during 2 h sessions over several weeks. The results were dramatic. Both recovered the ability to detect and describe visual stimuli throughout their formerly blind field within a few weeks. They could also localize these stimuli, identify some of their features, and perceive multiple visual stimuli simultaneously in both fields. These results indicate that the multisensory therapy is a rapid and effective method for restoring visual function in hemianopia.SIGNIFICANCE STATEMENT Hemianopia (blindness on one side of space) is widely considered to be a permanent disorder. Here, we show that a simple multisensory training paradigm can ameliorate this disorder in human patients.

RESUMO

BACKGROUND: Treatment of rectal cancer is frequently associated with low anterior resection syndrome. However, data concerning the contribution rectal tumors have on pretreatment bowel-dysfunction is scarce. We sought to evaluate the impact of the untreated rectal cancer on bowel-dysfunction and the relationship of pretreatment and post-treatment function. METHODS: A prospective database of adults with rectal cancer at a single university-affiliated colorectal referral center from August 2018 to March 2022 was queried. Bowel-dysfunction was measured using the low anterior resection syndrome score questionnaire (categorized as no, minor, or major low anterior resection syndrome) which was provided to patients at their primary visit, and after treatment. Patients were included if they underwent rectal cancer treatment and had pre- and post-treatment low anterior resection syndrome measurements. Observed low anterior resection syndrome scores were compared to normative low anterior resection syndrome data for age and sex-specific distributions from published data. Multiple multinomial regression compared pre- and post-treatment low anterior resection syndrome scores. RESULTS: Overall, 121 patients were included with mean age 62.0 years (standard deviation 12.3), 74% male, and mean tumor height 8.7 cm (standard deviation 5.72). The proportion of pretreatment observed low anterior resection syndrome were 48% no low anterior resection syndrome, 28% minor, and 24% major. Male and older patients were more likely to have worse than predicted low anterior resection syndrome categories (P < .05). On average, low anterior resection syndrome category did not change after treatment (P = .618) and pretreatment low anterior resection syndrome category was a significant independent predictor of post-treatment category (P = .037). CONCLUSION: Pretreatment bowel-dysfunction in rectal cancer patients is common and significantly worse than predicted for older and male patients. Importantly, pretreatment bowel-dysfunction predicted postoperative function. These results may better inform the shared decision-making process.

RESUMO

BACKGROUND: There is increasing evidence to support discharge prior to gastrointestinal recovery following colorectal surgery. Furthermore, many patients are discharged early despite being excluded from an ambulatory colectomy pathway. The objective of this study was to determine the outcomes of patients discharged early following laparoscopic colectomy in an enhanced recovery pathway (ERP). METHODS: A retrospective review of all adult patients undergoing elective laparoscopic colectomy at a single university-affiliated colorectal referral center (08/2017-06/2021) was performed. Patients were included if they had undergone elective laparoscopic colectomy or ileostomy closure and excluded if they had been enrolled in an ambulatory colectomy pathway. Patients were then divided into three groups: LOS =1 day, LOS 2-3 days, and LOS 4+ days. The main outcomes were 30-day emergency room (ER) visits and readmissions. Reasons for inpatient stay per post-operative day (POD) were also recorded. RESULTS: A total of 497 patients were included [LOS1 n = 63 (13%), LOS2-3 n = 284 (57%), and LOS4+ n = 150 (30%)]. There were no differences in patient characteristics, diagnosis, or procedure between the groups. Patients were discharged with gastrointestinal recovery (GI-3) in 54% LOS1 vs. 98% LOS2-3 vs. 100% LOS4+ (p<0.001). Shorter procedure duration, transversus abdominus plane block, and lower opioid requirements were associated with shorter LOS (p<0.001). The absence of flatus was the most common reason to keep patients hospitalized: 61% on POD1, 21% on POD2, and 8% on POD3 (p<0.001). There were no differences in 30-day emergency visits, or readmission between the groups. In the LOS1 group, there were no differences in outcomes between patients with full return of bowel function at discharge compared to those without. CONCLUSION: Discharge on POD1 was not associated with increased emergency department use, complications, or readmissions. Importantly, full return of bowel function at discharge did not affect outcomes. There may be potential to expand eligibility criteria for ambulatory colectomy protocol.

RESUMO

Concordant visual-auditory stimuli enhance the responses of individual superior colliculus (SC) neurons. This neuronal capacity for "multisensory integration" is not innate: it is acquired only after substantial cross-modal (e.g. auditory-visual) experience. Masking transient auditory cues by raising animals in omnidirectional sound ("noise-rearing") precludes their ability to obtain this experience and the ability of the SC to construct a normal multisensory (auditory-visual) transform. SC responses to combinations of concordant visual-auditory stimuli are depressed, rather than enhanced. The present experiments examined the behavioral consequence of this rearing condition in a simple detection/localization task. In the first experiment, the auditory component of the concordant cross-modal pair was novel, and only the visual stimulus was a target. In the second experiment, both component stimuli were targets. Noise-reared animals failed to show multisensory performance benefits in either experiment. These results reveal a close parallel between behavior and single neuron physiology in the multisensory deficits that are induced when noise disrupts early visual-auditory experience.

RESUMO

BACKGROUND: Emergency visits after colorectal surgery are common and require significant health care resources. However, many visits may be avoidable with alternative access to care. Mobile health technologies can facilitate patient access to health care providers. OBJECTIVE: We hypothesized that a mobile app for postdischarge monitoring with patient-provider communication ability would reduce emergency visits after elective abdominopelvic colorectal surgery. DESIGN: This is a prospective cohort study with a regression analysis after coarsened exact matching. SETTING: The study was conducted at a single colorectal referral center from May 2019 to September 2020. PATIENTS: A total of 114 patients were recruited to the intervention and were matched to a retrospective cohort of 608 patients from the 24 months before the study. All patients were managed according to an enhanced recovery pathway. INTERVENTIONS: A mobile phone app comprised of patient education material, daily questionnaires assessing postdischarge recovery, and patient-provider chat function was used. MAIN OUTCOME MEASURES: The primary outcomes included potentially preventable 30-day emergency visits defined according to a validated algorithm. Secondary outcomes included length of stay, complications, total emergency department visits, readmissions, and app usability. RESULTS: Coarsened-exact matching resulted in a matched sample of 94 prospective intervention patients and 256 retrospective control patients. The prospective group was associated with fewer preventable emergency department visits (incidence rate ratio 0.34; p = 0.043) and shorter length of stay (-1.62 days; p = 0.011). There were no differences in 30-day complications, total number of emergency visits, or readmissions. Patient-reported usability of the mobile app was high, with 88% of patients reporting that the app improved their ability to communicate with their surgeon. LIMITATIONS: We did not account for patient activation or perform a cost-analysis. CONCLUSION: Use of a mobile app was associated with fewer potentially preventable emergency visits and shorter length of stay after major elective colorectal surgery, which may be due to enhanced postdischarge monitoring and patient-provider communication.

APLICACIN DE TELFONO MVIL MEJORA LA COMUNICACIN ENTRE MDICO Y PACIENTE Y REDUCE LAS VISITAS AL DEPARTAMENTO DE EMERGENCIAS DESPUS DE CIRUGA COLORECTAL: ANTECEDENTES:Las visitas de emergencia después de la cirugía colorrectal son frecuentes y requieren importantes recursos sanitarios. Sin embargo, muchas visitas pueden evitarse con un acceso alternativo a la atención. Las tecnologías de salud móviles pueden facilitar el acceso de los pacientes a los proveedores de atención médica.OBJETIVO:Se planteó la hipótesis de que una aplicación móvil para el seguimiento posterior al alta con capacidad de comunicación entre el paciente y el médico reduciría las visitas de emergencia después de cirugía colorrectal abdominopélvica electiva.DISEÑO:Este es un estudio de cohorte prospectivo con un análisis de regresión después de un emparejamiento exacto aproximado.ENTORNO CLINICO:El estudio se llevó a cabo en un solo centro de referencia colorrectal entre 05/2019 y 09/2020.PACIENTES:Se reclutó un total de 114 pacientes para la intervención y se emparejaron con una cohorte retrospectiva de 608 pacientes de los 24 meses anteriores al estudio. Todos los pacientes fueron tratados con protocolo de enhanced recovery .INTERVENCIONES:Se utilizó una aplicación para teléfono móvil compuesta de material educativo para el paciente, cuestionarios diarios que evalúan la recuperación posterior al alta y una función de chat entre el paciente y el médico.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados primarios incluyeron visitas a la emergencia en 30 días potencialmente prevenibles, definidas según un algoritmo validado. Los resultados secundarios incluyeron la duración de la estancia, complicaciones, total de visitas al departamento de emergencias, reingresos y la usabilidad de la aplicación.RESULTADOS:El emparejamiento aproximado-exacto resultó en una muestra emparejada de 94 APP + y 256 APP-. APP + se asoció con menos visitas evitables al servicio de urgencias (IRR 0,34, p = 0,043) y una estancia más corta (-1,62 días, p = 0,011). No hubo diferencias en las complicaciones a los 30 días, número total de visitas de emergencia y reingresos. La usabilidad de la aplicación móvil informada por los pacientes fue alta, y el 88% de los pacientes informaron que la aplicación mejoró su capacidad para comunicarse con su cirujano.LIMITACIONES:No contabilizamos la activación del paciente ni realizamos un análisis de costos.CONCLUSIÓNES:El uso de una aplicación móvil se asoció con menos visitas a la emergencia potencialmente prevenibles y una estadía más corta después de una gran cirugía colorrectal electiva, lo que puede deberse a una mejor monitorización posterior al alta y a la comunicación entre el paciente y el médico.

RESUMO

Bacillus mycoides Ko01 strain grows rapidly and forms extensive rhizoidal colonies on hard agar despite limited surface water availability. The agar concentrations affect the handedness of the colonies as well as other colony architectures. In this study, we found that the local curvature of cell chains in the developing colonies did not vary based on the agar concentration, while concentration does affect the handedness of chirality at the macroscale. This result suggests independence between the microscale filament curvature and macroscale colony chirality. In addition, we discovered a novel microscopic property of cells that has not been observed before: T-shaped budding under extremely low surface water availability conditions. We propose that this feature gives rise to chaotic colony morphology. Together with bundling of chains, cells form a unique set of spatial arrangements under different surface water availability. These properties appear to impact the structural features of thick tendrils, and thereby the overall morphology of colonies. Our study provides additional insights as to how bacteria proliferate, spread, and develop macroscale colony architecture under water-limited conditions.

RESUMO

BACKGROUND: Colorectal cancer, one of the most commonly diagnosed cancers, is now being detected earlier and treatments are improving, which means that patients are living longer. Partnering with Canadian clinicians, patients and researchers, we aimed to determine research priorities for those living with early-stage colorectal cancer in Canada. METHODS: We followed the well-established priority-setting partnership outlined by the James Lind Alliance to identify and prioritize unanswered questions about early-stage (i.e., stages I-III) colorectal cancer. The study was conducted from September 2018 to September 2020. We surveyed patients, caregivers and clinicians from across Canada between June 2019 and December 2019. We categorized the responses using thematic analysis to generate a list of unique questions. We conducted an interim prioritization survey from April 2020 to July 2020, with patients, caregivers and clinicians, to determine a shorter list of questions, which was then reviewed at a final meeting (involving patients, caregivers and clinicians) in September 2020. At that meeting, we used a consensus-based process to determine the top 10 priorities. RESULTS: For the initial survey, 370 responses were submitted by 185 individuals; of the 98 individuals who provided demographic information, 44 (45%) were patients, 16 (16%) were caregivers, 7 (7%) were members of an advocacy group, 26 (27%) were health care professionals and 5 (5%) were categorized as "other." The responses were refined to create a list of 66 unique unanswered questions. Twenty-five respondents answered the interim prioritization survey: 13 patients (52%), 2 caregivers (8%), 3 advocacy group members (12%) and 7 health care professionals (28%). This led to a list of the top 30 questions. The final consensus meeting involved 20 individuals (10 patients [50%], 3 caregivers [15%] and 7 health care professionals [35%]), who agreed to the top 10 research priorities. The priorities covered a range of topics, including screening, treatment, recurrence, management of adverse effects and decision-making. INTERPRETATION: We determined the top research priorities for early-stage colorectal cancer using a collaborative partnership of stake-holders from across Canada. The priorities covered a broad range of topics that could be addressed by future research, including improved screening practices, the role of personalized medicine, the management of adverse effects of treatment, decision-making and prevention of recurrence.

RESUMO

(1) Background: The COVID-19 pandemic illuminated vulnerabilities in the Canadian health care system and exposed gaps and challenges across the cancer care continuum. Canada is experiencing significant disruptions to cancer-related services, and the impact these disruptions (delays/deferrals/cancellations) have on the health care system and patients are yet to be determined. Given the potential adverse ramifications, how can Canada's health care systems build resilience for future threats? (2) Methods: To answer this question, CCC facilitated a series of four thought-leadership roundtables, each representing the views of four different stakeholder groups: patients, physicians, health care system leaders, and researchers. (3) Results: Six themes of strength were identified to serve as a springboard for building resilience including, (1) advancing virtual care and digital health technologies to prevent future interruptions in cancer care delivery. (2) developing real-time data metrics, data sharing, and evidence-based decision-making. (3) enhancing public-private-non-profit partnerships to advance research and strengthen connections across the system. (4) advancing patient-centricity in cancer research to drive and encourage precision medicine approaches to care. (5) investing in training and hiring a robust supply of health care human resources. (6) implementing a national strategy and infrastructure to ensure inter-provincial collaborative data sharing (4). Conclusions: A resilient health care system that can respond to shocks and threats is not an emergency system; it is a robust everyday system that can respond to emergencies.

RESUMO

INTRODUCTION: A high proportion of colorectal surgery patients within an enhanced recovery pathway (ERP) do not experience complications but remain hospitalized mainly waiting for gastrointestinal (GI) recovery. Accurate identification of these patients may allow discharge prior to the return of GI function. Therefore, the objective of this study is to determine if tolerating clear fluid (CF) on postoperative day (POD) 0 was associated with uncomplicated return of GI function after laparoscopic colorectal surgery. METHODS: Pooled data from three prospective studies from a single specialist colorectal referral center were analyzed (2013-2019). The present study included adult patients that underwent elective laparoscopic colectomy without stoma. Postoperative GI symptoms were collected daily in all three datasets. The main exposure variable, whether CF diet was tolerated on POD0, was defined as patients drinking at least 300 mL of CF without any nausea, anti-emetics, or vomiting (CF+ vs CF-). The main outcome measure was time to GI-3 (tolerating solid diet and passage of gas or stools). RESULTS: A total of 221 patients were included in this study, including 69% CF+ and 31% CF-. The groups were similar in age, gender, and comorbidities, but the CF- patients were more likely to have surgery for inflammatory bowel disease. CF+ patients had faster time to GI-3 (mean 1.6d (SD 0.7) vs. 2.3d (SD 1.5), p < 0.001). The CF+ group also experienced fewer complications (19% vs. 35%, p = 0.009), shorter mean LOS (mean 3.6d (SD 2.9) vs. 6.2d (SD 9.4), p = 0.002), and were more likely to be discharged by the target LOS (66% vs. 50%, p = 0.024). CONCLUSION: Toleration of CF on POD0 was associated with faster return of GI function, fewer complications, and shorter LOS. This may be used as a criteria for potential discharge prior to full return of GI function after laparoscopic colectomy within an ERP.

RESUMO

OBJECTIVE: To investigate the feasibility of SDD protocol with postdischarge follow-up using a mobile phone app in patients undergoing elective minimally-invasive colectomy. SUMMARY OF BACKGROUND DATA: Discharge before gastrointestinal recovery and use of mobile health technology for remote follow-up may allow for SDD after minimally-invasive colectomy within an ERP. METHODS: Adult patients undergoing elective laparoscopic colectomy or loop ileostomy reversal from February 2020 to November 2020 were screened for eligibility. Patients were eligible if they lived within a 30-minute drive from the hospital, had an adequate support system at home, and owned a smart phone. Patients were discharged from the recovery room on the day of surgery based on set criteria with postdischarge remote follow-up using a mobile application. Feasibility was defined as discharge on the day of surgery without emergency department (ED) visit or readmission within the first 3 days. 30-day complications, ED visits, and readmissions were compared to a non-SDD historical cohort (May 2019-March 2020) also remotely followed-up using the same mobile phone app (standard ERP group). RESULTS: A total of 48 patients were recruited to SDD, of which 77% were discharged on the day of surgery without subsequent ED visit in the first 72 hours. There were 11 patients that could not be discharged, including 7 for failure of discharge criteria and 4 for intraoperative complications/concerns. Overall 30-day complications in the SDD group (17%) was similar to the standard ERP group (15%, P = 0.813). ED visits (SDD10% vs standard ERP8%, P = 0.664) and readmissions (6% vs 4%, P = 0.681) were also similar. CONCLUSIONS AND RELEVANCE: Findings from this study support the feasibility of a SDD protocol in select patients undergoing minimally-invasive colorectal resection. SDD colectomy protocols may represent the next evolution of ERP and postoperative recovery.
