Code ICH: A Call to Action.

Intracerebral hemorrhage is the most serious type of stroke, leading to high rates of severe disability and mortality. Hematoma expansion is an independent predictor of poor functional outcome and is a compelling target for intervention. For decades, randomized trials aimed at decreasing hematoma expansion through single interventions have failed to meet their primary outcomes of statistically significant improvement in neurological outcomes. A wide range of evidence suggests that ultra-early bundled care, with multiple simultaneous interventions in the acute phase, offers the best hope of limiting hematoma expansion and improving functional recovery. Patients with intracerebral hemorrhage who fail to receive early aggressive care have worse outcomes, suggesting that an important treatment opportunity exists. This consensus statement puts forth a call to action to establish a protocol for Code ICH, similar to current strategies used for the management of acute ischemic stroke, through which early intervention, bundled care, and time-based metrics have substantially improved neurological outcomes. Based on current evidence, we advocate for the widespread adoption of an early bundle of care for patients with intracerebral hemorrhage focused on time-based metrics for blood pressure control and emergency reversal of anticoagulation, with the goal of optimizing the benefit of these already widely used interventions. We hope Code ICH will endure as a structural platform for continued innovation, standardization of best practices, and ongoing quality improvement for years to come.

Standardizing the estimation of ischemic regions can harmonize CT perfusion stroke imaging.

OBJECTIVES: We aimed to evaluate the real-world variation in CT perfusion (CTP) imaging protocols among stroke centers and to explore the potential for standardizing vendor software to harmonize CTP images. METHODS: Stroke centers participating in a nationwide multicenter healthcare evaluation were requested to share their CTP scan and processing protocol. The impact of these protocols on CTP imaging was assessed by analyzing data from an anthropomorphic phantom with center-specific vendor software with default settings from one of three vendors (A-C): IntelliSpace Portal, syngoVIA, and Vitrea. Additionally, standardized infarct maps were obtained using a logistic model. RESULTS: Eighteen scan protocols were studied, all varying in acquisition settings. Of these protocols, seven, eight, and three were analyzed with center-specific vendor software A, B, and C respectively. The perfusion maps were visually dissimilar between the vendor software but were relatively unaffected by the acquisition settings. The median error [interquartile range] of the infarct core volumes (mL) estimated by the vendor software was - 2.5 [6.5] (A)/ - 18.2 [1.2] (B)/ - 8.0 [1.4] (C) when compared to the ground truth of the phantom (where a positive error indicates overestimation). Taken together, the median error [interquartile range] of the infarct core volumes (mL) was - 8.2 [14.6] before standardization and - 3.1 [2.5] after standardization. CONCLUSIONS: CTP imaging protocols varied substantially across different stroke centers, with the perfusion software being the primary source of differences in CTP images. Standardizing the estimation of ischemic regions harmonized these CTP images to a degree. CLINICAL RELEVANCE STATEMENT: The center that a stroke patient is admitted to can influence the patient's diagnosis extensively. Standardizing vendor software for CT perfusion imaging can improve the consistency and accuracy of results, enabling a more reliable diagnosis and treatment decision. KEY POINTS: • CT perfusion imaging is widely used for stroke evaluation, but variation in the acquisition and processing protocols between centers could cause varying patient diagnoses. • Variation in CT perfusion imaging mainly arises from differences in vendor software rather than acquisition settings, but these differences can be reconciled by standardizing the estimation of ischemic regions. • Standardizing the estimation of ischemic regions can improve CT perfusion imaging for stroke evaluation by facilitating reliable evaluations independent of the admission center.

Does Examination Table Paper Use Mitigate the Risk of Disease Transmission in a Family Medicine Clinic?

Reducing examination table paper (ETP) use may help curb carbon emissions from health care. Six participants applied Glo Germ (DMA International) to their hands before a common physical examination (abdominal, cardiorespiratory, hip and knee) both with and without ETP. After each exam, UV light was shined on the exam table and photographs were taken. The number of hand touches on ETP-covered areas and uncovered areas were tallied and compared using t tests. Despite covering more surface area, participants touched areas without ETP significantly more than ETP-covered areas (P <.05). Despite its continued use, patients do not have much hand contact with ETP during common clinical examinations.

Code-ICH: A New Paradigm for Emergency Intervention.

PURPOSE OF REVIEW: Intracerebral hemorrhage (ICH) is the most devastating type of stroke, causing widespread disability and mortality. Unfortunately, the acute care of ICH has lagged behind that of ischemic stroke. There is an increasing body of evidence supporting the importance of early interventions including aggressive control of blood pressure and reversal of anticoagulation in the initial minutes to hours of presentation. This review highlights scientific evidence behind a new paradigm to care for these patients called Code-ICH. RECENT FINDINGS: While numerous trials aimed at decreasing hematoma expansion through single interventions had failed to show statistically significant effects on primary outcomes, time-sensitive, multifaceted, bundled care approaches have recently shown substantial promise in improving functional outcomes in patients with ICH. The concept of Code-ICH can serve as a structural platform for the practice of acute care neurology to continuously measure its performance, reflect on best practices, advance care, and address disparities.

Executive Summary: International Clinical Practice Guidelines for Pediatric Ventilator Liberation, A Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network Document.

Rationale: Pediatric-specific ventilator liberation guidelines are lacking despite the many studies exploring elements of extubation readiness testing. The lack of clinical practice guidelines has led to significant and unnecessary variation in methods used to assess pediatric patients' readiness for extubation. Methods: Twenty-six international experts comprised a multiprofessional panel to establish pediatrics-specific ventilator liberation clinical practice guidelines, focusing on acutely hospitalized children receiving invasive mechanical ventilation for more than 24 hours. Eleven key questions were identified and first prioritized using the Modified Convergence of Opinion on Recommendations and Evidence. A systematic review was conducted for questions that did not meet an a priori threshold of ⩾80% agreement, with Grading of Recommendations, Assessment, Development, and Evaluation methodologies applied to develop the guidelines. The panel evaluated the evidence and drafted and voted on the recommendations. Measurements and Main Results: Three questions related to systematic screening using an extubation readiness testing bundle and a spontaneous breathing trial as part of the bundle met Modified Convergence of Opinion on Recommendations criteria of ⩾80% agreement. For the remaining eight questions, five systematic reviews yielded 12 recommendations related to the methods and duration of spontaneous breathing trials, measures of respiratory muscle strength, assessment of risk of postextubation upper airway obstruction and its prevention, use of postextubation noninvasive respiratory support, and sedation. Most recommendations were conditional and based on low to very low certainty of evidence. Conclusions: This clinical practice guideline provides a conceptual framework with evidence-based recommendations for best practices related to pediatric ventilator liberation.

Implementation of an adapted perioperative ventriculoperitoneal shunting protocol in a tertiary center located in a low-to-middle-income country.

OBJECTIVE: Preventative protocols have efficaciously reduced shunt infection in developed countries. However, the generalizability of these protocols in low-to-middle-income countries (LMICs) remains unclear. Previously, shunt insertion in the authors' center was routinely performed under institutional preventative precautions, which was updated via merging with the Hydrocephalus Clinical Research Network (HCRN) protocol. This study aimed to investigate the ventriculoperitoneal shunt (VPS) infection rates in pediatric patients following the implementation of the adapted protocol. METHODS: The adapted protocol was implemented in all first-time VPS implantations between 2011 and 2021. The primary outcome was a 6-month shunt infection. The Pearson chi-square test was used for categorical variables and the Mann-Whitney U-test for numeric variables to evaluate the correlation with shunt infection. RESULTS: A total of 352 first-time VPS procedures were performed adhering to the adapted protocol. The median age was 5 months, and 189 (53.7%) were male. Overall, 37 patients (10.5%) experienced shunt infection, with 30 (8.5%) occurring within the first 6 months, which was lower than 13.3% infection rate of the previous series of the same center. The infection rate was slightly higher than the 5.7% and 6.0% rates reported by HCRN studies. Patients with shunt infection were significantly younger (7.5 versus 17.5 months, P < 0.001). CONCLUSIONS: This study validates the efficacy of an adapted perioperative protocol in mitigating shunt infection in a high-volume center in a LMIC. Adhering to a step-by-step protocol, modified to suit the healthcare resources and financial constraints of LMICs, could maintain low shunt infection rates that are roughly comparable to those of centers in high-income countries.

The Quality in Acute Stroke Care (QASC) global scale-up using a cascading facilitation framework: a qualitative process evaluation.

BACKGROUND: Variation in hospital stroke care is problematic. The Quality in Acute Stroke (QASC) Australia trial demonstrated reductions in death and disability through supported implementation of nurse-led, evidence-based protocols to manage fever, hyperglycaemia (sugar) and swallowing (FeSS Protocols) following stroke. Subsequently, a pre-test/post-test study was conducted in acute stroke wards in 64 hospitals in 17 European countries to evaluate upscale of the FeSS Protocols. Implementation across countries was underpinned by a cascading facilitation framework of multi-stakeholder support involving academic partners and a not-for-profit health organisation, the Angels Initiative (the industry partner), that operates to promote evidence-based treatments in stroke centres. .We report here an a priori qualitative process evaluation undertaken to identify factors that influenced international implementation of the FeSS Protocols using a cascading facilitation framework. METHODS: The sampling frame for interviews was: (1) Executives/Steering Committee members, consisting of academics, the Angels Initiative and senior project team, (2) Angel Team leaders (managers of Angel Consultants), (3) Angel Consultants (responsible for assisting facilitation of FeSS Protocols into multiple hospitals) and (4) Country Co-ordinators (senior stroke nurses with country and hospital-level responsibilities for facilitating the introduction of the FeSS Protocols). A semi-structured interview elicited participant views on the factorsthat influenced engagement of stakeholders with the project and preparation for and implementation of the FeSS Protocol upscale. Interviews were recorded, transcribed verbatim and analysed inductively within NVivo. RESULTS: Individual (n = 13) and three group interviews (3 participants in each group) were undertaken. Three main themes with sub-themes were identified that represented key factors influencing upscale: (1) readiness for change (sub-themes: negotiating expectations; intervention feasible and acceptable; shared goal of evidence-based stroke management); (2) roles and relationships (sub-themes: defining and establishing roles; harnessing nurse champions) and (3) managing multiple changes (sub-themes: accommodating and responding to variation; more than clinical change; multi-layered communication framework). CONCLUSION: A cascading facilitation model involving a partnership between evidence producers (academic partners), knowledge brokers (industry partner, Angels Initiative) and evidence adopters (stroke clinicians) overcame multiple challenges involved in international evidence translation. Capacity to manage, negotiate and adapt to multi-level changes and strategic engagement of different stakeholders supported adoption of nurse-initiated stroke protocols within Europe. This model has promise for other large-scale evidence translation programs.

Methodological Procedures to Acquire and Analyze Ultrasound Images of Swallowing: A Scoping Review.

This scoping review aimed to identify methodological procedures for acquiring and analyzing ultrasound images related to swallowing in adults and older adults. The inclusion criteria were based on the PCC strategy (participants, concept, and context), as follows: population (adults and older adults), concept (ultrasound assessment), and context (swallowing assessment). The review included observational, experimental, descriptive, and analytical studies and excluded those that were not available in full, animal studies, in vitro studies, letters to the editor, errata, study protocols, and those that used ultrasound for purposes other than swallowing. There were no language and time restrictions. Two independent blinded professionals selected 81 articles that met the inclusion criteria from different databases. The most evaluated parameters included tongue morphology and movements, hyoid bone displacement, swallowing muscle area, and pharyngeal residue detection, such as pharyngeal wall mobility. They used convex and linear transducers (3 MHz to 8 MHz) positioned in the submental, laryngeal, and lateral regions of the neck. The subjects were seated and instructed to eat different food volumes and consistencies. The literature mapping showed that ultrasound is a promising diagnostic tool, helping clinicians understand swallowing disorders, as it provides static and dynamic images in different modes and positions. Also, patients receive real-time biofeedback of changes related to dysphagia.

Influence of examiner calibration on clinical and mri diagnosis of temporomandibular joint disc displacement: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to verify the accuracy of clinical protocols for the diagnosis of disc displacement (DD) compared with magnetic resonance imaging (MRI), considering examiners' calibration. METHODS: PubMed, Cochrane (Central), Scopus, Web of Science, LILACS, Embase, Science Direct, Google Scholar, and DANS EASY Archive databases were searched. Two reviewers independently screened and selected the studies. A meta-analysis was conducted using the R Statistical software. Results are shown using sensitivity and specificity, and 95% confidence intervals. RESULTS: Of the 20 studies included in the systematic review, only 3 were classified as low risk of bias. Seventeen studies were included in the meta-analysis. Compared to MRI, clinical protocols showed overall sensitivity and specificity of 0.75 (0.63-0.83) and 0.73 (0.59-0.84) for DD diagnosis, respectively. For DD with reduction, sensitivity was 0.64 (0.48-0.77) and specificity was 0.72 (0.48-0.87). For DD without reduction, sensitivity was 0.58 (0.39-0.74) and specificity 0.93 (0.83-0.97). Only 8 studies reported examiner calibration when performing clinical and/or MRI evaluation; nevertheless, calibration showed a tendency to improve the diagnosis of DD. CONCLUSION: The sensitivity and specificity of clinical protocols in the diagnosis of DD are slightly below the recommended values, as well as the studies lack calibration of clinical and MRI examiners. Examiner calibration seems to improve the diagnosis of DD.

Pancreas units within gastroenterology departments. Organizational and operational standards for a patient-centered service. / Las unidades de páncreas en los servicios de aparato digestivo. Estándares de organización y funcionamiento para un servicio centrado en el paciente.

The Asociación Española de Pancreatología (AESPANC), Asociación Española de Gastroenterología (AEG), and Sociedad Española de Patología Digestiva (SEPD) have developed a consensus document on the standards and recommendations they consider essential for the organization of pancreas units (PUs) within gastroenterology services (GSs) in order to conduct their activities in an efficient, high-quality manner. The consensus document defines PUs and lays down standards relating to their organization, structure, service portfolio, processes, and teaching and research activities. Standards have been categorized as mandatory (requirements to be met to qualify for certification by the scientific societies responsible for the standards) or recommendations. Standards should be updated at most within five years based on the experience gained in Spanish PUs and the advance of knowledge regarding pancreas disease. Development of health outcome indicators, including patient-reported outcome measures (PROMs), is considered a relevant challenge, as is evidence on the association of PU structure and activity standards with health outcomes.

A randomized comparison of two-stage versus traditional one-stage consent for a low-stakes randomized trial.

BACKGROUND/AIMS: It has been proposed that informed consent for randomized trials should be split into two stages, with the purported advantage of decreased information overload and patient anxiety. We compared patient understanding, anxiety and decisional quality between two-stage and traditional one-stage consent. METHODS: We approached patients at an academic cancer center for a low-stakes trial of a mind-body intervention for procedural distress during prostate biopsy. Patients were randomized to hear about the trial by either one- or two-stage consent (n = 66 vs n = 59). Patient-reported outcomes included Quality of Informed Consent (0-100); general and consent-specific anxiety and decisional conflict, burden, and regret. RESULTS: Quality of Informed Consent scores were non-significantly superior for two-stage consent, by 0.9 points (95% confidence interval = -2.3, 4.2, p = 0.6) for objective and 1.1 points (95% CI = -4.8, 7.0, p = 0.7) for subjective understanding. Differences between groups for anxiety and decisional outcomes were similarly small. In a post hoc analysis, consent-related anxiety was lower among two-stage control patients, likely because scores were measured close to the time of biopsy in the two-stage patients receiving the experimental intervention. CONCLUSION: Two-stage consent maintains patient understanding of randomized trials, with some evidence of lowered patient anxiety. Further research is warranted on two-stage consent in higher-stakes settings.

Design and evaluation of a Mobile-Based decision support system to enhance lung transplant candidate assessment and management: knowledge translation integrated with clinical workflow.

BACKGROUND: Accurate and timely decision-making in lung transplantation (LTx) programs is critical. The main objective of this study was to develop a mobile-based evidence-based clinical decision support system (CDSS) to enhance the management of lung transplant candidates. METHOD: An iterative participatory software development process was employed to develop the ImamLTx CDSS. This study was accomplished in three phases. First, required data and standard clinical workflow were identified according to the literature review and expert consensus. Second, a rule-based knowledge-based CDSS application was developed. In the third phase, this CDSS was evaluated. The evaluation was done using the standard Post-Study System Usability Questionnaire (PSSUQ 18.3) and ten usability heuristics factors for user interface design. RESULTS: According to expert consensus, fifty-five data items were identified as essential data sets using the Content Validity Ratio (CVR) formula. By integrating information flow in clinical practices with clinical protocols, more than 450 rules and 500 knowledge statements were extracted. This CDSS provides clinical decision support on an Android platform regarding inclusion and exclusion referral criteria, optimum transplant time based on the type of lung disease, findings of initial assessment, and the overall evaluation of lung transplant candidates. Evaluation results showed high usability ratings due to the fact provided accuracy and sensitivity of this lung transplant CDSS with the information quality domain receiving the highest score (6.305 from 7). CONCLUSION: Through a stepwise approach, the ImamLTx CDSS was developed to provide LTx programs with timely patient data access via a mobile platform. Our results suggest integration with existing workflow to support clinical decision-making and provide patient-specific recommendations.

Validation of guidelines for the care of patients undergoing continuous renal replacement therapy.

BACKGROUND: Continuous renal replacement therapy is one of the most frequently used treatments for acute kidney injury (AKI) in intensive care units (ICUs). It requires professionals with specialized knowledge, specific facilities, and care guidelines to ensure appropriate clinical practice. AIM: To validate the care guidelines for patients undergoing continuous renal replacement therapy. METHOD: This is a methodological study regarding consensual validation of the directives of care. These directives followed the formulation of the research question, a literature review, elaboration of the directive, and validation of the agreement by a committee consisting of seven expert judges. RESULTS: The data were analysed based on the content validity index and described in four categories. Among 40 care-related items, 95% showed a degree of agreement above 80% for adequacy and 82.5% showed a degree of agreement above 75% for relevance. CONCLUSION: The care-related items identified in the literature showed a high percentage of agreement among the judges and reflected the treatment requirements of these patients. RELEVANCE TO CLINICAL PRACTICE: The guideline will be important to assist in the care process regarding patient safety and quality of care.

Shared surgery blood reserve reduces surgery suspension rate due to blood unavailability.

The hemotherapy service in health units with high surgical demand has been pointed out as a challenge, especially concerning storage management simultaneously with transfusion demand attendance. The objective of this study is to analyze service efficacy after the implementation of a new strategy to meet storage and transfusion demands. The present study analyzed the records of the hemotherapy service related to blood components management in surgeries where blood reserve was necessary for RhD positive patients at the National Institute of Traumatology and Orthopedics. A shared compatibility test and surgery reserve from the first semester of 2018 was compared to an equivalent period in 2017, prior to its implementation, under an individualized protocol to each patient scheduled on the surgery map. After the implementation of the shared protocol, the transfusion demand was higher, due to an increase in the percentage of surgeries that required transfusion, as well as to the augmented number of blood components used in the surgeries. Even in the presence of a slight decrease in storage, the hemotherapy assistance was considered efficient, since the percentage of surgery suspension reduced from 2 % to 0.2 % after the implementation of the shared protocol. This improvement resulted in an adjustment in the classification of reasons for surgical procedure cancellations, so that the reason "blood shortage" was repositioned from the first to the seventeenth position. This is the first record of a shared compatibility protocol and surgery reserve and we hope to contribute to the development of the hemotherapy service and surgical patient healthcare.

Adapting obstetric and neonatal services during the COVID-19 pandemic: a scoping review.

BACKGROUND: The provision of care to pregnant persons and neonates must continue through pandemics. To maintain quality of care, while minimizing physical contact during the Severe Acute Respiratory Syndrome-related Coronavirus-2 (SARS-CoV2) pandemic, hospitals and international organizations issued recommendations on maternity and neonatal care delivery and restructuring of clinical and academic services. Early in the pandemic, recommendations relied on expert opinion, and offered a one-size-fits-all set of guidelines. Our aim was to examine these recommendations and provide the rationale and context to guide clinicians, administrators, educators, and researchers, on how to adapt maternity and neonatal services during the pandemic, regardless of jurisdiction. METHOD: Our initial database search used Medical subject headings and free-text search terms related to coronavirus infections, pregnancy and neonatology, and summarized relevant recommendations from international society guidelines. Subsequent targeted searches to December 30, 2020, included relevant publications in general medical and obstetric journals, and updated society recommendations. RESULTS: We identified 846 titles and abstracts, of which 105 English-language publications fulfilled eligibility criteria and were included in our study. A multidisciplinary team representing clinicians from various disciplines, academics, administrators and training program directors critically appraised the literature to collate recommendations by multiple jurisdictions, including a quaternary care Canadian hospital, to provide context and rationale for viable options. INTERPRETATION: There are different schools of thought regarding effective practices in obstetric and neonatal services. Our critical review presents the rationale to effectively modify services, based on the phase of the pandemic, the prevalence of infection in the population, and resource availability.

Validation of a dietary advice protocol for adults with obesity in primary health care according to the Brazilian Dietary Guidelines.

BACKGROUND: Obesity is a non-communicable chronic disease which carries a high cost for the Brazilian Unified Health System. Standardized protocols can help primary health care (PHC) professionals manage the disease. OBJECTIVES: To describe the validation process of a protocol concerning dietary guidelines for adults with obesity in PHC by non-nutrition professionals. METHODS: A validation study of a dietary advice protocol consisting of 6 recommendations was conducted according to Brazilian Dietary Guidelines. The topics incorporated into the recommendations were submitted to a panel of judges for content validity and achieved a Scale Content Validity Index (S-CVI) score >0.80. Subsequently, an online workshop was held and consisted of guiding questions to adequately improve current protocols. Face validity was assessed in a mediation workshop conducted with PHC non-nutrition professionals. Following the validation process, necessary adjustments were made to the eating protocol. RESULTS: The validation process was conducted by a panel of 20 judges and 10 PHC professionals. The content was validated using a 0.98 S-CVI. The online workshop expert panel agreed the instrument provides a trustworthy foundation for appropriate dietary guidelines. Moreover, the judges suggested changes to the flowchart designed to support the professionals' decisions, discussed the absence of quantitative prescription guidelines, and offered additional suggestions to strengthen equity and encourage autonomy in non-nutrition healthcare professionals in PHC. CONCLUSION: This study describes the validation process of a dietary advice protocol for people with obesity, as well as the importance of its integration into PHC.

Obesity is a public health problem that generates high costs for the Brazilian Unified Health System. Dietary guidelines are essential for the care of people suffering from obesity in primary health care (PHC) and should be implemented by all health professionals. However, the absence of protocols based on the Brazilian Dietary Guidelines to support dietary advice constitutes a gap that can prevent the active participation of professionals without training in the field of nutrition. Thus, the objective of this study is to describe the validation process of a protocol for dietary advice for adults with obesity for non-nutrition professionals working in PHC. Researchers and practitioners participated in panels as judges and evaluated the initial text of the protocol, suggesting changes when necessary. Notes on the clarity of the text were also provided. After the requested adjustments, the protocol was validated and made available by the Brazilian Ministry of Health to PHC professionals.

Reproducibility of a protocol for standardized reading of chest X-rays of children household contact of patients with tuberculosis.

BACKGROUND: The interpretation of the chest radiograph may vary because it depends on the reader and due to the non-specificity of findings in tuberculosis (TB). We aim to assess the reproducibility of a standardized chest radiograph reading protocol in contacts of patients with pulmonary TB under the 5 years of age. METHODS: Descriptive, cross-sectional study with children under the age of five, household contacts of patients with confirmed pulmonary TB from Medellín, Bello and Itagüí (Colombia) between Jan-01-2015 and May-31-2016. Standardized reading protocol: two radiologists, blinded independent reading, use of template (Dr. Andronikou design) in case of disagreement a third reading was performed. Kappa coefficient for intra and inter observer agreement, and prevalence ratio were estimated of sociodemographic characteristics, TB exposure and interpretation of chest X-ray. RESULTS: From 278 children, standardized reading found 255 (91.7%) normal X-rays, 10 (3.6%) consistent with TB, and 13 (4.7%) other alterations. Global agreement was 91.3% (Kappa = 0.51). Inter-observer agreement between readers 1-2 was 90.0% (Kappa = 0.59) and 1-3 93.2% (Kappa = 0.59). Intra-observer agreement for reader 1 was 95.5% (Kappa = 0.86), 2 84.0% (Kappa = 0.51), and 3 94.7% (Kappa = 0.68). Greater inter-observer disagreement was between readers 1-2 for soft tissue density suggestive of adenopathy (4.6%), airspace opacification (1.17%) and pleural effusion (0.58%); between readers 1-3 for soft tissue density suggestive of adenopathy (4.2%), opacification of airspace (2.5%) and cavities (0.8%). CONCLUSIONS: Chest radiographs are an affordable tool that contributes to the diagnosis of TB, so having a standardized reading protocol showed good agreement and improves the reproducibility of radiograph interpretation.

Effect of bleaching gel volume on color change and postoperative sensitivity: a randomized clinical study.

OBJECTIVES: Although bleaching therapy is considered a dose-dependent treatment, the effect of the volume of product used is yet to be studied. This study thus aimed to evaluate the influence of bleaching gel volume on chromatic alteration and postoperative sensitivity. METHODOLOGY: Thirty patients were selected and allocated into three groups; the lower canines were analyzed according to the volume of gel used: GI-0.025 mL, GII-0.05 mL, and GIII-0.10 mL. Chromatic alteration analysis was performed using a portable digital spectrophotometer by calculating the ΔE, ΔE00, ΔL*, Δa*, and Δb* values and the whiteness index (WID). Spontaneous sensitivity was assessed using a questionnaire, and sensitivity was stimulated by thermo-sensory analysis. Analyses were conducted in five stages: baseline, after 1st, 2nd, and 3rd bleaching sessions, and 14 days after the end. Data were analyzed using the two-way ANOVA test with repeated measures and Tukey's post hoc test (p < 0.05). RESULTS: It was observed that ΔE, ΔE00, and ΔL* were similar between groups at the end of the bleaching therapy; and the values of Δa*, Δb*, and WID were higher in the GIII group. For sensitivity, it was found that the GI was the one with the lowest values; o GII intermediate values; while the GIII group presents the highest values of spontaneous and stimulated sensitivity. CONCLUSION: Gel volume influenced the response to bleaching and significantly influenced the spontaneous sensitivity and cold stimulus. CLINICAL RELEVANCE: The amount of bleaching gel used during therapy is key to both the response to color change and postoperative sensitivity.

Improving cardiovascular health in primary care in Saint Lucia through the HEARTS Initiative.

Objective: To improve blood pressure control and hypertension registry coverage at six demonstration sites in St Lucia. Methods: From January 2020 to December 2021, St Lucia's Ministry of Health, with support of the Pan American Health Organization, implemented the HEARTS Technical Package in six primary health care facilities with six-monthly monitoring of blood pressure control and hypertension registry coverage. The modules included healthy-lifestyle counselling, evidence-based treatment protocols, access to essential medicines and technology, risk-based cardiovascular management, team-based care and systems for monitoring. Results: Levels of blood pressure control at 6, 12, 18 and 24-months after the intervention were 37.1%, 28.9%, 33.9% and 36.5% respectively. Hypertension registry coverage increased by 17.8% (1 434 to 1 689) for patients accessing service. Implementing the monitoring for action initiative 12 to 15 months after the start of the intervention resulted in policy and operational changes, improved documentation, and provided accurate and reliable data. Conclusions: The HEARTS initiative unearthed basic infrastructural challenges in blood pressure control. The essential elements for success were (1) buy in at all levels of the health sector; (2) addressing policy and operational changes; (3) accurate documentation and required analysis; (4) standardization of equipment and procedures and (5) regular monitoring and evaluation. Capacity building underpinned all changes.

Chile's public healthcare sector hypertension control rates before and during the pandemic and HEARTS implementation.

Hypertension (arterial blood pressure ≥ 140/90 mmHg) is a risk factor for cardiovascular diseases, with the greatest burden of attributable deaths in Chile, having a national prevalence of 27.6%. In 2018, the implementation of HEARTS begun in primary health care centers of the Public Health System, with the aim of achieving increase in control rates, by raising the proportion of hypertensive individuals who meet blood pressure goals (< 140/90 mmHg for individuals 15-79 years old and of 150/90 mmHg for individuals 80 years and older), and thus contributing to reduce cardiovascular morbidity and mortality associated with this condition. This is a descriptive study that follows average treatment and control rates from the Public Health System between 2017-2021 obtained from health centers statistics reports during HEARTS implementation. Treatment and control rates remained at 57% and 39% respectively between 2017-2019. Between 2020 and 2021, in the context of the SARS-CoV-2 pandemic, treatment and control rates decreased very significantly, reaching 46% and 26%, respectively, in December 2021, even though the number of centers reporting the implementation of HEARTS increased from 227 to 387 in this same period. Prior to the pandemic, during the last quarter of 2019, a decrease in cardiovascular health controls was already observed as a result of social protests. In light of the results, the technical pillars of the HEARTS Initiative have an important role in helping to recover the population control rates reached in 2019 and increasing the speed to achieve better hypertension control rates.

La hipertensión arterial (presión arterial ≥ 140/90 mmHg) es un factor de riesgo para las enfermedades cardiovasculares, que tienen la mayor carga de muertes atribuibles en Chile. En este país, la hipertensión tiene una prevalencia nacional del 27,6%. En el 2018 se inició la aplicación del paquete técnico HEARTS en los centros de atención primaria de salud del sistema público de salud de Chile, con el objetivo de lograr un aumento de las tasas de control, al elevar la proporción de personas hipertensas que cumplen con las metas de presión arterial (< 140/90 mmHg para personas de 15 a 79 años y de 150/90 mmHg para personas de 80 años o más) y así contribuir a reducir la morbilidad y la mortalidad cardiovascular asociadas a esta enfermedad. En este estudio descriptivo se realiza un seguimiento de las tasas promedio de tratamiento y control del sistema público de salud entre el 2017 y el 2021 obtenidas de los informes estadísticos de los centros de salud durante la aplicación de la iniciativa HEARTS. Las tasas de tratamiento y control se mantuvieron en 57% y 39%, respectivamente, en el período entre el 2017 y el 2019. Entre el 2020 y el 2021, en el contexto de la pandemia de SARS-CoV-2, las tasas de tratamiento y control disminuyeron de manera muy significativa, y se ubicaron en 46% y 26%, respectivamente, en diciembre del 2021, a pesar de que el número de centros que notificaron la aplicación de HEARTS aumentó de 227 a 387 en el mismo período. Antes de la pandemia, en el último trimestre del 2019, ya se había observado una disminución en los controles de salud cardiovascular debido a las protestas sociales. En vista de estos resultados, los pilares técnicos de la iniciativa HEARTS desempeñan un papel importante para ayudar a recuperar las tasas de control que se habían alcanzado en el 2019 y acelerar la consecución de mejores tasas de control de la hipertensión.

A hipertensão (pressão arterial ≥ 140/90 mmHg) é um fator de risco para doenças cardiovasculares, com a maior carga de mortes atribuíveis no Chile, onde a prevalência nacional é de 27,6%. Em 2018, teve início a implementação da iniciativa HEARTS em centros de atenção primária à saúde do sistema de saúde pública, com o objetivo de elevar as taxas de controle, pelo aumento da proporção de indivíduos hipertensos que alcançam as metas de pressão arterial (< 140/90 mmHg para pessoas de 15-79 anos e de 150/90 mmHg para pessoas a partir de 80 anos), e, assim, contribuir para a redução da morbimortalidade cardiovascular associada a essa condição. Este é um estudo descritivo que acompanha as taxas médias de tratamento e controle no sistema de saúde pública entre 2017 e 2021, obtidas de relatórios estatísticos dos centros de saúde durante a implementação da iniciativa HEARTS. Entre 2017 e 2019, as taxas de tratamento e de controle foram, respectivamente, de 57% e 39%. Entre 2020 e 2021, no contexto da pandemia causada pelo SARS-CoV-2, houve uma diminuição muito significativa das taxas de tratamento e de controle, que chegaram, respectivamente, a 46% e 26% em dezembro de 2021, embora o número de centros que informaram ter implementado o pacote HEARTS tenha aumentado de 227 para 387 no mesmo período. Antes da pandemia, durante o último trimestre de 2019, já se observava uma diminuição dos controles da saúde cardiovascular em consequência de uma onda de protestos sociais. Os resultados mostram que os pilares técnicos da iniciativa HEARTS são importantes para ajudar a recuperar as taxas de controle na população alcançadas em 2019 e aumentar a velocidade para atingir melhores taxas de controle da hipertensão.
