Barriers and facilitators to implementing a multilevel, multicomponent intervention promoting colorectal cancer screening in health centers: a qualitative study of key informant perspectives

BACKGROUND

Colorectal cancer (CRC) continues to be a major cause of death in the U.S. despite the availability of effective screening tools. U.S. Latinos have lower rates of CRC screening and higher rates of death due to colorectal disease compared to non-Hispanic whites. Federally Qualified Health Centers (FQHCs) serve medically underserved populations, including many Latino patients. Given the low CRC screening rates, identifying culturally sensitive and cost-effective methods of promoting screening is a priority for many FQHCs.

METHODS

We interviewed FQHC leaders and providers using the Consolidated Framework for Implementation Research (CFIR) to identify barriers and facilitators to implementation of a multilevel, multicomponent (ML-MC) CRC screening intervention (i.e., promotor navigation and group-based education) in FQHCs. A rapid qualitative analysis approach was used to identify themes organized according to the following CFIR constructs: intervention characteristics, outer and inner settings, and characteristics of the individual.

RESULTS

We completed interviews with 13 healthcare professionals in leadership positions at six FQHCs. The participating FQHCs perceived the ML-MC screening CRC program as feasible and expressed interest in implementing the program at their sites. Facilitators included financial incentives for increasing screening rates, the need for patient education programming, and involving promotores to support the work of clinical teams. Barriers included concerns about available resources to implement new programs, lack of federal reimbursement for health education, competing priorities of other health concerns, and the need for more resources for confirmatory screening and treatment following a positive screen.

CONCLUSIONS

FQHCs provide essential primary care to millions of underserved patients in the U.S. and have the ability and motivation to provide screenings for colorectal cancer. Partnering with an academic institution to deliver a group-based, promotor-led CRC screening intervention for patients not up to date with screening could help increase screening rates. By identifying the specific barriers and facilitators to implementing CRC intervention, findings suggest that group-based, promotor-led interventions are a promising approach.

EAACI/ENDA position paper on drug provocation testing

In drug hypersensitivity, drug provocation testing (DPT), also called drug challenge, is the gold standard for investigation. In recent years, risk stratification has become an important tool for adjusting the diagnostic strategy to the perceived risk, whilst still maintaining a high level of safety for the patient. Skin tests are recommended before DPT but may be omitted in low-risk patients. The task force suggests a strict definition of such low-risk patients in children and adults. Based on experience and evidence from studies of allergy to beta-lactam antibiotics, an algorithm on how to adjust DPT to the risk, and when to omit skin tests before DPT, is presented. For other antibiotics, non-steroidal anti-inflammatory drugs and other drugs, skin tests are poorly validated and DPT is frequently necessary. We recommend performing DPT with chemotherapeutics and biologicals to avoid unnecessary desensitization procedures and DPT with skin tests negative contrast media. We suggest DPT with anesthetics only in highly specialized centers. Specifics of DPT to proton pump inhibitors, anticonvulsants and corticosteroids are discussed. This position paper provides general recommendations and guidance on optimizing use of DPT, whilst balancing benefits with patient safety and optimizing the use of the limited available resources.

Characteristics Associated with Sudden Unexpected Infant Death in a Rural Hispanic Population: A Case-Control Study

INTRODUCTION

Sudden unexpected infant death (SUID) is the leading cause of death among U.S. infants aged 28 days to 1 year. In Kansas, Hispanic infant mortality is nearly 50% higher than non-Hispanic White. Further, the SUID rate did not change between 2005-2018, while rates for non-Hispanic Black and White infants decreased significantly. This study sought to identify characteristics and behaviors of Hispanic birthing persons related to SUID.

METHODS

Linked Kansas birth/death vital statistics data (2005-2018) identified Hispanic birthing persons with a singleton birth who experienced SUID. To reduce confounding effects, greedy nearest neighbor matching paired each SUID case sequentially with the four nearest controls based on age, race, payor source and parity. Matching procedures, likelihood-ratio χ2, Fisher exact test and multiple logistic regression model with Firth's penalized maximum likelihood estimation were computed.

RESULTS

Of 86,052 Hispanic singleton births, 66 involved SUID and were matched with 264 controls. No differences were related to marital status, population density of residence, education level, language spoken, prenatal BMI, weight gained during pregnancy, adequacy of prenatal care, enrollment in WIC, or state immunization registry participation (all p>0.05). However, tobacco use during pregnancy contributed to a three times greater risk of SUID (OR=3.208; 95% CI=1.438 to 7.154). Multivariable models for behavioral variables revealed low predictive accuracy with area under the ROC curve=0.6303.

CONCLUSION

This study suggests SUID deaths to rural Hispanic families are likely multifaceted. Study results inform educational programs on the importance of addressing tobacco cessation in SUID risk reduction interventions for Hispanic families.

Post-acute phase and sequelae management of epidermal necrolysis: an international, multidisciplinary DELPHI-based consensus

BACKGROUND

Long-term sequelae are frequent and often disabling after epidermal necrolysis (Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)). However, consensus on the modalities of management of these sequelae is lacking.

OBJECTIVES

We conducted an international multicentric DELPHI exercise to establish a multidisciplinary expert consensus to standardize recommendations regarding management of SJS/TEN sequelae.

METHODS

Participants were sent a survey via the online tool "Survey Monkey" consisting of 54 statements organized into 8 topics: general recommendations, professionals involved, skin, oral mucosa and teeth, eyes, genital area, mental health, and allergy workup. Participants evaluated the level of appropriateness of each statement on a scale of 1 (extremely inappropriate) to 9 (extremely appropriate). Results were analyzed according to the RAND/UCLA Appropriateness Method.

RESULTS

Fifty-two healthcare professionals participated. After the first round, a consensus was obtained for 100% of 54 initially proposed statements (disagreement index < 1). Among them, 50 statements were agreed upon as 'appropriate'; four statements were considered 'uncertain', and ultimately finally discarded.

CONCLUSIONS

Our DELPHI-based expert consensus should help guide physicians in conducting a prolonged multidisciplinary follow-up of sequelae in SJS-TEN.

Marine debris and associated organic pollutants in surface waters of Chiloé in the Northern Chilean Patagonia (42°-44°S)

We report the occurrence of plastics and associated persistent organic pollutants (POPs) in surface waters from Northern Chilean Patagonia. A total of 200 particles were found during the conducted survey. The highest number of particles found was 0.6 item m^-3. We found that 53 % of the collected particles corresponded to plastic, with an average of 0.19 ± 0.18 item m^-3. Microplastics (68 %) were the dominant size found in the area, followed by macroplastics (18 %) and mesoplastics (14 %). Most plastic particles were white (55 %) while others were <10 % each. Black and light blue represented 9 %; red, dark blue, and other colors 7 %; and green 6 %. Fragments were the most frequent shape of plastic debris (38 %), followed by Styrofoam (30 %) and fiber (27 %). Higher PBDE levels were found in the central zone, and those were higher than DDT, PeCB, HCB, and PCB levels. This study is the first report on POP occurrence in marine plastic debris from Chiloé Sea in the Northern Chilean Patagonia.

To know and be known: Mexican borderland mothers’ epistemic experiences

Few studies have examined how Mexican-origin mothers experience epistemic harm irrespective of its impact on childrearing. Clinicians and researchers can benefit from understanding how public narratives of (un)belonging influence the development of Mexican-origin mothers’ knowledge construction and identity as knowers. We used Chicana decolonial feminisms to examine the epistemic experiences of seven Mexican-origin mothers in the US–Mexico borderlands during a period of heightened racist, nativist, and anti-family violence. Participants between the ages of 22 and 51 years completed in-depth semi structured testimonio interviews in Spanish, English, and Spanglish, an admixture of both English and Spanish common among bilingual Americans of Mexican descent. Epistemic experiences were intertwined with crossing, bridging, and the liminality associated with navigating diverse citizenship discourses as gendered, racialized knowers. Three themes were identified including brown-on-brown conflict, discrimination denial, and co-family as sources of new knowledge. Participants experienced epistemic harm from expected and unexpected sources, including within-family invalidations that were especially disorienting. Epistemic growth arose from relational, integrated co-construction of new knowledge, but epistemic harm also appeared to cultivate internalized nativist fears in some participants.

Integrated health and social care evaluation framework for mental health and drug addiction care

Background

Guiding the decision-making process in mental health investments is advisable. The objective of the study is to develop a framework for evaluating the quality of integrated health and social care in Mental Health and Drug Addiction (MH&DA)

Methods

A literature review helped to establish a definition of integrated care specific to MH&DA and to identify potential indicators for its evaluation. The quality of integrated care was assessed through focus groups (FGs) and interviews (INs) with three different profiles: professionals (2FGs & 2 INs), patients (3 FGs & 2 INs) and families/carers (2FGs & 2 INs). Additional indicators were also obtained from them.

Results

Out of 2,226 publications identified, 87 (4%) were reviewed in full. According to the literature, integrated care in MH&DA is based on four main components: case management, comprehensive assessment, individualised care plan and care coordination among different providers. Based on these components, an operational definition of integrated care was developed and validated in the FGs and INs. Positive aspects identified were a respectful approach and positive experiences of coordination between social and community network. Regarding indicators about 400 were identified, after screening were reduced to 60: 25% corresponded to accessibility, 20% person-centred care, 16% each to care coordination and to effectiveness. In general, the main threats to the quality of care, identified in FGs and INs, matched the dimensions with the highest proportion of indicators (i.e., limited care resources, poor coordination and communication among professionals and services, and barriers in accessing specialized treatment).

Conclusions

According to literature, integrated care in MH&DA seems to be mainly evaluated in terms of accessibility and person-centred care. In a following phase, a large group of experts will be key to select the most relevant dimensions and indicators for the evaluation in a Delphi study.

Key messages

Combined cardiopulmonary test and exercise Doppler echocardiography in systemic sclerosis

Background

Cardiopulmonary exercise test (CPET) and exercise Doppler echocardiography (EDE) may be useful for the early detection of pulmonary hypertension in systemic sclerosis (SSc)

Aim

To assess the feasibility of CPET and EDE in detecting early changes in gas exchange and/or pulmonary hemodynamics in SSc

Methods

From 2016 to 2021, we evaluated 19 SSc patients (Group 1, age = 52.58±11.27, women 17 (89.5%)), and age 32.10±6.67, men 17 (89.4%) matched healthy controls (Group 2). Simultaneous CPET and EDE were performed. With CPET, we assessed peak oxygen uptake (VO2), peak respiratory quotient (RQ), respiratory equivalent ratio for carbonic gas (VE/VCO2), and maximal respiratory equivalent divided by maximal ventilatory ventilation (V̇E Max/VVM). With EDE, we assessed tricuspid regurgitant velocity (TRV) jet and pulmonary flow acceleration time (ACT) to derive systolic pulmonary arterial pressure (SPAP).

Results

Exercise duration was similar in the 2 groups (Group 1 = 9.2±2.93 vs Group 2 = 10.14±1.78 minutes). Among CPET parameters, SSc patients showed lower peak VO2 (Group 1 = 1.23±0.55 vs Group 2 = 2.45±0.7, p&lt;0.001), similar RQ (1.10±0.10 vs 1.17±0.09;. p=0.036), VE/VCO2 (Group 1 = 31.90±3.65 vs Group 2 = 23.79±2.64, p&lt;0.001) and V̇E Max/VVM (Group 1 = 1.93±0.60 vs Group 2 = 1.76±0.36, p=NS). With EDE, feasibility at peak stress was low for TRV (Group 1 = 42% vs Group 2 = 58%, p=NS), moderate for ACT (Group 1 = 53% vs Group 2 = 78%, p=NS) and high when at least one was technically adequate (Group 1 = 73% vs Group 2 = 100%, p&lt;0.001). Rest TRV (Group 1 = 2.48±0.14 vs Group 2 = 2.08±0.12 m/s, p=0.033) and ACT (Group 1 = 100.14±10.63 vs Group 2 = 108.86±6.38 ms, p=0.482) showed similar values in the 2 groups (será que ficou similar?). During stress, TRV increased more markedly in SSc (Group 1 = 3.33±0.32 vs Group 2 = 2.34±0.09 m/s, p=0.004) and ACT decreased (Group 1 = 81.9±6.54 vs 73.39±5.18 ms, p=0.304), with estimated peak SPAP higher in SSc (Group 1 = 53.34±7.88 vs Group 2 = 43.33±5.49, p&lt;0.001): see figure.

Conclusion

CPET and EDE offer complementary information on gas exchange and pulmonary hemodynamics in SSc and can detect early alterations missed by resting assessment. The success rate of EDE increases significantly with the combination of TRV and ACT.

SARS-CoV-2 Brain Regional Detection, Histopathology, Gene Expression, and Immunomodulatory Changes in Decedents with COVID-19

Brains of 42 COVID-19 decedents and 107 non-COVID-19 controls were studied. RT-PCR screening of 16 regions from 20 COVID-19 autopsies found SARS-CoV-2 E gene viral sequences in 7 regions (2.5% of 320 samples), concentrated in 4/20 subjects (20%). Additional screening of olfactory bulb (OB), amygdala (AMY) and entorhinal area for E, N1, N2, RNA-dependent RNA polymerase, and S gene sequences detected one or more of these in OB in 8/21 subjects (38%). It is uncertain whether these RNA sequences represent viable virus. Significant histopathology was limited to 2/42 cases (4.8%), one with a large acute cerebral infarct and one with hemorrhagic encephalitis. Case-control RNAseq in OB and AMY found more than 5000 and 700 differentially expressed genes, respectively, unrelated to RT-PCR results; these involved immune response, neuronal constituents, and olfactory/taste receptor genes. Olfactory marker protein-1 reduction indicated COVID-19-related loss of OB olfactory mucosa afferents. Iba-1-immunoreactive microglia had reduced area fractions in cerebellar cortex and AMY, and cytokine arrays showed generalized downregulation in AMY and upregulation in blood serum in COVID-19 cases. Although OB is a major brain portal for SARS-CoV-2, COVID-19 brain changes are more likely due to blood-borne immune mediators and trans-synaptic gene expression changes arising from OB deafferentation.

Prediction of Treatment Response in Patients with Major Depressive Disorder: A Meta-Analysis of Functional Magnetic Resonance Imaging Studies

Introduction

Identifying the optimal treatment for individuals with major depressive disorder (MDD) is often a long and complicated process. Functional magnetic resonance imaging (fMRI) studies have been used to help predict and explain differences in treatment response among individuals with MDD.

Objectives

We conducted a comprehensive meta-analysis of treatment prediction studies utilizing fMRI in patients with MDD to provide evidence that neural activity can be used to predict response to antidepressant treatment.

Methods

A multi-level kernel density analysis was applied to these primary fMRI studies, in which we analyzed brain activation patterns of depressed patients (N= 364) before receiving antidepressant treatment.

Results

The results of this analysis demonstrated that hyperactivity in six brain regions significantly predicted treatment response in patients with MDD: the right anterior cingulate, right cuneus, left fusiform gyrus, left middle frontal gyrus, right cingulate gyrus, and left superior frontal gyrus.

Conclusions

This study provides evidence that neural activity, as measured by standard fMRI paradigms, can be used to successfully predict response to antidepressant treatment. This may be used in the future clinically to improve decision-making processes and treatment outcomes for patients.

Liver transplant with controlled donors after circulatory death with normothermic regional perfusion and brain dead donors: A multicenter cohort study of transfusion, one-year graft survival and mortality

BACKGROUND

Controlled donation after circulatory death (cDCD) has expanded the donor pool for liver transplantation (LT). However, transfusion requirements and perioperative outcomes should be elucidated. The aim of this multicenter study was to assess red blood cell (RBC) transfusions, one-year graft and patient survival after LT after cDCD with normothermic regional perfusion (NRP) compared with donors after brain death (DBD).

METHODS

591 LT carried out in ten centers during 2019 were reviewed. Thromboelastometry was used to manage coagulation and blood product transfusion in all centers. Normothermic regional perfusion was the standard technique for organ recovery.

RESULTS

447 patients received DBD and 144 cDCD with NRP. Baseline MCF Extem was lower in the cDCD group There were no differences in the percentage of patients (63% vs. 61% p = 0.69), nor in the number of RBC units transfused (4.7 (0.2) vs 5.5 (0.4) in DBD vs cDCD, p = 0.11. Twenty-six patients (6%) died during admission for LT in the DBD group compared with 3 patients (2%) in the cDCD group (p = 0.15). To overcome the bias due to a worse coagulation profile in cDCD recipients, matched samples were compared. No differences in baseline laboratory data, or in intraoperative use of RBC or one-year outcome data were observed between DBD and cDCD recipients.

CONCLUSIONS

cDCD with NRP is not associated with increased RBC transfusion. No differences in graft and patient survival between cDCD and DBD were found. Donors after controlled circulatory death with NRP can increasingly be utilized with safety, improving the imbalance between organ donors and the ever-growing demand.

Promoting Safe Sleep, Tobacco Cessation, and Breastfeeding to Rural Women During the COVID-19 Pandemic: Quasi-Experimental Study

BACKGROUND

Safe Sleep Community Baby Showers address strategies to prevent sleep-related infant deaths. Due to the COVID-19 pandemic, these events transitioned from in-person to virtual.

OBJECTIVE

This study describes outcomes of transitioning Safe Sleep Community Baby Showers to a virtual format and compares outcomes to previous in-person events.

METHODS

Participants from four rural Kansas counties were emailed the presurvey, provided educational materials (videos, livestream, or digital documents), and completed a postsurvey. Those who completed both surveys received a portable crib and wearable blanket. Within-group comparisons were assessed between pre- and postsurveys; between-group comparisons (virtual vs in-person) were assessed by postsurveys.

RESULTS

Based on data from 145 in-person and 74 virtual participants, virtual participants were more likely to be married (P<.001) and have private insurance (P<.001), and were less likely to report tobacco use (P<.001). Both event formats significantly increased knowledge and intentions regarding safe sleep and avoidance of secondhand smoke (all P≤.001). Breastfeeding intentions did not change. Differences were observed between in-person and virtual meetings regarding confidence in the ability to avoid secondhand smoke (in-person: 121/144, 84% vs virtual: 53/74, 72%; P=.03), intention to breastfeed ≥6 months (in-person: 79/128, 62% vs virtual: 52/66, 79%; P=.008), and confidence in the ability to breastfeed ≥6 months (in-person: 58/123, 47% vs virtual: 44/69, 64%; P=.02).

CONCLUSIONS

Although both event formats demonstrated increased knowledge/intentions to follow safe sleep recommendations, virtual events may further marginalize groups who are at high risk for poor birth outcomes. Strategies to increase technology access, recruit priority populations, and ensure disparities are not exacerbated will be critical for the implementation of future virtual events.

Quantifying the burden of premature mortality at national level in France in 2016

Background

Efforts to accurately measure premature mortality are important to monitor the impact of diseases and injuries on population health and to set policy priorities. This is an ongoing study with a strong collaboration between Santé Publique France and the French National Health Insurance, whose main objective is to provide the first national estimates of Years of Life Lost (YLLs) for all causes of death in France.

Methods

The French national health data system (SNDS) contains detailed nationwide causes of death data, reported using ICD-10 codes. We used the underlying cause, as defined by the Center for Epidemiology on Medical Causes of deaths, of all deaths for year 2016 (the last year available). For this preliminary study without redistribution of ill-defined deaths (IDDs), national sex-specific life expectancy tables were used to estimate YLLs by age class, sex, and cause of death categories at national level. We identified and quantified IDDs and also compared YLLs to crude mortality.

Results

In 2016, we estimated approximately 7.3 million YLLs (586,519 registered deaths), of which 35.1% were due to neoplasms, 17.8% to cardiovascular diseases (respectively 34.5% and 17.3% in men; 35.8% and 18.4% in women) and 10.3% to injuries (4.9% among people aged 65 or more at time of death; 34.5% among people aged 25-44). Approximately 27% of the deaths registered were IDDs, representing approximately 1.8 million YLLs.

Conclusions

These preliminary results confirm the importance of YLLs as a metric to target preventive strategies according to age. Moreover, by quantifying IDDs, we highlight that data gaps are important even in settings with highly developed health information systems. Next steps include applying an IDD redistribution methodology, aspirational life table and computing subnational YLLs. The French collaborative initiative should address those gaps and propose national and subnational burden metrics in the following months.

Key messages

Methodological and data requirements to compute YLLs constitute a challenge even in settings with developed health information systems, highlighting the need of national institutional collaborations. Highlight data gaps in terms of ill-defined deaths in mortality database.

Blunted heart rate reserve with dobutamine stress echocardiography predicts outcome in diabetes and/or chronic kidney disease

Background

A blunted heart rate reserve (HRR) during dobutamine stress echo (DSE) is an index of the altered cardiac sympathetic reserve, which is frequently present in diabetes mellitus (DM) or chronic kidney disease (CKD).

Aim

To assess the prognostic value of HRR during DSE.

Methods

We recruited 280 patients (mean age 62.9±13.1 years; 128 (45.7%) male; 28.2% on beta-blockers at the time of testing) who underwent DSE for known or suspected coronary artery disease and/or heart failure and were followed-up. Four subsets were identified: Group 1 (111 pts without DM or CKD); group 2 (37 with DM without CKD); group 3 (90 with CKD with or without DM); and group 4 (42 with CKD on dialysis). HRR was calculated by EKG as the peak/rest HR ratio.

Results

Ischemia was identified in 34/280 (12.1%) pts. During a median follow-up time of 40.3±30.5 months, 120 events occurred: 46 deaths, 15 non-fatal myocardial infarctions, 23 hospital admissions for acute decompensated heart failure, and 36 myocardial revascularizations. Multivariable comparison of HRR among the 4 groups using post hoc test showed a blunted HRR in group 3 (1.66±0.32) and 4 (1.65±0.27) when compared with group 1 (HRR 1.85±0.35), p&lt;0.01. Group 2 (1.73±0.28) was not different from any group (p=ns). Groups 3 and 4 were not different between them (p=ns). A post hoc Tukey test for HRR separated in tercils, 1st: HRR &lt;1.59, 2nd: 1.59 &lt; HRR &lt;1.86 and 3rd: HRR &gt;1.86 (p&lt;0.000). Kaplan-Meier curves showed blunted HRR as an independent predictor of event-free survival in the overall group - 1st: 66.08±5.9 months, 95% CI 54.3–77.7; 2nd: 69.52±6.5, 95% CI 56.6–82.3; 3rd: 90.05±5.3, 95% CI 79.5–100.5. See Figure. HRR was comparable in patients with and without inducible ischemia and off or on beta-blockers.

Conclusion

A blunted HRR during DSE is frequent in patients with DM and CKD, independent of inducible ischemia and use of beta-blockers, and is a useful non-imaging predictor of adverse events.

Safe sleep community baby showers to reduce infant mortality risk factors for women who speak Spanish

OBJECTIVES

In the United States, sleep-related deaths are one of the primary causes of death for infants age 28 days to one year. The American Academy of Pediatrics (AAP) developed Safe Sleep Recommendations which provide risk reduction strategies for sleep-related infant deaths. Interventions such as Safe Sleep Community Baby Showers have increased knowledge and intentions to engage in these safe sleep behaviors for women who speak English. This study assessed the feasibility, acceptability and initial outcomes of Safe Sleep Community Baby Showers for women who speak Spanish.

METHODS

Six Spanish Safe Sleep Community Baby Showers were held in Sedgwick County, Kansas. One hundred forty-six pregnant or recently delivered women who spoke Spanish completed pre- and post-assessments. Univariate comparisons were made using McNemar's test for paired dichotomous variables.

RESULTS

Participants had a high school diploma/General Educational Diploma (GED) or less (75.3%), and were uninsured (52.1%) or had Medicaid (n = 49; 33.6%). The majority reported being very satisfied (n = 130; 89.0%) or satisfied (n = 8; 5.5%). Compared to baseline, significant increases in intentions and confidence to follow the AAP Safe Sleep Recommendations were observed following the events. The majority of participants reported intending to place their infant on the back to sleep (98.6%), use only a safe surface (crib, portable crib, bassinet; 99.3%), and only include safe items (firm mattress, fitted sheet; 93.5%) (all p < .001).

CONCLUSIONS

Study findings support both feasibility and acceptability of modifying Safe Sleep Community Baby Showers to provide culturally and linguistically appropriate education for women who speak Spanish. Initial outcomes suggest increased intentions to follow safe sleep recommendations.

Experience with the use of siltuximab in patients with SARS-CoV-2 infection

OBJECTIVE

The study aims to describe characteristics and clinical outcome of patients with SARS-CoV-2 infection that received siltuximab according to a protocol that aimed to early block the activity of IL-6 to avoid the progression of the inflammatory flare.

METHODS

Retrospective review of the first 31 patients with SARS-CoV-2 treated with siltuximab, in Hospital Clinic of Barcelona or Hospital Universitario Salamanca, from March to April 2020 with positive polymerase-chain reaction (PCR) from a nasopharyngeal swab.

RESULTS

The cohort included 31 cases that received siltuximab with a median (IQR) age of 62 (56-71) and 71% were males. The most frequent comorbidity was hypertension (48%). The median dose of siltuximab was 800 mg ranging between 785 and 900 mg. 7 patients received siltuximab as a salvage therapy after one dose of tocilizumab. At the end of the study, a total of 26 (83.9) patients had been discharged alive and the mortality rate was 16.1% but only 1 out of 24 that received siltuximab as a first line option (4%).

CONCLUSIONS

Siltuximab is a well-tolerated alternative to tocilizumab when administered as a first line option in patients with COVID-19 pneumonia within the first 10 days from symptoms onset and high C-reactive protein.

Frequency of outpatient care adverse events in an occupational mutual insurance company in Spain

BACKGROUND

Occupational mutual insurance companies (OMICs), in collaboration with the Spanish Social Security System, provide healthcare and manage the economic benefits for the workers in Spain. They have ambulatory care centers that attend outpatient trauma pathology, although most of the studies published have focused on surgical and hospital activity. The aim of this study was to detect adverse events (AEs) in outpatient trauma care in the context of an OMIC.

METHODS

A cohort study designed to identify harmful safety incidents (adverse events, AEs) in 2017 was conducted. A random sample of 313 medical records among patients who were visited more than 3 medical and nursing attendances during their outpatient process. The AEs detected were classified according to category, severity and preventability.

RESULTS

We identified 48 AEs (15.3% of medical records, 95% CI 11.3-19.3), most of them procedure-related, while 27 (56.2%) were preventable and 46 mild (95.8%).

CONCLUSIONS

The AEs identified are double than those found in primary care general consultations in Spain and are close to the lower range of studies on surgical AEs in traumatology and orthopedics. Preventable AEs were within expected limits. Over half of AEs are preventable, within that group, the mild AEs have an increased rate of preventability. These results highlight the relevance of research of patient safety in the outpatient care of trauma and orthopaedic procedures in an OMIC for patient safety and contribute to introduce improvements in outpatient care.

Tuberculosis infection in HIV vs. non-HIV patients

OBJECTIVES

Tuberculosis (TB) is the most common opportunistic infection and cause of mortality among people living with HIV, and it is possible that it may also influence the evolution of the HIV infection. We assessed the differences between HIV-positive and -negative people infected with TB.

METHODS

The present study is a cross-sectional retrospective study by electronic record revision. We included patients admitted to a tertiary hospital with a diagnosis of TB between 2011 and 2016, comparing those with HIV coinfection with non-HIV patients, according to demographic and clinical characteristics.

RESULTS

This study included 591 patients, of whom 32% were HIV-coinfected. HIV-TB patients were younger, with a predominance of male gender. Considering TB risk factors, there was a higher prevalence of homelessness and intravenous drug use in the HIV group. In the non-HIV group, direct contact with other patients with TB and immunosuppression were more prevalent. Relative to TB characteristics, the HIV-coinfected group presents with a higher prevalence of disseminated disease and a higher occurrence of previous TB infection. Cancer was the most frequent cause of immunosuppression in the HIV group and the number testing positive for TB via microbiological culture was lower. Assessment of microbiological resistance and in-hospital mortality showed similar numbers in both groups.

CONCLUSIONS

There are few papers comparing clinical course of TB between HIV-infected and non-infected patients. Our study differs from others in the literature as we focused on a country with middling incidence of TB and further characterized the differences between HIV-infected and non-infected patients which can contribute to the management of these patients.

Tocilizumab reduces the risk of ICU admission and mortality in patients with SARS-CoV-2 infection

Objectives

In some patients the immune response triggered by SARS-CoV-2 is unbalanced, presenting an acute respiratory distress syndrome which in many cases requires intensive care unit (ICU) admission. The limitation of ICU beds has been one of the major burdens in the management around the world; therefore, clinical strategies to avoid ICU admission are needed. We aimed to describe the influence of tocilizumab on the need of transfer to ICU or death in non-critically ill patients.

Material and methods

A retrospective study of 171 patients with SARS-CoV-2 infection that did not qualify as requiring transfer to ICU during the first 24h after admission to a conventional ward, were included. The criteria to receive tocilizumab was radiological impairment, oxygen demand or an increasing of inflammatory parameters, however, the ultimate decision was left to the attending physician judgement. The primary outcome was the need of ICU admission or death whichever came first.

Results

A total of 77 patients received tocilizumab and 94 did not. The tocilizumab group had less ICU admissions (10.3% vs. 27.6%, P=0.005) and need of invasive ventilation (0 vs 13.8%, P=0.001). In the multivariable analysis, tocilizumab remained as a protective variable (OR: 0.03, CI 95%: 0.007-0.1, P=0.0001) of ICU admission or death.

Conclusions

Tocilizumab in early stages of the inflammatory flare could reduce an important number of ICU admissions and mechanical ventilation. The mortality rate of 10.3% among patients receiving tocilizumab appears to be lower than other reports. This is a non-randomized study and the results should be interpreted with caution.

Management of anaphylaxis due to COVID-19 vaccines in the elderly

Older adults, especially men and/or those with diabetes, hypertension, and/or obesity, are prone to severe COVID‐19. In some countries, older adults, particularly those residing in nursing homes, have been prioritized to receive COVID‐19 vaccines due to high risk of death. In very rare instances, the COVID‐19 vaccines can induce anaphylaxis, and the management of anaphylaxis in older people should be considered carefully. An ARIA‐EAACI‐EuGMS (Allergic Rhinitis and its Impact on Asthma, European Academy of Allergy and Clinical Immunology, and European Geriatric Medicine Society) Working Group has proposed some recommendations for older adults receiving the COVID‐19 vaccines. Anaphylaxis to COVID‐19 vaccines is extremely rare (from 1 per 100,000 to 5 per million injections). Symptoms are similar in younger and older adults but they tend to be more severe in the older patients. Adrenaline is the mainstay treatment and should be readily available. A flowchart is proposed to manage anaphylaxis in the older patients.

Improving quality and performance in substance use treatment programs: What is being done and why is it so hard?

SUMMARY

As states plan to implement system-wide change of any kind, it is important to understand program directors' perspectives on challenges they face. This is especially true with quality improvement reforms. Much research has focused on quality improvement in medicine, but there is a gap in our knowledge about programs that treat individuals with drug or alcohol use. From 2007 to 2016, Maine contracted with selected substance use treatment programs using financial incentives to improve quality, with focus on treatment access, engagement, retention, and completion as measures of quality. Using surveys and in-depth interviews, this research documents strategies that programs used to improve performance and challenges faced in implementing reforms. Only programs that received federal block grant funding through the state to provide substance use treatment were eligible for an incentive contract, creating a natural experiment with non-block grant programs (non-incentive). Directors were interviewed in incentive (n=13) and non-incentive programs (n=12).

FINDINGS

Thematic analysis revealed that: 1) programs focused on QI, but those eligible for incentives focused on different quality measures, 2) most of the reforms in both groups targeted improving treatment access and retention, and 3) programs faced substantial challenges in undertaking reforms. Despite efforts, many programs could not meet quality measures consistently over time and faced barriers over which they had little control.

APPLICATIONS

Policy makers and program administrators will benefit from knowing the challenges of undertaking QI initiatives and provide support for the programs.

A socio-emotional analysis of technology use by people with intellectual disabilities

BACKGROUND

Access to information and communication technologies (ICTs) is often thought to enhance the lives of people with intellectual disabilities (ID) and is considered an important aspect of digital inclusion. However, inclusion practices often fail to address societal inequalities that lead to and sustain exclusion. The aim of this research was to enhance understandings of the relationships people with ID form with technology by critically analysing the underlying assumptions of inclusion practices.

METHOD

We employed a post-qualitative approach to reanalyse previously collected data from face-to-face interviews with 10 Australian adults with ID who attended a community literacy programme about their technology use in their daily lives. Two of social theorist Sara Ahmed's key concepts were used to analyse these data: (1) 'stickiness' of emotions, where certain (socially dominant) emotions are considered to attach to objects over time (e.g. mobile phone use is normal/good) and (2) 'fit' between people and objects, where there is a sense of comfort when objects are designed for people like you - those outside the 'norm' experience discomfort and a sense of being 'othered' in their interactions with such objects which do not fit them.

RESULTS

Our analysis identified how people with ID often attributed positive feelings to technology even when they had seemingly negative interactions with their devices (e.g. they could not use certain features, caregivers acted as gatekeepers to access). The positive associations were likely the outcome of implicitly held understandings that society highly values technology (Ahmed's stickiness of emotions). Although some participants accessed technology without difficulty, others experienced discomfort due to difficulties using devices that were not designed for them (Ahmed's fit between people and objects). Importantly, some participants had access to technology and the technical skill to use ICTs, but other factors, such as not having many friends, impacted their ability to use their devices in meaningful ways.

CONCLUSION

Our analysis suggests that digital inclusion practices focused on providing access to technology may unintentionally harm in ways that are not immediately apparent when working with people with ID. Harms might include further marginalisation or 'othering' of people with ID. It is important to recognise that well-meaning attempts to encourage use of ICTs may be counterproductive if they lead to experiences of marginalisation. To avoid this, inclusion practices could focus beyond access to devices, and the ability to use them, to include considerations of the multiple socio-emotional effects. What is a good fit is not entirely predeterminable, exploration of the possibilities for what will work well for any individual requires experimentation and creativity, and a careful attention to unintended effects. Beyond this, the development of new technology should consider how to diversify devices that often fail to fit people with disabilities.

Increased Risk of Autopsy-Proven Pneumonia with Sex, Season and Neurodegenerative Disease

There has been a markedly renewed interest in factors associated with pneumonia, a leading cause of death worldwide, due to its frequent concurrence with pandemics of influenza and Covid-19 disease. Reported predisposing factors to both bacterial pneumonia and pandemic viral lower respiratory infections are wintertime occurrence, older age, obesity, pre-existing cardiopulmonary conditions and diabetes. Also implicated are age-related neurodegenerative diseases that cause parkinsonism and dementia. We investigated the prevalence of autopsy-proven pneumonia in the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND), a longitudinal clinicopathological study, between the years 2006 and 2019 and before the beginning of the Covid-19 pandemic. Of 691 subjects dying at advanced ages (mean 83.4), pneumonia was diagnosed postmortem in 343 (49.6%). There were 185 subjects without dementia or parkinsonism while clinicopathological diagnoses for the other subjects included 319 with Alzheimer's disease dementia, 127 with idiopathic Parkinson's disease, 72 with dementia with Lewy bodies, 49 with progressive supranuclear palsy and 78 with vascular dementia. Subjects with one or more of these neurodegenerative diseases all had higher pneumonia rates, ranging between 50 and 61%, as compared to those without dementia or parkinsonism (40%). In multivariable logistic regression models, male sex and a non-summer death both had independent contributions (ORs of 1.67 and 1.53) towards the presence of pneumonia at autopsy while the absence of parkinsonism or dementia was a significant negative predictor of pneumonia (OR 0.54). Male sex, dementia and parkinsonism may also be risk factors for Covid-19 pneumonia. The apolipoprotein E4 allele, as well as obesity, chronic obstructive pulmonary disease, diabetes, hypertension, congestive heart failure, cardiomegaly and cigarette smoking history, were not significantly associated with pneumonia, in contradistinction to what has been reported for Covid-19 disease.

Loperamide exerts a direct bactericidal effect against M. tuberculosis, M. bovis, M. terrae and M. smegmatis

Tuberculosis (TB) is caused by Mycobacterium tuberculosis. TB is highly prevalent, characterized by the constant occurrence of drug-resistant cases, and confounded by the incidence of respiratory disease caused by non-tuberculous mycobacteria (NTB). Expanding the spectrum of drugs for the treatment of TB is indispensable. Loperamide, an antidiarrhoeal drug, enhances immune-driven antimycobacterial activity, and we aimed to evaluate its bactericidal activity against M. tuberculosis, Mycobacterium bovis BCG, Mycobacterium terrae and Mycobacterium smegmatis. Loperamide exhibited an inhibitory effect against all mycobacterial species tested, with MICs of 100 and 150 μg ml^-1 . Thus, loperamide is a mycobactericidal drug with potential as adjunctive therapy for TB and NTB infections.

Quality indicators of a cardiac rehabilitation program in women with coronary heart disease

Introduction

Cardiac rehabilitation programs (CRP) are well known to improve functional status and prognosis after a cardiovascular event. This programs are class IA recommendation. However, many studies have demonstrated that women are less likely to stick to a CRP.

Purpose

To compare baseline characteristics between men and women participating in a cardiac rehabilitation program and to determine whether there are gender differences in the benefits obtained after the program.

Methods

Using data from our Department of CRP, we analysed a total of 1091 patients referred between 2015 and 2018 to our center CRP after a cardiovascular diagnosis. Clinical, analytical and echocardiographic outcomes were collected. We defined benefit as the achievement of the target levels established for each cardiovascular risk factor (CVRF) as well as improvement in the exercise capacity. This capacity was evaluated with exercise tests and maximum O2 uptake at the beginning and at the end of the CPR.

Results

Between 2015 and 2018, 189 (17.3%) of them women with a mean age of 62 years were enrolled in the CRP. There were no significant gender differences in mean age or incidence of CVRF. Likewise, there weren't differences in cardiovascular diagnosis, risk stratification, left ventricular ejection fraction or exercise test performed before the program.

In the results after CRP there were no important gender differences in the percentage of patients who achieved the quality indicators described as HbA1c &lt;7.0%, systolic arterial pressure &lt;140 mmHg, diastolic arterial pressure &lt;90 mmHg. Percentage of LDL cholesterol &lt;70 mg/dl was significantly higher in male patients. Both in men and women an improvement of the second exercise test result was observed.

Conclusions

1. Men and women who suffer from a coronary heart disease have similar clinical characteristics.

2. Among patients with coronary heart disease who attended a cardiac rehabilitation program there were no significant gender differences in the benefits obtained after the program.

Characterization and validation of olive FAD and SAD gene families: expression analysis in different tissues and during fruit development

Stearoyl-ACP desaturases (SADs) and fatty acid desaturases (FADs) play a critical role in plant lipid metabolism and also affect oil fatty acid composition introducing double bonds into the hydrocarbon chains to produce unsaturated fatty acids. In the present study, the genomic sequences of three SAD and three FAD candidate genes were characterized in olive and their expression was evaluated in different plant tissues. OeSAD genes corresponded to olive SAD1 and SAD2 and to a newly identified OeSAD4, sharing the conserved protein structure with other plant species. On the other hand, the full-length genomic sequences of two microsomal OeFAD genes (FAD2-1 and FAD2-2) and the plastidial FAD6, were released. When the level of expression was tested on different tissues of cv. Leccino, OeSAD1 and OeSAD2 were mainly expressed in the fruits, while OeFAD genes showed the lowest expression in this tissue. The mRNA profiling of all genes was directly studied in fruits of Leccino and Coratina cultivars during fruit development. In both genotypes, the expression level of OeSAD1 and OeSAD2 had the highest value during and after the pit-hardening period, when oil accumulation in fruit mesocarp is intensively increasing. Furthermore, the expression level of both OeFAD2 genes, which were the main candidates for oleic acid desaturation, were almost negligible during fruit ripening. These results have made possible to define candidate genes of the machinery regulation of fatty acid composition in olive oil, providing information on their sequence, gene structure and chromosomal location.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 45 countries for 2012-2017: Device-associated module

BACKGROUND

We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific.

METHODS

During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied.

RESULTS

Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher.

CONCLUSIONS

Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.
