ABSTRACT
Purpose: The objective of the research is proposed a methodology to prepare a Zero-Based Budget ( ZBB) for Small and Medium-sized Enterprises (SMEs) in Ecuador, applying fuzzy logic. Design/methodology/approach: A quantitative approach is assumed to show findings derived from the work carried out in these Ecuadorian business units, belonging to non-essential sectors such as wood, textiles and footwear. Fuzzy logic, the technique of expertise, and Trapezoidal Fuzzy Numbers ( TpFN) are used to capture true budget levels. Findings: The results recommend that optimal budget levels can be obtained for SMEs in restrictive and health emergency contexts. Originality/value: As a result of COVID-19 pandemic, markets and demand are contracting causing variations in income and demanding greater rationalization at the level of expenditures. For SMEs is essential prepared income and disbursements estimates. Based on the methodology proposed, predictions are made to achieve the objectives of SMEs. Directors will be able to make more successful decisions for the benefit of their companies, to streamline operations, direct the achievement of objectives, rationalize expenses (costs and expenses), and to project better scenarios in the future before carrying out cost-benefit analysis.
ABSTRACT
Introduction: During the COVID-19 pandemic, the number of patients who required admission to the intensive care unit (ICU) and prolonged intubation (ETI) or a tracheotomy (TT) due to severe ARDS has increased. Causes of persistent dyspnea after severe COVID-19 pneumonia include diffuse lung disease and pulmonary embolism. However, other causes of persistent dyspnea need to be ruled out in COVID-19 ICU-survivors, including iatrogenic tracheal stenosis (TS). Iatrogenic TS account for 50% of the 15-20 patients evaluated every year in the laryngotracheal multidisciplinary team (MDT) of our center. The management of these patients requires an individualized and multidisciplinary assessment, including Interventional Pulmonologists, Thoracic Surgeons and Otolaryngologists. The objective of this study was to describe the cases of iatrogenic TS after severe pneumonia due to COVID-19. Material(s) and Method(s): A descriptive study of the cases of iatrogenic TS in COVID-19 ICU-survivors evaluated at our center's MDT, from the end of the first wave to present. Result(s): A total of 10 patients were included, 70% were women, with a median age of 60 years [53.5-64.5]. The median ICU stay was 58.5 days [34-91]. All patients were intubated and 9 of them (90%) required TT, in 2 cases due to extubation failure. Symptoms at diagnosis included dyspnea in 3 (30%), stridor in 6 (60%) and 1 (10%) was asymptomatic. TS location was glottic in 2 (20%) and tracheal in 8 (80%). The main cause of TS was ring fracture secondary to TT (40%). Conclusion(s): Iatrogenic TS is a rare cause of dyspnea in COVID-19 ICU-survivors, but it must be considered in these patients given the high number of patients who required prolonged ETI or TT during the COVID-19 pandemic.
ABSTRACT
Background: In outpatients, monoclonal antibodies to Spike protein reduce viral load and improve outcomes, with a greater effect in serum antibody-negative at baseline. The aim of this study was to find epitope candidates to produce neutralizing monoclonal antibodies (mAb) for COVID-19 treatment. Method(s): IgG COVID-19 patients (N=500) against SARS-CoV-2 was confirmed. Epitope mapping was performed by Luminex technology. A computational pipeline based in predictive models was designed to predict S protein epitopes most likely to be recognized by mAb from COVID-19 convalescent patients. Result(s): Validation Screening: 29 epitopes of the SARS-CoV-2 S protein were predicted by our pipeline and included in the Luminex panel. 40 serum samples from convalescent COVID-19 patients and 126 pre-pandemia negative controls were included in the validation screening. Epitope mapping: 500 serum samples were tested against the 8 epitopes selected in the validation screening. The two epitopes with the highest IgG of participants above the seropositivity cut-offs were selected. The two most immunogenic epitopes were screened in phage library containing 109 clones of antibodies anti-SARS-CoV-2 to produce mAbs by phage display technology. Conclusion(s): The two epitopes with the highest IgG reactivity validated against serum samples from 500 COVID-19 convalescent patients and phage library are good candidates for the production of new neutralizing mAbs against SARS-CoV-2 S protein.
ABSTRACT
Background: Mechanical complications (MC) give a poor prognosis for ST elevation myocardial infarction (STEMI). Its prevalence had decreased in the era of primary angioplasty, at the expense of free wall rupture (FWR). Purpose: To analyse the prevalence of post-STEMI MC for two periods, before and after the COVID-19 pandemic. Methods: Unicentric prospective registration of patients with STEMI admitted between January-2018 and December-2021. They are classified into two groups according to the onset of the pandemic by COVID-19: Pre-COVID: January-2018 to December-2019, and Post-COVID: January-2020 to December-2021. The prevalence of post-STEMI MC is analysed, including ventricular septal rupture (VSR), papillary muscle rupture (PMR) and FWR, and 30-day mortality. Results: 1507 consecutive patients with STEMI (Pre-COVID n=775, Post-COVID n=732) are included. Age 62.9 years vs 63.3 years (p=0.5097). Men 78.1% Vs 79.5% (p=0.493). No differences in cardiovascular risk factors, previous heart infarction or anterior wall STEMI. Primary angioplasty was similar in both groups (92%). The Post-COVID group has a higher prevalence of Killip>I (21.7% vs 17.2% p=0.025) and LVEF ≤40% (27.2% vs 20% p=0.001), and longer symptom onset to balloon dilatation interval (316 min vs 257 min p=0.0004). MC are most developed in Post-COVID (2.6% vs 1.2% p=0.039), at the expense of FWR (1.91% vs 0.3% p=0.001). No significant changes in VSR and PMR prevalence or 30-day mortality. Multivariate analysis identifies the independent predictors of FWR: Age (OR 1.05, p=0.024), Primary angioplasty (OR 0.09, p<0.001), and Post-COVID (OR 6.8, p=0.013). Conclusions: The COVID-19 pandemic is independently associated with a higher prevalence of FWR, probably due to delayed reperfusion. Funding Acknowledgement: Type of funding sources: None.
ABSTRACT
Background Hand hygiene (HH) is one of the main preventive methods for healthcare-associated infections. Our aim is to compare the level of HH compliance in 2021, SARS-CoV-2 pandemic period, with the previous 2019 period. Methods Descriptive cross-sectional study of direct observation on compliance of HH in adult intensive care unit (AICU) and neonatal intensive care unit (NICU) in a third-level hospital in Madrid during the years 2019 and 2021. Trained healthcare workers observed and recorded hand hygiene opportunities (HHO) among staff (nurse, nurses’ aide, physicians and orderly) using the World Health Organization's “My Five Moments for Hand Hygiene” tool. All observations of professional that attended patients in SARS-CoV-2 isolation units were excluded. Results Overall, there was a total of 1199 HHO, 961 in AICU (2019:466;2021:495) and 238 in NICU (2019:122;2021:116). HH compliance in AICU improved from 57.5% in 2019 to 65.9% in 2021 (p = 0.008) and remained unchanged in NICU (2019:90.2% vs 2021:88.8%;p = 0.730). In AICU all professional categories, except nurse’s aide, improved HH compliance being statistically significant in physicians (2019:33.8% vs 2021:50.0%;p = 0.009). In relation to the 5 moments, an increase in HH compliance was observed in: before and after touching a patient/after touching patient surroundings, being only statistically significant in moment after touching a patient (2019:69.4% vs 2021:83.7%;p = 0.001). In NICU there were no significant changes between the two periods regarding to the professional category or the five moments of HH. In NICU there were no significant changes between the two periods regarding to the professional category or the five moments of HH. Conclusions The increase in compliance of HH within the adult ICUs demonstrates this adaptation, stating a behavioural change in the habits of professionals. This increase was no observed in the NICU since their compliance was already extremely high. Key messages • There has been an increase in HH compliance in the AICU. • The HH method has varied, becoming COVID-19 specific.
ABSTRACT
Radiotherapy is an essential treatment in the local control of breast cancer. Standard treatment is currently carried out in 15 daily sessions. At present, following the results of the phase III Fast-Foward trial and in view of the situation triggered by COVID-19, the number of sessions has been reduced to 5. We present the data of our series to evaluate the results of the extreme hypofractionation scheme as a radiotherapy treatment for breast cancer at the Multihospital Clinical Unit of Radiation Oncology of Aragón (UCMORA). Materials and Methods After implantation, 115 patients were treated with 3D conformal radiotherapy between April 2020 and May 2021 at UCMORA using the extreme hypofractionation scheme (26 Gy at 5.2 Gy per fraction in 5 fractions). Demographic, tumor, dosimetric and toxicity characteristics were analyzed. Results The mean age was 63.5 years. 53 patients were treated at the Lozano Blesa Clinical Universitary Hospital and 62 at the Miguel Servet Universitary Hospital, in total 59 right and 56 left breasts. The predominant histology was infiltrating ductal carcinoma (84.3%), followed by infiltrating lobular carcinoma (10.4%), ductal carcinoma in situ (4.3%) and mucinous (0.9%). 51.7% were luminal A, 39.1% luminal B, 1.8% Her2 positive and 7.8% triple negative. In relation to staging, we found 4pTis, 8pT1a, 45pT1b, 58pT1c, 2Nx, 8N0, 1Nmi and 13N1a. Only 45% had acute toxicity at one month after the end of treatment, predominantly G1 radiodermatitis (86.6%), followed by G2 (11.2%) and G3 (2.2%). When analyzing the dose-volume histograms, values were obtained for ipsilateral lung V8 between 1.32 and 21.2%, for the heart, in case of left breast a median for V1.5 of 8.2% and 1.05% for V7;in case of right breast the median Dmed for the heart was 0.5Gy (Figure Presented) Conclusion Ultra-hypofractionated whole breast radiotherapy as a radiation treatment for breast cancer is well tolerated, reduces costs and number of sessions, while increasing comfort for patients.
ABSTRACT
Background: Arterial hypertension has been described as one of the main risk factors for poor prognosis in Covid-19. In this context, the role of angiotensin-converting enzyme 2 (ACE2) in this infection has been studied, with studies showing how this enzyme acts as a functional receptor for SARS-CoV-2, favoring the penetration of the virus into the cell. The main objective of this work is to study the impact of chronic antihypertensive treatment in a cohort of SARS-CoV-2 positive patients with arterial hypertension, as well as clinical outcomes during hospitalization. Method: Single-center observational retrospective cohort study conducted at a tertiary level university hospital from 1st March 2020 to 31st May 2020. All adult patients admitted with a diagnosis of COVID-19 and a history of arterial hypertension on chronic treatment with an antihypertensive drug during the three months prior to contracting the infection were included. For the analysis, patients were divided into three groups according to the chronic antihypertensive treatment they were receiving: angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin II receptor antagonists (ARB) or other treatment, excluding those patients who during the three months prior to the start of the study had been on concomitant treatment with ACE inhibitors and ARB, as well as those on treatment with more than four antihypertensive drugs. Results: A total of 475 cases with positive PCR for SARS-CoV-2 cases had hypertension as an associated comorbidity on antihypertensive treatment in the three months prior to admission. The mean age of this cohort of patients was 77.05 (SD 10.95) years, most of them male (56.8%) Regarding the prolonged length of stay variable, 127 patients (26.7%) were admitted for 14 days or more, with no statistically significant differences between the three groups. For patients admitted to the Intensive Care Unit (ICU) (29 patients, 6.1%) no differences were observed between the three study groups either.Regarding the outcome variable, all-cause in-hospital mortality, no statistically significant differences were observed between the groups (p = 0.836). Conclusions: Patients admitted with SARS-CoV2 respiratory infection with a diagnosis of hypertension and pre-admission treatment with an antihypertensive drug showed no statistically significant differences in mortality between those hypertensive patients who received renin-angiotensin-aldosterone system (RAAS) inhibitor antihypertensive drugs and those who received other antihypertensive treatments.

ABSTRACT
AIMS: Longitudinal data on the mental health impact of the coronavirus disease 2019 (Covid-19) pandemic in healthcare workers is limited. We estimated prevalence, incidence and persistence of probable mental disorders in a cohort of Spanish healthcare workers (Covid-19 waves 1 and 2) -and identified associated risk factors. METHODS: 8996 healthcare workers evaluated on 5 May-7 September 2020 (baseline) were invited to a second web-based survey (October-December 2020). Major depressive disorder (PHQ-8 ≥ 10), generalised anxiety disorder (GAD-7 ≥ 10), panic attacks, post-traumatic stress disorder (PCL-5 ≥ 7), and alcohol use disorder (CAGE-AID ≥ 2) were assessed. Distal (pre-pandemic) and proximal (pandemic) risk factors were included. We estimated the incidence of probable mental disorders (among those without disorders at baseline) and persistence (among those with disorders at baseline). Logistic regression of individual-level [odds ratios (OR)] and population-level (population attributable risk proportions) associations were estimated, adjusting by all distal risk factors, health care centre and time of baseline interview. RESULTS: 4809 healthcare workers participated at four months follow-up (cooperation rate = 65.7%; mean = 120 days s.d. = 22 days from baseline assessment). Follow-up prevalence of any disorder was 41.5%, (v. 45.4% at baseline, p < 0.001); incidence, 19.7% (s.e. = 1.6) and persistence, 67.7% (s.e. = 2.3). Proximal factors showing significant bivariate-adjusted associations with incidence included: work-related factors [prioritising Covid-19 patients (OR = 1.62)], stress factors [personal health-related stress (OR = 1.61)], interpersonal stress (OR = 1.53) and financial factors [significant income loss (OR = 1.37)]. Risk factors associated with persistence were largely similar. CONCLUSIONS: Our study indicates that the prevalence of probable mental disorders among Spanish healthcare workers during the second wave of the Covid-19 pandemic was similarly high to that after the first wave. This was in good part due to the persistence of mental disorders detected at the baseline, but with a relevant incidence of about 1 in 5 of HCWs without mental disorders during the first wave of the Covid-19 pandemic. Health-related factors, work-related factors and interpersonal stress are important risks of persistence of mental disorders and of incidence of mental disorders. Adequately addressing these factors might have prevented a considerable amount of mental health impact of the pandemic among this vulnerable population. Addressing health-related stress, work-related factors and interpersonal stress might reduce the prevalence of these disorders substantially. Study registration number: NCT04556565.

Healthcare workers (HCW) are at high risk for suicide, yet little is known about the onset of suicidal thoughts and behaviors (STB) in this important segment of the population in conjunction with the COVID-19 pandemic. We conducted a multicenter, prospective cohort study of Spanish HCW active during the COVID-9 pandemic. A total of n = 4809 HCW participated at baseline (May-September 2020; i.e., just after the first wave of the pandemic) and at a four-month follow-up assessment (October-December 2020) using web-based surveys. Logistic regression assessed the individual- and population-level associations of separate proximal (pandemic) risk factors with four-month STB incidence (i.e., 30-day STB among HCW negative for 30-day STB at baseline), each time adjusting for distal (pre-pandemic) factors. STB incidence was estimated at 4.2% (SE = 0.5; n = 1 suicide attempt). Adjusted for distal factors, proximal risk factors most strongly associated with STB incidence were various sources of interpersonal stress (scaled 0-4; odds ratio [OR] range = 1.23-1.57) followed by personal health-related stress and stress related to the health of loved ones (scaled 0-4; OR range 1.30-1.32), and the perceived lack of healthcare center preparedness (scaled 0-4; OR = 1.34). Population-attributable risk proportions for these proximal risk factors were in the range 45.3-57.6%. Other significant risk factors were financial stressors (OR range 1.26-1.81), isolation/quarantine due to COVID-19 (OR = 1.53) and having changed to a specific COVID-19 related work location (OR = 1.72). Among other interventions, our findings call for healthcare systems to implement adequate conflict communication and resolution strategies and to improve family-work balance embedded in organizational justice strategies.

Background: Influenza vaccination coverages among health care students are low. The aim of this study was to find out which measures, according to medical and nursing students, could contribute to improve these vaccination rates. Methods: A cross-sectional study that included medical and nursing students of the University of Zaragoza who were doing internships in health centers during the 2020-2021 school year. The information was obtained in December 2020 by a self-administered online questionnaire, in which they were asked to describe the measures that, in their opinion, are necessary to increase their influenza vaccination coverage. A qualitative analysis of the content of the answers was carried out, extracting themes, sub-themes and selecting the most representative verbatims. Results: The questionnaire was answered by 83 students (response rate: 5.9%);64 (77.1%) were women, and 74.7% of them were studying medicine. The main measures proposed were improving the accessibility of the vaccine, improving the training on influenza vaccine, promoting vaccination by the teaching staff, and increasing the diffusion of information about the vaccination campaign. Conclusions: This study has found measures to be applied specifically to medical and nursing students to potentially improve their influenza vaccination coverage. For its implementation, collaboration between universities and health services is necessary.
ABSTRACT
OBJECTIVE: To analyze the initial findings in chest X-rays of patients with RT-PCR positive for SARS-CoV-2, and to determine whether there is a relationship between the severity of these findings and the clinical and laboratory findings. MATERIALS AND METHODS: This retrospective study analyzed the relationship between initial chest X-rays and initial laboratory tests in symptomatic adults with nasopharyngeal RT-PCR results positive for SARS-CoV-2 seen at our center between February 29 and March 23, 2020. Among other radiologic findings, we analyzed ground-glass opacities, consolidations, linear opacities, and pleural effusion. We also used a scale of radiologic severity to assess the distribution and extent of these findings. Among initial laboratory findings, we analyzed leukocytes, lymphocytes, platelets, neutrophil-to-lymphocyte ratio, and C-reactive protein. RESULTS: Of 761 symptomatic patients, 639 (84%) required hospitalization and 122 were discharged to their homes. The need for admission increased with increasing scores on the scale of radiologic severity. The extent of initial lung involvement was significantly associated with the laboratory parameters analyzed (P<.05 for platelets, P<.01 for lymphocytes, and P<.001 for the remaining parameters), as well as with the time from the onset of symptoms (P<.001). CONCLUSION: It can be useful to use a scale of radiologic severity to classify chest X-ray findings in diagnosing patients with COVID-19, because the greater the radiologic severity, the greater the need for hospitalization and the greater the alteration in laboratory parameters.
