RESUMO

BACKGROUND: The relationship of microbiota composition dynamics and the progression of subclinical atherosclerosis in people with HIV (PWH) remains unknown. METHODS: 96-week, prospective, longitudinal study in virologically-suppressed PWH. Carotid intima-media thickness (cIMT) measurements and stool samples were obtained at baseline, 48-week and 96-week visits. cIMT progression was defined as an increase >10% and/or detection of new carotid plaque. To profile the gut microbiome, amplification and sequencing of 16S ribosomal-RNA (V3-V4 variable regions) were carried out following the Illumina protocol. Sequencing was performed with MiSeq platform. RESULTS: 191, 190 and 167 patients had available fecal samples for microbiome analysis at the baseline, 48- and 96-week visits, respectively. 87 (43%) participants showed atherosclerosis progression, and 54 (26.7%) presented new carotid plaque. No significant differences were observed in adjusted α-diversity indices between groups defined by cIMT progression. Beta-diversity determined through principal coordinate analysis distances showed that the groups exhibited distinct microbial profiles (PERMANOVA p-value = 0.03). Longitudinal analysis with ANCOM-BC2 adjusted for traditional cardiovascular risk factors, MSM and nadir CD4 count revealed that cIMT progression was consistently associated with Agathobacter and Ruminococcus_2, while non-progression was consistently associated with Prevotella_7. CONCLUSION: Progression of atherosclerosis in PWH might be associated with distinctive signatures in the gut microbiota.

RESUMO

This prospective study aimed to determine the prevalence of long COVID in patients hospitalized for SARS-CoV-2 infection from March 2020 to July 2022 and assess the impact of different viral lineages. A total of 2,524 patients were followed up for 12 months, with persistent symptoms reported in 35.2% at one month, decreasing thereafter. Omicron variant patients initially showed higher symptom intensity, but this trend diminished over time. Certain viral lineages, notably Delta lineages AY.126 and AY.43, and Omicron sublineages BA.1.17, BA.2.56, and BA.5.1, consistently correlated with more severe symptoms. Overall, long COVID prevalence and severity were similar across SARS-CoV-2 variants. Specific lineages may influence post-COVID sequelae persistence and severity.

RESUMO

OBJECTIVE: To assess the degree of implementation of cancer screening recommendations in people living with HIV (PLHIV) in Spain. METHODS: A self-administered questionnaire was designed on the strategies used for early detection of the main types of cancer in PLHIV. The survey was distributed electronically to HIV physicians participating in the Spanish CoRIS cohort. RESULTS: 106 questionnaires were received from 12 different Spanish Autonomous Communities, with an overall response rate among those who accessed the questionnaire of 60.2%. The majority responded that they followed the CPGs recommendations for the early detection of liver (94.3%), cervical (93.2%) and breast (85.8%) cancers. In colorectal and anal cancer, the proportion was 68.9% and 63.2%, and in prostate and lung cancer of 46.2% and 19.8%, respectively. In hospitals with a greater number of beds, a tendency to perform more cancer screening and greater participation of the Infectious Diseases/HIV Services in the screening programmes was observed. Significant differences were observed in the frequency of colorectal and anal cancer screening among the different Autonomous Communities. The most frequent reasons for not performing screening were the scarcity of material and/or human resources and not being aware of what is recommended in the CPGs. CONCLUSIONS: There are barriers and opportunities to expand cancer screening programmes in PLHIV, especially in colorectal, anal and lung cancers. It is necessary to allocate resources for the early detection of cancer in PLHIV, but also to disseminate CPGs screening recommendations among medical specialists.

RESUMO

IMPORTANCE: The cellular immune response is essential in the protection against severe disease in patients with established SARS-CoV-2 infection. The novelty of this study lies in the evaluation of the overall performance of a standardized assay to measure cellular immune response, the SARS-CoV-2-specific interferon-γ release assay (IGRA), in hospitalized patients with severe COVID-19. The SARS-CoV-2 IGRA was shown to accurately classify patients based on disease severity and prognosis, and the study revealed that test performance was not affected by the SARS-CoV-2 variant or control tube results. We identified an assay cut-off point with a high negative predictive value against mortality. The SARS-CoV-2 IGRA in patients hospitalized for COVID-19 may be a useful tool to assess cellular immunity and adopt targeted therapeutic and preventive measures.

RESUMO

BACKGROUND: We measured T-cell and antibody responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vaccinated patients hospitalized for coronavirus disease 2019 (COVID-19) and explored their potential value to predict outcomes. METHODS: This was a prospective, longitudinal study including vaccinated patients hospitalized with Delta and Omicron SARS-CoV-2 variants. TrimericS-IgG antibodies and SARS-CoV-2 T-cell response were measured using a specific quantitative interferon-γ release assay (IGRA). Primary outcome was all-cause 28-day mortality or need for intensive care unit (ICU) admission. Cox models were used to assess associations with outcomes. RESULTS: Of 181 individuals, 158 (87.3%) had detectable SARS-CoV-2 antibodies, 92 (50.8%) showed SARS-CoV-2-specific T-cell responses, and 87 (48.1%) had both responses. Patients who died within 28 days or were admitted to ICU were less likely to have both unspecific and specific T-cell responses in IGRA. In adjusted analyses (adjusted hazard ratio [95% confidence interval]), for the entire cohort, having both T-cell and antibody responses at admission (0.16 [.05-.58]) and Omicron variant (0.38 [.17-.87]) reduced the hazard of 28-day mortality or ICU admission, whereas higher Charlson comorbidity index score (1.27 [1.07-1.51]) and lower oxygen saturation to fraction of inspired oxygen ratio (2.36 [1.51-3.67]) increased the risk. CONCLUSIONS: Preexisting immunity against SARS-CoV-2 is strongly associated with patient outcomes in vaccinated individuals requiring hospital admission for COVID-19. Persons showing both T-cell and antibody responses have the lowest risk of severe outcomes.

RESUMO

Objetivo: El objetivo general del estudio fue describir las experiencias de las matronas en el acompañamiento a mujeres con miedo al parto (MAP). Método: Se planteó un estudio observacional, descriptivo, de corte transversal, donde la población a estudio fueron las matronas de la Unidad de Paritorio del Hospital Materno Infantil de Gran Canaria. Los datos se obtuvieron mediante un cuestionario estructurado ad hoc que incluía variables sobre la experiencia profesional en el acompañamiento intraparto de mujeres con MAP. Resultados: Participaron un total de 83 matronas, que identificaron como factores más frecuentes relacionados con el MAP en la práctica clínica el miedo a las complicaciones del recién nacido (90,4 %), la solicitud de cesárea (77,1 %) y la solicitud precoz de analgesia epidural (88,0 %). Con el objetivo de disminuir la ansiedad o la posibilidad de experiencia traumática, todas las matronas (n= 84) intervienen conscientemente creando un espacio de paz y escucha activa. Las mujeres con MAP producen mayormente sentimientos de empatía (80,7 %) y compasión (41 %). El 64 % de las matronas se mostró totalmente de acuerdo con la afirmación «Guiar a mujeres con miedo al parto es un desafío interesante». Conclusiones: Los resultados de este estudio evidencian que las matronas que acompañan a las mujeres intraparto son sensibles a esta problemática y se muestran motivadas para su abordaje, detectando de manera subjetiva indicadores que las alertan de que la mujer pueda tener miedo, y que este MAP puede estar asociado a consecuencias adversas. Aunque en ciertas situaciones preguntan a la mujer por su MAP, los factores que las inducen a ello presentan mucha variabilidad. (AU)


Objective: The general objective of the study was to describe the experiences of midwives in accompanying women with fear of childbirth (FOC). Method: An observational, descriptive, cross-sectional study was proposed, where the study population was the midwives of the delivery unit of the Maternal and Child Hospital of Gran Canaria. The data was obtained through a structured “ad hoc” questionnaire that included variables on professional experience in intrapartum monitoring of women with APM. Results: A total of 83 midwives participated, identifying fear of newborn complications (90.4%), request for cesarean section (77.1%), and early request for epidural analgesia (88.0%). In order to reduce anxiety or the possibility of a traumatic experience, all midwives (n=84) consciously intervene by creating a space for peace and active listening. Women with FOC produce more feelings of empathy (80.7%) and compassion (41%). 64% of midwives fully agreed with the statement “Guiding women with fear of childbirth is an interesting challenge”. Conclusions: The results of this study show that midwives who accompany intrapartum women are sensitive to this problem and are motivated to address it, subjectively detecting indicators that alert them that the woman may be afraid, and that this FOC may be associated with adverse consequences. Although in certain situations they ask the woman about her FOC, the factors that lead them to do so are highly variable. (AU)

RESUMO

Background: The pathophysiology of long-COVID remains unknown, and information is particularly limited for symptoms of very long duration. We aimed to assess the serological, T-cell immune responses and ANA titers of patients with long-COVID-19 syndrome of 1-year duration. Methods: Prospective, longitudinal study of hospitalized COVID-19 patients followed-up for 12 months. Sequential blood samples and COVID-19 symptom questionnaires (CSQ) were obtained, and humoral and cellular immune responses, antinuclear antibodies (ANA) and inflammation biomarkers were analyzed. Results: Of 154 patients discharged from hospital, 72 non-vaccinated with available CSQ in all visits were included. Of them, 14 (19.4%) reported persistent symptoms both at 6-months and 12-months, mainly asthenia (15.3%), myalgia (13.9%), and difficulty concentrating/memory loss (13.9%). Symptomatic patients were more frequently women, smokers, showed higher WHO severity score, and a trend to higher ICU admission. In the adjusted analysis, long-COVID syndrome was associated with lower frequency of detectable neutralizing antibodies (adjusted hazard ratio [aHR] 0.98; 95% confidence interval [CI], 0.97-0.99) and lower SARS-CoV-2-S1/S2 titers (aHR [95%CI] 0.14 [0.03-0.65]). T-cell immune response measured with a SARS-CoV-2-interferon-γ release assay was not different between groups. There was a higher frequency of positive ANA titers (≥160) in symptomatic patients (57.1% vs 29.3%, p=0.04), that was attenuated after adjustment aHR [95% CI] 3.37 [0.84-13.57], p=0.087. Levels of C-reactive protein and D-dimer were higher during follow-up in symptomatic patients, but with no differences at 12 months. Conclusion: Patients with 1-year duration long-COVID-19 syndrome exhibit a distinct immunologic phenotype that includes a poorer SARS-CoV-2 antibody response, low-degree chronic inflammation that tends to mitigate, and autoimmunity.

RESUMO

BACKGROUND: Mycobacterium africanum is a member of the Mycobacterium tuberculosis complex (MTBC) and is endemic in West Africa, where it causes up to half of all cases of pulmonary tuberculosis. Here, we report the first isolation of Mycobacterium africanum from the pericardial effusion culture of a patient with tuberculous pericarditis. CASE PRESENTATION: A 31-year-old man, native from Senegal, came to the emergency room with massive pericardial effusion and cardiac tamponade requiring pericardiocentesis. M. africanum subtype II was identified in the pericardial fluid. The patient completed 10 months of standard treatment, with a favorable outcome. CONCLUSIONS: We report the first case of tuberculous pericarditis caused by Mycobacterium africanum, which provide evidence that this microorganism can cause pericardial disease and must be considered in patients from endemic areas presenting with pericardial effusion.

RESUMO

BACKGROUND: Whether interleukin-6 (IL-6) blockade in patients with COVID-19 will affect the protective immunity against SARS-CoV-2 has become an important concern for anti-IL-6 therapy. We aimed to investigate the effects of IL-6 blockade on long-term immunity to SARS-CoV-2. METHODS: Prospective, longitudinal cohort study conducted in patients hospitalized for severe or critical COVID-19 with laboratory confirmed SARS-CoV-2 infection. We assessed humoral (anti-S1 domain of the spike [S], anti-nucleocapsid [N], anti-trimeric spike [TrimericS] IgG, and neutralizing antibodies [Nab]) and T-cell (interferon-γ release assay [IGRA]) responses and evaluated the incidence of reinfections over one year after infection in patients undergoing IL-6 blockade with tocilizumab and compared them with untreated subjects. FINDINGS: From 150 adults admitted with confirmed SARS-CoV-2 infection, 78 were 1:1 propensity score-matched. Patients receiving anti-IL6 therapy showed a shorter time to S-IgG seropositivity and stronger S-IgG and N-IgG antibody responses. Among unvaccinated subjects one year after infection, median (Q1-Q3) levels of TrimericS-IgG (295 vs 121 BAU/mL; p = 0.011) and Nab (74.7 vs 41.0 %IH; p = 0.012) were higher in those undergoing anti-IL6 therapy, and a greater proportion of them had Nab (80.6% vs 57.7%; p = 0.028). T-cell immunity was also better in those treated with anti-IL6, with higher median (Q1-Q3) interferon-γ responses (1760 [702-3992] vs 542 [35-1716] mIU/mL; p = 0.013) and more patients showing positive T-cell responses in the IGRA one year after infection. Patients treated with anti-IL6 had fewer reinfections during follow-up and responded to vaccination with robust increase in both antibody and T-cell immunity. INTERPRETATION: IL-6 blockade in patients with severe COVID-19 does not have deleterious effects on long-term immunity to SARS-CoV-2. The magnitude of both antibody and T-cell responses was stronger than the observed in non-anti-cytokine-treated patients with no increase in the risk of reinfections.

RESUMO

OBJECTIVES: To assess the benefits of remdesivir in hospitalized COVID-19 patients receiving combined immunomodulatory therapy (CIT) with dexamethasone and tocilizumab. METHODS: This was a cohort study of microbiologically confirmed COVID-19 hospitalized patients. The primary outcome was all-cause 28 day mortality. Secondary outcomes were need for invasive mechanical ventilation (IMV) and IMV/death. Subgroup analyses according to SARS-CoV-2 cycle threshold (Ct) values and inflammation biomarkers were performed. Multivariable marginal structural Cox proportional hazards regression models were used to analyse the association between remdesivir therapy and the risk of outcomes of interest. RESULTS: Of 1368 hospitalized patients treated with corticosteroids, 1014 (74%) also received tocilizumab, 866 (63%) remdesivir and 767 (56%) tocilizumab + remdesivir. The 28 day mortality was 9% in the overall cohort, with an adjusted HR (aHR) of 0.32 (95% CI = 0.17-0.59) for patients receiving CIT. In the latter group, the 28 day mortality was 6.5%, with an aHR of 1.11 (95% CI = 0.57-2.16) for remdesivir use and there were no differences in secondary outcomes. The risk of primary and secondary outcomes with remdesivir differed by Ct and C-reactive protein (CRP) levels in patients receiving CIT: for 28 day mortality, the aHR was 0.48 (95% CI = 0.21-1.11) for Ct <25, 0.12 (95% CI = 0.02-0.66) for Ct <25 and <5 day symptom duration and 0.13 (95% CI = 0.03-0.50) for CRP <38 mg/L; for IMV and IMV/death, the aHR was 0.32 (95% CI = 0.13-0.77) and 0.33 (95% CI = 0.17-0.63), respectively, in patients with Ct <25. CONCLUSIONS: The benefits of remdesivir administered with dexamethasone and tocilizumab in hospitalized COVID-19 patients differ depending on Ct and CRP. Remdesivir decreases the risk of mortality and need for IMV in patients with high viral loads and low-grade systemic inflammation.

RESUMO

OBJECTIVE: The aims of this study were to assess COVID-19 outbreak-related emotions, to identify vulnerable groups within health care workers (HCW) and to study the relationship between the emotional state and some environmental features. METHOD: We conducted a cross-sectional study on March 29 to April 5, 2020 based on a national online survey using snowball sampling techniques. A list of emotional states was compared in HCW and non-HCW and within HCW roles. The relationship between COVID-19 related symptoms, information, and protective measures and the emotional state was analyzed. RESULTS: Fear (p < .001, φc = .11), irritability (p = .001, φc = .08), frustration (p < .001, φc = .10), anger (p = .013, φc = .06), and helplessness (p < .001, φc = .13) appear significantly more frequently in HCW compared to non-HCW. Within HCW, a higher percentage of physicians, especially the less experienced, significantly perceived uncertainty and frustration (p = .001, φc = .13 and p = .025, φc = .10, respectively), while a higher percentage of nurses significantly experienced sadness (p = .024, φc = .10). Having a confirmatory diagnosis of the disease was related to hypochondria sensation (p = .026, φc = .10). Sadness (p = .035, φc = .09), intolerance (p = .058, φc = .09), anger (p = .024, φc = .10), and helplessness (p = .028, φc = .10) appeared as the most relevant emotions when information was perceived as insufficient. CONCLUSIONS: The knowledge of the most prevalent different emotional patterns in HCW, as well as in the general population, will allow the detection of subjects at risk for the development of mental disorders and the implementation of therapeutic approaches in future similar situations of pandemic or outbreak of the current one.

RESUMO

BACKGROUND: We evaluated a standardized interferon-γ (IFN-γ) release assay (IGRA) for detection of T-cell immune response after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or vaccination. METHODS: This prospective study included patients with coronavirus disease 2019 (COVID-19) with different severity of illness and follow-up (FU), vaccinated subjects, and healthy unvaccinated persons. SARS-CoV-2 T-cell response was measured using a specific quantitative IGRA in whole blood (Euroimmun, Germany) and TrimericS-IgG and neutralizing antibodies with validated serological platforms. Positivity of reverse transcription-polymerase chain reaction or vaccination was considered as the reference standard. RESULTS: A total of 239 individuals were included (152 convalescent, 54 vaccinated, and 33 uninfected unvaccinated). Overall sensitivity, specificity, and positive- and negative-predictive values (95% confidence interval) of the IGRA were 81.1% (74.9-86%), 90.9% (74.5-97.6%), 98.2% (94.5-99.5%), and 43.5% (31.8-55.9%), respectively. All vaccinated SARS-CoV-2-naive subjects had positive IGRA at 3 months. In convalescent subjects the magnitude of IFN-γ responses and IGRA accuracy varied according to disease severity and duration of FU, with the best performance in patients with severe COVID-19 at 3 months and the worst in those with mild disease at 12 months. The greatest contribution of IGRA to serological tests was observed in patients with mild disease and long-term FU (incremental difference, 30.4%). CONCLUSIONS: The IGRA was a reliable method of quantifying T-cell response after SARS-COV-2 infection or vaccination. In convalescent patients, the sensitivity is largely dependent on disease severity and time since primary infection. The assay is more likely to add clinical value to serology in patients with mild infections.

RESUMO

Background: Baricitinib is a Janus kinase (JAK) inhibitor with a broader anti-inflammatory activity than tocilizumab and an antiviral potential although no head-to-head trials are available. The benefits of adding baricitinib to patients with COVID-19 experiencing clinical progression despite the standard of care (SOC), including corticosteroids and tocilizumab, are also unknown. Methods: A cohort study included microbiologically confirmed COVID-19 hospitalizations. The primary outcome was 28-day mortality. Secondary outcomes were 60- and 90-day mortality, the composite outcome "28-day invasive mechanical ventilation (IMV) or death" and the safety of the combination. Propensity score (PS) matching was used to identify the association between baricitinib use and the outcomes of interest. Results: Of 1,709 admissions, 994 patients received corticosteroids and tocilizumab and 110 of them received baricitinib after tocilizumab. PS matched 190 (95:95) patients with baricitinib + SOC vs. SOC, of whom 69.5% received remdesivir. No significant effect of baricitinib was observed on 28-day [39 events; adjusted hazard ratio (aHR), 0.76; 95% CI, 0.31-1.86], 60-day (49 events, aHR, 1.17; 95% CI, 0.55-2.52), or 90-day mortality (49 events; aHR, 1.14; 95% CI, 0.53-2.47), or on the composite outcome 28-day IMV/death (aHR, 0.88; 95% CI, 0.45-1.72). Secondary infections during hospitalization were not different between groups (17.9 vs. 10.5%, respectively; p = 0.212) and thromboembolic events were higher with baricitinib (11.6% vs. 3.2%; p = 0.048), but differences vanished after the adjustment [aHR 1.89 (0.31-11.57), p = 0.490]. Conclusion: The addition of baricitinib did not substantially reduce mortality in hospitalized patients with COVID-19 having clinical progression despite the therapy with tocilizumab and corticosteroids. The combination of baricitinib and tocilizumab was not associated with an increased risk of secondary infections or thromboembolic events.

RESUMO

OBJECTIVES: Durability of the humoral immune response to SARS-CoV-2 has yet to be defined. We longitudinally evaluated during a 12-month period the antibody responses to SARS-CoV-2, and analysed predictors of antibody titres decline and seroreversion. METHODS: Prospective study conducted in a cohort of patients hospitalized for microbiologically-confirmed COVID-19. Blood and nasopharyngeal samples were sequentially obtained during hospital stay and at 1, 2, 6 and 12 months after patients' discharge for measuring anti-spike (S) and anti-nucleocapsid (N) IgG antibody levels and SARS-CoV-2 RNA, respectively. RESULTS: 80 non-vaccinated patients were analysed. At month 12 after discharge, 73 (91.2%) patients exhibited detectable S-IgG and 35 (43.8%) N-IgG antibody titres. A gradual wane was observed in S-IgG and N-IgG antibody titres. Linear regression showed that S-IgG decline was positively associated with peak antibody titres (coefficient [95% CI] 0.059 [0.05-0.067], p < 0.001), inversely with WHO severity score (coefficient [95% CI] -0.042 [-0.079/-0.004], p = 0.033), and there was a trivial positive association with age (coefficient [95% CI] 0.002 [0-0.005], p = 0.10); N-IgG decline was positively associated with peak antibody titres (coefficient [95% CI] 0.091 [0.078-0.105], p < 0.001). Logistic regression showed that seroreversion for S-IgG was inversely associated with peak S-IgG (OR 0.19; 95% CI, 0.04-0.45; p = 0.004); seroreversion for N-IgG was inversely associated with peak N-IgG (OR 0.71; 95% 0.53-0.90; p = 0.009) and positively with cycle threshold of RT-PCR (OR 1.14; 95% CI, 1.00-1.33; p = 0.062). CONCLUSION: Anti-spike IgG antibodies remain detectable one year after hospitalization for COVID-19. Higher peak antibody titres and disease severity were associated with increased durability of detectable antibodies.

RESUMO

BACKGROUND: The relationship of host immune response and viral replication with health outcomes in patients with COVID-19 remains to be defined. We aimed to characterize the medium and long-term clinical, virological, and serological outcomes after hospitalization for COVID-19, and to identify predictors of long-COVID. METHODS: Prospective, longitudinal study conducted in COVID-19 patients confirmed by RT-PCR. Serial blood and nasopharyngeal samples (NPS) were obtained for measuring SARS-CoV-2 RNA and S-IgG/N-IgG antibodies during hospital stay, and at 1, 2, and 6 months post-discharge. Genome sequencing was performed where appropriate. Patients filled out a COVID-19 symptom questionnaire (CSQ) at 2-month and 6-month visits, and those with highest scores were characterized. RESULTS: Of 146 patients (60% male, median age 64 years) followed-up, 20.6% required hospital readmission and 5.5% died. At 2 months and 6 months, 9.6% and 7.8% patients, respectively, reported moderate/severe persistent symptoms. SARS-CoV-2 RT-PCR was positive in NPS in 11.8% (median Ct = 38) and 3% (median Ct = 36) patients at 2 months and 6 months, respectively, but no reinfections were demonstrated. Antibody titers gradually waned, with seroreversion occurring at 6 months in 27 (27.6%) patients for N-IgG and in 6 (6%) for S-IgG. Adjusted 2-month predictors of the highest CSQ scores (OR [95%CI]) were lower peak S-IgG (0.80 [0.66-0.94]) and higher WHO severity score (2.57 [1.20-5.86]); 6-month predictors were lower peak S-IgG (0.89 [0.79-0.99]) and female sex (2.41 [1.20-4.82]); no association was found with prolonged viral RNA shedding. CONCLUSIONS: Long-COVID is associated with weak anti-SARS-CoV-2 antibody response, severity of illness, and female gender. Late clinical events and persistent symptoms in the medium and long term occur in a significant proportion of patients hospitalized for COVID-19.

RESUMO

Objetivo: Identificar las actitudes y la calidad subjetiva percibida por las mujeres después del uso de analgesia epidural en el parto. Metodología: Estudio transversal, observacional, descriptivo y analítico realizado en el Hospital Universitario Materno Infantil de Gran Canaria, donde la población de estudio fueron las puérperas que recibieron analgesia epidural durante el parto entre agosto y octubre de 2019. Se utilizaron un muestreo consecutivo no probabilístico y un cuestionario autoadministrado. Se realizaron un análisis descriptivo de las variables y un análisis inferencial para explorar la asociación entre diferentes variables. Resultados: La muestra final estuvo constituida por 354 mujeres. Las mujeres consideraron que la información recibida por las matronas era la más importante (57,6%), y el 20,3% percibió un retraso en la administración de analgesia epidural después de su solicitud. Se obtuvo una puntuación media respecto a la satisfacción global materna de 24,45 (desviación estándar= 4,97; máxima 28; mínima 0). Se encontró una relación estadísticamente significativa entre la satisfacción global y el nivel educativo (p= 0,019*), y entre la lectura y el entendimiento previo del consentimiento informado y la satisfacción global materna (p <0,001*). La percepción de demora en la administración influye de forma negativa en la satisfacción (p= 0,003*). Conclusiones: Un número elevado de mujeres que inicialmente no se planteaban la analgesia epidural en el parto acabó optando por ella, con un nivel alto de satisfacción y calidad percibida después de su uso.

Objective: To identify labouring women’s attitudes and subjective quality after the use of epidural analgesia. Methodology: Observational, descriptive analytical cross-sectional study at the Mother and Children’s University Hospital of Gran Canaria, with a study population of postnatal women who received epidural analgesia during delivery between August and October 2019. A non-probabilistic consecutive sample and a self-administered questionnaire were used. A descriptive analysis of the collected variables and an inferential analysis was performed to explore the association between different variables. Results: From a sample of 354 women. Women considered the information received by midwives more important (57.6%) and 20.3% perceived a delay in the administration of epidural analgesia after their request. An average score of 24,45 regarding maternal global satisfaction was obtained (SD= 4.97; maximum 28; minimum 0). A statistically significant relationship was found between global satisfaction and educational level (p= 0.019*) and between reading and prior understanding of informed consent and overall maternal satisfaction (p <0.001*). Delay perception in the administration of the epidural negatively influenced satisfaction (p= 0.003*). Conclusions: A high number of women who initially did not consider epidural analgesia in childbirth end up opting for it, the level of satisfaction and quality perceived after its use being high.

RESUMO

Public health studies warn of the vulnerability of people with mental disorders during the COVID-19 outbreak. Thus, the aims of this study were to (1) explore the presence of symptoms of anxiety, depression and acute stress among people with a mental disorder (MD); (2) evaluate the rate of COVID-19 infection between MD and non-MD, and (3) study the relationship between the emotional state of people with a mental disorder and some environmental variables. A cross-sectional study starting on March 29 to April 5, 2020 based on a national online survey using snowball sampling techniques was conducted. Symptoms of anxiety (Hamilton Anxiety Scale), depression (Beck Depression Inventory) and acute stress (Acute Stress Disorder Inventory) were compared in MD and non-MD. The rate of COVID-19 confirmed cases among MD and non-MD was compared as well as the relationship between some environmental variables and the emotional state within MD. Up to 1839 [201 (10.9%) MD] participants completed the survey. MD showed significant higher mean (SD) in anxiety [24.7 (11.8) vs. 17 (10.3); p = 0.001], depression [7.9 (6.0) vs. 4.2 (4.2); p = 0.001] and acute stress [6.3 (3.2) vs. 4.4 (3.1); p = 0.001] scores than non-MD. The COVID-19 confirmed cases rate was higher in MD participants than in non-MD (3.5% vs. 0.4%; p < 0.001). Among the MD group, being a COVID-19 confirmed case, the lack in basic needs coverage, the rpesence of violence, drug use and the absence of physical excercise were associated with more severe depressive symptoms. Findings suggest that the COVID-19 has an impact on the emotional state of people with mental disorders.
