RESUMEN
Background: Nocardiosis, a bacterial opportunistic infection caused by Nocardia spp, has recently been reported in patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies, but insufficient data are available about disease presentation, outcomes, and occurrence of autoimmune pulmonary alveolar proteinosis (aPAP) in this population. Methods: We performed a prospective, multicenter, nationwide study in France and included patients with a Nocardia infection who had anti-GM-CSF autoantibodies. We describe their clinical, microbiological, and radiological characteristics, and their outcome at 1 year of follow-up. Results: Twenty patients (18 [90%] male) were included, with a median age of 69 (interquartile range, 44-75) years. The organs most frequently involved were the brain (14/20 [70%]) and the lung (12/20 [60%]). Half of the infections were disseminated (10/20 [50%]). Nocardia identification was predominantly made in abscess fluid (17/20 [85%]), among which 10 (59%) were brain abscesses. The 1-year all-cause mortality was 5% (1/20), and only 1 case of aPAP (1/20 [5%]) occurred during the follow-up period. Conclusions: Nocardiosis with anti-GM-CSF autoantibodies is associated with a low mortality rate despite a high incidence of brain involvement. Although the occurrence of aPAP was infrequent during the 1-year follow-up period, long-term clinical data are needed to fully understand the potential relationship between nocardiosis, anti-GM-CSF autoantibodies, and aPAP.
RESUMEN
The third, "booster", vaccination increases the overall immune response against SARS-CoV-2 variants. However, after the initial peak at around 3 weeks post-vaccination, anti-spike antibody levels decline. Post-booster kinetics of cellular response has been less investigated and there is no documented evidence of a true boosting effect. Furthermore, multiple studies underline the less effective immune responses against Omicron, the latest variant of concern, at both humoral and cellular levels. In this letter, we analyse humoral (anti-RBD IgG levels) and cellular (IFN-γ release assay) immune response in 205 health care workers 3 weeks and 3 months after administration of an mRNA-based booster dose, either mRNA-1273 or BNT162b2. Since all subjects were SARS-CoV-2 infection-naïve, we also looked at the incidence of Omicron infection between 3 and 6 months post-booster.At both timepoints, 3x mRNA-1273 vaccination had the highest overall antibody and IFN-γ levels, followed by 3x BNT162b2 vaccination and heterologous mRNA-based regimens. Heterologous ChAdOx1-mRNA-based regimen had the lowest antibody levels while cellular response equal to that of 3x BNT162b2 vaccination and heterologous mRNA-based regimens. Our results show that both humoral and cellular responses waned at 3 months for all vaccination regimens. However, we identified three trajectories of dosage variation. Interestingly, the subgroup of subjects with increasing anti-RBD IgG levels over time had a lower incidence of Omicron infection. Whether increasing humoral response at 3 months post-booster is more indicative of protection than a high initial peak remains to be confirmed in a larger cohort.

Clinical trials and real-world evidence on COVID-19 vaccines have shown their effectiveness against severe disease and death but the durability of protection remains unknown. We analysed the humoral and T-cell immune responses in 110 healthcare workers (HCWs) vaccinated according to the manufacturer's recommended schedule of dose 2 three weeks after dose 1 from a prospective on-going cohort in early 2021, 3 and 6 months after full vaccination with the BNT162b2 mRNA vaccine. Anti-RBD IgG titres were lower in HCWs over 60 years old 3 months after the second dose (p=0.03) and declined in all the subjects between 3 and 6 months with a median percentage change of -58.5%, irrespective of age and baseline comorbidities. Specific T-cell response measured by IGRA declined over time by at least 42% (median) in 91 HCWs and increased by 33% (median) in 17 others. Six HCWs had a negative T-cell response at 6 months. Ongoing follow-up should provide correlates of long-term protection according to the different immune response profiles observed. COVIDIM study was registered under the number NCT04896788 on clinicaltrials.gov.

OBJECTIVES: To report our experience on the management of superior vena cava graft infection. METHODS: Between 2001 and 2018, patients with superior vena cava synthetic graft or patch reconstruction after resection of intrathoracic tumours or benign disease were selected retrospectively from the French EPITHOR database and participating thoracic centres. Our study population includes patients with superior vena cava graft infection, defined according to the MAGIC consensus. Superior vena cava synthetic grafts in an empyema or mediastinitis were considered as infected. RESULTS: Of 111 eligible patients, superior vena cava graft infection occurred in 12 (11.9%) patients with a polytetrafluoroethylene graft secondary to contiguous contamination. Management consisted of either conservative treatment with chest tube drainage and antibiotics (n = 3) or a surgical graft-sparing strategy (n = 9). Recurrence of infection appears in 6 patients. Graft removal was performed in 2 patients among the 5 reoperated patients. The operative mortality rate was 25%. CONCLUSIONS: Superior vena cava graft infection may develop as a surgical site infection secondary to early mediastinitis or empyema. Graft removal is not always mandatory but should be considered in late or recurrent graft infection or in infections caused by aggressive microorganisms (virulent or multidrug resistant bacteria or fungi).

BACKGROUND: SARS-CoV-2 has been responsible for considerable mortality worldwide, owing in particular to pulmonary failures such as ARDS, but also to other visceral failures and secondary infections. Recent progress in the characterization of the immunological mechanisms that result in severe organ injury led to the emergence of two successive hypotheses simultaneously tested here: hyperinflammation with cytokine storm syndrome or dysregulation of protective immunity resulting in immunosuppression and unrestrained viral dissemination. METHODS: In a prospective observational monocentric study of 134 patients, we analysed a panel of plasma inflammatory and anti-inflammatory cytokines and measured monocyte dysregulation via their membrane expression of HLA-DR. We first compared the results of patients with moderate forms hospitalized in an infectious disease unit with those of patients with severe forms hospitalized in an intensive care unit. In the latter group of patients, we then analysed the differences between the surviving and non-surviving groups and between the groups with or without secondary infections. FINDINGS: Higher blood IL-6 levels, lower quantitative expression of HLA-DR on blood monocytes and higher IL-6/mHLA-DR ratios were statistically associated with the risk of severe forms of the disease and among the latter with death and the early onset of secondary infections. INTERPRETATION: The unique immunological profile in patients with severe COVID-19 corresponds to a moderate cytokine inflammation associated with severe monocyte dysregulation. Individuals with major CSS were rare in our cohort of hospitalized patients, especially since the use of corticosteroids, but formed a very severe subgroup of the disease. FUNDING: None.

OBJECTIVES: To document the prevalence of new headaches in patients with Covid-19 infection and the potential association with other neuro-sensorial symptoms (anosmia and ageusia). The persistence of these symptoms 1 month after recovery was also documented. BACKGROUND: Headaches are a very common symptom of viral infections. Surprisingly, early Chinese studies reported a relatively low prevalence (12-15%) of headaches associated with Covid-19. METHODS: All the patients with laboratory-confirmed or chest-CT-confirmed Covid-19 infection, diagnosed between February 27th and April 15th , 2020 in the dedicated laboratory of Clermont-Ferrand University Hospital were followed for 1 month after recovery. RESULTS: A total of 139 consecutive patients (mean [SD] age, 48.5 [15.3] years; 87 women [62.6%]) were interviewed 1 month after disappearance of fever and dyspnea (semi-structured phone interview). Overall, 59.0% (82/139) of people with Covid-19 had mild disease, 36.7% (51/139) had severe disease, and 4.3% (6/139) had critical illness. Eighty-two (59.0%; 95% CI: 50.3 to 67.3) reported new headaches during the acute phase and 3.6% (5/139) had persistent headaches 1 month after fever and dyspnea remission. Anosmia and ageusia were also very common, occurring in 60.4% (84/139) and 58.3% (81/139) of the patients, respectively. These 2 symptoms persisted in 14.4% (20/139) and 11.5% (16/139) of Covid-19 patients 1 month after recovery. Headaches were neither clearly associated with anosmia, nor with ageusia, and were not associated with disease severity (ie, requiring hospitalization or intensive care unit). CONCLUSION: This specific study highlights the high prevalence of new headaches during Covid-19 infection in French patients. Further studies are needed to refine the characterization of patients with Covid-19-associated headaches.

A presença de diabetes mellitus associou-se a maior incidência de suspeita de psicopatologia. Este estudo permitiu concluir que a suspeita e / ou presença de psicopatologia estaba relacionado com a idade avançada, sexo feminino, solteiro, renda econômica baixa, maior tempo em hemodiálise, estar aposentado e portador de diabetes. A ausência esteve relacionada ao maior nível de escolaridade e trabalho remunerado.
Abstract:End-stage renal disease is considered a pandemic worldwide. In Chile 32% of the economic resources in health are destined to its treatment, being the hemodialisys the most common treatment in those patients. This pathology modifies the entire balance of the person, subjecting it to various stressors and causing alterations in the physical, psychological and social behaviors, directly impacting the mental health of patients. The objective of this research was to identify mental health and its relationship with biosociodemographic characteristics in hemodialysis patients, from the Chronic Unit at Hospital Las Higueras, Talcahuano. A descriptive, correlational and transversal quantitative study was carried out. The data was collected through an interview. The instrument used was the Golberg Scale to measure mental health plus biosociodemographic variables. Out of 53 participants, 58.5% presented absence of psychopathology, 26.4% presence and 15.1% suspicion. There were 56.6% men and 44.4% women, 60.3% were un a relationship, 50.9% had medium level formal studies, 83% were pensioned, and the average time on hemodialysis was 94.2 months. It was also found that the presence of diabetes mellitus was associated with a higher incidence of suspected psychopathology. Therefore, this study allowed us to conclude that the suspicion and / or presence of psychopathology was related to advanced age, female gender, low economic income, longer time on hemodialysis, being pensioned and suffering from diabetes. The absence was related to a higher educational level and well paid jobs.
RESUMEN
Transcutaneous bone biopsy (TCB) is the gold standard for taking microbiological specimens in diabetic foot osteomyelitis (DFO), but this technique is not widely used in diabetic foot care centers. We aimed to evaluate the reliability of per-wound bone biopsy (PWB) cultures by comparing them with concomitant TCB cultures obtained through healthy skin. This is a prospective monocentric study including patients seen in consultation for clinical and radiological diabetic foot osteomyelitis with positive probe-bone tests between April 2015 and May 2018. Two bone biopsies were performed on each consenting patient: TCB through a cutaneous incision in healthy skin, and PWB, after careful debridement of the wound. A total of 46 paired cultures were available from 43 eligible patients. Overall, 16 (42%) of the PWB and TCB pairs had identical culture results, but the TCB cultures were sterile in 8 (17%) cases. For 38 paired cultures with positive TCB, the correlation between PWB results and TCB results was 58.4%. PWB revealed all microorganisms found in the transcutaneous specimen in 26/38 samples (68.5%). In patients with DFO, the culture results of specimens taken by per-wound biopsies did not correlate well with those obtained by TCB. PWB should be reserved for cases where the transcutaneous biopsy is sterile or not feasible.

La presente investigación tuvo como objetivo conocer la calidad de vida y los factores relacionados de los pacientes esquizofrénicos que se controlan en los servicios de salud Concepción y Arauco de Chile durante los meses de abril-junio de 2009. Estudio cuantitativo, descriptivo, correlacional de corte transversal. La población incluida en este trabajo comprendió al total de los pacientes esquizofrénicos (40) bajo régimen de corta estadía. El instrumento utilizado fue la variable principal -calidad de vida (CV)-, que se midió a través del cuestionario SF-36, además se incorporaron variables sociodemográficas y de apoyo social, esta última medida a través del cuestionario Duke- UNC-11. Los resuiltados del estudio reflejan aceptable calidad de vida, lo cual puede asociarse con las condiciones socioculturales de la región.
The objective of this study was to identify quality of life and related factors in schizophrenic patients who were being monitored by health-care services in Concepción and Arauca (Chile) during April-June 2009. It is a quantitative, correlational, cross-sectional descriptive study. The population in question included all schizophrenic patients (40) who were subject to a short-term stay. The principal variable-quality of life (QOL) was the instrument used and was measured with the SF-36 questionnaire. Socio-demographic and social support variables were included as well, the latter through application of the Duke-UNC-11 questionnaire. The findings of the study reflect an acceptable quality of life, which may be associated with the socio-cultural conditions in the region.

La calidad de vida relacionada con la salud es un constructo que se está utilizando cada vez con más frecuencia para evaluar las variables relacionadas con la salud desde la perspectiva del individuo. En este trabajo se analizaron las características descriptivas de las escalas resumidas de componentes de salud físico (CSF) y componentes de salud mental (CSM), provenientes del SF-36 V2 en pacientes insuficientes renales crónicos terminales sometidos a tratamiento con hemodiálisis. Se trata de un estudio cuantitativo de corte transversal cuya población estuvo compuesta por los pacientes de la patología antes citada controlados en los centros de diálisis de la Comuna de Concepción, Chile, en el año 2005. La muestra incluyó a 270 pacientes, que corresponden a un 65 por ciento del universo. El instrumento principal utilizado estuvo constituido por el SF-36, para medir la variable principal Calidad de Vida y se agregaron variables sociodemográficas. El instrumento demostró una alta confiabilidad para los componentes de salud física y mental con un alfa de Cronbach de 0,86 para cada uno. En términos generales los instrumentos CSF y CSM provenientes del SF-36 permiten capturar apropiadamente la situación de vida por la que están atravesando las personas, como es el caso de los pacientes nefrópatas en tratamiento con hemodiálisis, que fueron objeto de este estudio.
The quality of life related to health is a construct that is being used with increasing frequency to evaluate the variables related to health from the perspective of the individual. In this study we analyzed the characteristics of the summarized descriptive scales of physical health components (CSF) and mental health components (MSC) from the SF-36 V2 in terminal patients with chronic renal insufficiency treated with hemodialysis. This is a cross sectional quantitative study with a population of patients with the previously quoted pathology controlled in the dialysis facilities in the area of Concepción, Chile in 2005. The sample consisted of 270 patients, which is 65 percent of the universe. The main instrument was the SF-36 for measuring the quality of life main variable. Socio-demographic variables were added. The instrument showed a high reliability for the components of physical and mental health with a Cronbach's alpha of 0.86, for each one. In general terms, the instruments CSF and MSC from the SF-36 properly capture the life conditions that people are experiencing, as is the case with nephropathy patients undergoing hemodialysis treatment, who were the subject of this study.

OBJECTIVES: To evaluate a strategy based on screening and isolation at admission to a department of infectious diseases during an epidemic of vancomycin-resistant Enterococcus (VRE) at the University Hospital of Clermont-Ferrand. METHODS: Systematic screening for VRE by anal swabs began on November 15, 2004. Patients were isolated on admission if (a) they had been hospitalized more than 24 h in an at-risk department of our hospital or (b) they had received a course of wide-spectrum antimicrobial therapy for longer than 48 h in the three months preceding admission. Patients hospitalized in our department were screened weekly if they were treated with wide-spectrum antibiotics, had a urinary catheter left in place for one week, or were neutropenic. RESULTS: Through May 15, 2005, 12 (3.5%) of 341 swabs were found to be positive for VRE: eight were detected on admission and four during hospitalization. In all, 81 patients were isolated on admission. A case-control study confirmed that the criteria for patient isolation were indeed risk factors for VRE. Isolation was well accepted when it was clearly explained. No new case has been detected since March 2005. CONCLUSION: An isolation strategy based on known risk factors for VRE with systematic screening on admission appears to be an effective way to control an outbreak of VRE, perhaps in part because it helps to keep the medical staff alert to this problem. Isolation is well tolerated as long as it is explained clearly.

Estudio descriptivo de corte transversal, cuyo propósito fue conocer las características personales y calidad de vida de pacientes con insuficiencia renal crónica en tratamiento sustitutivo con hemodiálisis . El grupo de estudio estuvo constituido por 90 pacientes de dos centros de diálisis de la ciudad de Concepción, Chile. La calidad de vida se midió a través del cuestionario genérico de salud SF-36. Aproximadamente la mitad de los pacientes tenían entre 45 y 64 años, la distribución por sexo fue prácticamente similar, tres cuartas partes de los sujetos se declararon con pareja , más de la mitad poseía baja escolaridad y todos poseían algún sistema previsional. El valor más alto de calidad de vida fue 81,8 y el más bajo 3,25. Por lo que se pudo concluir que aproximadamente la mitad de las personas encuestadas tenía una calidad de vida por sobre el nivel promedio.
