RESUMO

Solid organ transplant recipients (SOTRs) frequently receive adjunctive glucocorticoid therapy (AGT) for Pneumocystis jirovecii pneumonia (PJP). This multicenter cohort of SOTRs with PJP admitted to 20 transplant centers in Canada, the United States, Europe, and Australia, was examined for whether AGT was associated with a lower rate of all-cause intensive care unit (ICU) admission, 90-day death, or a composite outcome (ICU admission or death). Of 172 SOTRs with PJP (median [IQR] age: 60 (51.5-67.0) years; 58 female [33.7%]), the ICU admission and death rates were 43.4%, and 20.8%, respectively. AGT was not associated with a reduced risk of ICU admission (adjusted odds ratio [aOR] [95% CI]: 0.49 [0.21-1.12]), death (aOR [95% CI]: 0.80 [0.30-2.17]), or the composite outcome (aOR [95% CI]: 0.97 [0.71-1.31]) in the propensity score-adjusted analysis. AGT was not significantly associated with at least 1 unit of the respiratory portion of the Sequential Organ Failure Assessment score improvement by day 5 (12/37 [32.4%] vs 39/111 [35.1%]; P = .78). We did not observe significant associations between AGT and ICU admission or death in SOTRs with PJP. Our findings should prompt a reevaluation of routine AGT administration in posttransplant PJP treatment and highlight the need for interventional studies.

RESUMO

BACKGROUND: Previous studies showed HIV-negative immunocompromised patients are susceptible to Pneumocystis pneumonia (PCP). However, the PCP outcome has not been compared among HIV-negative immunocompromised patients. METHODS: In this retrospective cohort study at the University Health Network, we included all HIV-negative immunocompromised patients who fulfilled the European Organization for Research and Treatment of Cancer (EORTC) PCP diagnosis criteria from December 2018 to December 2019. We compared the demographics, comorbidities, course of illness, and PCP outcome (28-day mortality and composite outcome [i.e., death or intensive care unit (ICU) admission]) between solid organ transplant (SOT) and non-SOT patients. RESULTS: Of 160 non-HIV patients with PCP diagnoses, 118 patients fulfilled EORTC criteria (76 males [64.4%], median [range] age: 65.5 [21-87] years). PCP presentation in SOT recipients (n = 14) was more severe than non-SOT patients (n = 104): acute presentation (onset <7 days before admission: 11/14 [78.6%] vs. 51/104 [56%], p = .037), shortness of breath (100% vs. 75/104 [74.3%], p = .037), median [range] O2 saturation (88% [75%, 99%] vs. 92%[70%, 99%], p = .040), and supplemental O2 requirement (12/14 [85.7%] vs. 59/104 [56.7%], p = .044). The mortality [4/14, (28.6%) vs. 15/104 (14.4%), p = .176], ICU admission (10/14 [71.4%] vs. 18/104 [17.3%], p < .0001), and mechanical ventilation (8/14 [57.1%] vs. 18/104 [17.3%], p = .0007) in SOT patients was different from non-SOT patients. In multivariable analysis, SOT recipients were at greater risk of composite outcome than non-SOT patients (aOR [CI95%]: 12.25 [3.08-48.62], p < .001). CONCLUSION: PCP presentation and outcomes in SOT recipients are more severe than in non-SOT patients. Further studies are required to explore the biological reasons for this difference.

RESUMO

BACKGROUND: The natural history of candidemia in kidney transplant recipients (KTR) remains poorly understood. This study aimed to evaluate mortality, prognostic factors and overall graft loss after candidemia in KTRs. METHODS: This is a retrospective multicentre study enrolling all KTRs ≥15 years old with candidemia diagnosed at hospitals in Brazil, Spain and Italy from 2010 to 2020. Primary endpoints were mortality rates at 14 and 30 days. Secondary endpoints were prognostic factors of 14-day mortality and overall graft loss. RESULTS: We enrolled 93 KTRs of which 75 were from Brazil. The mean time interval from transplantation to the onset of candidemia was 45.2 ± 61.5 months. 42% of all patients were on haemodialysis, 31.3% had an episode of sepsis and 39% underwent surgery within 30 days before fungemia. European patients were more likely to receive echinocandin (32 vs. 72%, p < .001). 22.7% of Brazilian patients did not receive any antifungal before death. All-cause mortality at 14 days was higher in Brazil (41.3 vs. 11.1%, p = .016). Candida colonisation (OR 6.91 [95% CI: 1.08-44.3], p = .042) and hypotension (OR 4.87 [95% CI: 1.62-14.66], p = .005) were associated with 14-day mortality. Echinocandin treatment had a protective effect (OR 0.19 [95% CI: 0.05-0.73], p = .015). Graft loss at 90 days occurred in 48% of patients (70.7 in Brazil vs. 22.2% in Europe, p < .01). CONCLUSIONS: Candidemia in KTR is usually documented late after engraftment in patients requiring HD, surgical procedures and dysbiosis secondary to antibiotic use. Mortality was higher in Brazil. Echinocandin therapy was associated with improved survival.

RESUMO

Current guidelines recommend against systematic screening or treating asymptomatic bacteriuria (AB) among kidney transplant (KT) recipients, although the evidence regarding episodes occurring early after transplantation or in the presence of anatomical abnormalities is inconclusive. Oral fosfomycin may constitute a good option for the treatment of post-transplant AB, particularly due to the emergence of multidrug-resistant (MDR) uropathogens. Available clinical evidence supporting its use in this specific setting, however, remains scarce. We performed a retrospective study in 14 Spanish institutions from January 2005 to December 2017. Overall, 137 episodes of AB diagnosed in 133 KT recipients treated with oral fosfomycin (calcium and trometamol salts) with a test-of-cure urine culture within the first 30 days were included. Median time from transplantation to diagnosis was 3.1 months (interquartile range [IQR]: 1.1 - 10.5). Most episodes (96.4% [132/137]) were caused by gram-negative bacteria (GNB), and 56.9% (78/137) were categorized as MDR (extended-spectrum ß-lactamase-producing Enterobacterales [20.4%] and carbapenem-resistant GNB [2.9%]). Rate of microbiological failure at month 1 was 40.1% (95% confidence interval [95%CI]: 31.9 - 48.9) for the whole cohort and 42.3% (95%CI: 31.2 - 54.0) for episodes due to MDR pathogens. Previous urinary tract infection (odds ratio [OR]: 2.42; 95%CI: 1.11 - 5.29; P-value = 0.027) and use of fosfomycin as salvage therapy (OR: 8.31; 95%CI: 1.67 - 41.35; P-value = 0.010) were predictors of microbiological failure. No severe treatment-related adverse event were detected. Oral fosfomycin appears to be a suitable and safe alternative for the treatment (if indicated) of AB after KT, including those episodes due to MDR uropathogens.

RESUMO

ABSTRACT: Over time, a complex crossroad between disordered eating behaviors (DEBs) and borderline personality features (BPFs) and their association with childhood emotional and physical maltreatment have been established. The present study aimed at evaluating the direct and indirect effect of physical and emotional abuse and neglect on DEB via BPF in a nonclinical adolescent sample. A total of 786 adolescents (48.3% male; mean age, 16.25 years; SD, 1.76) participated in the study. The mediation model suggested the pivotal predictive role of emotional maltreatment compared with the physical one. Indeed, both emotional abuse and neglect directly and indirectly predicted disordered eating via BPF ( ß = 0.097; p < 0.001 and ß = 0.042; p < 0.01, respectively). Likely, the emotional maltreatment represents the beginning of a developmental cascade that culminates in DEB as a maladaptive coping strategy in response to negative emotions, through BPF. On the contrary, physical maltreatment seems to be less involved in the developmental cascade.

RESUMO

BACKGROUND: The diagnosis of invasive aspergillosis (IA) can be problematic in solid organ transplantation (SOT). The prognosis greatly varies according to the type of transplant, and the impact of prophylaxis is not well defined. PATIENTS AND METHODS: The Diaspersot cohort analyses the impact of IA in SOT in Spain during the last 10 years. Proven and probable/putative IA was included. RESULTS: We analysed 126 cases of IA. The incidences of IA were as follows: 6.5%, 2.9%, 1.8% and 0.6% for lung, heart, liver and kidney transplantation, respectively. EORTC/MSG criteria confirmed only 49.7% of episodes. Tree-in-bud sign or ground-glass infiltrates were present in 56.3% of patients, while serum galactomannan (optical density index >0.5) was positive in 50.6%. A total of 41.3% received combined antifungal therapy. Overall mortality at 3 months was significantly lower (p < 0.001) in lung transplant recipients (14.8%) than in all other transplants [globally: 48.6%; kidney 52.0%, liver 58.3%, heart 31.2%, and combined 42.9%]. Fifty-four percent of episodes occurred despite the receipt of antifungal prophylaxis, and in 10%, IA occurred during prophylaxis (breakthrough infection), with both nebulised amphotericin (in lung transplant recipients) and candins (in the rest). CONCLUSIONS: Invasive aspergillosis diagnostic criteria, applied to SOT patients, may differ from those established for haematological patients. IA in lung transplants has a higher incidence, but is associated with a better prognosis than other transplants. Combination therapy is frequently used for IA in SOT. Prophylactic measures require optimisation of its use within this population.

RESUMO

Oral fosfomycin may constitute an alternative for the treatment of lower urinary tract infections (UTIs) in kidney transplant recipients (KTRs), particularly in view of recent safety concerns with fluroquinolones. Specific data on the efficacy and safety of fosfomycin in KTR are scarce. We performed a retrospective study in 14 Spanish hospitals including KTRs treated with oral fosfomycin (calcium and trometamol salts) for posttransplant cystitis between January 2005 and December 2017. A total of 133 KTRs developed 143 episodes of cystitis. Most episodes (131 [91.6%]) were produced by gram-negative bacilli (GNB), and 78 (54.5%) were categorized as multidrug resistant (including extended-spectrum ß-lactamase-producing Enterobacteriaceae [14%] or carbapenem-resistant GNB [3.5%]). A median daily dose of 1.5 g of fosfomycin (interquartile range [IQR]: 1.5-2) was administered for a median of 7 days (IQR: 3-10). Clinical cure (remission of UTI-attributable symptoms at the end of therapy) was achieved in 83.9% (120/143) episodes. Among those episodes with follow-up urine culture, microbiological cure at month 1 was achieved in 70.2% (59/84) episodes. Percutaneous nephrostomy was associated with a lower probability of clinical cure (adjusted odds ratio: 10.50; 95% confidence interval: 0.98-112.29; P = 0.052). In conclusion, fosfomycin is an effective orally available alternative for treating cystitis among KTRs.

RESUMO

BACKGROUND: Candidaemia is a leading cause of bloodstream infections in hospitalized patients all over the world. It remains associated with high mortality. OBJECTIVES: To assess the impact of implementing an evidence-based package of measures (bundle) on the quality of care and outcomes of candidaemia. METHODS: A systematic review of the literature was performed to identify measures related to better outcomes in candidaemia. Eight quality-of-care indicators (QCIs) were identified and a set of written recommendations (early treatment, echinocandins in septic shock, source control, follow-up blood culture, ophthalmoscopy, echocardiography, de-escalation, length of treatment) was prospectively implemented. The study was performed in 11 tertiary hospitals in Spain. A quasi-experimental design before and during bundle implementation (September 2016 to February 2018) was used. For the pre-intervention period, data from the prospective national surveillance were used (May 2010 to April 2011). RESULTS: A total of 385 and 263 episodes were included in the pre-intervention and intervention groups, respectively. Adherence to all QCIs improved in the intervention group. The intervention group had a decrease in early (OR 0.46; 95% CI 0.23-0.89; P = 0.022) and overall (OR 0.61; 95% CI 0.4-0.94; P = 0.023) mortality after controlling for potential confounders. CONCLUSIONS: Implementing a structured, evidence-based intervention bundle significantly improved patient care and early and overall mortality in patients with candidaemia. Institutions should embrace this objective strategy and use the bundle as a means to measure high-quality medical care of patients.

RESUMO

BACKGROUND: Almost one third of the patients with candidemia develop septic shock. The understanding why some patients do and others do not develop septic shock is very limited. The objective of this study was to identify variables associated with septic shock development in a large population of patients with candidemia. METHODS: A post hoc analysis was performed on two prospective, multicenter cohort of patients with candidemia from 12 hospitals in Spain and Italy. All episodes occurring from September 2016 to February 2018 were analyzed to assess variables associated with septic shock development defined according to The Third International Consensus Definition for Sepsis and Septic Shock (Sepsis-3). RESULTS: Of 317 candidemic patients, 99 (31.2%) presented septic shock attributable to candidemia. Multivariate logistic regression analysis identifies the following factors associated with septic shock development: age > 50 years (OR 2.57, 95% CI 1.03-6.41, p = 0.04), abdominal source of the infection (OR 2.18, 95% CI 1.04-4.55, p = 0.04), and admission to a general ward at the time of candidemia onset (OR 0.21, 95% CI, 0.12-0.44, p = 0.001). Septic shock development was independently associated with a greater risk of 30-day mortality (OR 2.14, 95% CI 1.08-4.24, p = 0.02). CONCLUSIONS: Age and abdominal source of the infection are the most important factors significantly associated with the development of septic shock in patients with candidemia. Our findings suggest that host factors and source of the infection may be more important for development of septic shock than intrinsic virulence factors of organisms.

RESUMO

BACKGROUND: Despite being considered a high-risk population for invasive fungal disease, specific features of candidemia among solid organ transplant (SOT) recipients remain poorly characterized. METHODS: We compiled prospective data from two multicenter studies on candidemia performed over two consecutive periods in Spain: the CANDIPOP Study (2010-2011) and the CANDI-Bundle Study (2016-2018). Episodes diagnosed in adult SOT recipients in 10 participating centers were included. Risk factors for clinical failure (all-cause 7-day mortality and/or persistent candidemia for ≥72 hours) and 30-day mortality were investigated by univariate analysis. RESULTS: We included 55 episodes of post-transplant candidemia (32 and 23 of which occurred during the first and second periods). Kidney (38.2%) and liver recipients (30.9%) were the most common populations. Candida albicans accounted for 27.3% of episodes. The proportion of C glabrata increased over time (18.8% vs 30.4% for the first and second periods). There were no differences in the rate of fluconazole non-susceptible isolates (50.0% vs 60.0%, respectively). Clinical failure and 30-day mortality occurred in 25.5% and 27.3% of episodes and were associated with the severity of candidemia (Pitt score and severe sepsis/septic shock). Kidney transplantation (unadjusted odds ratio [uOR]: 0.17; 95% confidence interval [CI]: 0.03-0.85; P-value = .020), early catheter removal (uOR: 0.15; 95% CI: 0.03-0.76; P-value = .013), and appropriate early antifungal therapy (uOR: 0.14; 95% CI: 0.02-0.89; P-value = .041) were protective for 30-day mortality. CONCLUSIONS: High rates of non-albicans species and fluconazole non-susceptibility must be taken into account to optimize therapeutic management and outcomes in SOT recipients with candidemia.

RESUMO

BACKGROUND: Posaconazole (PCZ) is used mainly for the prevention of invasive fungal infection (IFI). METHODS: A multicentre retrospective, investigational study using a non-randomized, single-arm design carried out in six tertiary hospitals in Spain to evaluate the use of PCZ in different forms of administration in the (non-prophylactic) treatment of IFI. RESULTS: Over an eight-year-period, 67 patients were included in this study. PCZ was administered as salvage therapy (intolerant or refractory to a previous antifungal agent) in 65/67 (97%); of these, it was used against Aspergillosis (68.6%), Zygomycosis (13.4%), other moulds (8.9%) and yeast (10.5%). The median duration of PCZ therapy was 75 days. The oral solution was associated with low serum levels (<0.7 mg/L) in 63% of available patients. Clinical response at 3 and 12 months of PCZ therapy were for aspergillosis: 47.8% and 41.3%; for zygomycosis: 55.5% and 55.5%; and for other mycoses: 69.2% and 69.2%, respectively. Suspension by toxicity was only observed in 6% and 7.5% of patients at 3 and 12 months, respectively, mainly with grade III/IV elevations of liver function test (LFTs). CONCLUSIONS: Posaconazole salvage therapy, especially oral tablets, can be an effective alternative option for patients with IFI who cannot tolerate or do not respond to other antifungal therapies.

RESUMO

Objectives: We assessed the potential role of T2Candida MR (T2MR) and serological biomarkers [ß-d-glucan (BDG) or Candida albicans germ tube antibodies (CAGTA)], alone or in combination with standard cultures, for identifying patients with suspected invasive candidiasis (IC), who may benefit from maintaining antifungal therapy. Methods: Prospective observational multicentre study including all adult patients receiving empirical antifungal therapy for suspected IC, from January to June 2017. CAGTA, BDG and T2MR were determined at baseline and at +2 and +4 days after enrolment. Primary endpoint was the diagnostic value of CAGTA, BDG and T2MR, alone or in combination with standard culture, to predict diagnosis of IC and/or mortality in the first 7 days after starting antifungal therapy (poor outcome). Results: Overall, 14/49 patients (28.6%) had a poor outcome (7 died within the first 7 days of antifungal therapy, whereas 7 ended with a diagnosis of IC). CAGTA [3/14 (21.4%) versus 8/35 (22.9%), P = 1] and BDG [8/14 (57.1%) versus 17/35 (48.6%), P = 0.75] results were similar in poor- and good-outcome patients. Conversely, a positive T2MR was associated with a higher risk of poor outcome [5/14 (35.7%) versus 0/35 (0.0%) P = 0.0001]. Specificity and positive predictive value of a positive T2MR for predicting poor outcome were both 100%, with a negative predictive value of 79.6%. After testing the combinations of biomarkers/standard cultures and T2MR/standard cultures, the combination of T2MR/standard cultures showed a high capacity to discriminate patients with poor outcome from those with good clinical evolution. Conclusions: T2MR may be of significant utility to identify patients who may benefit from maintaining antifungal therapy.

RESUMO

Objectives: Diagnosis of complicated candidaemia represents a challenge for clinicians since early clinical manifestations may be non-specific and difficult to identify, thus precluding an appropriate treatment. Patients and methods: This was a multicentre prospective study for predicting complicated episodes in patients with bloodstream infection caused by Candida species, while assessing the value of follow-up blood cultures (BCs) and the persistence of positive results for T2Candida MR (T2MR) and blood ß-d-glucan (BDG) tests. Immediately after the first positive BC yielding Candida species, samples were obtained on days 0, +2, +4, +7 and +14, to simultaneously perform follow-up BC, T2MR and BDG. An episode of candidaemia was defined as 'complicated' when (i) it caused septic metastasis; and/or (ii) it was the cause of the patient's death. Results: From January to June 2017, 30 patients were enrolled in the study. Of these, nine (30%) had complicated candidaemia. Values of persistently positive samples for the prediction of complicated episodes for BCs, T2MR and BDG, respectively, were as follows: sensitivity (44.4%, 100%, 100%); specificity (76.1%, 76.1%, 38.9%); positive predictive value (PPV) (44.4%, 64.2%, 40.9%) and negative predictive value (NPV) (76.1%, 100%, 100%). In multivariate analysis, having a positive T2MR within the first 5 days was associated with an almost 37-fold higher risk of developing complicated candidaemia. Conclusions: The T2MR test performed in patients with proven candidaemia may be a better marker of complicated infection than follow-up BCs or BDG. It is possible that this test may change current clinical practice, influencing the length and type of antifungal therapy in this population.

Problematic social media use (PSMU) can have profound and detrimental effects across various domains of life. As a result, scientific investigations into the risk factors associated with this phenomenon can hold substantial practical implications within the clinical and preventive realms. Consistently with this framework, this study aimed to examine the relationship between certain variables and PSMU, with a specific focus on alexithymia, defense mechanisms, and fear of missing out (FoMO). A sample of 340 young adults (Mage = 26.42 years; SD = 3.689) completed an online survey, including the Bergen Social Media Addiction Scale, FoMO scale, 40-Item Defense Style Questionnaire, and 20-Item Toronto Alexithymia Scale. Results showed a statistically significant mixed serial-parallel mediation model. A significant total effect in the association between alexithymia and FoMO emerged. Furthermore, defense mechanisms and FoMO significantly and totally mediated this relationship. These findings have the potential to provide valuable insights in the field of clinical research on PSMU, and can offer practical information for enhancing clinical practice.

RESUMO

BACKGROUND: COVID-19-associated pulmonary aspergillosis (CAPA) has been reported to be an emerging and potentially fatal complication of severe COVID-19. However, risk factors for CAPA have not been systematically addressed to date. METHODS: In this systematic review and meta-analysis to identify factors associated with CAPA, we comprehensively searched five medical databases: Ovid MEDLINE; Ovid Embase; the Cochrane Database of Systematic Reviews; the Cochrane Central Register of Controlled Trials; and the WHO COVID-19 Database. All case-control and cohort studies in adults (aged >18 years) that described at least six cases of CAPA and evaluated any risk factors for CAPA, published from Dec 1, 2019, to July 27, 2023, were screened and assessed for inclusion. Only studies with a control population of COVID-19-positive individuals without aspergillosis were included. Two reviewers independently screened search results and extracted outcome data as summary estimates from eligible studies. The primary outcome was to identify the factors associated with CAPA. Meta-analysis was done with random-effects models, with use of the Mantel-Haenszel method to assess dichotomous outcomes as potential risk factors, or the inverse variance method to assess continuous variables for potential association with CAPA. Publication bias was assessed with funnel plots for factors associated with CAPA. The study is registered with PROSPERO, CRD42022334405. FINDINGS: Of 3561 records identified, 27 articles were included in the meta-analysis. 6848 patients with COVID-19 were included, of whom 1324 (19·3%) were diagnosed with CAPA. Diagnosis rates of CAPA ranged from 2·5% (14 of 566 patients) to 47·2% (58 of 123). We identified eight risk factors for CAPA. These factors included pre-existing comorbidities of chronic liver disease (odds ratio [OR] 2·70 [95% CI 1·21-6·04], p=0·02; I2=53%), haematological malignancies (OR 2·47 [1·27-4·83], p=0·008; I2=50%), chronic obstructive pulmonary disease (OR 2·00 [1·42-2·83], p<0·0001; I2=26%), and cerebrovascular disease (OR 1·31 [1·01-1·71], p=0·05; I2=46%). Use of invasive mechanical ventilation (OR 2·83; 95% CI 1·88-4·24; p<0·0001; I2=69%), use of renal replacement therapy (OR 2·26 [1·76-2·90], p<0·0001; I2=14%), treatment of COVID-19 with interleukin-6 inhibitors (OR 2·88 [1·52-5·43], p=0·001; I2=89%), and treatment of COVID-19 with corticosteroids (OR 1·88 [1·28-2·77], p=0·001; I2=66%) were also associated with CAPA. Patients with CAPA were typically older than those without CAPA (mean age 66·6 years [SD 3·6] vs 63·5 years [5·3]; mean difference 2·90 [1·48-4·33], p<0·0001; I2=86%). The duration of mechanical ventilation in patients with CAPA was longer than in those without CAPA (n=7 studies; mean duration 19·3 days [8·9] vs 13·5 days [6·8]; mean difference 5·53 days [1·30-9·77], p=0·01; I2=88%). In post-hoc analysis, patients with CAPA had higher all-cause mortality than those without CAPA (n=20 studies; OR 2·65 [2·04-3·45], p<0·0001; I2=51%). INTERPRETATION: The identified risk factors for CAPA could eventually be addressed with targeted antifungal prophylaxis in patients with severe COVID-19. FUNDING: None.

RESUMO

OBJECTIVES: Carbapenemase-mediated carbapenem resistance in Pseudomonas aeruginosa is a relevant health problem. We detected for the first time in Spain two clinical NDM-producing P. aeruginosa (NDM-Pa) isolates in two Ukrainian patients admitted to our hospital between April and August 2022. METHODS: Antimicrobial susceptibility was studied by microdilution and MIC gradient strips (EUCAST-2022 criteria). Carbapenemase genes were detected by the Xpert Carba-R and immunochromatography assays. WGS (Illumina and Oxford-Nanopore) was also performed. RESULTS: In May 2022, we detected an NDM-Pa in a sternotomy wound in a patient. In June-2022, a second NDM-Pa along with an OXA-48-Klebsiella pneumoniae (OXA-48-Kp) isolate was detected in a mandibular abscess from an unrelated patient. Moreover, an NDM+OXA-48-K. pneumoniae (NDM+OXA-48-Kp) was also found in a rectal sample of this patient. Both patients had undergone surgery in Ukraine before their transfer to our hospital. NDM-Pa isolates were resistant to all tested antimicrobials with the exception of aztreonam (MIC = 8 mg/L), colistin (MIC =2 mg/L) and cefiderocol (MIC range = 0.75-2 mg/L). WGS confirmed that both P. aeruginosa isolates were NDM-1 producers, belonged to ST773 and shared an identical resistome. blaNDM-1 was located on a ∼117-Kb chromosomally integrated integrative conjugative element (ICE). OXA-48-Kp and NDM+OXA-48-Kp belonged to ST147 and contained blaOXA-48 on an identical ∼300-Kb IncHIB-plasmid. blaNDM-1 was located on a 51-Kb IncFIB-plasmid only found in NDM+OXA-48-Kp. CONCLUSIONS: This is the first description of NDM-Pa in Spain. We highlight the threat of further cross-border dissemination of NDM-1 through P. aeruginosa along with K. pneumoniae high-risk clones also carrying OXA-48, which draws a complex epidemiological scenario.

RESUMO

Although nebulized liposomal amphotericin B (NLAB) is being used in invasive pulmonary aspergillosis (IPA) prophylaxis, no clinical trial has shown its efficacy as a therapeutic strategy. NAIFI is the inaugural randomized, controlled clinical trial designed to examine the safety and effectiveness of NLAB (dosage: 25 mg in 6 mL, three times per week for 6 weeks) against a placebo, in the auxiliary treatment of IPA. Throughout the three-year clinical trial, thirteen patients (six NLAB, seven placebo) were included, with 61% being onco-hematological with less than 100 neutrophils/µL. There were no significant differences noted in their pre- and post-nebulization results of forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and oxygen saturation between the groups. Neither bronchospasm nor serum amphotericin B levels were reported in any patients given NLAB. 18F-Fluorodeoxyglucose positron emission tomography (FDG-PET-TC) was carried out at the baseline and after 6 weeks. A notable decrease in median SUV (standardized uptake value) was observed in NLAB patients after 6 weeks (-3.6 vs. -0.95, p: 0.039, one tail). Furthermore, a reduction in serum substance galactomannan and beta-D-Glucan was identified within NLAB recipients. NLAB is well tolerated and safe for patients with IPA. Encouraging indirect efficacy data have been derived from image monitoring or biomarkers. However, further studies involving more patients are necessary.

RESUMO

BACKGROUND: Isavuconazole (ISA) and voriconazole (VORI) are recommended as the first-line treatment for invasive aspergillosis (IA). Despite theoretical advantages of ISA, both triazole agents have not been compared in solid organ transplant recipients. METHODS: We performed a post hoc analysis of 2 retrospective multicenter cohorts of solid organ transplant recipients with invasive fungal disease (the SOTIS [Solid Organ Transplantation and ISavuconazole] and DiasperSOT [DIagnosis of ASPERgillosis in Solid Organ Transplantation] studies). We selected adult patients with proven/probable IA that were treated for ≥48 h with ISA (n = 57) or VORI (n = 77) as first-line therapy, either in monotherapy or combination regimen. The primary outcome was the rate of clinical response at 12 wk from the initiation of therapy. Secondary outcomes comprised 12-wk all-cause and IA-attributable mortality and the rates of treatment-emergent adverse events and premature treatment discontinuation. RESULTS: Both groups were comparable in their demographics and major clinical and treatment-related variables. There were no differences in the rate of 12-wk clinical response between the ISA and VORI groups (59.6% versus 59.7%, respectively; odds ratio [OR], 0.99; 95% confidence interval [CI], 0.49-2.00). This result was confirmed after propensity score adjustment (OR, 0.81; 95% CI, 0.32-2.05) and matching (OR, 0.79; 95% CI, 0.31-2.04). All-cause and IA-attributable mortality were also similar. Patients in the ISA group were less likely to experience treatment-emergent adverse events (17.5% versus 37.7%; P = 0.011) and premature treatment discontinuation (8.8% versus 23.4%; P = 0.027). CONCLUSIONS: Front-line treatment with ISA for posttransplant IA led to similar clinical outcomes than VORI, with better tolerability and higher treatment completion.

RESUMO

INTRODUCTION: Digital screen media use has significantly grown in all age groups and at an increasingly young age, including toddlers, schoolers, and primary school children. Although there is evidence that excessive early childhood media exposure can lead to several negative developmental outcomes, no systematic review on Problematic Media Use (PMU) of children under 10 years old have been provided. The aim of the present systematic review was to identify (i) the main instruments used to measure children's PMU across different studies; (ii) the risk and protective factors which might increase or reduce children's PMU; and (iii) the negative outcomes associated with children's PMU. METHODS: This study was conducted following the systematic review guidelines proposed in the PRISMA statement. A total of 35 studies published between 2012-2022 and with a mean sample age between 0 and 10 years old were ultimately included in this literature review. RESULTS: Use of media for more than 2 h a day, male gender, and higher age increased the risk of developing PMU among children. PMU led to several negative consequences for children's development and well-being (e.g., more problematic behaviors, sleep problems, higher depressive symptoms, lower emotional intelligence, and lower academic achievements). Children who experienced negative psychological symptoms, a dysfunctional parent-child relationship, and difficulties in school context were more prone to develop PMU. However, an authoritative parenting style and restrictive parental mediation reduced the risk of developing PMU among children. Finally, self-report measures specifically designed to get the younger children's perspective are still few and not so widely used. CONCLUSIONS: Overall, this research field is still in its infancy and needs further investigation. Likely, a dysfunctional family system can lead children to experience emotional distress and negative psychological symptoms, which they try to manage by escaping into the virtual world, thus increasing the risk of developing PMU. As the children's PMU is closely affected by the family environment, future prevention interventions should target both children and their parents to improve their self-regulatory and mentalizing capabilities, as well as parental mediation strategies and general parenting practices.

RESUMO

Objective: Endometriosis is a pathological condition characterized by endometrial-like tissue outside the uterus, chronic inflammatory reaction, and pelvic pain that dramatically decrease women's health-related quality of life (HRQoL). Furthermore, this invisible and difficultly diagnosable disease might lead women to experience alexithymia, loneliness, and consequent impairment of perceived quality of life. Firstly, the present study aimed at validating the Italian EHP-30 version which is the most used specific questionnaire for HRQoL measurement. Secondly, the present study aimed at exploring the still understudied relationship between alexithymia and HRQoL in endometriosis conditions, evaluating the mediating role of perceived loneliness. Method: A total of 435 women with endometriosis (mean age=35.75 years) have been involved. All items were loaded on their own factors. Results: The measure showed good internal consistency (Cronbach's α ranged between 0.60-0.95 for core and 0.74-0.94 for modular parts). The Italian EHP-30 is a psychometrically valid measure of HRQoL with endometriosis. The tested mediation model provided adequate goodness-of-fit indices (χ2 (51) = 206.071; p < 0.001; RMSEA = 0.084; 90%CI: 0.072, 0.096, CFI = .933, SRMR= 0.058), showing that alexithymia only indirectly affected women's perceived HRQoL, via the mediating effect of feelings of loneliness. Conclusions: The current study highlighted the pivotal role of perceived loneliness in directly affecting women's quality of life and mediating the effect of the alexithymic experiences.
