Background: The diagnosis of pulmonary embolism (PE) is based on the application of a priori probability scales such as the Wells scale or PERC. However, the clinical heterogeneity of this pathology results in the absence of a target population to apply these algorithms. The Wells score does consider the possibility of an alternative diagnosis, awarding an additional point if no other diagnosis is likely, yet the presence of objective alternative diagnoses can still complicate clinical assessment and lead to unnecessary testing or missed diagnoses. Objective: The aim of this study is to evaluate the discrimination capacity of clinical objective factors with a high negative predictive value for PE, compared to PERC in terms of reducing unnecessary testing across different risk strata of the Wells scale. Materials and Methods: This was a single-center retrospective cohort study, including patients who underwent chest CT angiography to rule out PE at a university hospital between 2008 and 2017, considering the presence of PE as the study outcome. The study collected demographic data, comorbidities, and clinical presentation data. The presence of objective criteria for pneumonia, heart failure, exacerbation of COPD, or the use of anticoagulation in non-oncological patients were considered a priori criteria with a high negative predictive value. Results: The analyses were performed on a cohort of 399 patients with an average age of 65 years and 53% females. A total of 139 patients were diagnosed with PE by CT angiography. The presence of factors with a high NPV showed a sensitivity of 100% in low-risk patients according to Wells, with sensitivity dropping below 50% in other populations. The association of these factors in the PERC plus criteria would allow a reduction of up to 34% in CT angiographies in patients with low risk according to the Wells scale. Conclusions: The combination of risk stratification of the Wells scale and PERC plus criteria allows an absolute reduction of 34.3% in the performance of CT angiographies in patients classified as low risk with a sensitivity and a negative predictive value of 100%. The preexistence of an alternative diagnosis does not allow ruling out PE in patients with intermediate or high risk according to the Wells scale. Full article

Background: The multisystem manifestations of Fabry disease can create major challenges in patient care. Although enzyme replacement therapy with recombinant agalsidase beta has demonstrated clinical benefits, the standard fortnightly, multi-hour infusion regimen imposes a substantial burden on patients. Methods: We assessed the safety and feasibility of shortening the agalsidase beta infusion time to 90 min in adult patients with classic or later-onset Fabry disease in the absence of premedication. A total of 39 consecutive adult patients (agalsidase-naïve: n = 7; with significant comorbidities: n = 15) with no recent infusion-associated reactions underwent a total of 85 agalsidase beta infusions in our tertiary reference centre for lysosomal diseases. Each infusion was administered at a constant rate (between 0.78 and 1.17 mg/min, depending on the total dose administered). Results: No adverse events of any type (including discomfort and infusion-associated reactions) were reported during or after infusions. The patients’ vital signs and physical examination remained stable, and patients’ satisfaction was high. Conclusions: Our results suggest that shortening the agalsidase beta infusion time to 90 min is safe and feasible in stably treated adult patients with Fabry disease and no recent infusion-associated reactions.

Background: Eosinophilic esophagitis (EoE) is a rare, chronic immune-mediated disorder with limited treatment options. Despite the U.S. Food and Drug Administration (FDA) approval of dupilumab for EoE, other monoclonal antibodies remain unapproved and are used off-label with limited evidence on their efficacy and safety. This systematic review rigorously and comprehensively evaluates the evidence for monoclonal antibody therapies used off-label to treat EoE. Methods: We conducted a systematic review across PubMed, EMBASE, Cochrane Central, and ClinicalTrials.gov, assessing the efficacy and safety of off-label monoclonal antibodies in EoE through clinical outcomes and the FDA Adverse Event Reporting System (FAERS) data. Results: Among ten monoclonal antibodies reviewed, mepolizumab that targets IL-5 showed the most promise with a moderate recommendation based on Level 2 evidence. Others like omalizumab (anti-IgE), dectrekumab (anti-IL-13), and reslizumab (anti-IL-5) showed limited utility. Safety evaluations via the FAERS database revealed significant adverse drug reactions, including serious events like asthmatic crises, pneumonia, and adrenal insufficiency for mepolizumab and reslizumab, as well as chronic obstructive pulmonary disease and gastroenteritis for omalizumab. Dectrekumab’s safety profile remains unclear due to a lack of data. Conclusions: While mepolizumab demonstrates potential as an off-label treatment, none of the antibodies reviewed have FDA approval for EoE. Clinicians should consider the balance between local and systemic effects and exercise caution, closely monitoring for adverse effects, particularly in patients with respiratory comorbidities. Continued research is crucial to establish a more robust evidence base for these therapies. Full article

Patients with interstitial lung diseases (ILDs) associate a large variety of comorbidities that have a significant impact on their clinical outcomes and survival. Among these comorbidities is neurological impairment. This review highlights what is known about the cognitive function, central nervous system (CNS), depression, and anxiety in patients with specific forms of fibrosing ILDs, such as idiopathic pulmonary fibrosis, sarcoidosis, hypersensitivity pneumonitis, connective tissue diseases, etc. The most common pathogenic mechanisms for neurocognitive dysfunction as well as the screening methods and tools for their identification are also described in this review.

Background/Objectives: Acetabular erosion is a postoperative condition that can occur after hip hemiarthroplasty (HA), potentially leading to pain and requiring conversion to total hip arthroplasty (THA). Given the discrepancy in its incidence and impact in the literature, this study aims to report the incidence of symptomatic acetabular erosion and the subsequent conversion to THA in all HA cases performed in a single health system. Methods: A total of 2477 HA cases had their clinical notes and serial radiographs examined for this retrospective study. Outcome measures included any records of hip or groin pain and conversion to THA that were attributed to acetabular erosion as documented in the clinical notes. Results: Two thousand four hundred and seventy-seven HA cases were reviewed in this study. The mean age for all patients in the study was 81.5 years and the mean follow up was 3.7 years. Out of the 2477 HA cases, only 12 HA cases (0.48%) in 12 patients had data records of chronic hip pain, attributable to acetabular wear in the clinical notes, of variable severity and presentations. The mean duration until the clinical documentation of acetabular wear-induced pain was 25.6 months (range, 1.4–146.4 months), with most symptomatic hip erosion cases presented within the first year (50% presented within the first 6 months) after the index HA surgery. Despite that, only five cases underwent conversion to THA (0.2%) while seven patients received conservative management. Conclusions: In patients older than 65 years of age who are candidates for HA, the incidence of symptomatic hip erosion and the subsequent conversion to THA is low and hence HA remains a viable treatment option. Based on the duration until clinical presentation of acetabular erosion, this study suggests that the state of acetabular cartilage during surgery may influence the development of early acetabular wear in most symptomatic patients. On the other hand, hip hemiarthroplasty is a rare treatment option for displaced femoral neck fractures in patients younger than 65 years of age, and its use in this patient subset depends on conditional and patient-related factors such as the activity level, cognitive function, and medical comorbidities.

DNA methylation is the epigenetic pathway controlling cellular gene expression. Methylation is a natural and cellular epigenetic mechanism for gene silencing. The fact that the genes that the cell decides to be silent do not speak or begin to speak may coincide with diseases. For explanatory evidence, changes at the DNA level can provide realistic information. Wnt/β-catenin signaling has an important role in the pain process. For this purpose, we investigated the relationship between clinical data, wingless-type MMTV integration site family, member 5A (WNT5A), and Frizzled Class Receptor 3 (FZD3) gene methylation and expression in a cohort of tension-type headache (TTH) patients (N = 130) and healthy control (N = 117) individuals. Comorbidities were evaluated. Methylation profiling was performed using Real-Time PCR with a TaqMan primer-probe. The diagnostic power (receiver operating characteristic—ROC) was determined according to the expression and methylation status. Ultimately, WNT5A was found to be upregulated and hypermethylated, and FZD3 was found to be upregulated and hypomethylated. Finally, the area under the curve (AUC) data for FZD3 upregulation (0.983) and hypomethylation (0.866) showed diagnostic values. WNT5A and FZD3 may contribute to the pathogenesis of the disease depending on their expression and methylation profile during the TTH process. At the same time, diagnostic powers have the potential to be a resource for early treatment and new therapeutic approaches. Full article

In 2018, the WHO published a methodology for conducting a point prevalence survey (PPS) of antibiotic use in hospitals. The aim of this study is to report the use of antibiotics in six second-level hospitals in Mexico using this methodology. Methods: A multicenter cross-sectional study based on the 2021–2023 adaptation for Latin American hospitals was conducted in internal medicine, surgery, intensive care unit (ICU), obstetrics and gynecology and pediatrics departments of the IMSS in the western region of the state of Mexico. Results: The overall prevalence of antibiotic use was 61%; the services with the highest prevalence of prescription were general surgery (79%) and the ICU (78%). A total of 846 patients were surveyed; there were no differences in antibiotic use or non-use in terms of gender, surgical procedure and invasive devices, but there were differences in median age and comorbidities. Adherence to guidelines was 53.9%. The three main antibiotics used were third-generation cephalosporins (28%), carbapenems (13%) and glycopeptides (9%); for the type of indication, for CAI and prophylaxis, the rates of use of third-generation cephalosporins were 29.2% and 44.5%, respectively, while for healthcare-associated infections, carbapenems were used (23.9%). By AWaRe group, the watch group was predominant for all types (63.9%), for prophylaxis it was the access group (39.3%), and for HAIs it was the reserve group (4.9%). Full article

Background: Gout is a chronic inflammatory condition characterized by elevated uric acid levels in the blood, which can precipitate acute gout attacks in individuals with genetic susceptibility, existing medical conditions, and dietary influences. Genetic predispositions, comorbid medical conditions, nutritional choices, and environmental factors increasingly recognize the multifactorial etiology of the disease. Methods: Recent research has highlighted the potential of phytochemicals, particularly flavonoids, saponins, and alkaloids, to manage hyperuricemia (HUA) and its associated complications. Results: Plant’s natural compounds have garnered attention for their anti-inflammatory, antioxidant, and uric acid-lowering properties, suggesting their role in alternative and complementary medicine. Phytochemicals have demonstrated promise in mitigating gout symptoms and potentially modifying the disease course by addressing different aspects of hyperuricemia and inflammation. Herbal remedies, with their complex phytochemical profiles, offer a unique advantage by potentially complementing conventional pharmacological treatments. The integration of herbal therapies with standard medications could lead to enhanced therapeutic outcomes through synergistic effects, optimizing disease management, and improving patient quality of life. Conclusions: This review examines the current understanding of the multifaceted etiology of gout, explores the role of phytochemicals in managing hyperuricemia, and discusses the potential benefits of combining herbal remedies with conventional treatments to improve patient care and therapeutic efficacy.

The impact of common respiratory virus infections on adults and older individuals in the community is unclear, excluding seasonal influenza viruses. We examined FilmArray® tests performed on 1828 children aged < 10 years and 10,803 adults, including cases with few respiratory symptoms, between January 2021 and June 2024. Approximately 80% of the children tested positive for ≥ 1 viruses, while 9.5% of the adults tested positive mostly for severe acute respiratory syndrome corona virus-2 (SARS-CoV-2). Besides SARS-CoV-2 infection, 66 out of 97 patients (68.0%) aged > 60 years with rhinovirus/enterovirus (RV/EV), respiratory syncytial virus (RSV), parainfluenza virus-3 (PIV-3), or human metapneumovirus (hMPV) infection required hospitalization, of whom seven died; 26 out of 160 patients (16.3%) aged < 60 years required hospitalization mostly because of deterioration of bronchial asthma, with no reported deaths. In older patients with RV/EV infection, three with few respiratory symptoms died due to worsened heart failure. Although the frequency of common respiratory virus infections in older adults is low, it may be overlooked because of subclinical respiratory symptoms, and its clinical significance in worsening comorbidities in older adults should not be underestimated.

Background: The gut–lung axis could be a potential therapeutic target for improving post-acute COVID-19 symptoms, and probiotics have been proposed as possible modulators. Aim: We conducted a pilot study to understand alterations in the gut–lung axis and to explore the effects of a probiotic in post-acute COVID-19 disease. Methods: We included patients after severe COVID-19 disease (sCOV, n = 21) in a randomized, placebo-controlled trial to test the effect of a probiotic (Pro-Vi 5, Institute Allergosan, Graz, Austria) in a six-month intervention and used patients after mild disease (mCOV, n = 10) as controls, to compare the intestinal microbiome, metabolome, and patient-reported outcomes and biomarkers along the gut–lung axis at baseline and throughout probiotic intervention. Results: Compared to mCOV patients, sCOV patients showed lower microbial richness, which was significantly improved by probiotic intervention. A reorganization of Ruminococcaceae and Lachnospiraceae taxa was observed in sCOV patients but remained unaffected by the intervention. Serum metabolome showed a dysregulation of lipoproteins in accordance with higher BMI and comorbidities in sCOV patients. HDL and LDL fractions/components were temporarily decreased in the probiotic group. Stool metabolome was altered at baseline in sCOV patients and an increase in L-DOPA after 3 months and butyrate after 6 months of intervention could be observed. Probiotics partially improved reduced quality of life and modulated altered immune responses in sCOV patients. Increased intestinal permeability at baseline remained unaffected. Conclusion: The study provides evidence of long-term alterations of the gut–lung axis after severe COVID-19 infection and suggests that probiotics can modulate the biomarkers of the gut–lung axis.

Background: Obstructive sleep apnoea syndrome (OSAS) is an independent risk factor for cardiovascular morbidity and mortality and has a detrimental effect on vascular function, in particular on arterial stiffness and endothelial function. Continuous positive airway pressure (CPAP) is the gold-standard therapy for OSAS and its effects on arterial stiffness and endothelial function have been demonstrated in non-elderly patients. Objectives: The objective of this study was to evaluate the effect of one year of CPAP treatment on arterial stiffness, through assessment of carotid–femoral pulse wave velocity (cf-PWV), and on endothelial function, through the reactive hyperaemia index (RHi), in a real-life cohort of elderly patients with moderate-to-severe OSAS and several comorbidities. Methods: In this nonrandomised prospective study, we enrolled 469 consecutive elderly patients affected by moderate-to-severe OSAS distributed in two groups: CPAP-treated (n = 225) and untreated patients (n = 244). Results: At one-year follow-up, in the treated group emerged an important improvement in poligraphics (AHI, ODI, TC90, mean SpO₂%), laboratory (HOMA index, eGFR, hs-CRP) and vascular function parameters: cf-PWV. The stepwise multivariate linear regression demonstrated a significant correlation between the delta of the polygraph parameters and the delta of PWV and RHi. Conclusions: Our study confirmed the favourable effects of CPAP therapy in a cohort of elderly patients affected by OSAS and several comorbidities on sleep respiratory parameters and vascular function; early diagnosis and treatment with CPAP might be beneficial to delay or prevent the occurrence of cardiovascular events in these groups of patients.

Background: Dalbavancin is a long-acting lipoglycopeptide, approved for treatment of skin and skin structure infections. Its PK/PD profile and safety allow for short hospital stays even in the case of difficult-to-treat infections requiring long courses of therapy, e.g., osteomyelitis, cardiovascular, and prosthetic infections. Objectives: We aimed to evaluate the safety and efficacy of dalbavancin in real life settings for both in-label and off-label indications. Methods: retrospective evaluation of all consecutive patients treated with dalbavancin at our site between May 2017 and September 2021. Results: A total of 100 patients treated with dalbavancin and followed up for 6 months after treatment (58% male; median age 63.5 years, median Charlson Comorbidity Index CCI = 2.7, 28% inpatients) were included with the following indications: acute bacterial skin and skin structure infections (22%), bone and prosthetic infections (57%), and cardiovascular infections (19%). Infections were caused by MSSA (30%), MRSA (5%), MR-CoNS (20%), and Streptococcus spp. (8%). In 32 cases, no isolate was obtained. The average number of infusions was 5 (s.d. = 3). Neither ensuing alteration of renal function nor neutropenia or thrombocytopenia were observed during treatment and follow-up. Two self-limiting skin rashes occurred. The overall clinical success rate was 84%—91% for registered and 82% for unregistered indications. The prescription of higher loading doses was the only predictor independently associated with better outcomes in multivariate models (OR: 5.2, 95%CI: 1.5–17.9, p < 0.01). Conclusions: Dalbavancin proved to be effective for skin and skin structure infections, as well as for difficult-to-treat infections in highly comorbid patients. Regarding tolerability, our results support the use of dalbavancin for long-lasting treatments of deep-seated infections. Full article

Background/Objectives: The aim of this study was to assess auditory development in young children with profound hearing loss, cochlear implants (CIs), and congenital cytomegalovirus (cCMV) infection and to determine the effect of comorbidities on their development. Methods: The study group (cCMV group) consisted of 47 CI children—18 girls and 29 boys—who had been diagnosed as having prelingual hearing loss due to cCMV infection (with or without comorbidities); the mean age at CI activation was 15.2 months (range: 9.7–23.8; SD = 3.5). The reference group (no cCMV) consisted of 117 similar children (57 girls and 60 boys) who had profound sensorineural hearing loss not caused by cCMV infection; they had no comorbidities. The mean age at CI activation in the second group was 14.3 months (range: 7.9–23.5; SD = 4.0). Auditory development in all children was assessed with the LittlEARS Auditory Questionnaire (LEAQ) at CI activation and at about 1, 5, 9, 14, and 24 months of CI use. Results: The mean LEAQ total score increased over a similar time frame from 9.8 pts to 28.9 pts in the cCMV group without comorbidities, from 4.5 pts to 18.5 pts in the cCMV group with comorbidities, and from 9.2 to 31.6 pts in the reference group with no cCMV infection. Conclusions: Early cochlear implantation in children with sensorineural hearing loss due to congenital CMV infection and no comorbidities promotes their early auditory development in a similar way to children without cCMV infection.

Objectives: The choice of vascular access continues to be a critical component in the management of hemodialysis patients. Despite the international consensus favoring arteriovenous (AV) fistulas, the use of central venous catheters (CVCs) remains prevalent, with substantial variations across countries and even among dialysis centers within the same region. This study examines the prevalence of CVC use among chronic hemodialysis (CHD) patients in Vienna, Austria, and explores inter-center differences. Methods: A cross-sectional analysis was conducted on patients receiving CVC-based CHD in Vienna as of March 2023. Patient demographics, comorbidities and their hemodialysis history were collected. Additionally, a subset of the population underwent vascular access (VA) mapping to assess eligibility for AV fistula (AVF) or AV graft (AVG) creation. Results: A total of 335 patients received CVC-based hemodialysis, equaling a CVC proportion of 42.5%. 191 (57.0%) patients on CVC-based CHD gave their consent to record their clinical data and vascular access history. Of the 191 included patients, 61 gave their consent to receive VA mapping. Of the 61 patients who received VA mapping, 60 (98.4%) were eligible for an upper extremity AVF or AVG. There was no significant difference regarding patient demographics, dialysis vintage, history of previous AVF or AVG or Charlson Comorbidity Index between the mapping and non-mapping group. The odds ratio of having a CVC in the absence of in-house vascular surgery was 3.41 (95% CI: 2.31–5.02, p-value < 0.001) compared to patients with in-house vascular surgery. Conclusions: The majority of patients that consented to ultrasound VA mapping fulfilled vascular requirements for AVF or AVG creation. Our study highlights the potential to decrease the prevalence of CVC-based CHD in Vienna that could translate to a reduction in CVC-associated complications. Full article

Introduction: Laparoscopic sleeve gastrectomy (LSG) is a widely performed bariatric surgery across the globe. Understanding preoperative risk factors for possible intraoperative complications can aid in predicting surgical outcomes and shaping the approach to the procedure. This study aimed to identify and analyze potential risk factors associated with intraoperative difficulties during LSG. Patients and methods: The analysis encompassed consecutive patients who underwent LSG from 2017 to 2020. Patients who encountered intraoperative difficulties during the procedure were categorized into Group 1, whereas those who did not experience such complications were placed in Group 2. To identify potential risk factors for intraoperative challenges, a thorough evaluation of demographic characteristics was conducted, including variables such as age, body mass index (BMI), comorbidities, and previous surgical history. Results: Group 1 included 37 patients (11.71%), while Group 2 comprised 279 patients (88.29%). Apart from higher rates of diabetes, pulmonary disease, and sleep apnea in Group 1, no significant differences were observed between the groups regarding demographic parameters. A univariate logistic regression analysis identified several risk factors associated with intraoperative difficulties, including a body mass index (BMI) greater than 50 kg/m² (OR 2.15, 95%, CI 1.05–4.39, p = 0.0362), the experience of the operating surgeon (OR 9.22, 95% CI 4.31–19.72, p = 0.0058), the presence of diabetes (OR 2.44, 95% CI 1.19–4.98, p = 0.0146), and pulmonary disease (OR 12.22, 95% CI 1.97–75.75, p < 0.0001). In multivariate logistic regression analysis, only the surgeon’s experience (OR 8.61, 95% CI 3.75–19.72, p < 0.0001) remained a significant factor influencing intraoperative difficulties. Conclusions: The sole significant factor influencing the occurrence of intraoperative difficulties was the level of the surgeon’s experience Full article
