Regional insights on tobacco-related tweets: unveiling user opinions and usage patterns.
No full text20.500.12530/87855Tobacco consumption and its impact on health remain high worldwide. Additionally, it is a contentious issue generating significant controversy. Twitter has proven to be a useful platform for evaluating public health topics related to population health behaviors, and tobacco consumption. The objective of this study is to analyze the content of tweets related to tobacco. Moreover, geolocation data will be considered to understand regional differences. Tweets published between 2018 and 2022, in both English and Spanish, containing the keyword "tobacco," were analyzed. A total of 56,926 tweets were obtained. The tweets were classified into different categories. 550 tweets were manually analyzed, and an automated and computerized classification was performed for the remaining and largest subset of tweets. The analysis yielded 30,812 classifiable tweets. Healthcare professionals were the most frequent contributors to the topic (50.2%), with the most common theme being general information about the toxic effects of tobacco. 57.9% of the tweets discussed the harmful effects of tobacco on health, with fear being the predominant emotion. The largest number of tweets were located in America. Our study revealed a substantial number of tweets highlighting the health risks and negative perceptions of tobacco consumption. Africa showed the lowest percentage of tweets discussing the health risks associated with tobacco, coinciding with the continent having the least developed anti-tobacco policies. Healthcare professionals emerged as the most prominent users discussing the topic, which is encouraging as they play a crucial role in disseminating accurate and scientific health information
Benefit of isolated surgical valve repair or replacement for functional tricuspid regurgitation and long-term outcomes stratified by the TRI-SCORE.
No full text20.500.12530/87855Severe tricuspid regurgitation is associated with increased mortality rates, but benefit of its correction and ideal timing are not clearly determined. This study aimed to identify patient subsets who might benefit from the surgery. In TRIGISTRY, an international cohort study of consecutive patients with severe isolated functional tricuspid regurgitation (33 centres, 10 countries), survival rates up to 10 years were compared between patients who underwent isolated tricuspid valve surgery (repair or replacement) and those conservatively managed, overall and according to TRI-SCORE category (low: ≤3, intermediate: 4-5, and high: ≥6). One thousand and two hundred seventeen were managed conservatively, and 551 underwent isolated tricuspid valve surgery (200 repairs and 351 replacements). TRI-SCORE distribution was 33% low, 32% intermediate, and 35% high. At 10 years, survival rates were similar between surgical and conservative management [41% vs. 36%; hazard ratio (HR) .97; 95% confidence interval (CI) .88-1.08, P = .57]. Surgery improved survival compared with conservative management in the low TRI-SCORE category (72% vs. 44%; HR .27; 95% CI .20-.37, P Higher survival rates were observed with repair than replacement and benefit of intervention declined as TRI-SCORE increased with no benefit of any type of surgery in the high TRI-SCORE category. These results emphasize the importance of timely intervention and patient selection to achieve the best outcomes and the need for randomized controlled trials
SEOM-GEMCAD-TTD clinical guidelines for the management of hepatocarcinoma patients (2023).
No full text20.500.12530/87912Hepatocellular carcinoma (HCC) is the most common primary malignancy in the liver and is the third cause of cancer-related death worldwide. Surveillance with abdominal ultrasound should be offered to individuals at high risk for developing HCC. Accurate diagnosis, staging, and liver function are crucial when determining the optimal therapeutic approach. The BCLC staging system is widely endorsed in Western countries. Managing this pathology requires a multidisciplinary, personalized approach, generally with a multimodal strategy. Surgery remains the only curative option, albeit local and systemic therapy may also increase survival when surgery is not suitable. In advanced disease, systemic treatment should be offered to patients with ECOG/PS 0-1 and Child-Pugh class A
Can We Differentiate Between Organic and Functional Bladder Outlet Obstruction in Males With Parkinson's Disease?
No full textTo determine the type of bladder outlet obstruction (BOO) in patients with Parkinson's disease (PD). A case-control study was carried out in 46 patients divided into two groups. Group 1 formed by 23 PD patients with BOO (a URA parameter ≥ 29 cm H2O). Group 2 formed by 23 patients with benign prostatic hyperplasia (BPH) and compressive obstruction (an opening pressure > 35 cm H2O) and URA parameter ≥ 29 cm H2O). Both groups underwent a pressure-flow study to calculate Dynamic Urethral Resistance Relationship (DURR) patterns. Based on previous research, we describe two types of DURR pattern. Pattern A typical of dynamic or functional obstruction and pattern B typical of static or organic obstruction. We found that PD patients had a significantly higher frequency of pattern A (70%) than BPH patients (4%). Other significant differences between groups were age (greater in PD group), bladder compliance (greater in PD group), maximum flow rate [Qmax (greater in BPH group)], maximum detrusor pressure [Pmax (greater in BPH group)], detrusor pressure at maximum flow rate [PQmax (greater in BPH group)], opening detrusor pressure (greater in BPH group), and the bladder contractility parameters BCI and Wmax (greater in BPH group). There were no significant differences in perineal voiding electromyography (EMG) activity between groups nor relationship between voiding EMG activity and the type of DURR pattern. Our results are consistent with the usefulness of the DURR pattern to differentiate between functional and organic BOO in PD patients. Most PD patients have functional obstruction although a minority has organic obstruction consistent with BPH
An intragenic duplication in the AFF2 gene associated with Cornelia de Lange syndrome phenotype.
No full text20.500.12530/87857Cornelia de Lange syndrome (CdLS, OMIM #122470, #300590, #300882, #610759, and #614701) is a rare congenital disorder that affects the development of multiple organs and is characterized by physical abnormalities and cognitive and behavioral disabilities. Its molecular basis is mainly based on alterations in genes encoding structural and regulatory proteins related to the cohesin complex. Moreover, other transcriptional regulatory factors have been linked to this syndrome. However, additional causative genes are still unknown, since many patients still lack a molecular diagnosis. Herein, we describe a case with multiple affected family members presenting with an intragenic duplication in the AFF2 gene. The direct tandem intragenic duplication of exons 10, 11 and 12 was detected through high-resolution array Comparative Genomic Hybridization and next-generation sequencing technologies. Confirming the X-linked inheritance pattern, the duplication was found in the patient, his mother and his maternal aunt affected (dizygotic twins). Targeted sequencing with Oxford Nanopore Technologies revealed an aberrant transcript which is predominantly expressed in the patient and his aunt. Along with these results, a significant reduction in AFF2 gene expression levels was detected in these two individuals. Clinically both subjects exhibit a classic CdLS phenotype, whereas the mother is mostly unaffected. Consistent with the phenotypical differences observed between the mother and the aunt, there is a marked difference in X-inactivation patterns skewing. Given the crucial role of AFF2 in transcriptional regulation, it is not surprising that AFF2 variants can give rise to CdLS phenotypes. Therefore, the AFF2 gene should be considered for the molecular diagnosis of this syndrome
[Translated article] Bibliometric Study of the Advances Made in Clinical Dermatological Research in Spain from 2015 through 2021: Update of the MaIND Project and Interactive Online Map.
No full text20.500.12530/87909A clinical dermatological research was conducted in Spain from 2005 through 2014 as part of the MaIND project with the provinces or centers with the highest number of published articles. However, a low level of evidence in scientific production was confirmed as the overall result. The aim of this study is to update the Spanish clinical dermatological research in bibliometric terms from 2015 through 2021 with comparisons between both periods of time. We conducted a bibliometric study to replicate the methodology used in the article to be updated. We included articles whose corresponding authors' affiliation was a Spanish dermatological center, which met the criteria for clinical research in dermatology, including a level of evidence ≤4. A total of 1,674 out of the 10,199 articles met the inclusion criteria. An interactive map representing quantitative and qualitative indicators calculated for the 2005-2021 is presented here. In the study period, we found an increasing trend both in the number of published articles (P4, with a positive trend towards more articles having a higher level of evidence (P The results of this study show that, in Spain, the scientific production of dermatology represents an upward trend in quantity, impact, and level of evidence
Rheumatoid meningitis: a case series report and review of modern therapeutic schemes and outcome.
No full text20.500.12530/87858Rheumatoid meningitis (RM) is an extremely rare extra-articular complication of rheumatoid arthritis (RA), with approximately 165 cases reported world-wide. RM exhibits a broad range of symptoms, with stroke-like episodes and seizures being the most common manifestations. The primary differential diagnoses include vascular and infectious diseases. The influence of immunomodulatory medications on the pathophysiology of RM remains unclear. There are no consensus guidelines on therapeutic regimen. We present four patients with prior history of RA that developed different neurological syndromes in correlation to radiological leptomeningitis. Clinical presentations, comorbid conditions, supplementary diagnostic assessments, treatments, and prognosis are provided. A literature review of recent immunosuppressive management in RM patients was performed. Three patients presented to hospital with recurrent focal seizures. Only two suffered meningism, reporting headache and fever. Magnetic resonance imaging (MRI) showed different grades of leptomeningitis across all cases. Notably, three cases demonstrated bilateral involvement extending to the pachymeninges. Two patients exhibited pronounced CSF mononuclear inflammation while extended microbiological evaluations yielded negative results. Two patients required biopsy for confirmation. The initiation of immunosuppressive therapy marked a turning point for three patients who previously exhibited progressive deterioration. Mortality was absent in all cases. Our experience remarks the elusive nature of RM. Rigorous exclusionary diagnostics are imperative to differentiate RM from mimicking conditions. Clinical manifestations oscillate between transient episodes and progressive neurological impairments, punctuated by frequent epileptic seizures. In scenarios where clinical worsening persists or where clinical and radiological evaluations are inconclusive, aggressive immunosuppressive therapy is recommended
Novel risk loci for COVID-19 hospitalization among admixed American populations.
No full text20.500.12530/87845The genetic basis of severe COVID-19 has been thoroughly studied, and many genetic risk factors shared between populations have been identified. However, reduced sample sizes from non-European groups have limited the discovery of population-specific common risk loci. In this second study nested in the SCOURGE consortium, we conducted a genome-wide association study (GWAS) for COVID-19 hospitalization in admixed Americans, comprising a total of 4702 hospitalized cases recruited by SCOURGE and seven other participating studies in the COVID-19 Host Genetic Initiative. We identified four genome-wide significant associations, two of which constitute novel loci and were first discovered in Latin American populations (BAZ2B and DDIAS). A trans-ethnic meta-analysis revealed another novel cross-population risk locus in CREBBP. Finally, we assessed the performance of a cross-ancestry polygenic risk score in the SCOURGE admixed American cohort. This study constitutes the largest GWAS for COVID-19 hospitalization in admixed Latin Americans conducted to date. This allowed to reveal novel risk loci and emphasize the need of considering the diversity of populations in genomic research
Fecal microbiota transplantation from female donors restores gut permeability and reduces liver injury and inflammation in middle-aged male mice exposed to alcohol.
No full text20.500.12530/87858Alcohol misuse, binge drinking pattern, and gender-specific effects in the middle-aged population has been clearly underestimated. In the present study, we focused on understanding gender-specific effects of alcohol exposure on the gut-liver axis and the role of gut microbiota in modulating gender-specific responses to alcohol consumption. Fifty-two-week-old female and male C57BL/6 mice were fasted for 12 h, and then administered a single oral dose of ethanol (EtOH) (6 g/kg). Controls were given a single dose of PBS. Animals were sacrificed 8 h later. Alternatively, fecal microbiota transplantation (FMT) was performed in 52-week-old male mice from female donors of the same age. Permeability of the large intestine (colon), gut microbiota, liver injury, and inflammation was thoroughly evaluated in all groups. Middle-aged male mice exposed to EtOH showed a significant increase in gut permeability in the large intestine, evaluated by FITC-dextran assay and ZO-1, OCCLUDIN and MUCIN-2 immuno-staining, compared to PBS-treated animals, whilst female mice of the same age also increased their gut permeability, but displayed a partially maintained intestinal barrier integrity. Moreover, there was a significant up-regulation of TLRs and markers of hepatocellular injury, cell death (AST, TUNEL-positive cells) and lipid accumulation (ORO) in male mice after EtOH exposure. Interestingly, FMT from female donors to male mice reduced gut leakiness, modified gut microbiota composition, ameliorated liver injury and inflammation, TLR activation and the senescence phenotype of middle-aged mice. Our findings highlighted the relevance of gender in middle-aged individuals who are exposed to alcohol in the gut-liver axis. Moreover, our study revealed that gender-specific microbiota transplantation might be a plausible therapy in the management of alcohol-related disorders during aging
Predictors, prognosis and costs of prolonged intensive care unit stay after surgery for type A aortic dissection.
No full text20.500.12530/87858The outcomes after prolonged treatment in the intensive care unit (ICU) after surgery for Stanford type A aortic dissection (TAAD) have not been previously investigated. This analysis included 3538 patients from a multicenter study who underwent surgery for acute TAAD and were admitted to the cardiac surgical ICU. The mean length of stay in the cardiac surgical ICU was 9.9±9.5 days. The mean overall costs of treatment in the cardiac surgical ICU 24086±32084 €. In-hospital mortality was 14.8% and 5-year mortality was 30.5%. Adjusted analyses showed that prolonged ICU stay was associated with significantly lower risk of in-hospital mortality (adjusted OR 0.971, 95%CI 0.959-0.982), and of five-year mortality (adjusted OR 0.970, 95%CI 0.962-0.977), respectively. Propensity score matching analysis yielded 870 pairs of patients with short ICU stay (2-5 days) and long ICU stay (>5 days) with balanced baseline, operative and postoperative variables. Patients with prolonged ICU stay (>5 days) had significantly lower in-hospital mortality (8.9% vs. 17.4%, 5 days) with balanced baseline, operative and postoperative variables. Patients with prolonged ICU stay (>5 days) had significantly lower in-hospital mortality (8.9% vs. 17.4%, 5 days) had significantly lower in-hospital mortality (8.9% vs. 17.4%, Prolonged ICU stay was common after surgery for acute TAAD. However, when adjusted for multiple baseline and operative variables as well as adverse postoperative events and the cluster effect of hospitals, it was associated with favorable survival up to 5 years after surgery
