The significance of metabolic alkalosis on acute decompensated heart failure: the ALCALOTIC study.
No full text20.500.12530/87854To determine the prevalence and the impact on prognosis of metabolic alkalosis (MA) in patients admitted for acute heart failure (AHF). The ALCALOTIC is a multicenter, observational cohort study that prospectively included patients admitted for AHF. Patients were classified into four groups according to their acid-base status on admission: acidosis, MA, respiratory alkalosis, and normal pH (reference group for comparison). Primary endpoint was all-cause in-hospital mortality, and secondary endpoints included 30/90-day all-cause mortality, all-cause readmission, and readmission for HF. Associations between endpoints and acid-base alterations were estimated in a multivariate Cox regression model including sex, age, comorbidities, and Barthel index and expressed as hazard ratio (HR) with 95% confidence interval (95% CI). Six hundred sixty-five patients were included (84 years and 57% women), and 40% had acid-base alterations on admission: 188 (28%) acidosis and 78 (12%) alkalosis. The prevalence (95% CI) of MA was 9% (6.8-11.2%). Patients with MA were more women; had fewer comorbidities, better renal function, and higher left ventricle ejection fraction values; and received more treatment with oral acetazolamide during hospitalization and at discharge. MA was not associated with a higher risk of in-hospital mortality and 30/90-day all-cause mortality or readmissions but was associated with a significant increase in readmissions for HF at 30 and 90 days (adjusted HR [95% CI] 3.294 [1.397-7.767], p = 0.006 and 2.314 [1.075-4.978], p = 0.032). The prevalence of MA in patients admitted for AHF was 9%, and its presence was associated with more readmissions for HF but not with all-cause mortality
Smouldering-Associated Worsening in Multiple Sclerosis: An International Consensus Statement on Definition, Biology, Clinical Implications, and Future Directions.
No full text20.500.12530/87858Despite therapeutic suppression of relapses, multiple sclerosis (MS) patients often experience subtle deterioration, which extends beyond the definition of "progression independent of relapsing activity." We propose the concept of smouldering-associated-worsening (SAW), encompassing physical and cognitive symptoms, resulting from smouldering pathological processes, which remain unmet therapeutic targets. We provide a consensus-based framework of possible pathological substrates and manifestations of smouldering MS, and we discuss clinical, radiological, and serum/cerebrospinal fluid biomarkers for potentially monitoring SAW. Finally, we share considerations for optimizing disease surveillance and implications for clinical trials to promote the integration of smouldering MS into routine practice and future research efforts.

A multi-center study on the use of lidocaine thermogel for pain control in outpatient operative hysteroscopy.
No full text20.500.12530/87855This study aimed to explore the use of an anesthetic lidocaine thermogel in outpatient operative hysteroscopies. Specifically, it assessed the safety, tolerability, and ease of use of the gel, as well as its potential for pain reduction during the procedure. This was a multicenter observational study conducted in 9 gynecological units between March 2023 and January 2024. The study included adult women scheduled for outpatient operative hysteroscopies, excluding those with hypersensitivity to the product or recent participation in other clinical studies. The target sample size was 60 to account for potential dropouts. Data collection was electronic, and SPSS was used for analysis. The study assessed visibility conditions, procedure duration, pain scores at different stages of the procedure, and adverse event frequency. Statistical analyses utilized descriptive statistics, Student's t-tests, Wilcoxon and Friedman tests, and Chi-Square or Fisher tests as appropriate. Binary logistic regression was applied to identify factors influencing gel volume. All 60 participants met the inclusion criteria. The mean age was 45.5 (SD 8.8) years, with a mean BMI of 27.0 (SD 5.6) kg/m2. Medical histories were reported in 46.7% of participants, and 50% had undergone previous gynecological surgeries. Prior to the procedure, 51.8% of participants took analgesics. The average procedure duration was 13.9 (SD 15.1) minutes. Pain scores were collected at different stages of the procedure, with median VAS scores ranging from 0 to 5 out of 10. In 50% of cases, the quality of vision during the procedure was rated 9 or higher on a 10-point scale. The full recommended dose of thermogel was administered in 91.7% of cases. The mean gel volume used was 7.0 (SD 1.9) milliliters. Regression analysis showed that younger age and a history of abortions or childbirth were significantly associated with higher gel volume use. The anesthetic thermogel demonstrated effectiveness in managing pain during outpatient operative hysteroscopies, with median pain scores ranging from 0 to 5 out of 10 across different stages of the procedure. The gel showed a favorable safety profile, with only 15% of participants reporting adverse effects, all of which were minor and resolved satisfactorily. The high rate of complete gel application (91.7% of cases) and positive physician feedback suggest good tolerability and ease of use. Further research is recommended to evaluate the gel's efficacy in other gynecological procedures and to optimize application protocols based on patient-specific factors such as age and reproductive history
PARASTOMAL HERNIA REPAIR IN BRICKER TYPE URINARY DIVERSION USING THE MODIFIED PAULI TECHNIQUE: A CASE REPORT
No full textAge- and Sex-Related Differences in Patients With Wild-Type Transthyretin Amyloidosis: Insights From THAOS.
No full textWild-type transthyretin amyloidosis (ATTRwt amyloidosis) is primarily diagnosed in elderly men but diagnoses in younger patients and women have recently increased. The purpose of this study was to examine age- and sex-related differences in patients with ATTRwt amyloidosis enrolled in the THAOS (Transthyretin Amyloidosis Outcomes Survey). THAOS was a global, longitudinal, observational survey of patients with transthyretin amyloidosis, including both hereditary and wild-type disease, and asymptomatic carriers of pathogenic transthyretin gene variants. Patient characteristics at enrollment were analyzed by age at enrollment and sex (data cutoff date: August 1, 2022). Of 1,251 patients with ATTRwt amyloidosis, 13.7%, 49.1%, 34.5%, and 2.8% were aged In this THAOS analysis of patients with ATTRwt amyloidosis, patients were diagnosed an average of 2 years after symptom onset, with the greatest diagnostic delay in women aged
Is immediate weight bearing safe for subtrochanteric femur fractures in elderly patients treated by cephalomedullary nailing? A multicentric study in one hundred eighty-two patients.
No full text20.500.12530/87855Biomechanical superiority of intramedullary nails over extramedullary implants has been proved for subtrochanteric fractures. Nevertheless, postoperative management of these patients has not changed, with high rates of protected weight-bearing after intramedullary nailing. The purpose of this study is to determine the mechanical complications of immediate postoperative full weigh-bearing for subtrochanteric femur fractures in elderly patients treated with a cephalomedullary nail. We performed a retrospective case series study from patients treated with a cephalomedullary nail for subtrochanteric fractures (AO/OTA 31A.3 and 32A-32C) over a nine-year period. Patients in the immediate full weight-bearing (IFWB) group received orders for immediate full weight bear as tolerated on postoperative 48 h. Patients in the non- or limited- weight-bearing (NLWB) group received orders not to full weight bear in the immediate postoperative. There were five (2.7%) cases of implant failure including four cutouts and one nail breakage that needed a reoperation. Of them, one (2.2%) followed the NLWB protocol and four (2.9%) followed the IFWB protocol. Mean length of stay was 7.9 days (median 8, range 3-21) in the NLWB group and 10.7 days (median 8, range 2-60) in the IWBAT group. The NLWB group observed a 2.8-day shorter postoperative length of stay when compared to the IFWB, but the median remained equal. This study suggests that geriatric patients with subtrochanteric fractures treated by intramedullary nailing and in which a good fracture reduction was achieved, may be able to tolerate immediate postoperative full weight-bearing, not increasing reoperation rates due to implant failure
Effectiveness of Treatment Approaches in COVID-19 Pneumonia: A Comparative Evaluation between a Specialized Center and Conventional Hospitals.
No full text20.500.12530/87849The early stages of the COVID-19 pandemic overwhelmed general hospitals in Spain. In response, a dedicated hospital for COVID-19 care, the Hospital de Emergencias Enfermera Isabel Zendal (HEEIZ), was established. This study aimed to compare clinical outcomes of COVID-19 patients treated at the specialized HEEIZ with those at conventional general hospitals (CGHs) in Madrid, Spain. The study was a prospective, observational cohort study including COVID-19 patients admitted to the HEEIZ and 14 CGHs (December 2020 to August 2021). Patients were assigned based on hospital preference. Clinical data were collected and analyzed using multivariate regression to assess primary and secondary outcomes, including hospital mortality, need of invasive mechanical ventilation (IMV), and pharmacological treatments. The HEEIZ cohort (n = 2997) was younger and had lower Charlson comorbidity scores than the CGH cohort (n = 1526). Adjusted HEEIZ hospital mortality was not significantly higher compared with CGHs (OR: 1.274; 95% CI: 0.781-2.079; p = 0.332). During the study period, patients admitted to the HEEIZ showed no significant differences in clinical outcomes, compared with patients admitted at CGHs. These results might support the use of specialized centers in managing pandemic surges, allowing CGHs to handle other needs
Tivozanib Monotherapy in the Frontline Setting for Patients with Metastatic Renal Cell Carcinoma and Favorable Prognosis.
No full text20.500.12530/87910In this review, we discuss which patients with metastatic clear cell renal cell carcinoma (mRCC) may be most suitable for frontline tyrosine kinase inhibitor (TKI) monotherapy, a treatment option supported by emerging long-term efficacy data including overall survival and quality of life. We specifically focus on tivozanib, a potent and selective inhibitor of vascular endothelial growth factor receptor, which has comparable efficacy to other single-agent TKIs in frontline treatment for mRCC while exhibiting fewer off-target side effects. Combination therapy with TKIs and checkpoint inhibitors (CPIs) and CPI/CPI combination therapies, as well as TKI monotherapy are recommended frontline treatment options for mRCC. Treatment decisions are complex and based on several factors, including the patient's International Metastatic RCC Database Consortium risk status, age, comorbidities, and personal preferences related to response, tolerability, and quality of life. TKIs not only serve as backbone of most combination therapies for mRCC, but also remain a viable monotherapy option in the first-line setting for patients in favorable risk groups and those with contraindications to CPI combination therapies. Given that overall survival benefits have not yet been confirmed for CPI-containing combination regimens in favorable risk patients, we argue that frontline single-agent TKI treatment remains a standard of care option for these patients. This is supported by treatment guidelines, even in the era of TKI/CPI combination therapies
Encuesta sobre la actividad de los laboratorios de función pulmonar. Efectos durante la pandemia por SARS-CoV-2.
No full text20.500.12530/87858Following the SARS-CoV-2 pandemic in March 2020, pulmonary function testing (PFT) laboratories underwent a transformation, with a reduction in the number of tests or closure in some cases. The aim of this work was to know the activity of PFT in Spain and the modification of this activity due to the pandemic. A protocolised survey was carried out to members of the PFT laboratories through the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Thirty-nine hospitals in Spain responded. The pulmonary function tests most frequently performed in the PFT laboratories were forced spirometry with bronchodilator test (100%), body plethysmography (97.4%), CO transfer capacity (97.4%), respiratory muscle strength measured in the mouth (97.4%), 6-minute walking test (94.7%), measurement of exhaled fraction of nitric oxide (92.3%) and incremental exercise test (71.8%).The pandemic led to a significant decrease in the number of tests (35.4%) during 2020 with subsequent recovery in 2021, without reaching pre-pandemic values.The most important changes were increased examination times, working with personal protective equipment and ventilation of the rooms. The performance of the nasopharyngeal swab for SARS-CoV2 testing prior to the tests was not homogeneous in the PFT laboratories. Most hospitals are sufficiently equipped to perform the most common pulmonary function tests. The pandemic resulted in a loss of activity in all hospitals
Impact of mechanical power on ICU mortality in ventilated critically ill patients: a retrospective study with continuous real-life data.
No full text20.500.12530/87860Over the past decade, numerous studies on potential factors contributing to ventilation-induced lung injury have been carried out. Mechanical power has been pointed out as the parameter that encloses all ventilation-induced lung injury-contributing factors. However, studies conducted to date provide data regarding mechanical power during the early hours of mechanical ventilation that may not accurately reflect the impact of power throughout the period of mechanical ventilatory support on intensive care unit mortality. Retrospective observational study conducted at a single center in Spain. Patients admitted to the intensive care unit, > o = 18 years of age, and ventilated for over 24 h were included. We extracted the mechanical power values throughout the entire mechanical ventilation in controlled modes period from the clinical information system every 2 min. First, we calculate the cutoff-point for mechanical power beyond which there was a greater change in the probability of death. After, the sum of time values above the safe cut-off point was calculated to obtain the value in hours. We analyzed if the number of hours the patient was under ventilation with a mechanical power above the safe threshold was associated with intensive care unit mortality, invasive mechanical ventilation days, and intensive care unit length of stay. We repeated the analysis in different subgroups based on the degree of hypoxemia and in patients with SARS CoV-2 pneumonia. The cut-off point of mechanical power at with there is a higher increase in intensive care unit mortality was 18 J/min. The greater the number of hours patients were under mechanical power > 18 J/min the higher the intensive care unit mortality in all the study population, in patients with SARS CoV-2 pneumonia and in mild to moderate hypoxemic respiratory failure. The risk of death in the intensive care unit increases 0.1% for each hour with mechanical power exceeding 18 J/min. The number of hours with mechanical power > 18 J/min also affected the days of invasive mechanical ventilation and intensive care unit length of stay. The number of hours with mechanical power > 18 J/min is associated with mortality in the intensive care unit in critically ill patients. Continuous monitoring of mechanical power in controlled modes using an automated clinical information system could alert the clinician to this risk
