Incidence of pregnancy related pulmonary embolism in Spain 2016-2021: an observational population-based retrospective study.

OBJECTIVE: This study aimed to estimate the overall and annual age-standardized incidence of pregnancy-related pulmonary embolism (PE) in Spain from 2016 to 2021, explore the distribution of PE events during pregnancy and the postpartum period, identify potential risk factors, and estimate mortality rates during hospital admission. METHODS: In a retrospective, observational, population-based study, data from the Spanish National Hospital Discharge Database were analyzed to identify women with hospital episodes of pregnancy-related-PE. The primary outcome was the overall and annual age-standardized incidence of pregnancy-related-PE, with secondary aims including the distribution of events during pregnancy and postpartum and the calculation of age-standardized mortality rates during admission. RESULTS: Among 2,178,805 births from 2016 to 2021, 522 women were diagnosed with pregnancy-related PE, yielding an overall age-standardized incidence of 2.83 cases per 10,000 births. A non-significant increasing trend was observed from 2.43 to 4.18 cases per 10,000 births (p = 0.06). Comorbidities were low, with a notable association between PE and SARS-CoV-2 infection during the last two years. The mortality rate among women with pregnancy-related PE was 2.8%, with a higher incidence of PE reported during the postpartum period. CONCLUSION: The incidence of pregnancy-related-PE in Spain exhibits a non-significant increasing trend, with a significant risk of mortality. The association with SARS-CoV-2 infection underscores the importance of vigilant monitoring and management of pregnant women, particularly during pandemics. This study contributes specific data on the incidence and characteristics of pregnancy-related-PE in Spain, emphasizing the need to consider PE in the differential diagnosis and management strategies for pregnant and postpartum women.

Impact of hypochloremia as a prognostic factor in patients with heart failure, a retrospective cohort study.

BACKGROUND: some studies suggest that hypochloremia is a risk factor in the prognosis of heart failure (HF) in patients with recent decompensation. MATERIALS AND METHODS: retrospective cohort study of patients discharged due to HF decompensation who began follow-up in a specialized clinic. Two groups are defined: patients with hypochloremia (chloride < 98 mmol/L) and normochloremic patients (chloride > 98 mmol/L) in the initial assessment within the first month after discharge. The rate of intravenous diuretic rescue, emergency department visits, readmission for HF and cardiovascular (CV) death are compared using a Cox proportional hazards model. RESULTS: 165 patients were included (59% women, mean age 85 years), with 60 (36%) having hypochloremia. Both groups were comparable in terms of baseline characteristics, except for female sex, presence of peripheral artery disease, moderate-to-severe liver disease (more prevalent in the hypochloremia group), PROFUND index, and baseline furosemide dose (higher in patients with hypochloremia). The incidence of the primary event was higher in subjects with hypochloremia than in normochloremic subjects (HR: 1.59, 95% CI 0.97-2.62), mainly due to the need for intravenous diuretic rescue (HR: 1.86, 95% CI 1.07-3.24). CONCLUSIONS: hypochloremia following admission for HF decompensation is associated with a greater need for intravenous diuretic rescue therapy and probably worse overall prognosis across the spectrum of the disease, regardless of left ventricular ejection fraction (LVEF).

Retinal vein occlusion. Audit of a specialized care program.

BACKGROUND AND OBJECTIVES: Retinal vein occlusion (RVO) is the second most frequent cause of retinal vascular disease and is related to classic cardiovascular risk factors. A specific program was designed to detect and treat risk factors in patients with RVO. The aim of this study is to audit the results of this program. PATIENTS AND METHODS: The program consisted of a multidisciplinary clinical evaluation by the Ophthalmology and Internal Medicine Departments. All patients with RVO were screened, at minimum, for hypertension, diabetes, dyslipidemia, smoking, overweight, and antiphospholipid syndrome. New risk factors or poor control of known risk factors were expected to be found in at least one-third of the patients. Among them, therapeutic measures were expected to be taken in at least two-thirds. A dissociated automated search of the data of all patients who entered the program between April 2021 and April 2022 was performed. RESULTS: Fifty-six patients were included for analysis. Of these, 39 (69.6%) had at least one new or poorly controlled risk factor and 43 (76.8%) had their treatment modified in some way. Antiphospholipid syndrome was detected in five (8.9%). Only one patient had low-risk hereditary thrombophilia. After an exhaustive examination, no risk factors were found in 11 patients. CONCLUSION: This specific program has been effective in detecting new or poorly controlled risk factors and improving their treatment.

External validation of the InShape II study algorithm for exclusion of chronic thromboembolic pulmonary hypertension in patients with pulmonary thromboembolism.

BACKGROUND AND AIM: The most severe long-term complication of pulmonary embolism (PE) is chronic thromboembolic pulmonary hypertension (CTEPH), and its early diagnosis often requires numerous diagnostic tests. The InShape II study proposes an early screening algorithm that aims to reduce the number of echocardiographic studies. The objective of our study is to validate this algorithm in our patient cohort. MATERIALS AND METHODS: We retrospectively analyzed patients admitted to Hospital Rey Juan Carlos between November 2017 and February 2020, who were diagnosed with PE based on computed tomography angiography (CTA). Patients were followed for at least one year, and clinical, laboratory, and complementary test data were collected at three months and one year. The InShape II algorithm was applied to these patients to validate its results. RESULTS: During the study period, 236 patients were diagnosed with PE, of which 137 were excluded. The algorithm was validated in 99 patients. Applying the InShape II score, 19 echocardiograms would have been performed (three of them with intermediate-high probability of CTEPH), while 80 echocardiograms would have been avoided (two of them with intermediate-high probability). This yielded a sensitivity of 60% and a specificity of 83% for the score, with an area under the curve (AUC) of 0.715 (95% CI: 0.472-0.958). CONCLUSIONS: Our results support the notion that the InShape II algorithm could be a useful tool for initial screening of CTEPH in low-incidence settings, as it would avoid unnecessary echocardiograms that do not provide additional value.

Long-term use of tinzaparin for the treatment of cancer-associated thrombosis in clinical practice: Insights from the prospective TROPIQUE study.

BACKGROUND: Real word data on the efficacy and safety of long-term use of tinzaparin for the treatment of cancer-associated thrombosis (CAT) are scarce. METHODS: We performed a post-hoc analysis of all cancer patients included in the prospective multicenter observational TROPIQUE study who received long-term treatment with tinzaparin for a first venous thromboembolism (VTE) event. We evaluated the patterns of anticoagulant prescription, the adherence to clinical practice guidelines (CPGs) for the treatment of CAT, and the clinical outcomes within a 6-month follow-up. RESULTS: In total, 301 patients were included in this post-hoc analysis. At study entry, their mean age was 64.6±11.9years and 143 (47.5%) patients were men. The most frequent cancer type was gastrointestinal (23.9%), followed by breast (17.9%) and lung (15.3%) cancer. At time of VTE diagnosis, 164 (57.8%) patients had metastatic disease and 245 (81.42%) were receiving chemotherapy. Based on the aggregation of all study pre-defined criteria, tinzaparin prescription was fully compliant with CPGs in 219 (72.8%) patients. The mean effective treatment duration with tinzaparin was 6.07±0.17months. At 6-month follow-up, the cumulative incidence of recurrent VTE was 5.4% (95% CI: 3.2-9.2%) and the cumulative incidence of major bleeding was 5.8% (95% CI: 3.6-9.6%). Clinical outcomes tended to differ across different types of cancer. Death from any cause occurred in 102 (33.9%) patients, mainly related to cancer progression. CONCLUSIONS: This post-hoc analysis of TROPIQUE confirms the favorable benefit-risk ratio of tinzaparin for the long-term treatment of CAT.

High doses of systemic corticosteroids in patients hospitalised for exacerbation of chronic obstructive pulmonary disease. A cohort study. / Dosis altas de corticoides sistémicos en pacientes ingresados por exacerbación de enfermedad pulmonar obstructiva crónica. Un estudio de cohortes.

OBJECTIVES: To assess the effect of high doses of corticosteroids in patients hospitalised for exacerbation of chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS: A prospective cohort study was conducted on patients hospitalized with COPD between January and March 2015, grouped according to the glucocorticoid dosage administered (cutoff, 40mg of prednisone/day). We compared the results of hospital stay, readmission and mortality at 3 months of discharge. RESULTS: We analysed 87 patients. The median daily dose was 60mg of prednisone (interquartile range, 46.67-82.33mg/day), and the administration route was intravenous in 96.6% of the cases. We established a relative risk (RR) for hospital stays longer than 8 days of 1.095 (95% CI 0.597-2.007; P=.765) when steroid dosages greater than 40mg/day were employed. In these patients, the hazard ratio (HR) for readmission in the 3 months after discharge was 0.903 (95% CI 0.392-2.082; P=.811), and the mortality was 1.832 (95% CI 0.229-16.645; P=.568). Neither the RR nor the HR varied in a statistically significant manner after adjusting for confounding factors. CONCLUSIONS: A daily dose greater than 40mg of prednisone in patients hospitalised for COPD exacerbation was not associated with a shorter hospital stay or a reduction in readmissions or mortality at 3 months.

Target organ damage in acute heart failure.

Acute heart failure is a prognostic factor due to its high mortality during the acute phase and the increased frequency of medium to long-term adverse events. The pathophysiological mechanisms triggered during these exacerbations can persist after reaching clinical stability, remaining even after the acute episode has ended. A certain degree of neurohormonal activation, oxidative stress, apoptosis and inflammation (among other conditions) can therefore persist, resulting in organ damage, not just of the myocardium but likely the entire cardiovascular apparatus. This new insight into the persistence of harmful mechanisms that last beyond the exacerbations could be the start of a change in perspective for developing new therapeutic strategies that seek an overall control of hemodynamic and congestive changes that occur during acute decompensated heart failure and changes that remain after achieving clinical stability.

Persistence of müllerian derivatives, lymphangiectasis, hepatic failure, postaxial polydactyly, renal and craniofacial anomalies.

We describe 3 unrelated newborn males with a previously unreported constellation of congenital anomalies. All 3 died neonatally of hepatic failure. Clinically, they presented with a pattern of malformations characterized by prenatal linear growth deficiency, hypertrophied alveolar ridges, redundant nuchal skin, and postaxial polydactyly. All 3 cases had male external genitalia with cryptorchidism, and 2 of them, a small penis. Necropsies showed similar internal anomalies, consisting of müllerian duct remnants, lymphangiectasis, and renal anomalies. The karyotypes were normal (46, XY) in skin fibroblasts (Case 1) and in peripheral blood lymphocytes (Case 3). Although this pattern of congenital anomalies must be differentiated from several other lethal syndromes, to our knowledge, no similar cases have been described previously. Cause of this syndrome is unknown. Because Case 2 had a previous brother with similar anomalies, we suspect that this new entity probably is an autosomal recessive or X-linked trait.

[Comparison of mouth pressure, twitch, after anterior magnetic stimulation against posterior magnetic stimulation in healthy subjects]. / Comparación de la presión en boca, twitch, tras estimulación magnética anterior frente a estimulación magnética posterior en sujetos sanos.

BACKGROUND: If techniques for studying respiratory muscle function are easy to use and well tolerates by patients, they can be used routinely. Measuring mouth twitches (TwM) using either bilateral anterior or posterior magnetic stimulation meets both criteria. SUBJECTS AND METHODS: We studied 16 healthy subjects. TwM was measured using bilateral anterior (TwMA) and posterior (TwMP) stimulation. Ten stimuli were applied for each technique for each subject. Five subjects repeated the test was repeated on a different day. RESULTS: The mean TwMA in healthy subjects was 21.07 +/- 4.4 cmH2O (range 13.72-30.11); the mean TwMP was 21.12 +/- 5.9 cmH2O (range 12.7-35.7) (NS). The mean difference was 2.8 +/- 2.5 cmH2O, while the ratio TwMP/PImax was 0.15 (range 0.08-0.10) and TwMA/PImax was 0.14 (range 0.07-0.15). The correlation between the two technique was 0.8. The patients who underwent testing twice had a mean TwMA of 20 cmH2O on the first day and 10.18 cmH2O on the second (NS). The coefficient of variation (CoV%) was 5.9% for TwMA and 7.2% for TwMP. CONCLUSIONS: The two techniques for measuring TwM give similar results and coefficients of variation in healthy subjects; either technique can be used. Variation from one testing day to another is low.

[Mediastinal liposarcoma. A report of 2 cases]. / Liposarcoma mediastínico. A propósito de 2 casos.

Liposarcomas are malignant mesenchymal tumors whose primary location in the mediastinum is rare. We report two cases of mediastinal liposarcoma, describing the clinical signs and radiologic features found and the diagnostic procedures performed. The significance of histologic variability as a factor that conditions treatment and prognosis is underlined.

[Skin tumor as presentation form of lung actinomycosis]. / Tumoración cutánea como forma de presentación de la actinomicosis pulmonar.

We report three cases of thoracic actinomycosis whose symptoms were cutaneous tumors on the thorax. Clinical signs and images are described, along with diagnostic procedures. The excellent outcome after antibiotic treatment, which must last at least 6 months, is emphasized as well as the need to keep this disease in mind when certain symptoms and images coincide.

[Protected bacteriologic brushing in patients with severe copd]. / El cepillado protegido bacteriológico en pacientes con EPOC severa.

To determine the presence of germs and their concentration in a group of patients with severe chronic obstructive pulmonary disease (COPD) (FEV1 < 50%), some of whom were in stable condition and others of whom were in acute phase. Twenty-six patients with severe COPD (14 stable and 12 acute phase) were enrolled. None had received prior antibiotic or corticoid treatment. The stable patients had no signs or symptoms of exacerbation, whereas the acute-phase patients had increased dyspnea, sputum volume and purulence. The patients received aerosol rather than liquid anesthesia when PSB sampling was performed. A PSB finding was considered positive at a level > or = 10(3) CFU/ml. There were no significant differences between the groups with respect to age, sex, proportion of smokers and ex-smokers or packs per year. The only spirometric measure that was significantly different was (FEV1/FVC, which was lower in the acute-phase group (p < 0.05). Positive PSB findings were recorded for 57.1% of the stable patients and for 66.7% of the acute-phase patients (p = NS). H. influenzae was the microorganism found most often in both groups. The mean CFU/ml level was 8,625 in stable patients and 17,375 in acute-phase patients (p = NS). A large proportion of stable patients (57.1%) with severe COPD harbor significant concentrations of germs as revealed by PSB sampling. Germ concentrations were found in a non significantly greater number of acute-phase patients, confirming the lack of congruence between clinical status and bacteriological condition.

[Striated osteopathy with cranial sclerosis and macrocephaly in childhood. Report of 2 cases]. / Osteopatía estriada con esclerosis craneal y macrocefalia en la infancia. Aportación de dos casos.

INTRODUCTION: Osteopathia striata with cranial sclerosis (OS-CS) is a specific and rare bone dysplasia, with autosomal dominant inheritance. Radiographic features are typical: linear striations, particularly of long bones, and increased density mostly of the cranial basis. Facial impression is also typical, with frontal bossing, hypertelorism, epicanthic folds and both broad and depressed nasal bridge. Macrocephaly, usually present at birth, is likely to be the initial manifestation and has an uneventful course. CLINICAL CASES: Two girls, aged 3 years-5 months and 5 years-4 months with OS-CS and macrocephaly are reported here. They were evaluated from neonatal period for macrocephaly not complicated associated with peculiar facial appearance. At age of 3 years, radiologic examination showed linear striations of the long bones and sclerosis of the skull base. Their development were normal and no related deficiency was detected. Parents roentgenographs were normal. CONCLUSION: We conclude that OS-CS should be considered in the differential diagnosis in infants with macrocephaly without complications, specially if the facial appearance is striking.
