Anemia can predict organ failure in acute pancreatitis.

Acute pancreatitis (AP) is the leading hospital admission in Gastroenterology and has a variable clinical course. Identifying severity of AP patients in its early stages is of foremost importance to improve prognosis. The revised Atlanta Classification grades AP severity by the presence of organ failure and local complications.

Recurrent acute pancreatitis is not uncommon in our clinical setting.

Data on recurrent episodes of acute pancreatitis (RAP) are scarce. The aim of the study was to evaluate our rate of RAP and risks factors. This is a retrospective, single-center, study of consecutive patients admitted for AP and followed-up. Patients with more than one AP attack (RAP) were compared with patients with only a single AP episode (SAP) Clinical, demographic, outcome measures and severity were studied. 561 patients were included and follow-up over a mean 67.63 months' time. Our rate of RAP was 18,9%. Most patients suffered form only one episode of RAP (93%). Etiology of RAP episodes was mainly biliary (67%). On univariate analysis younger age (p 0.004), absence of high blood pressure (p 0.013) and absent of SIRS (p 0.022) were associated with recurrence of AP. On multivariate analysis only younger age was related to RAP (OR 1.015 95%IC 1.00-1.029). There were no statistical differences in outcome measures between both cohorts. RAP had a milder course in terms of severity (SAP 19% moderately severe/severe versus 9% in SAP). Almost 70% of the biliary RAP patients did not have a cholecystectomy performed. In this subset of patients, age OR 0.964 (95%IC 0.946-0.983), cholecystectomy OR 0.075 (95%IC 0.189-0.030) and cholecystectomy plus ERCP OR 0.190 (95%IC 0.219-0.055) were associated with absent of RAP. The rate of RAP in our series was 18,9%. Younger age was the only risk factor associated. Biliary etiology accounts for a large proportion of our RAP which could have been prevented with cholecystectomy or cholecystectomy plus ERCP.

Auditing completion of nursing records as an outcome indicator for identifying patients at risk of developing pressure ulcers, falling, and social vulnerability: An observational study.

AIM: To evaluate the completion of nursing records through scheduled audits to analyse risk outcome indicators. BACKGROUND: Nursing records support clinical decision-making and encourage continuity of care, hence the importance of auditing their completion in order to take corrective action where necessary. METHOD: This was an observational descriptive study carried out from February to November 2020 with a sample of 1131 electronic health records belonging to patients admitted to COVID-19 hospital units during three observation periods: pre-pandemic, first wave, and second wave. RESULTS: A significant reduction in nursing record completion rates was observed between pre-pandemic period and first and second waves: Braden scale 40.97%, 28.02%, and 30.99%; Downton scale: 43.74%, 22.34%, and 33.91%; Gijón scale: 40.12%, 26.23%, and 33.64% (p < 0.001). There was an increase in the number of records completed between the first and second waves following the measures adopted after the quality audit. CONCLUSIONS: The use of scheduled audits of nursing records as quality indicators facilitated the detection of areas for improvement, allowing timely corrective actions. IMPLICATIONS FOR NURSING MANAGEMENT: Support from nursing managers at health care facilities to implement quality assessment programmes encompassing audits of clinical record completion will encourage the adoption of measures for corrective action.

Anomalous self-experiences are related to general cognition deficits in schizophrenia.

Anomalous self-experiences (ASEs) are prevalent in schizophrenia, but its underpinnings are not completely understood. Given the likely complex substrate of the experience of the self, neurocognitive functions requiring coordinate cerebral activity may relate to ASEs. Moreover, cognitive deficits functioning may be involved in the link between self-experience disturbances and some aspects of social dysfunction in schizophrenia. We have assessed ASEs in 41 schizophrenia patients (11 first episodes) using the Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE), and the general cognition using the Brief Assessment of Cognition in Schizophrenia (BACS). Besides, social cognition was assessed using two complementary tools Meyer, Salovey and Caruso Emotional Intelligence Test (MSCEIT) and GEOPTE (Grupo Español para la Optimización del Tratamiento de la Esquizofrenia). The results revealed that Self-awareness/presence and Somatization IPASE scores were inversely explained by motor speed in the BACS; Consciousness IPASE scores were inversely explained by problem solving performance in the BACS. These data reveal a significant relationship between certain domains of general cognition and anomalous self-experiences, that may be useful in further investigation on the substrates of ASEs.

Assessment of radiation doses received by patients during endoscopic retrograde cholangiopancreatography according to disease location.

OBJECTIVE: patients are exposed to ionizing radiation during endoscopic retrograde cholangiopancreatography (ERCP). Radiation dose depends on multiple factors. The goal of this study was to assess fluoroscopy time (FT), radiation doses and effective dose (ED) during ERCP according to the condition being treated. MATERIALS AND METHODS: a descriptive study was performed of 369 consecutive ERCPs from January 2017 to June 2019. Patient demographic and procedure data were collected. FT, cumulative dose area product (DAP), fluoroscopy DAP, DA fluoroscopy, air kerma, and number of radiographs were assessed. ED was estimated using specific conversion factors. RESULTS: the mean age was 73.34 years and 193 subjects were male. Mean FT was 4.56 ± 0.17 min, cumulative DAP was 2,056.73 ± 188.83 cGycm2, fluoroscopy DAP was 1,722.90 ± 82.26 cGycm2 and air kerma was 85.84 ± 4.93 mGy. The number of radiographs was 2.10 ± 0.07 and the mean ED was 5.34 ± 0.49 mSv. FT was significantly longer for choledocholithiasis (CL), proximal malignant biliary stricture (PMBS) and distal malignant biliary stricture (DMBS) versus others (OT). Cumulative DAP was higher for PMBS (p < 0.002). FT, cumulative DAP, fluoroscopy DAP and air kerma values were significantly higher for complicated CL as compared to simple CL. ED was higher for CL, DMBS and PMBS, but only significantly (p < 0.002) for PMBS. CONCLUSIONS: FT for ERCP is variable and increases with exploration difficulty. Thus, it is longer in the case of PMBS, as well as with the amount of radiation received by the patients and ED.

Impact of radiological follow-up frequency on resected lung cancer: a propensity score matching analysis.

Background: Despite advances in lung cancer treatment and the subsequent improvement in oncological outcomes, the optimal frequency of radiological follow-up remains unclear. Current recommendations lack consensus and do not consider individual patient characteristics and tumor factors. This study aimed to examine the impact of radiological follow-up frequency on oncological outcomes following lung cancer resection. Methods: A prospective multicenter study, involving patients who underwent anatomical lung resection in the GEVATS database between December 2016 and March 2018. The relationship between surveillance frequency and oncological outcomes was evaluated. Two groups were established based on follow-up frequency: low frequency (LF) and high frequency (HF). Subgroup analyses were performed based on tumor stage, histology, lymphadenectomy, and adjuvant therapy. Propensity score matching (PSM) was applied to balance the groups. Results: A total of 1,916 patients were included in the study, LF 444 (23.17%), HF 1,472 (76.83%). Factors associated with HF surveillance included higher stage, adjuvant chemotherapy and adjuvant radiotherapy. Subanalyses were performed after PSM for various factors, revealing significant differences between LF and HF groups in cancer-specific survival among who received adjuvant therapy {LF 53.021 months [95% confidence interval (CI): 48.622-57.421] vs. HF 58.836 months (95% CI: 55.343-62.330); HR 0.453, 95% CI: 0.242-0.849; P=0.013}, as well as overall survival for patients with squamous cell carcinoma [LF 54.394 months (95% CI: 51.424-57.364) vs. HF 61.578 months (95% CI: 59.091-64.065); HR 0.491, 95% CI: 0.299-0.806; P=0.005] and those who received adjuvant therapy LF 50.176 months [95% CI: 45.609-54.742) vs. HF 57.189 months (95% CI: 53.599-60.778); HR 0.503, 95% CI: 0.293-0.865; P=0.013]. Conclusions: Findings suggest that high-frequency surveillance only improves survival outcomes in lung cancer patients who received adjuvant treatment or had squamous cell carcinoma. Therefore, future guidelines for lung cancer follow-up should consider individualizing the frequency of radiological surveillance based on patients' risk profiles.

Postoperative delirium: An independent risk factor for poorer quality of life with long-term cognitive and functional decline after cardiac surgery.

STUDY OBJECTIVE: To evaluate the influence of delirium on the functional and cognitive capacity of patients included in the DELIPRECAS study, as well as on their quality of life, in the 3-4 years after cardiac surgery. DESIGN: Prospective observational study. SETTING: Assessment of cognitive and functional status from hospital discharge to the present, 3 years after cardiac surgery. PATIENTS: 313 patients undergoing cardiac surgery consecutively, aged 18 years or over. MEASUREMENTS: The primary outcome measure was the cognitive and functional status of the patients 3 years after cardiac surgery, evaluated by telephone interview, and the possible influence on them of delirium diagnosed by the Confusion Assessment Method in Intensive Care Units (CAM-ICU) during their stay in the intensive care unit after cardiac surgery. MAIN RESULTS: Postoperative delirium acts as an independent risk factor for the long-term development of memory problems (OR 6.11, 95% CI 2.54 to 14.68, p < 0.001), concentration (OR 11.20, 95% CI 3.58 to 35.09, p > 0.001), confusion/disorientation (OR 10.93, 95% CI 3.61 to 33.12, p > 0.001), sleep problems (OR 5.21, 95% CI 2 0.29 to 11.84, p < 0.001), nightmares (OR 8.99, 95% CI 1.98 to 40.90, p = 0.004), emotional problems (OR 4.30, 95% CI 1.87 to 9.91, p = 0.001) and poorer mobility after hospital discharge (OR 2.436, 95% CI 1.06 to 5.61, p = 0.037). The number of hospital readmissions was also significantly higher in those patients who developed delirium after cardiac surgery (27% vs 13.8%, p = 0.022). CONCLUSION: Postoperative delirium is a risk factor for decreased quality of life in patients 3 years after heart surgery, being associated with greater cognitive and functional deterioration, as well as greater risk of hospital readmission. Therefore, emphasis should be placed on both prevention and early recognition and treatment of delirium to improve long-term outcomes for patients after cardiac surgery.

Testicular cancer: our experience after 10 years.

OBJECTIVES: Testicular cancer represents about 1% of malignant tumors in men. Of these tumors 95% are germ cell tumors (GCTs), which have a maximum incidence between the second and third decades of life. Our objective was to carry out a retrospective analysis of testicular tumor cases that had been diagnosed in our Health Area between the years 2000 and 2010. METHODS: We performed a retrospective descriptive study between the years 2000 and 2010 analyzing 43 patients treated for testicular cancer, including in the analysis tumor incidence, the patient's age, clinic attended, patient's time until appointment, presence of tumor markers, patient's time before treatment, use of testicular prostheses, histological type and their typical characteristics, oncological treatment, tumor progression and mortality rate. RESULTS: We found an incidence of 4-5 cases/100,000 population/year in our Health Area. Two-thirds of the cases were detected in Stage I, and 100% of these cases showed complete remission. Among those with higher stage tumors, two out of three patients were cured after chemotherapy. For the remaining one-third, rescue treatments managed to achieve a remission rate of 66%. Mortality was low and was linked to lymphoma or metastatic dissemination. CONCLUSION: The trend towards early diagnosis with detection during the initial cancer stages, together with current chemotherapy protocols, enables a high cure rate for testicular cancer. Mortality in our series was associated with primary or secondary lymphomas.

Impact of Oxygen Delivery on the Development of Acute Kidney Injury in Patients Undergoing Valve Heart Surgery.

One of the strongest risk factors for death in individuals undergoing cardiac surgery is Cardiac Surgery Associated-Acute Kidney Injury (CSA-AKI). Although the minimum kidney oxygen delivery index (DO2i) during cardiopulmonary bypass (CPB) has been reported, the optimal threshold value has not yet been established. A prospective study was conducted from June 2012 to January 2016 to asses how DO2i influences the pathogenesis of CSA-AKI, as well as its most favorable cut-off value. DO2 levels were recorded at the beginning, middle, and end of the CPB. The association between DO2i and CSA-AKI was investigated using multivariable logistic regression analysis. The optimal cut-off of DO2i as a predictor of CSA-AKI was determined using Classification and Regression Tree (CART) analysis. A total of 782 consecutive patients were enrolled. Of these, 231 (29.5%) patients developed AKI. Optimal DO2i thresholds of 303 mL/min/m2 during the CPB and 295 mL/min/m2 at the end of the intervention were identified, which increased the odds of CSA-AKI almost two-fold (Odds Ratio (OR), 1.90; 95% CI, 1.12-3.24) during the surgery and maintained that risk (OR 1.94; 95% CI, 1.15-3.29) until the end. Low DO2i during cardiopulmonary bypass is a risk factor for CSA-AKI that cannot be ruled out. Continuous renal oxygen supply monitoring for adult patients could be a promising method for predicting AKI during CPB.

The influence of preoperative anxiety on postoperative pain in patients undergoing cardiac surgery.

Patients undergoing cardiac surgery represent a challenge in terms of pain management due to multiple factors relating to the patients and to the procedure itself. Our aim was to identify the influence of levels of preoperative anxiety on postoperative pain in patients undergoing cardiac surgery and explore associations between preoperative anxiety, postoperative pain, analgesic requirements, and sex. We present a prospective cohort study of 116 patients undergoing cardiac surgery between January and April 2020. Preoperative anxiety was evaluated using the State-Trait Anxiety Inventory and the amount of morphine needed to keep pain intensity below 4 on the verbal numerical rating scale was recorded for 48 h post-surgery. Given the extracorporeal circulation time, type of surgery and body surface, it was observed that every percentile increase in preoperative state anxiety led to an extra 0.068 mg of morphine being administered. For each extra year of age, the amount of morphine needed decreased by 0.26 mg, no difference was observed between men and women in terms of preoperative anxiety or postoperative analgesics requirements. It may be concluded that in cardiac surgery, postoperative analgesic requirements increased with higher levels of preoperative state anxiety and decreased for every extra year of age.

Long-term results of visual function in posterior uveal melanoma patients treated with I125 episcleral brachytherapy in a Spanish referral Ocular Oncology Unit.

PURPOSES: We analyzed patient, tumor and dosimetric characteristics of subjects in a Spanish population diagnosed with uveal melanoma treated with iodine 125 (I125) episcleral brachytherapy, who presented with post-treatment loss of useful visual acuity and global evolution of visual acuity. METHODS: A single historic observational cohort study was undertaken. Patients with uveal melanoma were recruited between September 1995 and June 2015. Clinical, tumor and dosimetric data collection and visual acuity evaluations were performed under everyday practice conditions based on a useful visual acuity >0.1 on the decimal scale. The baseline analysis was performed using descriptive and survival analyses according to Kaplan-Meier curves. RESULTS: A total of 286 of the 665 patients diagnosed with uveal melanoma received episcleral brachytherapy, and 198 were included in the study. The mean follow-up time was 75.3 months (95% CI = 68.0-82.6). Patients with post-treatment useful visual acuity loss (n=94, 47%) presented the following characteristics: visual symptoms (n=80, p-value = 0.001); iris color (brown n=33, hazel green n=49, p-value = 0.047); Collaborative Ocular Melanoma Study size (medium n=80, p-value = 0.159); tumor, node, metastasis stage (T2: n=38, T3: n=38, p=0.012); shape (nodular n=67, mushroom-shaped n=26, p=0.001); posterior pole involvement (n=47, p=0.04); recurrence (n=10, p=0.001); and dose administered in the fovea, optic nerve and center of the eye (p<0.002). Using Kaplan-Meier analysis, the mean overall survival of useful visual acuity was 90.19 months, and the probability of preserving useful visual acuity was 66% for one year, 45% for five years and 33% for ten years. CONCLUSION: Patients most likely to present with visual acuity loss were those with the following profile: elderly males with dark irises who were diagnosed with visual symptoms and exhibited a medium/large melanoma with a mushroom shape in the posterior pole (near the fovea and/or optic nerve). All patients treated with episcleral brachytherapy are likely to present with visual acuity loss, which is more pronounced in the first few years following treatment.

The Impact of COVID-19 on Levels of Adherence to the Completion of Nursing Records for Inpatients in Isolation.

The COVID-19 pandemic has led to an increased workload for nurses and organisational and structural changes, which have been necessary to meet the needs of inpatients in isolation. AIM: To describe the impact of the COVID-19 pandemic on levels of adherence to the completion of nursing records that document the risk of developing pressure ulcers, falling, and social vulnerability among hospitalised patients in isolation. METHODS: Observational pre-post comparison study. Comparison between nursing records (the Braden, Downton, and Gijón scales) belonging to 1205 inpatients took place in two phases. Phase 1: 568 patients admitted in February 2020, prior to the COVID-19 pandemic, vs. phase 2: 637 patients hospitalised with COVID-19 in March-April 2020, during the peak of the first wave of the pandemic. This research adheres to the STROBE guidelines for the reporting of observational studies. RESULTS: The degree of completion of the Braden, Downton, and Gijón scales decreased significantly in phase 2 vs. phase 1 (p < 0.001). The mean Downton and Gijón scale scores for patients admitted in phase 1 were higher compared to those of patients admitted in phase 2 (p < 0.001). The mean Braden scale score in phase 2 was higher than in phase 1 (p < 0.05). CONCLUSION: During the COVID-19 pandemic, there was a decrease in the completion of nursing records in the clinical records of patients in isolation. The levels of risk of developing PUs, falling, and social vulnerability of patients admitted to hospital were lower during the first wave of the pandemic.

Parental Satisfaction With Autonomous Pediatric Ambulatory Surgery Units.

BACKGROUND AND OBJECTIVES: Ambulatory surgery is much favored in children, as they are usually healthy with no major comorbidities. Obvious benefits are minimization of health costs, optimal utilization of resources, decreased exposure to infections, and psychological and emotional advantages of avoiding admission of the patient, especially for the family. Parental satisfaction is a challenge in pediatric surgery processes. The objective of this study was to compare satisfaction in parents whose children underwent surgery without overnight stays with parents whose children were operated on in an autonomous major ambulatory surgery unit (hospital isolated). METHODS: This was a prospective observational study of 200 children who received surgery on an outpatient basis (133 were included in an outpatient unit and 67 in a hospital setting). Different variables were collected, including sex, age, type of surgery, and length of stay in the hospital and location, and a telephone perception survey was conducted (questionnaire of satisfaction of 14 questions with possible answers from 1 to 4 on a Likert scale and a 15th question on global satisfaction, with an answer from 0 to 10). RESULTS: Overall satisfaction during the hospital stay was higher in the group operated on in the autonomous major surgery unit (3.54 ± 0.57 vs 3.28 ± 0.64, P = .004). Whether parents respond as being very satisfied with the hospital stay is influenced by several factors, among which are: being treated at major ambulatory surgery units (odds ratio [OR] = 2.16), good or very good information received prior to surgery (OR = 2.03), and good or very good information received at discharge (OR = 2.48). CONCLUSIONS: Parents of children who received surgery on an outpatient basis were more satisfied if the procedure was performed in an autonomous major ambulatory surgery unit compared with hospitalization, even if it was not overnight. The information received during the care process influenced the parents' satisfaction. These findings suggest that efforts should be devoted to the creation of autonomous units for ambulatory surgery and to the improvement of perioperative information.

Development and validation of a delirium risk prediction preoperative model for cardiac surgery patients (DELIPRECAS): An observational multicentre study.

STUDY OBJECTIVE: To develop and validate a delirium risk prediction preoperative model for patients undergoing cardiac surgery. DESIGN: Observational prospective multicentre study. SETTING: Six intensive care units in Spain. PATIENTS: 689 patients undergoing cardiac surgery consecutively, aged ≥18 years. MEASUREMENTS: The primary outcome measure was the development of delirium, diagnosed using the Confusion Assessment Method in Intensive Care Units (CAM-ICU), during the stay in the intensive care unit after cardiac surgery. MAIN RESULTS: The model was developed with 345 consecutive patients undergoing cardiac surgery at six hospitals and validated with another 344 patients from the same hospitals. The prediction model contained four preoperative risk factors: age over 65 years, Mini-Mental State Examination (MMSE) score of 25-26 points (possible impairment of cognitive function) or < 25 (impairment of cognitive function), insomnia needing medical treatment and low physical activity (walk less than 30 min a day). The model had an area under the receiver operating characteristics curve of 0.825 (95% confidence interval: 0.76-0.89). The validation resulted in an area under the curve of 0.79 (0.73-0.85) and the pooled area under the receiver operating characteristics curve (n = 689) was 0.81 (0.76-0.85). We stratified patients in groups of low (0%-20%), moderate (> 20%-40%), high (> 40%-60%) and very high (> 60%) risk of developing delirium, with a positive and negative predictive value for the very high risk group of 70.97% and 85.56%, respectively. CONCLUSION: The DELIPRECAS model (DELIrium PREvention CArdiac Surgery), consisting of four well-defined clinical risk factors, can predict in the preoperative period the risk of developing postoperative delirium in patients undergoing cardiac surgery. An automatic version of the risk calculator is available.

HGF, IL-1α, and IL-27 Are Robust Biomarkers in Early Severity Stratification of COVID-19 Patients.

Pneumonia is the leading cause of hospital admission and mortality in coronavirus disease 2019 (COVID-19). We aimed to identify the cytokines responsible for lung damage and mortality. We prospectively recruited 108 COVID-19 patients between March and April 2020 and divided them into four groups according to the severity of respiratory symptoms. Twenty-eight healthy volunteers were used for normalization of the results. Multiple cytokines showed statistically significant differences between mild and critical patients. High HGF levels were associated with the critical group (OR = 3.51; p < 0.001; 95%CI = 1.95-6.33). Moreover, high IL-1α (OR = 1.36; p = 0.01; 95%CI = 1.07-1.73) and low IL-27 (OR = 0.58; p < 0.005; 95%CI = 0.39-0.85) greatly increased the risk of ending up in the severe group. This model was especially sensitive in order to predict critical status (AUC = 0.794; specificity = 69.74%; sensitivity = 81.25%). Furthermore, high levels of HGF and IL-1α showed significant results in the survival analysis (p = 0.033 and p = 0.011, respectively). HGF, IL-1α, and IL 27 at hospital admission were strongly associated with severe/critical COVID-19 patients and therefore are excellent predictors of bad prognosis. HGF and IL-1α were also mortality biomarkers.

Can the Cytokine Profile According to ABO Blood Groups Be Related to Worse Outcome in COVID-19 Patients? Yes, They Can.

Severe status of coronavirus disease 2019 (COVID-19) is extremely associated to cytokine release. Moreover, it has been suggested that blood group is also associated with the prevalence and severity of this disease. However, the relationship between the cytokine profile and blood group remains unclear in COVID-19 patients. In this sense, we prospectively recruited 108 COVID-19 patients between March and April 2020 and divided according to ABO blood group. For the analysis of 45 cytokines, plasma samples were collected in the time of admission to hospital ward or intensive care unit and at the sixth day after hospital admission. The results show that there was a risk of more than two times lower of mechanical ventilation or death in patients with blood group O (log rank: p = 0.042). At first time, all statistically significant cytokine levels, except from hepatocyte growth factor, were higher in O blood group patients meanwhile the second time showed a significant drop, between 20% and 40%. In contrast, A/B/AB group presented a maintenance of cytokine levels during time. Hepatocyte growth factor showed a significant association with intubation or mortality risk in non-O blood group patients (OR: 4.229, 95% CI (2.064-8.665), p < 0.001) and also was the only one bad prognosis biomarker in O blood group patients (OR: 8.852, 95% CI (1.540-50.878), p = 0.015). Therefore, higher cytokine levels in O blood group are associated with a better outcome than A/B/AB group in COVID-19 patients.

National Temporal Trend Analysis of Infective Endocarditis among Patients Infected with HIV in Spain (1997-2014): A Retrospective Study.

BACKGROUND: People living with human immunodeficiency virus (HIV) (PLWH) form a vulnerable population for the onset of infective endocarditis (IE). We aimed to analyze the epidemiological trend of IE, as well as its microbiological characteristics, in PLWH during the combined antiretroviral therapy era in Spain. METHODS: We performed a retrospective study (1997-2014) in PLWH with data obtained from the Spanish Minimum Basic Data Set. We selected 1800 hospital admissions with an IE diagnosis, which corresponded to 1439 patients. RESULTS: We found significant downward trends in the periods 1997-1999 and 2008-2014 in the rate of hospital admissions with an IE diagnosis (from 21.8 to 3.8 events per 10,000 patients/year; p < 0.001), IE incidence (from 18.2 to 2.9 events per 10,000 patients/year; p < 0.001), and IE mortality (from 23.9 to 5.5 deaths per 100,000 patient-years; p < 0.001). The most frequent microorganisms involved were staphylococci (50%; 42.7% Staphylococcus aureus and 7.3% coagulase-negative staphylococci (CoNS)), followed by streptococci (9.3%), Gram-negative bacilli (8.3%), enterococci (3%), and fungus (1.4%). During the study period, we found a downward trend in the rates of CoNS (p < 0.001) and an upward trends in streptococci (p = 0.001), Gram-negative bacilli (p < 0.001), enterococci (p = 0.003), and fungus (p < 0.001) related to IE, mainly in 2008-2014. The rate of community-acquired IE showed a significant upward trend (p = 0.001), while the rate of health care-associated IE showed a significant downward trend (p < 0.001). CONCLUSIONS: The rates of hospital admissions, incidence, and mortality related to IE diagnosis in PLWH in Spain decreased from 1997 to 2014, while other changes in clinical characteristics, mode of acquisition, and pathogens occurred over this time.

[Antenatal corticosteroids and incidence of neonatal respiratory distress after elective caesarean section in late preterm and term neonates]. / Corticoides antenatales e incidencia de distrés respiratorio del recién nacido en las cesáreas programadas del pretérmino tardío y término precoz.

INTRODUCTION: Birth by elective caesarean section in late preterm and early term newborn increases the risk of respiratory distress. Administration of antenatal corticosteroids in these cases could reduce the respiratory distress and its severity. OBJECTIVES: To determine the influence of antenatal corticosteroids use in elective caesarean sections in the respiratory distress of the newborn from 35+0 to 38+6 weeks of gestational age. PATIENTS AND METHODS: Retrospective analytical study of caesarean sections from 35+0 to 38+6 gestational age was conducted in a tertiary hospital from January 2013 to April 2017. Data were collected from medical records of pregnant women and newborns after an implementation of new protocol of betamethasone administration to these elective caesarean sections. Analysis was performed on 2newborn subgroups: preterm newborn (PTN) 35-36 gestational age and term (TN) 37-38 weeks. RESULTS: A total of 208 elective caesarean sections were performed in the study period. Corticosteroids were administered in 97 (46.6%) of cases. The percentage of respiratory distress was higher in the group of preterm newborn compared to term newborn (29% vs. 8.8%, P<.001) and in term newborn higher at a lower gestational age. Between treated with corticosteroids or not, no significant differences were found in the treated and non-treated in the development of respiratory distress (PTN 30 vs. 30%, TN 9.1 vs. 6.9%, P=.6). CONCLUSIONS: No statistically significant differences were found in this study in favour of the administration of an antenatal dose of betamethasone in the reduction of respiratory distress in the elective caesarean sections from 35+0 to 38+6 gestational age. The delay in the indication of elective caesarean sections, whenever possible, could help reduce the incidence of newborn respiratory distress.

Revisión sistemática sobre la influencia de la edad, el género y las variaciones estacionales en el absceso periamigdalino / Systematic review on the influence of age, gender and seasonal variations on peritonsillar abscess

Introducción y objetivo: El absceso periamigdalino (AP) es la complicación más frecuente de la amigdalitis aguda. Dadas las discrepancias observadas en la literatura, presentamos una revisión sistemática de la bibliografía, para analizar la prevalencia del AP en nuestro ámbito, en relación con tres factores epidemiológicos: la edad, el sexo y la climatología. Método: Se realizó una búsqueda bibliográfica sobre la influencia de la edad, el género y la estacionalidad en el AP. Las bases utilizadas fueron PubMed, Cochrane y Medline, sin restricción de tiempo, siguiendo la metodología PRISMA. El registro se llevó a cabo por tres revisores independientes, durante el mes de octubre de 2022. Resultados: Se obtuvieron, tras excluir duplicados, 289 artículos, de los que tras el cribado que se detalla en la metodología, seleccionamos 23, como parte de la revisión sistemática. Discusión: En la mayoría de los trabajos incluidos, se objetiva un predominio del AP en los hombres, con una ratio hombres/mujeres, variable de 1,16 a 3. Se desconocen las causas de esta diferencia de género. La edad media de aparición del AP varía, según el estudio, de los 22 a los 39 años. Aunque con resultados dispares, el AP no parece tener un predominio estacional, sin que podamos descartar una cierta influencia climática. Conclusiones: El AP es la complicación más frecuente de la amigdalitis aguda. En el adulto, predomina en hombres. La media de edad oscila entre los 22 y 39 años. No parece mostrar preferencia climática. (AU)

Introduction and objective: Peritonsillar abscess (PA) is the most frequent complication of acute tonsillitis. Given the discrepancies observed in the literature, we present a systematic review to analyse the prevalence of PA in our setting in relation to three epidemiological factors: age, gender, and climatology. Methods: A literature search was carried out on the influence of age, gender, and seasonality on PA. The databases used were PubMed, Cochrane, and Medline, without time restriction, following the PRISMA methodology. The registry was carried out by three independent reviewers during the month of October 2022. Results: After excluding duplicates, 289 articles were obtained, of which, after the screening detailed in the methodology, we selected 23 as part of the systematic review. Discussion: In most of the included papers, a predominance of PA in men is observed, with a male/female ratio varying from 1.16 to 3. The mean age of onset of PA varies, depending on the study, from 22 to 39 years. Although with disparate results, AP does not seem to have a seasonal predominance, without being able to rule out a certain climatic influence. Conclusions: AP is the most frequent complication of acute tonsillitis. In adults, it predominates in men. The mean age ranges between 22 and 39 years. It does not seem to show climatic preference.
