Impact of Delusions and Hallucinations on Clinical Insight Dimensions in Schizophrenia Spectrum Disorders.

INTRODUCTION: Insight in psychosis has been conceptualized as a continuous, dynamic, and multidimensional phenomenon. This study aims to determine the impact of delusions and hallucinations in different dimensions of clinical insight in schizophrenia spectrum disorders. METHODS: Cross-sectional multicenter study including 516 patients (336 men) diagnosed with schizophrenia spectrum disorders. Based on dichotomized scores of Positive and Negative Syndrome Scale (PANSS) items P1 (delusions) and P3 (hallucinations), patients were assigned to four groups according to current clear presence of delusions (scores 4 or above 4 in PANSS item P1) and/or hallucinations (scores 4 or above 4 in PANNS item P3). Insight was assessed using the three main dimensions of the Scale of Unawareness of Mental Disorder (SUMD). RESULTS: Around 40% of patients showed unawareness of illness; 30% unawareness of the need for treatment; and 45% unawareness of the social consequences of the disorder. Patients with current clear presence of delusions had higher overall lack of awareness, regardless of current clear presence of hallucinations. Similarly, the clear presence of delusions showed a greater predictive value on insight than the presence of hallucinations, although the implication of both in the prediction was modest. CONCLUSIONS: Our results confirm that lack of insight is highly prevalent in schizophrenia spectrum disorders, particularly when patients experience delusions. This study adds insight-related data to the growing symptom-based research, where specific types of psychotic experiences such as hallucinations and delusions could form different psychopathological patterns, linking the phenomenology of delusions to a lack of clinical insight.

The Frequency of Specific KRAS Mutations, and Their Impact on Treatment Choice and Survival, in Patients With Metastatic Colorectal Cancer.

BACKGROUND: Patients with metastatic colorectal cancer (mCRC) and KRAS mutations have a poor prognosis, seemingly dependent on the location of the mutation. This multicenter, retrospective, cohort study assessed the frequency and prognostic value of specific KRAS mutation codon locations in mCRC patients, and survival outcomes in relation to treatment. MATERIALS AND METHODS: Data from mCRC patients treated in 10 Spanish hospitals between January 2011 and December 2015 were analyzed. The main objective was to investigate (1) the impact of KRAS mutation location on overall survival (OS), and (2) the effect of targeted treatment plus metastasectomy and primary tumor location on OS in patients with KRAS mutations. RESULTS: The KRAS mutation location was known for 337/2002 patients. Of these, 177 patients received chemotherapy only, 155 received bevacizumab plus chemotherapy, and 5 received anti-epidermal growth factor receptor therapy plus chemotherapy; 94 patients underwent surgery. The most frequent KRAS mutation locations were G12A (33.8%), G12D (21.4%), and G12V (21.4%). Compared with other locations, patients with a G12S mutation had the shortest median OS (10.3 [95% CI, 2.5-18.0] months). OS was longer in patients who underwent surgery versus those who did not, with a trend toward prolonged survival with bevacizumab (median OS 26.7 [95% CI, 21.8-31.7] months) versus chemotherapy alone (median OS 23.2 [95% CI, 19.4-27.0] months). CONCLUSION: These findings confirm that KRAS mutation location may predict survival outcomes in patients with mCRC, and suggest that pre-/post-operative bevacizumab plus metastasectomy provides survival benefits in patients with KRAS mutations.

The Effects of Accompaniment on Maternal Anxiety During Elective Cesarean Delivery: A Quasi-experimental Study.

BACKGROUND: In Spain, allowing women to be accompanied by their partners during cesarean deliveries is a poorly consolidated practice. Going through this experience alone, not only deprives women from the opportunity of sharing the birth with their partners, but also, forces them to face, on their own, one of the most stressful experiences during pregnancy. OBJECTIVE: To analyze whether significant differences exist in levels of anxiety of women who receive an elective cesarean delivery, according to whether they are allowed to be accompanied by their partners. DESIGN: Quasi-experimental, longitudinal, prospective study, comparing a group of 31 women receiving elective cesarean deliveries, without the presence of their partners, with a group of 33 women with elective cesarean deliveries who were accompanied by their partners. Anxiety levels were assessed using the STAI-State/Trait scale. Participants were given a questionnaire to assess their level of satisfaction with the care received. RESULTS: Anxiety measured via total scores on the STAI-S scale was significantly lower (p < 0.004) among the women who were accompanied by their partners during the elective cesarean delivery (median = 25), compared to the group who were not (median = 50). The differences were also significant (p < 0.003) considering the impact of accompaniment upon the group with high scores in the STAI-S (> 31) and continue to be significant when using the cut-off point of very high scores on the STAI-S (> 45). CONCLUSIONS: Presence of partners during elective cesareans is a key factor for decreasing the anxiety caused by the surgery and for improving the overall experience of cesarean deliveries.

What is already known on this subject? Cesarean deliveries are one of the most stressful life experiences. Allowing women to be accompanied by their partners during cesarean deliveries is a poorly consolidated practice in some countries. Otherwise relevant international institutions recommend allowing an accompanying adult, present with the mother in the operating room during the entire process.What this study adds? Presence of partners during elective cesareans is a key factor for decreasing deliveries' anxiety, improving the overall experience, but it needs a mentality change in the obstetric and surgical team. These results could change the services organization in a more humane delivery, with overall positive impact in the patients' care.

Efficacy of Low-Dose versus High-Dose Continuous Cyclic Azithromycin Therapy for Preventing Acute Exacerbations of COPD.

BACKGROUND: Long-term azithromycin therapy significantly reduces the frequency of COPD exacerbations (ECOPD). However, previous studies have used different dosing regimens, and the efficacy of these regimens has not been compared. OBJECTIVE: Compare the efficacy of low-dose with high-dose continuous cyclic azithromycin (CC-A) in severe COPD. METHODS: Patients with severe COPD and repeated exacerbations (ECOPD ≥4 or ≥3 with at least 1 hospital admission in the previous year) were prospectively recruited (January 2017 to December 2019) as a multicenter cohort (from 3 university hospitals in the Barcelona area) and treated with low-dose CC-A: 250 mg 3 times per week (250-CC-A group). This cohort was compared with a historical (January 2007 to December 2013) single-center cohort of severe COPD with frequent ECOPD treated with high-dose CC-A: 500 mg 3 times per week (500-CC-A group). To assess differences in ECOPD prevention according to the administration of low-dose or high-dose CC-A, moderate-to-severe ECOPD was evaluated during the 12-month period before and after starting CC-A therapy. RESULTS: Fifty-eight patients with severe COPD were evaluated: 37 in the low-dose group and 21 in the high-dose group. The 250-CC-A therapy group achieved a mean reduction in moderate-to-severe ECOPD of 65.6% at 12 months after starting CC-A therapy (with a 61.5% reduction in hospitalizations), while the 500-CC-A group achieved a reduction of 60.5% (with a 44.8% reduction in hospitalizations). No significant differences between 250-CC-A and 500-CC-A dosages were observed in the mean annual reduction of moderate-to-severe ECOPD (p = 0.55) or hospitalizations (p = 0.07) with respect to the year prior to starting CC-A. CONCLUSIONS: Low-dose 250-CC-A therapy over a 1-year period is similar to high-dose 500-CC-A in reducing exacerbation frequency in severe COPD patients with frequent ECOPD despite maximal medical therapy.

Volume Infusion Markedly Increases Femoral dP/dtmax in Fluid-Responsive Patients Only.

OBJECTIVES: To evaluate the preload dependence of femoral maximal change in pressure over time (dP/dtmax) during volume expansion in preload dependent and independent critically ill patients. DESIGN: Retrospective database analysis. SETTING: Two adult polyvalent ICUs. PATIENTS: Twenty-five critically ill patients with acute circulatory failure. INTERVENTIONS: Thirty-five fluid infusions of 500 mL normal saline. MEASUREMENTS AND MAIN RESULTS: Changes in femoral dP/dtmax, systolic, diastolic, and pulse femoral arterial pressure were obtained from the pressure waveform analysis using the PiCCO2 system (Pulsion Medical Systems, Feldkirchen, Germany). Stroke volume index was obtained by transpulmonary thermodilution. Statistical analysis was performed comparing results before and after volume expansion and according to the presence or absence of preload dependence (increases in stroke volume index ≥ 15%). Femoral dP/dtmax increased by 46% after fluid infusion in preload-dependent cases (mean change = 510.6 mm Hg·s; p = 0.005) and remained stable in preload-independent ones (mean change = 49.2 mm Hg·s; p = 0.114). Fluid-induced changes in femoral dP/dtmax correlated with fluid-induced changes in stroke volume index in preload-dependent cases (r = 0.618; p = 0.032), but not in preload-independent ones. Femoral dP/dtmax strongly correlated with pulse and systolic arterial pressures and with total arterial stiffness, regardless of the preload dependence status (r > 0.9 and p < 0.001 in all cases). CONCLUSIONS: Femoral dP/dtmax increased with volume expansion in case of preload dependence but not in case of preload independence and was strongly related to pulse pressure and total arterial stiffness regardless of preload dependence status. Therefore, femoral dP/dtmax is not a load-independent marker of left ventricular contractility and should be not used to track contractility in critically ill patients.

Prediction of advanced colonic neoplasm in symptomatic patients: a scoring system to prioritize colonoscopy (COLONOFIT study).

BACKGROUND: Fast-track colonoscopy to detect patients with colorectal cancer based on high-risk symptoms is associated with low sensitivity and specificity. The aim was to derive a predictive score of advanced colonic neoplasia in symptomatic patients in fast-track programs. METHODS: All patients referred for fast-track colonoscopy were evaluated. Faecal immunological haemoglobin test (3 samples; positive> 4 µg Hb/g), and a survey to register clinical variables of interest were performed. Colorectal cancer and advanced adenoma were considered as advanced colonic neoplasia. A sample size of 600 and 500 individuals were calculated for each phase 1 and phase 2 of the study, respectively (Phase 1, derivation and Phase 2, validation cohort). A Bayesian logistic regression analysis was used to derive a predictive score. RESULTS: 1495 patients were included. Age (OR, 21), maximum faecal-Hb value (OR, 2.3), and number of positive samples (OR, 28) presented the highest ORs predictive of advanced colonic neoplasia. The additional significant predictive variables adjusted for age and faecal-Hb variables in Phase 1 were previous colonoscopy (last 5 years) and smoking (no, ex/active). With these variables a predictive score of advanced colonic neoplasia was derived. Applied to Phase 2, patients with a Score > 20 had an advanced colonic neoplasia probability of 66% (colorectal cancer, 32%), while those with a Score ≤ 10, a probability of 10% (colorectal cancer, 1%). Prioritizing patients with Score > 10, 49.4% of patients would be referred for fast-track colonoscopy, diagnosing 98.3% of colorectal cancers and 77% of advanced adenomas. CONCLUSIONS: A scoring system was derived and validated to prioritize fast-track colonoscopies according to risk, which was efficient, simple, and robust.

Parallel vessels as a predictor of benignity in solid breast masses.

To evaluate the presence of a parallel artery and vein on color Doppler ultrasound as a predictor of benignity in solid breast masses. This prospective study included all patients with solid breast masses identified by ultrasound at our center from January 2012 through December 2015. All masses were studied with B mode and color Doppler ultrasound. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value, and their respective 95% confidence intervals for the parallel vessel sign against the histologic findings or 2 years' follow-up without changes. A total of 526 solid masses were included in the 3-year period; the parallel vessel sign was observed in 377 (71.6%). We found 74.8% (95% CI: 70.9-78.7) sensitivity, 65% (95% CI: 50.2-79.7) specificity, 96.2% (95% CI: 94.3-98.1) positive predictive value, and 17.5% (95% CI: 11.4-23.6) negative predictive value. Of the 379 masses classified as breast imaging reporting and data system (BI-RADS) 3, the parallel vessel sign was observed in 275 (72.5%); all of these were definitively benign. Of the 109 masses classified as BI-RADS 4, the parallel vessel sign was observed in 89 (80.7%); 88 (98.8%) of these were definitively benign. Of the 38 masses classified as BI-RADS 5, the parallel vessel sign was observed in 13 (34.2%); all of these were definitively malignant. The parallel artery and vein sign is a good predictor of benignity, although it must be analyzed together with other morphologic descriptors.

Nursing workload and compliance with non-pharmacological measures to prevent ventilator-associated pneumonia: a multicentre study.

BACKGROUND: Ventilator-associated pneumonia is common and associated with high mortality. Nurses play a fundamental role in preventing ventilator-associated pneumonia. Evidence-based guidelines and training interventions about preventing ventilator-associated pneumonia do not ensure compliance with recommendations. AIMS AND OBJECTIVE: To evaluate the impact of nursing workload on compliance with non-pharmacological measures to prevent ventilator-associated pneumonia. DESIGN: A prospective observational study in two medical-surgical adult ICUs in Spain. METHODS: We measured nurses' knowledge about preventing ventilator-associated pneumonia through a questionnaire and workload, categorized with the Nine Equivalents of Nursing Manpower Use Score. We directly observed nurses to measure compliance with non-pharmacological measures to prevent ventilator-associated pneumonia. RESULTS: A total of 97 nurses were studied; 76 (79%) were observed. There were 327 observations (mean 4·30 observations per nurse). The questionnaire showed good baseline knowledge of preventive measures [mean score (92% ± 16%)]. Nurses complied with the preventive measures in 66% ± 15% of observations; compliance ranged from 11·9% for pre-aspiration hand washing to 99·7% for using sterile aspiration probes. Mean Nine Equivalents of Nursing Manpower Use Score for each nurse observed was 50 ± 13, without differences between centres (49 ± 14 versus 51 ± 11, p = 0·4). Overall compliance was lower in the light workload group (p = 0·02), but no significant differences in compliance between workload groups were found when each measure was analysed separately. Compliance was higher in nurses aged 31-40 years than in those aged >51 years, although workload was similar in both groups. CONCLUSIONS: Compliance with non-pharmacological measures to prevent ventilator-associated pneumonia varies widely; non-compliance is not because of increased workload. RELEVANCE TO CLINICAL PRACTICE: Most critical care nurses have good baseline knowledge of non-pharmacological measures to prevent ventilator-associated pneumonia. Failure to comply with these measures is probably more related with behavioural, structural and organizational aspects than with nursing workload. Interventions to improve compliance might be more effective if they focus on factors such as work climate and professionals' attitudes.

Outpatient multimodal intravenous analgesia in patients undergoing day-case surgery: description of a three year experience.

BACKGROUND: The use of elastomeric devices for ambulatory intravenous pain treatment in Major Ambulatory Surgery (MAS) has been described to improve postoperative pain management. The objective of the study was to describe the first 3 years experience of the use of elastomeric devices for ambulatory intravenous pain treatment in MAS implemented at our site since 2010. METHODS: Data were retrieved from the medical records for all patients who, between January 2010 and March 2014, underwent surgical procedures at the ambulatory surgical centre at our hospital and were prescribed a home-based continuous intravenous analgesia. RESULTS: Data were retrieved from the medical records of 1128 patients. The most frequent surgical interventions included orthopedic and proctology surgeries. 80 % of patients were discharged home without pain; during the first 48 h after discharge roughly 40 % of subjects were completely free of pain, 50 % reported mild pain (VAS 1 to 3) and 9 % reported higher pain scores (4 and above). Peripheral nerve block was associated to better pain control in the immediate postoperative period. Vomiting in the first 24 h was 4.6 % before introducing haloperidol into the drug schemes, and 2.6 % thereafter. Complications related with the intravenous route required treatment withdrawal in 1.1 % cases. Only 3.5 % of patients returned to the hospital in the first 72 h, mainly for non-pain related reasons. Overall, 99.5 % of patients were satisfied with the treatment received at home. CONCLUSION: Our initial experience suggest that outpatient multimodal intravenous analgesia in patients undergoing day-case surgery is a feasible alternative in our setting, that allows an effective management of postoperative pain with a small rate of adverse events and complications requiring readmission.

Mental Health Emergencies in Paediatric Services: Characteristics, Diagnostic Stability and Gender differences.

INTRODUCTION: Child and adolescent psychiatric emergencies have increased in recent years. The main objective of our study is to analyze sociodemographic and clinical characteristics of psychiatric emergencies under 18 years old that came to our hospital. Secondary objectives were to study diagnostic stability made in the emergency department and undertake a gender analysis. METHODS: Descriptive cross-sectional study of patients attending the pediatric emergency department who required consultation to psychiatry service during 2010 and 2011, comparing data with two previous cross-sectional cuts (2002-2003 and 2006-2007). Then we track the diagnoses assigned during a year. Statistical analysis was descriptive. We also include a gender analysis. RESULTS: We analyzed 328 episodes corresponding to 179 different patients (average age 14.48). We detected a progressive increase of prevalence of psychiatric emergencies from 2002 to 2011. Diagnostic distribution showed a significant association of Behavioral Disorders with males and an association of Self-injured Behaviors and Eating Disorders with females. The admission rate was 18.5%. One-year diagnostic outcomes showed differences comparing to emergency diagnosis. CONCLUSIONS: Increase and complexity of psychiatric consultations in Pediatric Emergency Department requires a greater coordination and training of these services to enhance patients care. Emergency visit could mean the entrance of complex and severe patients to a specialized care. Our results detect gender differences: more Behavioral Disorders, Psychosis and Substance Use Disorders in males and Self-Injury and Eating Behavior Disorders in females.

Relationship between volume and survival in closed intensive care units is weak and apparent only in mechanically ventilated patients.

BACKGROUND: Recent studies have found an association between increased volume and increased intensive care unit (ICU) survival; however, this association might not hold true in ICUs with permanent intensivist coverage. Our objective was to determine whether ICU volume correlates with survival in the Spanish healthcare system. METHODS: Post hoc analysis of a prospective study of all patients admitted to 29 ICUs during 3 months. At ICU discharge, the authors recorded demographic variables, severity score, and specific ICU treatments. Follow-up variables included ICU readmission and hospital mortality. Statistics include logistic multivariate analyses for hospital mortality according to quartiles of volume of patients. RESULTS: The authors studied 4,001 patients with a mean predicted risk of death of 23% (range at hospital level: 14-46%). Observed hospital mortality was 19% (range at hospital level: 11-35%), resulting in a standardized mortality ratio of 0.81 (range: 0.5-1.3). Among the 1,923 patients needing mechanical ventilation, the predicted risk of death was 32% (14-60%) and observed hospital mortality was 30% (12-61%), resulting in a standardized mortality ratio of 0.96 (0.5-1.7). The authors found no correlation between standardized mortality ratio and ICU volume in the entire population or in mechanically ventilated patients. Only mechanically ventilated patients in very low-volume ICUs had slightly worse outcome. CONCLUSION: In the currently studied healthcare system characterized by 24/7 intensivist coverage, the authors found wide variability in outcome among ICUs even after adjusting for severity of illness but no relationship between ICU volume and outcome. Only mechanically ventilated patients in very low-volume centers had slightly worse outcomes.

An Exploratory Analysis on the 2D:4D Digit Ratio and Its Relationship with Social Responsiveness in Adults with Prader-Willi Syndrome.

Prader-Willi syndrome (PWS) is a genetic disorder produced by a lack of expression of paternally derived genes in the 15q11-13 region. Research has generally focused on its genetic and behavioral expression, but only a few studies have examined epigenetic influences. Prenatal testosterone or the maternal testosterone-to-estradiol ratio (MaTtEr) has been suggested to play an important role in the development of the 'social brain' during pregnancy. Some studies propose the 2D:4D digit ratio of the hand as an indirect MaTtEr measure. The relationship between social performance and MaTtEr has been studied in other neurodevelopmental conditions such as Autism Spectrum Disorder (ASD), but to our best knowledge, it has never been studied in PWS. Therefore, our study aims to clarify the possible existence of a relationship between social performance-as measured using the Social Responsiveness Scale (SRS)-and MaTtEr levels using the 2D:4D ratio. We found that, as a group, PWS individuals have shorter index and ring fingers than the control group, but no significant difference in the 2D:4D ratios. The 2D:4D ratio showed a correlation only with Restricted Interests and Repetitive Behavior Subscale, where a positive correlation only for male individuals with PWS was found. Considering only PWS with previous GH treatment during childhood/adolescence (PWS-GH), index and ring fingers did not show differences in length with the control group, but the 2D:4D ratio was significantly higher in the right or dominant hand compared to controls.

Real-World Outcomes in Patients with Metastatic Colorectal Cancer in Spain: The RWD-ACROSS Study.

The retrospective, observational RWD-ACROSS study analyzed disease characteristics, systemic treatment, and survival in patients with metastatic colorectal cancer (mCRC) in Spain. In total, 2002 patients were enrolled (mean age 65.3 years; 62.7% male). Overall median overall survival (OS) was 26.72 months, and was longer in patients with left-sided tumors (28.85 vs. 21.04 months (right-sided tumors); p < 0.0001) and in patients receiving first-line anti-epidermal growth factor receptor (EGFR) treatment (31.21 vs. 26.75 (anti-vascular endothelial growth factor (VEGF) treatment) and 24.45 months (chemotherapy); p = 0.002). Overall median progression-free survival (PFS) was 10.72 months and was longer in patients with left-sided tumors (11.24 vs. 9.31 months (right-sided tumors); p < 0.0001), and in patients receiving either first-line anti-EGFR or anti-VEGF (12.13 and 12.00 vs. 8.98 months (chemotherapy); p < 0.001). PFS was longer with anti-VEGF treatment in patients with right-sided tumors and wild-type RAS (11.24 vs. 8.78 (anti-EGFR) and 7.83 months (chemotherapy); p = 0.025). Both anti-EGFR and anti-VEGF produced longer PFS in patients with left-sided tumors and wild-type RAS than chemotherapy alone (12.39 and 13.14 vs. 9.83 months; p = 0.011). In patients with left-sided tumors and mutant RAS, anti-VEGF produced a longer PFS than chemotherapy alone (12.36 vs. 9.34 months; p = 0.001). In Spain, wild-type RAS or left-sided mCRC tumors are predictive of longer survival times.

An adapted scale to evaluate insight in Prader-Willi Syndrome.

OBJECTIVE: To develop an insight scale for Prader-Willi Syndrome (PWS), a genetically determined neurodevelopmental disorder with different psychopathological and behavioural problems. METHODOLOGY: A sample of 36 PWS patients (58.3% women) attended at the Endocrinological Department of the Corporació Sanitària Parc Taulí (Sabadell, Barcelona) was evaluated. Insight was assessed by means of an adapted version of the Scale of Unawareness of Mental Disorder (SUMD), including three general insight dimensions: awareness of having a PWS, awareness of the effects of psychopharmacological medication and awareness of the social consequences, as well as three items that assess awareness of each particular symptom of the disease (obesity/overweight, excessive appetite and excessive food intake). RESULTS: The final Scale included six items and demonstrated an adequate internal consistency (Cronbach Alfa of 0.857 for Caregivers and 0.798 for Clinicians) but a high inter-rate variability. External validation using an Analytical-Visual Insight Scale was adequate. CONCLUSIONS: The Adapted version for Prader-Willi patients of the Scale of Unawareness of Mental Disorder (APW-SUD) showed adequate psychometric properties and it is an easy to administer means to assess insight in this population.

Social Responsiveness and Psychosocial Functioning in Adults with Prader-Willi Syndrome.

Although various studies have investigated symptoms of autism spectrum disorder (ASD) in Prader−Willi syndrome (PWS), little is known about the consequences of these symptoms, especially in psychosocial function. We aimed to explore ASD symptoms in adults with PWS with special attention to psychosocial functionality. This cross-sectional study included 26 adults (15 women) with PWS who attended a reference unit for rare diseases. Participants' primary caregivers completed the Social Responsiveness Scale (SRS), and clinicians assessed multidimensional functioning with the Personal and Social Performance Scale (PSP). Impaired social responsiveness was identified in 20 (76.9%) participants, and manifest to marked difficulties in social functioning were identified in 13 (50%). Participants with impaired social responsiveness (SRS ≥ 60) had significantly worse scores in functionality measured with the PSP (U = 12.5; p = 0.009) and with three of the four PSP main areas. Moreover, scores for the Social Cognition domain of the SRS correlated positively with the Socially useful activities (p < 0.05) and Personal and social relationships (p < 0.01) main areas of the PSP. These results suggest that difficulties in social skills should be assessed in all psychosocial evaluations of patients with PWS.

Prognostic value of lymphocyte-to-monocyte ratio previously determined to surgery in patients with non-metastatic renal cell carcinoma: A systematic review and a prisma-compliant meta-analysis.

BACKGROUND: The prognostic value of pretreatment lymphocyte to monocyte ratio in patients with renal cell carcinoma and, especially, in non-metastatic patients remains controversial. METHODS: We conducted a PRISMA-compliant meta-analysis to systematically assess the prognostic value of LMR in patients with non-metastatic RCC. Overall survival, cancer-specific survival, and disease-free survival were analyzed. Pooled hazard ratios and 95% confidence intervals were calculated. RESULTS: Seven studies comprising 4666 patients were included in the analysis. Unlike those observed in a previous meta-analysis, a lower lymphocyte to monocyte ratio was associated with poorer cancer-specific survival (fix-effect model, hazard ratio 3.04, 95% confidence intervals 2.05-4.51, P < .05). Heterogeneity Chi-squared value Q exp = 0. (P = .82) (I2 = 0%). However, the association between a low lymphocyte to monocyte ratio and overall survival or disease-free survival did not obtain significance. CONCLUSION: A lower lymphocyte to monocyte ratio implied poor cancer-specific survival in patients with non-metastatic renal cell carcinoma. Prospective studies are required to confirm our findings. REGISTRATION NUMBER: ClinicalTrials.gov (identifier: NCT04213664).

Multidimensional Evaluation of Awareness in Prader-Willi Syndrome.

There are no studies about insight or awareness of illness in patients with Prader-Willi Syndrome (PWS). The objective of this study was to explore the level of awareness of the disorder, of the need for medication, and of the social consequences of the disease, as well as of its main symptoms in PWS. We also aimed to explore relationships between awareness and sociodemographic and clinical characteristics, and to compare all data with a matched sample of patients with psychosis. Insight was assessed by an Adapted version of the Scale of Unawareness of Mental Disorder in a cross-sectional pilot study at a University Hospital. Thirty-six individuals with PWS (58.3% women) were included. Results showed that PWS patients had a good awareness of the illness and of the effects of medication, in contrast to a lack of awareness of illness' social consequences. Awareness of obesity/overweight was excellent, as was the awareness of excessive appetite. Awareness of excessive food intake was only mild. Insight correlated with age and functionality, but not with BMI. PWS patients showed a better insight into the illness but a similar awareness of the effects of the medication and of the social consequences of the disease as compared to schizophrenia-spectrum patients. This profile of insight may have relevant clinical implications.

Association of Calcitriol Supplementation with Reduced COVID-19 Mortality in Patients with Chronic Kidney Disease: A Population-Based Study.

Treatment with calcitriol, the hormonal form of vitamin D, has shown beneficial effects in experimental models of acute lung injury. In this study, we aimed to analyze the associations between calcitriol supplementation and the risk of SARS-CoV2 infection or COVID-19 mortality. Individuals ≥18 years old living in Catalonia and supplemented with calcitriol from April 2019 to February 2020 were compared with propensity score matched controls. Outcome variables were SARS-CoV2 infection, severe COVID-19 and COVID-19 mortality. Associations between calcitriol supplementation and outcome variables were analyzed using multivariable Cox proportional regression. A total of 8076 patients were identified as being on calcitriol treatment. Advanced chronic kidney disease and hypoparathyroidism were the most frequent reasons for calcitriol supplementation in our population. Calcitriol use was associated with reduced risk of SARS-CoV2 infection (HR 0.78 [CI 95% 0.64-0.94], p = 0.010), reduced risk of severe COVID-19 and reduced COVID-19 mortality (HR 0.57 (CI 95% 0.41-0.80), p = 0.001) in patients with advanced chronic kidney disease. In addition, an inverse association between mean daily calcitriol dose and COVID-19 severity or mortality was observed in treated patients, independently of renal function. Our findings point out that patients with advanced chronic kidney disease could benefit from calcitriol supplementation during the COVID-19 pandemic.

Religiosity and Psychotic Ideation in Stable Schizophrenia: A Role for Empathic Perspective-Taking.

The relationship between religiosity and different components of empathy was explored in schizophrenia patients. A total of 81 stable schizophrenia patients and 95 controls from the nearby community completed self-reported questionnaires assessing religiosity and empathy (through the Interpersonal Reactivity Index, IRI). Patients with schizophrenia showed higher religiousness than controls and they presented less perspective-taking and empathic concern but increased personal distress in IRI scores. Regression analyses unveiled an association between religiosity and perspective-taking in schizophrenics after adjusting for age, gender, and psychotic symptoms. In conclusion, religiosity in patients with schizophrenia may be linked to variations in perspective- taking as a component of empathy.

Nebulized Colistin And Continuous Cyclic Azithromycin In Severe COPD Patients With Chronic Bronchial Infection Due To Pseudomonas aeruginosa: A Retrospective Cohort Study.

Introduction: Long-term use of nebulized or oral antibiotics is common in the treatment of cystic fibrosis and non-cystic fibrosis bronchiectasis. To date, however, few studies have focused on the use of nebulized antibiotics in COPD patients. The aims of this study are: to establish whether a combination of nebulized colistin plus continuous cyclic azithromycin in severe COPD patients with chronic bronchial infection due to Pseudomonas aeruginosa reduces the frequency of exacerbations, and to assess the effect of this treatment on microbiological sputum isolates. Material and methods: A retrospective cohort was created for the analysis of patients with severe COPD and chronic bronchial infection due to P. aeruginosa treated with nebulized colistin at the Respiratory Day Care Unit between 2005 and 2015. The number and characteristics of COPD exacerbations (ECOPD) before and up to two years after the introduction of nebulized colistin treatment were recorded. Results: We analyzed 32 severe COPD patients who received nebulized colistin for at least three months (median 17 months [IQR 7-24]). All patients but one received combination therapy with continuous cyclic azithromycin (median 24 months [IQR 11-30]). A significant reduction in the number of ECOPD from baseline of 38.3% at two years of follow-up was observed, with a clear decrease in P. aeruginosa ECOPD (from 59.5% to 24.6%) and a P. aeruginosa eradication rate of 28% over the two-year follow-up. Conclusion: In patients with severe COPD and chronic bronchial infection due to P. aeruginosa, combination therapy with nebulized colistin and continuous cyclic azithromycin significantly reduced the number of ECOPD, with a marked decrease in P. aeruginosa sputum isolates.
