RESUMO
This study aimed to analyze temporal trends by gender and age in Clostridium difficile infection (CDI)-related hospitalization rates in the Autonomous Community of Madrid (Spain) over a 12-year period. A population-based cross-sectional study of all hospital admissions with a CDI diagnosis from 2003 to 2014 was carried out. Annual age-specific hospitalization rates were calculated by gender. All the analyses were performed separately for total hospitalizations and hospitalizations with CDI as the primary diagnosis. Joinpoint regression models were used to analyze time trends. A total of 13,526 hospital discharges were identified (26.8 % with CDI as the primary diagnosis). In both sexes, a gradient in age-specific rates was observed, ranging in 2014 from 5.92 hospitalizations per 100,000 person-years in patients <15 years of age to 378.96 in patients ≥85 years of age. Since 2009, in the age group of 15-44 years, both men and women presented an increasing trend of around 18 %. A significantly increasing trend was detected in women of age 45-84 years, with an estimated annual percentage of change of 7.6 % in the age group of 45-64 years, and rounding with 4.5 % in the age group of 65-84 years. In men of age 45-64 years, the average annual percentage of increase was 4.7 %, and it was 21.1 % between 2010 and 2014 in the age group of 65-74 years. No trends were identified in the 85 years and over age group. Surveillance methods to assess trends by age group should be implemented. Preventive and therapeutic initiatives should remain a priority.

We propose a network-driven transfer mode for cloud operations in a step towards a carrier SDN. Inter-datacenter connectivity is requested in terms of volume of data and completion time. The SDN controller translates and forwards requests to an ABNO controller in charge of a flexgrid network.
RESUMO
BACKGROUND: Key and core components of effective infection prevention and control programmes (IPCPs) issued by the European Centre for Disease Prevention and Control (ECDC) and the World Health Organization (WHO) have been described. WHO core component 1 relates to the structure, organization and management of IPCPs. AIM: The objective of this study was to assess the status and the time trends of some indicators of core component 1 of IPCPs in acute hospitals in Spain throughout the period 2012-2022. METHODS: Hospital-level data from the Spanish point prevalence survey for years 2012-2022 were analysed. Core component 1 indicators were calculated and tested for association to healthcare-associated infections (HAIs). In addition, trends were also examined. RESULTS: Overall, 67.0% and 57.2% of Spanish hospitals reported having an annual infection prevention and control (IPC) plan and an annual IPC report that was approved by the hospital managing director, respectively. The global median number of full-time equivalent (FTE) IPC nurses per 250 beds for the period was 0.87 and the global median number of FTE IPC doctors was 0.70. The rates of blood cultures and stool tests for Clostridioides difficile were 39.9 and 6.1 per 1000 patient-days, respectively. No significant correlation was found between core component 1 indicators and HAI prevalence. CONCLUSION: Spain is currently at a basic level on the structure, organization and management of IPCPs. Profound differences were found between hospitals depending on size and type.

BACKGROUND AND OBJECTIVE: In orthopedic surgery, it is clear that an optimal standardized closure technique has not yet been developed. Locally, there are no objective data describing the standard surgical practice in wound closure. The aim of this study is to analyze the clinical practice of surgical wound closure in orthopedic surgery by means of a survey of a representative local sample and thus obtain information on the context of closure in Spain. METHOD: an ad hoc group of specialists in orthopedic surgery and traumatology was formed. The group of experts, after analyzing the literature, developed a questionnaire of 32 closed multiple-choice questions divided into the following blocks: hemostasis, surgical wound closure (deep, superficial, and cutaneous), and dressings. RESULTS: A total of 471 surgeons responded to the survey completely and with sufficient information to perform the descriptive analysis. 79% believe that ATX can influence the decrease in surgical site infection rate. 96% believe that the type of deep closure at the level of the arthrotomy could influence outcomes and complications after hip and/or knee replacements. 85% believe that the type of shallow closure at the subcutaneous level may influence outcomes and complications after hip and/or knee replacement. 64% of surgeons use single-use incisional negative pressure therapy for the treatment of surgical wound complications (seroma, prolonged drainage, dehiscence). CONCLUSIONS: There is a high level of variability in wound closure in our setting and a low level of training on the subject. The authors recommend that the different scientific societies invest resources to improve training in this field and reduce the percentage of surgeons who are considered inadequately trained, as well as adapting closure techniques to those considered gold standard according to the evidence.

RESUMO
Nursing homes (NH) although conceptually they should look as much like a home as possible, NH have unquestionable similarities with a nosocomium as they are places where many patients with underlying diseases and comorbidities accumulate and where the transmission of microorganisms between residents and between residents and caregivers is frequent.We have not found any recommendations specifically aimed at the prevention of nosocomial infections in MRI by the major Public Health Agencies and, therefore, the Health Sciences Foundation (Fundación de Ciencias de la Salud) has convened a series of experts and 14 Spanish scientific societies to discuss recommendations that could guide NH personnel in establishing written programs for the control and reduction of these infections. The present document is the result of these deliberations and contains suggestions for establishing such control programs on a voluntary and flexible basis in NH. We also hope that the document can help the health authorities to encourage this control activity in the different territorial areas of Spain. In our opinion, it is necessary to draw up a written plan and establish the figure of a coordinator or person responsible for implementing these projects. The document includes measures to be implemented and ways of quantifying the reality of different problems and of monitoring the impact of the measures established.
RESUMO
We studied the spatiotemporal variation of the photochemical reflectance index (PRI) and the chlorophyll content index (CHL index) in a terrestrial moss, using self-watering transplants distributed in 8 sampling sites that were sampled periodically during up to 4 years. We did not detect any seasonal patterns or difference between the studied sites, and therefore the variation across the sites reflected the influence of environmental variables in the area. We established the reference thresholds associated with physiological stress as -0.212 for PRI and 1.195 for CHL index. Our findings could be applied for biomonitoring atmospheric contamination on the basis of the physiological stress shown by the moss used.

BACKGROUND: Surveillance of antimicrobial consumption is an important component of control strategies to tackle antimicrobial resistance. AIM: To evaluate the consumption of antimicrobials using six indicators proposed by the European Center for Disease Prevention and Control. METHODS: Point prevalence survey data on antimicrobial use in Spanish hospitals throughout the period 2012-2021 were analysed. A descriptive analysis of each indicator by year was performed globally and by hospital size. A logistic regression model was used to identify significant time trends. FINDINGS: In all, 515,414 patients and 318,125 antimicrobials were included. The prevalence of antimicrobial use remained stable throughout the study period (45.7%; 95% confidence interval (CI): 45.6-45.8). Percentages of antimicrobials for systemic use and those administered parenterally showed a small and significant increasing trend (odds ratio (OR): 1.02; 95% CI: 1.01-1.02; and OR: 1.03; 95% CI: 1.02-1.03, respectively). Small improvements were found in the percentages of antimicrobials prescribed for medical prophylaxis and with the reason for use documented in patients' medical records (-0.6% and 4.2%, respectively). The percentage of surgical prophylaxis prescribed for more than 24 h shows a significant improvement, decreasing from 49.9% (95% CI: 48.6-51.3) in 2012 to 37.1% (95% CI: 35.7-38.5) in 2021. CONCLUSION: During the last decade, Spanish hospitals have had a stable but high prevalence of antimicrobial use. Little to no improvement has been made in most of the indicators analysed, except for a reduction in the prescription of surgical prophylaxis for more than 24 h.

OBJECTIVE: To provide latest findings of Urologic Oncology on prostate, kidney, and bladder cancer, and analyze its impact on clinical practice as well as future schemes in the medium- and long-term. METHODS: This document reviews the abstracts on Uro-Oncology presented at the 2020 Congresses (EUA, AUA, ASCO, ESMO and ASTRO), the publications with the highest impact and especially the new lines of development and progress in Uro-Oncology evaluated by the OncoForum committee. RESULTS: The use of prostate-specific membrane antigen (PSMA) radioligands in the diagnosis of prostate cancer may have great potential and utility in the coming years due to their improved sensitivity and specificity. The genetic characterization of the tumor is important at both, germline and somatic levels, due to the significant role of BRCA2 mutations regarding risk. The cohort multiple randomised controlled trial is the most suitable study design at the genitourinary cancer level. The application of big data will lead to process improvements, savings in healthcare costs, and an empowerment of real-life studies through ease of data comparison, management, and storage. CONCLUSIONS: The use of new diagnostic techniques with PSMA ligands will provide a more comprehensive diagnostic modality, increase the number of studies about tumor genetic profiling, and enhance their quality. The practical application of artificial intelligence will improve the treatment genitourinary cancer.

INTRODUCTION: Penile fracture (PF) is a urological emergency with low incidence, and evidence of its long-term outcomes is scarce. This study focuses on postoperative complications and long-term functional outcomes in patients with PF and surgical repair at our center. MATERIALS AND METHOD: Clinical records of patients undergoing urgent surgery for PF at a third level hospital between 2006 and 2020 were retrospectively reviewed. Functional outcomes were assessed with voluntary telephone interviews from June 2020 to February 2021. Lower urinary tract symptoms were screened by IPSS questionnaire, sexual function by EHS and IIEF-5 and morphological alterations by direct questions to patients. RESULTS: A total of 41 patients underwent surgery for PF. Eleven of them also had urethral injury (higher incidence if there was bilateral corpora cavernosa injury, 19.4% vs. 80%, pâ¯<â¯0.05). Only 1 patient presented a Clavien-Dindo type 3a complication due to wound dehiscence, 4 (13%) type 2 and 9 (29%) type 1. Twenty-four patients underwent long-term follow-up, of whom 20 (83.3%) presented normal sexual function. Twelve patients (50%) had a palpable nodule at the fracture site, 8 (33.3%) had new onset penile curvature and 1 patient with previous urethral injury presented urethral stricture. CONCLUSION: In cases of penile fracture, there is a higher incidence of urethral injury if both corpora cavernosa are affected. Long-term functional sequelae after surgical repair of a PF are rare.

INTRODUCTION AND OBJECTIVE: Survival and quality of life (QoL) of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) deteriorate significantly when they develop metastases. New generation antiandrogens (apalutamide, enzalutamide and darolutamide) can prolong metastasis-free survival (MFS) and overall survival (OS) in these patients, maintaining their QoL. MATERIAL AND METHODS: After the performance of a systematic review of the literature, a scientific committee reached a consensus on simple and practical recommendations to consolidate and improve the management of patients with nmCRPC in urology consultations. RESULTS: Recommendations are made on the frequency of PSA determination and imaging tests in patients with nmCRPC. The importance of co-morbidities in patients with nmCRPC is also highlighted, and recommendations are also made on functional and QoL assessment that can be carried out during urology consultations. The efficacy, safety, and effects on QoL of new generation antiandrogens are reviewed. CONCLUSIONS: To evaluate treatment of patients with nmCRPC, it is necessary to consider co-morbidities and QoL, in addition to age. New generation antiandrogens are a safe and effective treatment option for patients with nmCRPC. The recommendations of this review can be helpful in optimizing the management of nmCRPC patients in urology consultations.

Ambient air quality, pollution and its implication on health is a topic of enormous importance that is normally dealt with by major specialists in their particular areas of interest. In general, it is not discussed from multidisciplinary approaches or with a language that can reach everyone. For this reason, the Health Sciences Foundation, from its prevention area, has formulated a series of questions to people with very varied competences in the area of ambient air quality in order to obtain a global panorama of the problem and its elements of measurement and control. The answers have been produced by specialists in each subject and have been subjected to a general discussion that has allowed conclusions to be reached on each point. The subject was divided into three main blocks: external ambient air, internal ambient air, mainly in the workplace, and hospital ambient air and the consequences of its poor control. Along with the definitions of each area and the indicators of good and bad quality, some necessary solutions have been pointed out. We have tried to know the current legislation on this problem and the competences of the different administrations on it. Despite its enormous importance, ambient air quality and health is not usually a topic of frequent presence in the general media and we have asked about the causes of this. Finally, the paper addresses a series of reflections from the perspective of ethics and very particularly in the light of the events that the present pandemic raises. This work aims to provide objective data and opinions that will enable non-specialists in the field to gain a better understanding of this worrying reality.

We present a case of endocarditis caused by Aspergillus in a lung transplant (LT) patient and review 6 previously reported cases. All cases were caused by Aspergillus fumigatus. Five patients (71%) were transplanted due to cystic fibrosis. None of the patients had any previously known valvular heart disease. The time that elapsed between LT surgery and the diagnosis of Aspergillus endocarditis was 8±6 months. Large peripheral emboli were observed in 6 patients (85%); blood cultures were negative in all. Transthoracic echocardiography did not detect the presence of vegetations in 3 patients (43%); the vegetations measured >1.5 cm in all cases. Five patients (71%) died from disseminated disease. Both survivors underwent combined therapy with antifungal drugs and surgical treatment.

Healthcare-associated infections (HAIs) are the most common adverse outcomes due to delivery of medical care. HAIs increase morbidity and mortality, prolong hospital stay, and are associated with additional healthcare costs. Contaminated surfaces, particularly those that are touched frequently, act as reservoirs for pathogens and contribute towards pathogen transmission. Therefore, healthcare hygiene requires a comprehensive approach whereby different strategies may be implemented together, next to targeted, risk-based approaches, in order to reduce the risk of HAIs for patients. This approach includes hand hygiene in conjunction with environmental cleaning and disinfection of surfaces and clinical equipment. This review focuses on routine environmental cleaning and disinfection including areas with a moderate risk of contamination, such as general wards. As scientific evidence has not yet resulted in universally accepted guidelines nor led to universally accepted practical recommendations pertaining to surface cleaning and disinfection, this review provides expert guidance for healthcare workers in their daily practice. It also covers outbreak situations and suggests practical guidance for clinically relevant pathogens. Key elements of environmental cleaning and disinfection, including a fundamental clinical risk assessment, choice of appropriate disinfectants and cleaning equipment, definitions for standardized cleaning processes and the relevance of structured training, are reviewed in detail with a focus on practical topics and implementation.

It is now well-established that dysregulation of the tricarboxylic acid (TCA) cycle enzymes succinate dehydrogenase, fumarate hydratase, and isocitrate dehydrogenase leads to the abnormal cellular accumulation of succinate, fumarate, and 2-hydroxyglutarate, respectively, which contribute to the formation and malignant progression of numerous types of cancers. Thus, these metabolites, called oncometabolites, could potentially be useful as tumour-specific biomarkers and as therapeutic targets. For this reason, the development of analytical methodologies for the accurate identification and determination of their levels in biological matrices is an important task in the field of cancer research. Currently, hyphenated gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) techniques are the most powerful analytical tools in what concerns high sensitivity and selectivity to achieve such difficult task. In this review, we first provide a brief description of the biological formation of oncometabolites and their oncogenic properties, and then we present an overview and critical assessment of the GC-MS and LC-MS based analytical approaches that are reported in the literature for the determination of oncometabolites in biological samples, such as biofluids, cells, and tissues. Advantages and drawbacks of these approaches will be comparatively discussed. We believe that the present review represents the first attempt to summarize the applications of these hyphenated techniques in the context of oncometabolite analysis, which may be useful to new and existing researchers in this field.

INTRODUCTION: Collagenase Clostridium histolyticum (CCH) is the only approved treatment for conservative management of Peyronie's disease (PD) that has demonstrated efficacy and safety in clinical trials. However, as the standard treatment protocol is time and resource consuming, we are introducing a new CCH treatment protocol with a more cost-effective profile. Our goal is to evaluate its efficacy and safety. MATERIALS AND METHODS: We included patients with PD in stable phase, with curvatures of 30-90degrees. Ventral curvatures and complex deformities were excluded. The treatment protocol consists of a full dose of CCH injected along the PD plaque, forming two lines of four injections. Patients were educated in daily penile modeling activities. The need for a new treatment cycle, up to a maximum of 8 cycles or until the 30-degree curve was decreased, was reevaluated every 4weeks. Changes in curvature and number of cycles were recorded to evaluate the efficacy. Regarding safety evaluation, treatment-related adverse events (TRAEs) were recorded, including rupture of the corpora cavernosa, penile hematoma, hematuria, and local infection. RESULTS: Thirty-one patients were treated under the modified protocol. The mean initial curvature was of 49.84 (±15.83) degrees. Curvature improvement was recorded in 25 patients (80.6%), with a mean absolute reduction of 20.65 (±15.42) degrees and relative reduction of 44%. The mean curvature after treatment was 30.67 (±17.25) degrees. Most patients required one (19.4%) or two (54.8%) injections. No patient presented TRAEs. CONCLUSIONS: The results suggest that the modified CCH treatment protocol is effective and safe, but more studies should be carried out to optimize the current standard protocol.

The human epidermal growth factor receptor 2 (HER2) is a transmembrane protein that has become one of the most specific prognostic and predictive biomarker of breast cancer. Its early detection is key for optimizing the patient clinical outcome. This work is focused on the detection of HER2 in individual cells using an antibody containing lutetium (Lu) as reporter group that is monitored by introducing the individual cells into the inductively coupled plasma mass spectrometer (ICP-MS). This Lu-containing antibody probe is used to label different breast cancer cell lines considered HER2 negative (MDA-MB-231) and positive (SKBR-3 and BT-474). Optimizations regarding the amount of the probe necessary to ensure complete labelling reactions are conducted in the different cell models. Concentrations in the range of 0.006 fg Lu/cell and 0.030 fg Lu/cell could be found in the HER2 negative and HER2 positive cells, respectively. In addition, the selectivity of the labelling reaction is tested by using two different metal-containing antibody probes for HER2 (containing Lu) and for transferrin receptor 1 (containing Nd), respectively, within the same cell population. Finally, the methodology is applied to the targeting of HER2 positive cells in complex cell mixtures containing variable amounts of BT-474 and MDA-MB-231 cells. The obtained results showed the excellent capabilities of the proposed strategy to discriminate among cell populations. This finding could help for scoring HER2 positive tumors improving existing technologies.

Allelic polymorphisms dramatically influence the phenotype of human killer immunoglobulin-like receptors (KIR) by modifying their expression in cell surfaces. It is unclear though to what extent this involves transcriptional or post-transcriptional mechanisms, as quantitative RNA expression of KIR alleles has not been systematically compared. We measured RNA transcript abundance of common KIR alleles by real-time quantitative reverse transcriptase PCR (RT-PCR) in 85 PBL samples that were allele-typed in parallel. Allele type showed little influence on transcript abundance for a given KIR gene, except for: (1) KIR2DL5B*002, which consistently showed undetectable transcripts levels; (2) truncated KIR2DS4 alleles, associated with lowered expression levels; and (3) alleles of KIR2DL4 with a single-base deletion, associated with higher expression than average. Lowered levels of truncated KIR2DS4 transcripts were confirmed by dot blot of RT-PCR products, indicating imbalanced allelic RNA expression in heterozygote genotypes containing these alleles. Imbalanced expression of truncated KIR2DS4 alleles was corroborated in family samples. Gene copy number of KIR2DL1, KIR2DL3 and KIR3DL1 influenced RNA expression, genotypes with a single copy expressing on average lower transcript amounts than those with two copies. The data show that for a given KIR gene, the common allele types found in our population express comparable RNA levels, except truncated or null alleles. Thus, variation of KIR expression on cell surfaces more likely involves post-transcriptional mechanisms.

BACKGROUND: The prevalence of hospital-acquired Methicillin-resistant Staphylococcus aureus (MRSA) infections shows a huge variety across Europe. Some countries reported a reduction in MRSA frequency, while in others countries increasing MRSA rates have been observed. To reduce the spread of MRSA in the healthcare setting, a sufficient MRSA management is essential. In order to reflect the MRSA management across Europe, MRSA prevention policies were surveyed in ten countries. MATERIALS AND METHODS: The survey was performed by questionnaires in European intensive care units (ICUs) and surgical departments (SDs) in 2004. Questionnaires asked for availability of bedside alcohol hand-disinfection, isolation precautions, decolonization and screening methods. The study was embedded in the Hospital in Europe Link for Infection Control through Surveillance (HELICS) Project, a European collaboration of national surveillance networks. HELICS was initiated in order to harmonize the national surveillance activities in the individual countries. Therefore, HELICS participants developed surveillance modules for nosocomial infections in ICUs and for surgical site infections (SSI). The coordination of this surveillance has now been transferred to the European Centre for Disease Prevention and Control (ECDC). RESULTS: A total of 526 ICUs and 223 SDs from ten countries sent data on organisational characteristics and policies, demonstrating wide variations in care. Substantial variation existed in availability of bedside alcohol hand-disinfection, which was much higher in participating ICUs rather than in SDs (86 vs. 59%). Surveillance cultures of contact patients were obtained in approximately three-fourths of all SDs (72%) and ICUs (75%). Countries with decreasing MRSA proportions showed especially strict implementation of various prevention measures. CONCLUSION: The data obtained regarding MRSA prevention measures should stimulate infection control professionals to pursue further initiatives. Particularly, the vigorous MRSA management in countries with decreasing MRSA proportions should encourage hospitals to implement preventive measures in order to reduce the spread of MRSA.
