Ceftobiprole for Treatment of Complicated Bacteremia.

Background: Ceftobiprole is a cephalosporin that may be effective for treating complicated bacteremia, including methicillin-resistant .

Methods: In this phase 3, double-blind, double-dummy, noninferiority trial, adults with complicated bacteremia were randomly assigned in a 1:1 ratio to receive ceftobiprole at a dose of 500 mg intravenously every 6 hours for 8 days and every 8 hours thereafter, or daptomycin at a dose of 6 to 10 mg per kilogram of body weight intravenously every 24 hours plus optional aztreonam (at the discretion of the trial-site investigators). The primary outcome, overall treatment success 70 days after randomization (defined as survival, bacteremia clearance, symptom improvement, no new bacteremia-related complications, and no receipt of other potentially effective antibiotics), with a noninferiority margin of 15%, was adjudicated by a data review committee whose members were unaware of the trial-group assignments.

Assessment of Electromagnetic Field Exposure on European Roads: A Comprehensive In Situ Measurement Campaign.

The rapid evolution of wireless communication technologies (such as fifth-generation (5G) cellular networks) in the last years has allowed connecting different objects (from wearable electronics to vehicles) and people through communication networks, and at the same time, has led to widespread deployment of base stations. Along with this growth, questions about the potential adverse effects on human health due to electromagnetic fields (EMFs) from base station antennas have also been raised. In this paper, we focus on the assessment of EMFs in automobiles during short (between cities) and long (between countries) trips on several European roads.

Evolutionary trajectory of receptor binding specificity and promiscuity of the spike protein of SARS-CoV-2.

SARS-CoV-2 infects cells by attachment to its receptor-the angiotensin converting enzyme 2 (ACE2). Regardless of the wealth of structural data, little is known about the physicochemical mechanism of interactions of the viral spike (S) protein with ACE2 and how this mechanism has evolved during the pandemic. Here, we applied experimental and computational approaches to characterize the molecular interaction of S proteins from SARS-CoV-2 variants of concern (VOC).

Fully Textile Dual-Band Logo Antenna for IoT Wearable Devices.

In recent years, the interest in the Internet of Things (IoT) has been growing because this technology bridges the gap between the physical and virtual world, by connecting different objects and people through communication networks, in order to improve the quality of life. New IoT wearable devices require new types of antennas with unique shapes, made on unconventional substrates, which can be unobtrusively integrated into clothes and accessories. In this paper, we propose a fully textile dual-band logo antenna integrated with a reflector for application in IoT wearable devices.

It is time to define an organizational model for the prevention and management of infections along the surgical pathway: a worldwide cross-sectional survey.

Background: The objectives of the study were to investigate the organizational characteristics of acute care facilities worldwide in preventing and managing infections in surgery; assess participants' perception regarding infection prevention and control (IPC) measures, antibiotic prescribing practices, and source control; describe awareness about the global burden of antimicrobial resistance (AMR) and IPC measures; and determine the role of the Coronavirus Disease 2019 pandemic on said awareness.

Methods: A cross-sectional web-based survey was conducted contacting 1432 health care workers (HCWs) belonging to a mailing list provided by the Global Alliance for Infections in Surgery. The self-administered questionnaire was developed by a multidisciplinary team.

A Colorectal Cancer 3D Bioprinting Workflow as a Platform for Disease Modeling and Chemotherapeutic Screening.

Colorectal cancer (CRC) is the third most common malignancy and has recently moved up to the second leading cause of death among carcinomas. Prognosis, especially for advanced diseases or certain molecular subtypes of CRC, remains poor, which highlights the urgent need for better therapeutic strategies. However, currently, as little as 0.

WSES/GAIS/SIS-E/WSIS/AAST global clinical pathways for patients with intra-abdominal infections.

Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in hospitals worldwide. The cornerstones of effective treatment of IAIs include early recognition, adequate source control, appropriate antimicrobial therapy, and prompt physiologic stabilization using a critical care environment, combined with an optimal surgical approach. Together, the World Society of Emergency Surgery (WSES), the Global Alliance for Infections in Surgery (GAIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), and the American Association for the Surgery of Trauma (AAST) have jointly completed an international multi-society document in order to facilitate clinical management of patients with IAIs worldwide building evidence-based clinical pathways for the most common IAIs.

Luteolysis, progesterone, and pregnancy per insemination after modifying the standard 7-day Ovsynch program in Holstein-Friesian and Holstein cows.

Two experiments were conducted with Holstein-Friesian cows in the Republic of North Macedonia and with Holstein cows in Kansas. We hypothesized that 1 dose of PGF administered on d 8 (Ov-8×1) instead of d 7 (Ov-7×1) in an Ovsynch program [GnRH-1 (d 0)-7 d-PGF-56 h-GnRH-2-16 h-timed artificial insemination (AI)] would increase the proportion of cows with complete luteolysis compared with controls receiving a single dose on d 7. Cows were treated with Ov-7×1 or with Ov-8×1 in experiment 1 (n = 347), using only a single dose of PGF.

A rare case of double J stent migration in the kidney.

Double-J stents are among the basic and commonly used tools in urology. There are a lot of complications that can occur during DJ placement. We are presenting 62 years old woman, who was admitted in Urology Department with symptoms of left lumbar pain, irradiating towards inguinal area and hematuria.

Physiologic responses to feeding rumen-protected glucose to lactating dairy cows.

It was hypothesized that rumen-protected glucose (RPG) in diets of dairy cows increases concentrations of insulin resulting in greater blood progesterone concentrations because elevated insulin decreases activity of liver enzymes inactivating steroid hormones. Timing of ovulation was synchronized among 64 postpartum Holstein cows using GnRH and PGF (Day 0 = ovulation). Cows were milked thrice daily and assigned randomly a basal diet supplemented with 0, 1, 2, or 4 kg of an RPG product in place of corn grain, top-dressed in the diet beginning on Day -3.

Physiological parameters for Prognosis in Abdominal Sepsis (PIPAS) Study: a WSES observational study.

Background: Timing and adequacy of peritoneal source control are the most important pillars in the management of patients with acute peritonitis. Therefore, early prognostic evaluation of acute peritonitis is paramount to assess the severity and establish a prompt and appropriate treatment. The objectives of this study were to identify clinical and laboratory predictors for in-hospital mortality in patients with acute peritonitis and to develop a warning score system, based on easily recognizable and assessable variables, globally accepted.

Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA).

Introduction: No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question.

Material And Methods: A prospective analysis of adult patients enrolled in the IROA.

Knowledge, awareness, and attitude towards infection prevention and management among surgeons: identifying the surgeon champion.

Despite evidence supporting the effectiveness of best practices of infection prevention and management, many surgeons worldwide fail to implement them. Evidence-based practices tend to be underused in routine practice. Surgeons with knowledge in surgical infections should provide feedback to prescribers and integrate best practices among surgeons and implement changes within their team.

Prospective Observational Study on acute Appendicitis Worldwide (POSAW).

Background: Acute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis.

Laparoscopic combined colorectal and liver resections for primary colorectal cancer with synchronous liver metastases.

Backgrounds/aims: Synchronous liver metastases (SLMs) are found in 15-25% of patients at the time of diagnosis with colorectal cancer, which is limited to the liver in 30% of patients. Surgical resection is the most effective and potentially curative therapy for metastatic colorectal carcinoma (CRC) of the liver. The comparison of simultaneous resection of primary CRC and synchronous liver metastases with staged resections is the subject of debate with respect to morbidity.

Pathways of the dominant follicle after exposure to sub-luteal circulating progesterone concentrations are different in lactating dairy cows versus non-lactating heifers.

With the increased use of different synchronization programs in cattle, attention is given to the progesterone concentration during development of the ovulatory follicle. It has been shown that low peripheral progesterone concentrations during follicular development may lead to decreased fertility. To investigate the effect of low progesterone concentrations on the fate of the dominant follicle, a study was conducted where cycles of dairy cows and heifers were manipulated to induce the development of the first dominant follicle without progesterone (PLACEBO) or under sub-luteal progesterone concentrations from a progesterone releasing intravaginal device (PRID Delta(®)).

[Indirect standard cardiotocography plus fetal blood sampling versus indirect quantitative cardiotocography--a randomized comparative study in intrapartum monitoring].

Introduction: In previous papers we proposed ways to improve the diagnostic potential of the "quantitative cardiotocography" computer method, which allowed us to introduce clinical practice guidelines. Using these guidelines we aim to evaluate the effectiveness of quantitative cardiotocography (qCTG) as compared to standard cardiotocography (CTG) and, if necessary fetal blood sampling (FBS).

Material And Methods: The prospective study involves 220 pregnant women divided randomly into two groups.

Disoxaril mutants of Coxsackievirus B1: phenotypic characteristics and analysis of the target VP1 gene.

Disoxaril inhibits enterovirus replication by binding to the hydrophobic pocket within the VP1 coat protein, thus stabilizing the virion and blocking its uncoating. Disoxaril-resistant (RES) mutants of the Coxsackievirus B1 (CVB1/RES) were derived from the wild disoxaril-sensitive (SOF) strain (CVB1/SOF) using a selection approach. A disoxaril-dependent (DEP) mutant (CVB1/DEP) was obtained following nine consecutive passages of the disoxaril-resistant mutant in the presence of disoxaril.

[Structure and function of the cardiotocographic score (CTG-score) calculated by the "quantitative cardiotocography" computer method. Determining the significance of its components for the accuracy of the estimates for the ph of the fetus].

Introduction: In the last three years "quantitative cardiotocography" has become the main method for fetal monitoring during late pregnancy and birth in Sheynovo hospital - Sofia, Bulgaria. Our previous studies presented opportunities for increasing the diagnostic potential of the methodology. In this paper we offer a new approach to further improve the accuracy of prognostic values for fetal pH during labor.

Structural analysis and molecular modelling of the Cu/Zn-SOD from fungal strain Humicola lutea 103.

The native form of Cu/Zn-superoxide dismutase, isolated from fungal strain Humicola lutea 103 is a homodimer that coordinates one Cu(2+) and one Zn(2+) per monomer. Cu(2+) and Zn(2+) ions play crucial roles in enzyme activity and structural stability, respectively. It was established that HLSOD shows high pH and temperature stability.

Heme interacts with c1q and inhibits the classical complement pathway.

C1q is the recognition subunit of the first component of the classical complement pathway. It participates in clearance of immune complexes and apoptotic cells as well as in defense against pathogens. Inappropriate activation of the complement contributes to cellular and tissue damage in different pathologies, urging the need for the development of therapeutic agents that are able to inhibit the complement system.
