Conceptual design and environmental evaluation of the Biorefinery approach for R-phycoerythrin extraction and purification.

Marine algae are considered promising resources both at present and in the near future. Their availability, together with their molecular structure and properties, increases their applicability in various sectors: food and feed, cosmetics, pharmaceuticals and bioenergy. However, the "bio" qualification does not always imply a lower impact compared to fossil-based process schemes.

Unveiling underlying factors for optimizing light spectrum to enhance microalgae growth.

Emerging research highlights the potential of specific light spectral regions to significantly enhance microalgae biomass production compared to conventional white light illumination. However, conflicting results of existing studies on the most optimal wavelengths reveal a knowledge gap regarding the underlying factors for optimal spectrum. The present paper aims to address this gap by critically analyzing existing studies on light spectral quality and its impact on microalgae growth.

Environmental impact scenarios of organic fraction municipal solid waste treatment with Black Soldier Fly larvae based on a life cycle assessment.

Biowaste treatment with Black Soldier Fly (BSF) larvae is an alternative option for organic waste valorization. Its environmental impacts should be assessed and compared with conventional treatment options. The research aims to evaluate the treatment of organic fraction of municipal solid waste (OFMSW) with BSF larvae through a life cycle assessment (LCA).

Feasibility and efficacy of routinary PECs 1 block on perioperative and postoperative pain control in breast surgery: a prospective non-controlled trial in a medium-volume breast unit.

Strategies to reduce the postoperative pain in patients undergoing breast cancer surgery include the use of Interpectoral (PECs) block, first described by Blanco in 2011, but its feasibility and efficacy in everyday clinical practice has been debated. The aim of the study was to evaluate the routine feasibility and effectiveness of PECs block added to general anesthesia to reduce postoperative pain and opioids consumption in the Breast Unit's patients. From June to December 2021 all patients undergoing surgery were included to receive PECs1 block before general anesthesia; clinical and outcome data were prospectively collected.

Pinch Grip per SE Is Not an Occupational Risk Factor for the Musculoskeletal System: An Experimental Study on Field.

Introduction: Some ergonomic evaluation methods define pinch grip as a risk factor independent of the exerted force. The present experimental study was performed with the main aim of objectively measuring the muscle engagement during the execution of pinch grip.

Methods: the participants of the study were healthy workers occupationally involved in a high-intensity repetitive job related to the sorting of letters and small packages.

Importance of Work-Related Psychosocial Factors in Exertion Perception Using the Borg Scale Among Workers Subjected to Heavy Physical Work.

This study aimed to analyse the role of several environmental and time variables, as well as individual and psychosocial factors, on the perception of exertion, expressed by using the Borg scale, on logistics workers performing heavy manual tasks. We enrolled 56 subjects working in logistics sector that were interviewed on the perceived exertion required to execute a task of manual lifting of heavy loads, by using the Borg scale. The interviews were carried out during different shifts, at different times during the shifts and during several different months of the year.

Complex lesion of the third metacarpophalangeal joint: complete tear of the radial collateral and deep transverse metacarpal ligament.

Injuries of collateral ligaments of MCPs joints are often underdiagnosed but have to be considered serious traumas of the hand. In many cases they concern thumb and rarely long fingers. Closed rupture of the deep transverse metacarpal ligament (DTML) is an unusual parallel injury.

The alterations of the sigmoid-rectal junction in diverticular disease of the colon revealed by MR-defecography.

Purpose: The sigmoidorectal junction (SRJ) has been defined as an anatomical sphincter with particular physiological behavior that regulates sigmoid and rectum evacuation. Its function in clinical conditions, such as diverticular disease has been advocated. The aim of our study is to identify the SRJ and to compare the morphometric and dynamic features of the SRJ between patients with diverticular disease and healthy subjects using MR-defecography.

Laparoscopic colorectal surgery in urgent and emergent settings.

Laparoscopic colectomy (LC) is slowly becoming the standard of care for elective resections. The use of LC in the emergency setting is relatively unstudied. Authors describe their experience with a series of 34 emergent and urgent LC cases for a variety of benign and neoplastic colorectal diseases, admitted from 2007 to 2009 at Emergency Department of a tertiary level hospital, comparing laparoscopic group with matched control open group.

Gerota's fascia flap: a technique for autogenous packing in major liver injuries.

Hepatic trauma occurs in ∼ 5% of patients admitted to emergency rooms and nonoperative management has become the standard of care in hemodynamically stable patients with blunt trauma, for most of the injured solid organs. However, the staged surgery represents the first line of treatment in hemodynamically instable patients. The abdominal packing is considered the first step of this surgical policy.

[Emergency laparoscopic cholecystectomy in the treatment of acute cholecystitis: when and how?].

Optimal surgical timing and operative technique in the treatment of acute cholecystitis are of major importance and are still debatable issues. We report the results of our study on the timing of surgery in a consecutive series of 163 patients treated in the emergency setting for acute cholecystitis over the period from 1998 to 2008. Early surgery and the partially downwards laparoscopic cholecystectomy technique provide a safe and effective way of treating these patients and preventing major complications.

The best timing of surgery in laparoscopic cholecystectomy for acute cholecystitis: when and how is to be performed.

Background/aims: In the treatment of acute cholecystitis the optimal timing of operation, regardless of whether performed laparoscopically or conventionally, is of major importance and not yet well defined feature among the different authors. We report our study on the timing of surgery in a consecutive series of 133 patients.

Methodology: The surgical technique consists in a partially downwards cholecystectomy from the infundibulum to the cystic duct.

[Therapeutic and diagnostic protocol for mild acute biliary pancreatitis: our experience and review of the literature].

Through a critical review of the literature, the authors analyze and re-assess the current diagnostic and therapeutic algorithms used in the treatment of mild acute biliary pancreatitis, reporting their experience with 27 cases observed in the Policlinico Umberto I Emergency Department (Rome) over the period from March 2003 to May 2005. All patients were treated with the same diagnostic and therapeutic protocol: once the diagnosis of acute biliary pancreatitis had been made and the severity evaluated, patients presenting clinical or ultrasonographic signs of main biliary duct stones underwent ERCP within 72 hours of onset of symptoms. All patients then underwent a standard-technique laparoscopic cholecystectomy during the same hospital stay, and whenever ERCP had not been performed preoperatively, an intraoperative cholangiography was performed at the time of surgery.

[Thyroid surgery: total and partial resection. Analysis of complications and a review of the literature].

The authors review the recent international literature relating to approximately 36,800 cases of thyroid surgery, analysing the complications associated with total thyroidectomy versus partial resection of the thyroid, with a view to drawing up lines of conduct in terms of indications for surgery of benign disease and suggestions on surgical technique to reduce complications such as recurrent laryngeal nerve injuries (transient and definitive), hypocalcaemia (transient and definitive) and superior laryngeal nerve injuries.

[Classification and management of gynecologic acute abdomen at a secondary level hospital emergency department].

This study retrospectively evaluates the preoperative work-up and the classification and operative treatment of acute abdomen caused by gynaecological disorders in emergency admissions to our department. All female patients admitted in the emergency setting and operated on for gynaecological acute abdomen in our emergency department over the period from 1997 to 2002 were included in the study. A total of 103 patients were identified (54 undergoing emergency operations, 9 operated on within 72 hours, and 40 managed conservatively with medical therapy.

[Conservative approach to IV grade renal trauma].

A case of grade IV renal trauma is reported and the literature reviewed. A 29-year-old man was admitted in an emergency setting for a grade IV renal and splenic trauma as a result of a motorcycle accident. Since the patient was haemodynamically stable and the retroperitoneal haematoma was neither expanding nor pulsating, a conservative approach was adopted and the renal trauma was managed with interventional radiology.

[Multidisciplinary approach to the patient with multiple trauma: a case report].

A multidisciplinary approach to severe polytraumatized patient is very important for a rapid, uncomplicated recovery. Specialized centres with special beds, monitoring equipment, and a multidisciplinary team are required. The authors report a case of a 26-year-old man admitted to their department in an emergency setting for a crush injury (occupational trauma) of the lumbar, gluteal and perineal areas, complicated with septic shock and gas gangrene of the injured areas.
