Four strains of green microalgae (, , , and ) were compared to determine growth and pigment composition under photoautotrophic or heterotrophic conditions. Batch growth experiments were performed in multicultivators with online monitoring of optical density. For photoautotrophic growth, light-limited (CO-sufficient) growth was analyzed under different light intensities during the exponential and deceleration growth phases.

Background: Endoscopic ultrasound-guided biliary drainage (EUS-BD) was associated with better clinical success and a lower rate of adverse events (AEs) than fluoroscopy-guided percutaneous transhepatic biliary drainage (PTBD) in recent single center studies with mainly retrospective design and small case numbers (< 50). The aim of this prospective European multicenter study is to compare both drainage procedures using ultrasound-guidance and primary metal stent implantation in patients with malignant distal bile duct obstruction (PUMa Trial).

Methods: The study is designed as a non-randomized, controlled, parallel group, non-inferiority trial.

Considering the importance of microalgae as a promising feedstock for the production of both low- and high-value products, such as lipids and pigments, it is desirable to isolate strains which simultaneously accumulate these two types of products and grow in various conditions in order to widen their biotechnological applicability. A novel freshwater strain from the genus was isolated in Belgium. Compared to other species, the isolate presented rapid growth in phototrophy, dividing 3.

Article Synopsis
  • The study examines the safety of combining anterior cruciate ligament (ACL) and anterolateral ligament reconstruction (ACL + ALLR) compared to isolated ACL reconstruction (ACLR) in terms of adverse outcomes following surgery.
  • Researchers conducted a randomized controlled trial, including 224 patients with an average follow-up period of about 12 months, focusing on complications, reoperations, and knee function scores.
  • Findings showed a higher rate of reoperations for cyclops syndrome in the ACLR group (8.9%) compared to the ACL + ALLR group (0%), while other outcomes like graft rupture rates and pain levels were not significantly different between the two groups.

Article Synopsis
  • Primary cutaneous CD4 small/medium T-cell lymphoproliferative disorder (PCSMLPD) is a newly identified condition classified by the WHO in 2017, characterized by a slow-growing, localized skin lesion primarily in adults (mean age 59).
  • In a study of 60 patients, the majority presented with nodules on the head and neck, and 31.9% experienced spontaneous regression, indicating a generally indolent disease course over an average follow-up of 16.6 months.
  • Histologically, PCSMLPD often shows extensive nodular or diffuse infiltrates in the dermis and varying patterns of T-follicular helper lineage markers, but commonly

Lateral extraarticular procedures (LEAPs) in the anterior cruciate ligament (ACL)-injured knee were widely abandoned in the 1990s but have seen a recent resurgence. The aim of this review was to demonstrate that anterolateral ligament reconstruction (ALLR) is associated with evidence of significant advantages and no evidence of historical concerns. A narrative review of the literature was performed.

Purpose: To perform a systematic review of contemporary studies reporting clinical outcomes of primary anterior cruciate ligament (ACL) repair to determine whether these studies demonstrate any significant benefit of ACL repair and whether there is evidence of a deterioration of mid-term outcomes as seen in historical data.

Methods: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A PubMed search using the keywords "repair" AND "Anterior Cruciate Ligament" was performed (limits: English language, publication date between January 1, 2014, and January 13, 2019).

Background: Cyclops syndrome is characterized by a symptomatic extension deficit attributed to impingement of a cyclops lesion within the intercondylar notch. The syndrome is an important cause of reoperation after anterior cruciate ligament reconstruction (ACLR). It has been suggested that remnant-preserving ACLR techniques may predispose to cyclops syndrome, but there is very limited evidence to support this.

Background: Professional athletes are reported to be at greater risk of septic arthritis (SA) after anterior cruciate ligament reconstruction (ACLR) than the nonprofessional population. However, this finding has been controversial, and confusion has arisen in the literature owing to the underpowering of previous studies.

Purpose/hypothesis: The purpose was to report the differences in the rate of SA after ACLR in a large series of patients and to perform pooled data analysis including previously published studies.

Background: Primary immunodeficiencies are rare and frequently life-threatening conditions in the first year of life. They may present with isolated skin manifestations and the absence of other clinical signs may delay diagnosis and management of the disease. Herein we describe a case of IPEX syndrome (Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked syndrome) that illustrates this situation.

Background: Modular stems have been widely studied as they allow intraoperative adjustments (offset, anteversion, limb length) to better restore hip biomechanics. Many authors reported outcomes of revision total hip arthroplasty (THA) using modular stems with metaphyseal-diaphyseal junctions, however, little is known about modular neck femoral stems (MNFS) with metaphyseal-epiphyseal junctions. We therefore aimed to report outcomes and implant survival of a MNFS in a consecutive series of revision THA at a minimum follow-up of 5 years.
