Long-Term Effects of Alemtuzumab on CD4+ Lymphocytes in Multiple Sclerosis Patients: A 72-Month Follow-Up.

Introduction: Alemtuzumab is highly effective in the treatment of patients with relapsing multiple sclerosis (PwRMS) and selectively targets the CD52 antigen, with a consequent profound lymphopenia, particularly of CD4+ T lymphocytes. However, the immunological basis of its long-term efficacy has not been clearly elucidated.

Methods: We followed up 29 alemtuzumab-treated RMS patients over a period of 72 months and studied the immunological reconstitution of their CD4+ T cell subsets by means of phenotypic and functional analysis and through mRNA-related molecule expression, comparing them to healthy subject (HS) values (rate 2:1).

The use of antenatal corticosteroids for fetal maturation: clinical practice guideline by the WAPM-World Association of Perinatal Medicine and the PMF-Perinatal Medicine foundation.

This practice guideline follows the mission of the World Association of Perinatal Medicine in collaboration with the Perinatal Medicine Foundation, bringing together groups and individuals throughout the world, with the goal of improving the use of antenatal corticosteroids (ACS) for fetal maturation. In fact, this document provides further guidance for healthcare practitioners on the appropriate use of ACS with the aim to increase the timely administration and avoid unnecessary or excessive use. Therefore, it is not intended to establish a legal standard of care.

Multiple Coronary Fistulas as a Rare Cause of Stable Angina Pectoris.

Congenital coronary artery-left ventricular multiple microfistulas (CA-LVMMFs) are rare anomalies in adults. They are more often found in female patients, and they usually originate from the distal segments of the coronary arteries, but they can originate from a proximal segments of a coronary arteries, and these patients are likely to be identified and treated in the pediatric age group. They are mostly asymptomatic.

Preanalytical quality improvement - an interdisciplinary journey, on behalf of the European Federation for Clinical Chemistry and Laboratory Medicine (EFLM) Working Group for Preanalytical Phase (WG-PRE).

Since the beginning of laboratory medicine, the main focus was to provide high quality analytics. Over time the importance of the extra-analytical phases and their contribution to the overall quality became evident. However, as the initial preanalytical processes take place outside of the laboratory and mostly without its supervision, all professions participating in these process steps, from test selection to sample collection and transport, need to engage accordingly.

Treatment of Sciatica and Lumbar Radiculopathy with an Intervertebral Foramen Opening Protocol: Pilot Study in a Hospital Emergency and In-patient Setting.

Aims: Perform a pilot study of a static nerve root foramen opening protocol for lumbar radiculopathy from disc hernia in an emergency hospital setting to establish if patients could execute the protocol, consistency would occur across outcomes, superior outcomes would occur in the experimental group, and if the protocol would be safe.

Methods: Patients with sciatica arrived of their own volition at the local emergency hospital department, were admitted for care and were randomized into two groups: 1) control (n = 10): forward bending, walking, and medication; and 2) experimental (n = 10) as control subjects, plus a static lumbar foramen opening protocol using flexion and contralateral lateral flexion (side-lying). Outcomes were back and leg pain (i.

Characterisation of subchondral bone repair following transplantation of bioreactor-manufactured autologous osteochondral graft in a sheep model.

To date, no single approach to the treatment of osteochondral defects has resulted in satisfactory long-term outcomes, especially in a young and active human population. Emerging innovative tissue engineering strategies, including the use of composite scaffolds, novel cell sources and bioreactors, have shown promising results. However, these techniques need to be validated in translational animal models before they can be implemented in clinical practice.

The New Face of the Switch Flap in the Reconstruction of a Large Upper Eyelid Defect.

Reconstruction of a large defect after the removal of a massive malignant upper lid tumor is still a challenge in oculoplastic surgery. Our method of choice is Mustardé switch flap. Due to the lack of Mohs micrographic surgery and frozen section technique as well as waiting time of two weeks for histopathological results, we made modifications enabling us to reexcise in case of positive margins: the width of the pedicle of the flap was 7 mm allowing the length of the flap to be increased if needed, the lids were closed with temporary lateral tarsorrhaphy to protect the eye, and the lower lid is finally reconstructed in the second stage of the procedure.

The aim of this research was to explore the professional and ethical attitudes and experiences of medical professionals on treatment of end-of-life patients in ICUs in the Republic of Croatia.

Methods: A cross-sectional study was conducted among physicians and nurses working in surgical, medical, neurological, and multidisciplinary ICUs in the total of 9 hospitals throughout Croatia using a questionnaire with closed and open type questions.

Prenatally detected encephalocele associated with a novel pathogenic TCTN3 variant: A case report and literature review.

Primary cilia are a component of almost all vertebrate cells with a crucial role in sensing and transducing environmental signals during tissue development. Their dysfunction is known as ciliopathies and can manifest with a wide spectrum of clinical disorders. Overlapping features and molecular heterogeneity of ciliopathies make diagnoses distinctly challenging.

How to Distinguish Idiopathic Achalasia from Pseudoachalasia?

Achalasia is a disorder characterized by insufficient relaxation of the lower esophageal sphincter and absent peristalsis. It is usually primary (idiopathic) achalasia, but it can also be secondary achalasia (pseudoachalasia). With a review of the literature, epidemiological data was gathered on achalasia in this paper, and followed up with presented etiopathogenetic mechanisms of achalasia.

Weather patterns and occurrence of epileptic seizures.

Background: The results of various studies that have so far evaluated the influence of meteorological conditions on seizures are often divergent. No studies have been performed so far that evaluate the possible correlation between the occurrence of seizure-related events, surface and upper level atmospheric conditions and biometeorological forecasts. The aim of this study is to investigate those interactions.

Extensive Abdominal Skin Necrosis Following Anterior Component Separation for a Large Ventral Hernia: A Case Report.

Hernia surgery is one of the most common operative procedures, performed in about 20 million cases per year all over the world, with ventral hernia accounting for about 30% of the cases. Although the introduction of the anterior component separation (ACS) method, popularized primarily by Oscar Ramirez, has greatly facilitated the closure of the largest abdominal wall defects, the 30-year experience in this technique has pointed to the risk of ischemic skin complications consequential to the major subcutaneous tissue dissection required. The aim of this case presentation of a patient who developed extensive necrosis of the abdominal wall skin following ACS procedure is to emphasize the importance of preserving rectus abdominis perforator blood vessels in order to preserve skin vitality.

Polychromatic Flow Cytometric Analysis of Stromal Vascular Fraction from Lipoaspirate and Microfragmented Counterparts Reveals Sex-Related Immunophenotype Differences.

Mesenchymal stem/stromal cells or medicinal signaling cells (MSC)-based therapy holds promise as a beneficial strategy for treating knee OA (osteoarthritis), but there is no standardized protocols nor mechanistic understanding. In order to gain a better insight into the human MSC from adipose tissue applied for autologous OA treatment, we performed extensive comparative immunophenotyping of the stromal vascular fraction from lipoaspirate or microfragmented lipoaspirates by polychromatic flow cytometry and investigated the cellular components considered responsible for cartilage regeneration. We found an enrichment of the regenerative cellular niche of the clinically applied microfragmented stromal vascular fraction.

Preventive CCL2/CCR2 Axis Blockade Suppresses Osteoclast Activity in a Mouse Model of Rheumatoid Arthritis by Reducing Homing of CCR2 Osteoclast Progenitors to the Affected Bone.

Detailed characterization of medullary and extramedullary reservoirs of osteoclast progenitors (OCPs) is required to understand the pathophysiology of increased periarticular and systemic bone resorption in arthritis. In this study, we focused on identifying the OCP population specifically induced by arthritis and the role of circulatory OCPs in inflammatory bone loss. In addition, we determined the relevant chemokine axis responsible for their migration, and targeted the attraction signal to reduce bone resorption in murine collagen-induced arthritis (CIA).

COVID-19: The Impact on Cardiovascular System.

SARS-CoV-2 has been circulating in population worldwide for the past year and a half, and thus a vast amount of scientific literature has been produced in order to study the biology of the virus and the pathophysiology of COVID-19, as well as to determine the best way to prevent infection, treat the patients and eliminate the virus. SARS-CoV-2 binding to the ACE2 receptor is the key initiator of COVID-19. The ability of SARS-CoV-2 to infect various types of cells requires special attention to be given to the cardiovascular system, as it is commonly affected.

Klatskin-Mimicking Lesions.

Altemeier-Klatskin tumor is a perihilar cholangiocarcinoma that occurs within 2 cm of the confluence of the right and left hepatic duct at the hepatic hilum and accounts for 50-70% of all cholangiocarcinomas cases. Although imaging techniques have come very far today, this entity can still be very challenging to diagnose as there are many lesions that can mimic Klatskin tumor. In this review, we will present the most common Klatskin-mimicking lesions.
