Background/objectives: Eculizumab is a first-line treatment for atypical hemolytic uremic syndrome (aHUS), and patients undergoing eculizumab therapy may become more susceptible to infection caused by (). While meningococcal vaccination is required for patients undergoing eculizumab therapy, there is limited knowledge about meningococcal carriage in children with aHUS. We aimed to evaluate (1) the prevalence of carriage, (2) serogroup distribution, and (3) the immunization status of children undergoing eculizumab treatment for aHUS.

Objective: This study aims to compare the impact of 3 surgical techniques-stand-alone cage placement (SAC), anterior cervical plate (ACP) fixation, and total disc replacement (TDR)-on cervical lordosis restoration and segmental height after anterior cervical discectomy at C5-6 level. To eliminate the effect of lordosis between different levels, patients operated on at the same level were included in the study. Restoring cervical lordosis is crucial for improving patient outcomes, including pain reduction and preventing mechanical complications.

Background: Echocardiographic right ventricular (RV) dysfunction is a strong risk determinant for prognosis in patients with heart failure (HF). Although parameters of RV systolic function are widely used to define RV dysfunction, there is scarce data to suggest these parameters are best suited to predict HF-related outcomes.

Aims: We aimed to understand which morphologic or functional parameters are most closely associated with short-term mortality and HF-related hospitalization in patients with HF.

Article Synopsis
  • The study investigated the role of sonic hedgehog (SHH) protein in the development of bladder and ureter smooth muscle in children with vesicoureteral reflux (VUR) after ureteroneocystostomy operations.
  • Researchers analyzed 28 ureterovesical junction segments from 19 children using Western Blot to measure SHH protein expression levels against β-Actin as a control.
  • Results indicated that while SHH was present, there was no significant correlation between SHH levels and the severity of VUR, suggesting that SHH may play a role in the condition's development rather than its severity.

Electronic address:

Article Synopsis
  • Hospital-acquired bloodstream infections (HA-BSI) in ICU patients can be life-threatening, and this study aimed to see how early adequate antibiotic treatment affects 28-day mortality rates for patients who survive at least one day after infection onset.
  • Using data from a multicenter study with 2,418 patients, researchers found that those who received adequate treatment within 24 hours had a lower 28-day mortality rate (32.8%) compared to those who were inadequately treated (40%).
  • The study concluded that inadequate antibiotic therapy within 24 hours contributes significantly to 28-day mortality, indicating that quicker treatment could greatly improve patient outcomes in cases of HA-BSI.

Objective: Primary hypophysitis might be challenging to diagnose, and there is a lack of evidence regarding optimal treatment strategies due to rarity of the disease. We aim to investigate the clinical features and compare the outcomes of different management strategies of primary hypophysitis in a large group of patients recruited on a nationwide basis.

Design: A retrospective observational study.

  • - The study investigates the link between altered sense of smell and protein-energy wasting (PEW) in patients with chronic kidney disease (CKD), particularly focusing on those with moderate-to-advanced stages and those undergoing maintenance hemodialysis (MHD).
  • - Researchers tested the smell abilities of 139 individuals using an odor identification test and assessed their nutritional status with a malnutrition inflammation score (MIS); results showed CKD patients had poorer odor scores and higher inflammation indicators compared to healthy controls.
  • - Although advanced CKD patients had significantly impaired olfactory function, the study found no strong statistical connection between their smell abilities and the severity of PEW, indicating that while both issues are prevalent, they may not directly impact each other

Developmental and epileptic encephalopathies (DEEs) feature altered brain development, developmental delay and seizures, with seizures exacerbating developmental delay. Here we identify a cohort with biallelic variants in DENND5A, encoding a membrane trafficking protein, and develop animal models with phenotypes like the human syndrome. We demonstrate that DENND5A interacts with Pals1/MUPP1, components of the Crumbs apical polarity complex required for symmetrical division of neural progenitor cells.

Introduction: Contribution of T helper 1 and 2 cells-related cytokines to pathogenesis of myasthenia gravis (MG) is well known. Recently, the contribution of follicular T helper (Tfh) and T helper 17 cells-related molecules to the pathogenesis has gained importance. In this study, we aimed to evaluate the changes in Tfh- and Th17-related molecules before and after rescue therapy in patients with myasthenic crisis (cMG) and to reveal the molecular differences between stable MG and cMG patients.

Background: The main complications seen in patients who have undergone modified radical mastectomy (MRM) are seroma, surgical site infection, hematoma, wound dehiscence, flap necrosis, and nerve damage. While these complications lead to some problems the most feared effect in the early period is that they cause a delay in adjuvant treatment. Incisional Negative Pressure Wound Therapy (iNPWT) decreases wound dehiscence by reducing oedema and tension, especially in the incision line.

The risk of ovarian malignancy is increasing in patients with a history of breast cancer. Thus, well-defined predictors of ovarian malignancy should be identified to determine surgical or conservative management of adnexal masses in women with breast cancer. This study aimed to clarify the predictors of malignant ovarian tumors in patients with breast cancer with an isolated adnexal mass.
