Mutation Case Report and Literature Review.

Mol Syndromol

December 2024

Division of Pediatric Metabolism, Dr. Sami Ulus Maternity and Child Health Training and Research Hospital, University of Health Sciences, Ankara, Turkey.

Introduction: Mutations in the RMND1 gene that cause defects in the mitochondrial respiratory chain result in a highly variable phenotypic presentation. The protein required for meiotic nuclear division 1 homolog (RMND1) is localized to the inner mitochondrial membrane and is encoded by the nuclear genome.

Case Presentation: We report a new patient from a consanguineous family who was severely affected by a previously described combined oxidative phosphorylation deficiency 11 and was treated rapidly due to early diagnosis.

December 2024

Division of Pediatric Allergy and Immunology, Faculty of Medicine, Marmara University, Istanbul, Turkey; Istanbul Jeffrey Modell Diagnostic and Research Center for Primary Immunodeficiencies, Istanbul, Turkey; Isil Berat Barlan Center for Translational Medicine, Istanbul, Turkey. Electronic address:

Article Synopsis
  • STAT3 gain-of-function disease causes issues like immune system overactivity and growth problems, but long-term treatment with the JAK inhibitor ruxolitinib has shown promise in symptom relief.
  • The study monitored clinical and immune responses of four patients over a year, noting significant changes in T cell populations and the normalization of blood cell profiles, which were previously dysregulated.
  • Ruxolitinib treatment not only managed symptoms but also modified harmful immune cell characteristics and reduced certain auto-reactive T-cell clones, suggesting a potential pathway to better control the disease's impact.

Clin Radiol

January 2025

Istanbul University Faculty of Medicine, Department of Radiology, Istanbul, Turkey. Electronic address:

Hydatidosis is an endemic parasitic disease that can occur in almost any part of the body. It presents in two different forms according to the type of tapeworm: Echinococcus granulosus (hydatid disease [HD]) and Echinococcus multilocularis (alveolar HD). Radiological imaging can reveal the type of cyst, disease activity and progression, and complications, with features depending on the HD stage, the organ involved, and complications.

Article Synopsis
  • People are increasingly exposed to electromagnetic radiation (EMR) from mobile phones, raising concerns about potential health effects, particularly on reproduction.
  • A study tested the effects of EMR (4.5 GB; 2600 MHz) on rat ovaries by dividing 18 female rats into control, stand-by, and dialing groups over 8 weeks.
  • The results showed follicular degeneration and increased expression of specific proteins related to cell death (Caspase-3) and cell survival (Beclin-1) in the EMR-exposed groups, suggesting that mobile phone radiation can harm ovarian health.

Current guidelines recommend adding long-acting muscarinic antagonists (LAMAs) in patients with uncontrolled asthma, despite the use of moderate to high doses of inhaled steroid-long-acting beta agonists (ICS/LABA). This study aims to analyze the factors related to the prescription of add-on LAMA in clinical practice for asthma patients, shedding light on physicians' preferences. This study included adult asthma patients on add-on LAMA and ICS/LABA monitored for at least one year in a national registry comprising 2053 asthmatics.

Article Synopsis
  • Chronic obstructive pulmonary disease (COPD) often leads to hospital readmissions, with a study involving 415 patients in Turkey revealing significant readmission rates of 42.4% within 30 days and 46% within 90 days after severe exacerbations.
  • Key risk factors for 30-day readmissions include high anxiety and depression scores, a history of severe exacerbations, hospital-acquired pneumonia, and frequent antibiotic use.
  • For 90-day readmissions, factors such as severe heart regurgitation, multiple moderate exacerbations, immunosuppression, and being hospitalized via the emergency department were significant contributors.

Background: Poststroke osteoporosis, particularly of the hip, and an increased risk of fractures due to accidental falls are well known in people with stroke. Only a few of the current stroke guidelines recommend bone mineral density (BMD) measurements during follow-up in this population and measurements are often performed unilaterally.

Objectives: To compare femoral hip BMD between fallers and nonfallers among patients with stroke, while also assessing differences in balance, mobility, fear of falling, and exploring discrepancies between paretic and nonparetic sides within each group.

Impaired development of memory B cells and antibody responses in humans and mice deficient in PD-1 signaling.

Immunity

December 2024

Garvan Institute of Medical Research, Darlinghurst, NSW 2010, Australia; School of Clinical Medicine, Faculty of Medicine and Health, UNSW Sydney, Sydney, NSW 2052, Australia; Clinical Immunogenomics Research Consortium Australasia (CIRCA), Darlinghurst, NSW 2010, Australia. Electronic address:

Article Synopsis
  • T follicular helper (Tfh) cells, which are important for antibody production, rely heavily on the immunoreceptor PD-1, and its deficiency leads to weakened Tfh functions and impaired immune responses in mice.
  • Individuals lacking PD-1 or PD-L1 demonstrate fewer memory B cells and diminished antibody responses, highlighting the critical role of these molecules in immune system functionality.
  • PD-1 influences both the intrinsic and extrinsic aspects of B cell memory and antibody production, suggesting that disruptions in PD-1 signaling can lead to complications in immune responses, especially during anti-PD-1-PD-L1 therapies.

Article Synopsis
  • The study investigates oxidative stress levels in ICU patients by measuring total oxidant level (TOS), total antioxidant level (TAS), and oxidative stress index (OSI) before treatment starts.
  • In total, 153 patients were analyzed, along with 60 healthy controls, revealing significantly higher TOS and OSI in patients, indicating elevated oxidative stress.
  • The findings show that patients also had increased levels of inflammation markers like ferritin, C-reactive protein (CRP), and procalcitonin (PCT), suggesting a strong correlation between oxidative stress and inflammation in critically ill individuals.

It is known that critical illness and associated neuromuscular problems begin to appear in patients hospitalized in the intensive care unit (ICU) for more than a week. The goal of this study was to research the role of hydroxychloroquine (HCQ) in the treatment of cytokine storm and critical illness neuromyopathy (CINM) in a rat sepsis model. Rats were assigned into three groups, and a feces intraperitoneal-injection group (FIP) procedure was carried out on 30 rats to induce a model of sepsis for critical illness polyneuromyopathy (CINM).

Article Synopsis
  • The study aimed to assess the reliability of placental volume and MRI indicators in predicting placenta accreta spectrum (PAS) and severe peripartum hemorrhage (SPPH) in women with complete placenta previa.
  • Involving 216 pregnant women, data were analyzed by two radiologists who independently reviewed MRIs of 150 cases delivered in the third trimester, focusing on placental volume, cervical canal length, and dilation.
  • Results indicated significant risk factors for PAS and SPPH, particularly lower cervical canal length and increased cervical dilation, confirming cervical canal length as a key independent predictor for both conditions.
