Adventitious bursitis is an inflammatory condition affecting bursae. Distinct from primary or infectious bursitis, adventitious bursitis typically develops secondary to conditions such as rheumatoid arthritis, gout, or repetitive joint overuse. The resulting inflammation can lead to pain, swelling, and restricted mobility, significantly impacting patients' quality of life.

Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection.

Introduction: Healthcare-associated infections (HAIs) are common in intensive care unit (ICU) patients and may cause devastating consequences. However, the prevalence of HAI and its effects on in-hospital mortality among critically ill COVID-19 patients is ambiguous. We determined the prevalence of HAI and the rate of mortality in critically ill COVID-19 patients and compared it with pre-pandemic ICU patients.

Article Synopsis
  • The study aimed to investigate the effects of Dropped Head Syndrome (DHS) on functional status and body image in Head and Neck Cancer (HNC) patients while also examining the link between head and neck lymphedema (HNL) and DHS, a first in existing literature.
  • A total of 47 HNC patients aged 18 to 75 were assessed, using specific staging and quality of life scales to evaluate the impact of DHS and lymphedema on body image and function.
  • Results indicated significant correlations between body image scores and various factors such as age, surgical history, and lymphedema stages, highlighting the need for early diagnosis and proactive management to enhance quality of life for affected

Objective: To investigate the impact of Complex Decongestive Therapy (CDT) on the severity of frailty and quality of life in individuals suffering from postmastectomy lymphedema syndrome.

Methods: Participants who met the inclusion criteria were informed about CDT and informed consent was obtained. Edmonton Frailty Scale (EFS), extremity volüme (EV), lymphedema stage(LS), EQ-5D General Quality of Life Scale (EQ-5D-5L), and Quick Disabilities of Arm, Shoulder, and Hand (DASH) scores were evaluated by the same physician before and after treatment.

The need to develop green and cost-effective industrial catalytic processes has led to growing interest in preparing more robust, efficient, and selective heterogeneous catalysts at a large scale. In this regard, microwave-assisted synthesis is a fast method for fabricating heterogeneous catalysts (including metal oxides, zeolites, metal-organic frameworks, and supported metal nanoparticles) with enhanced catalytic properties, enabling synthesis scale-up. Herein, the synthesis of nanosized UiO-66-NH was optimized via a microwave-assisted hydrothermal method to obtain defective matrices essential for the stabilization of metal nanoparticles, promoting catalytically active sites for hydrogenation reactions (760 kg·m·day space time yield, STY).

Malignant peripheral nerve sheath tumors are soft tissue sarcomas originating from peripheral nerves. They are more frequently diagnosed in individuals with neurofibromatosis and tend to affect young men more often than women. The most common sites for these tumors within the peripheral nerve sheath are in the pelvis and the distal femur.

Undifferentiated pleomorphic sarcoma (UPS), which was previously known as malignant fibrous histiocytoma (MFH), rarely presents in the abdomen, and sarcomatosis due to UPS has not yet been reported in the literature. Here, we present a 62-year-old man who had abdominal sarcomatosis due to UPS with a poor prognosis.

Article Synopsis
  • Hyperthermia is a cancer treatment method that heats tumor cells above 42 °C to induce cell death and has gained attention for its selectivity.
  • A new hybrid nanostructure was developed, combining plasmonic gold nanorods with a silica shell and iron oxide nanoparticles to respond to both magnetic fields and near-infrared light.
  • This innovative design allows for targeted separation of specific cell populations and enhanced photothermal heating, proving effective in treating human glioblastoma cells.

The goal of this study was to biomechanically and morphologically research both the impact of mobile phone like radiofrequency radiations (RFR) on the tibia and the effects on skeletal muscle through oxidative stress parameters. Fifty-six rats (200-250 g) were put into groups: healthy sham (n = 7), healthy RFR (900, 1800, 2100 MHz) (n = 21), diabetic sham (n = 7) and diabetic RFR (900, 1800, 2100 MHz) (n = 21). Over a month, each group spent two hours/day in a Plexiglas carousel.

Objective: The aim of this study is to investigate the roles of pre- and post- treatment quantitative fluorine-18-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) parameters including maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) and their rate of change in predicting pathological complete response (pCR) in patients with local and locally advanced invasive breast cancer receiving neoadjuvant chemotherapy (NAC).

Subjects And Methods: Ninety-eight patients who received NAC after being diagnosed with local and locally advanced invasive breast cancer between January 2017 and September 2021 were retrospectively included in our study. Molecular subtypes of all patients were determined.

The Stöber method is one of the most important and fundamental processes for the synthesis of inorganic (nano)materials but has the drawback of using a large amount of organic solvent. Herein, ethanol was used as an example to explore if the organic solvent in a typical Stöber method can be omitted. It was found that ethanol increases the particle size of the obtained silica spheres and aids the formation of uniform silica particles rather than forming a gel.

Objective: Earlier detection and timely interventions against cancers are well known to reduce the morbidity and mortality. Screening programs provide opportunity to detect cancers as early as precancerous stages. Cancers of cervix of uterus are one of the cancers that have widely applicable screening methods and are one of the three cancer types that have population-based screening program in Turkiye.
