[Genomic Characterization of SARS-CoV-2 Isolates Obtained from Antalya, Türkiye].

Mikrobiyol Bul

October 2024

The University of Groningen, University Medical Center Groningen, Department of Medical Microbiology and Infection Prevention, Division of Clinical Virology, Groningen, Netherlands.

As the number of coronavirus diseases-2019 (COVID-19) cases have decreased and measures have started to be implemented at an individual level rather than in the form of social restrictions, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) still maintains its importance and has already taken its place in the spectrum of agents investigated in multiplex molecular test panels for respiratory tract infections in routine diagnostic use. In this study, we aimed to present mutation analysis and clade distribution of whole genome sequences from randomly selected samples that tested positive with SARS-CoV-2 specific real-time reverse transcription polymerase chain reaction (rRT-PCR) test at different periods of the pandemic in our laboratory with a commercial easy-to-use kit designed for next-generation sequencing systems. A total of 84 nasopharyngeal/oropharyngeal swab samples of COVID-19 suspected patients which were sent for routine diagnosis to the medical microbiology laboratory and detected as SARSCoV-2 RNA positive with rRT-PCR were randomly selected from different periods for sequence analysis.

The increasing antibiotic resistance in Pseudomonas aeruginosa, responsible for both community-acquired and hospital-acquired infections, is of global significance. The primary mechanisms contributing to resistance development in P.aeruginosa include the increased activity of efflux pumps, decreased permeability of outer membrane porins and the production of carbapenemases.

This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

Pyoderma Gangrenosum: A Nightmare for Breast Surgery-Two Case Reports.

Eur J Breast Health

January 2025

Department of General Surgery, Gülhane Training and Research Hospital, University of Health Sciences Turkey, Ankara, Turkey.

Pyoderma gangrenosum (PG) is a rare, chronic, neutrophilic dermatosis characterized by painful ulcers that are often misdiagnosed as wound infections. We report two cases of postsurgical PG following breast surgery: A 46-year-old woman with a non-healing ulcer after a breast biopsy and a 37-year-old woman with wound dehiscence after bilateral reduction mammoplasty. Both cases were initially managed with repeated debridements, antibiotics, and wound care without improvement.

University of Health Sciences Türkiye, Ulucanlar Eye Training and Research Hospital, Clinic of Ophthalmology, Ankara, Türkiye.

Cataract surgery is the most frequently performed surgery worldwide. Although it is an effective surgical treatment option for improving patients' visual acuity, various complications can occur postoperatively. One such complication is the presence of retained lens material in the anterior chamber, which can lead to intraocular inflammation, increased intraocular pressure, corneal edema, and endothelial cell loss.

This randomized controlled study was conducted to evaluate the effects of telephone-assisted breastfeeding monitoring on physiological jaundice, exclusive breastfeeding in the first six months, colic, breastfeeding success, and breastfeeding self-efficacy. Breastfeeding and infant care training were given to pregnant women by video calls (N = 54). Video call counseling was provided to the mothers in the intervention group (n = 27) every day for the first week after discharge and weekly until the 24th week, and the control group (n = 27) was only telephone called in follow-up weeks.

Objectives: The relationship between elevated ferritin levels and metabolic abnormalities in PCOS patients, and whether ferritin is a cause or a consequence, is still debated. This study aimed to evaluate the impacts of the fourth generation combined oral contraceptive containing ethinyl estradiol/drospirenone (EE 30 mcg/DRSP 3 mg), known for its favorable metabolic profile and lower side effect risk, on iron metabolism in PCOS patients, while also exploring the potential relationship between metabolic parameters and iron status.

Methods: The retrospective analysis was conducted on 81 women aged 18-45, diagnosed with PCOS according to the Rotterdam criteria and treated with EE/DRSP for six months.

Highly selective inhibitors of cyclin-dependent kinase 4 and 6 (CDK4/6is) have emerged as a standart of care for first- and second-line therapies in combination with endocrine therapy (ET) for HR+/HER2- metastatic breast cancer (MBC) patients. It has been reported that combination therapy is more effective than ET alone and is safe in elderly patients as well as young patients. Nevertheless, elderly and very old patients with HR+/HER2-MBC treated with CDK4/6 inhibitor (CDK4/6i) combinations are relatively underrepresented in randomized controlled trials.
