The most common cause of rhabdomyolysis is trauma. In the presence of rhabdomyolysis attacks triggered by heavy exercise and fever, hereditary causes should be investigated. In our study, a case was presented that developed rhabdomyolysis and acute kidney injury due to carnitine palmitoyltransferase 2 (CPT2) deficiency and then required hemodialysis treatment.

Purpose: Obstructive Sleep Apnea Syndrome (OSAS) is considered a notable independent risk factor for cardiometabolic disorders. The current study aimed to investigate the efficacy of new anthropometric indices, A Body Shape Index (ABSI) and the Body Roundness Index (BRI), in assessing cardiovascular risk (CVR) and cardiovascular disease (CVD) among OSAS patients and to compare them with traditional indices.

Materials And Methods: The records of 281 patients who consulted our sleep center were retrospectively reviewed.

Article Synopsis
  • The study explored the link between delirium and tryptophan (TRP) along with its metabolites in older critically ill patients (aged >60) admitted to an ICU, involving 120 participants.* -
  • Results showed that patients with delirium had significantly higher levels of kynurenine (KYN)/TRP and quinolinic acid (QA)/TRP ratios and lower TRP levels compared to those without delirium, with the KYN/TRP ratio being a strong predictor for delirium.* -
  • The findings suggest that measuring tryptophan and its metabolites within the first 24 hours of ICU admission may help identify patients at high risk for developing delirium.*

Introduction: Different data systems have been used to reach a common decision in the interpretation of chest computed tomography (CT) scans for the detection of COVID-19 infection. The aim of our study was to determine the usefulness of the COVID-19 Reporting and Data System (CO-RADS) for COVID-19 in patients undergoing hemodialysis.

Methods: We included 90 hemodialysis patients who underwent chest CT and had samples available for real-time reverse transcription-polymerase chain reaction (RT-PCR).

Objective: Patients with impaired glucose metabolism have increased thyroid volume and a higher prevalence of nodules. Yet, some studies show that there is an improvement in these thyroid parameters after diabetes treatment. Our observational study aimed to reveal the effect of treatment on thyroid function, thyroid volume, and the presence of nodules in newly diagnosed type 2 diabetes mellitus (T2DM) patients who were started on metformin treatment.

Context: Inflammation-related markers may predict cardiovascular diseases.

Objective: In this study, it was aimed to assess pentraxin-3 (PTX-3) levels and its relationship with carotid intima-media thickness (CIMT) and high-sensitive C-reactive protein (hsCRP) in patients with subclinical hypothyroidism.

Design: Prospective cross-sectional study.

Background: Although smoking is known to accelerate aging, the mechanisms by which this occurs have not been fully clarified. Serum-soluble α-Klotho (sαKl), antiaging, anti-inflammatory, and developing resistance to oxidative stress properties are known.

Aim: This study aimed to determine the relationship between cigarette smoking, sαKl (antiaging hormone), inflammation, and oxidative stress.

Ovarian cancer (OC) is the main cause of gynecological cancer mortality in most developed countries. microRNA (miR) expression dysregulation has been highlighted in human cancers, and miR-34a is found to be downregulated and associated with inhibition of tumor growth and invasion in several malignancies, including OC. The winged helix transcription factor forkhead box P1 (FOXP1) is reported as either an oncogene or tumor suppressor in various cancers.

Article Synopsis
  • COVID-19 can have heart-related effects, and there is limited research on how it impacts heart activity in hemodialysis patients after recovery.
  • The study included 55 hemodialysis patients to compare their ECG readings before and after COVID-19 recovery, focusing on parameters like the QT interval and its corrected values.
  • Results showed significant prolongation of the QTc and QTc dispersion after recovery, indicating an increased risk of arrhythmias in these patients.

Article Synopsis
  • The study aimed to compare the visceral adiposity index (VAI) levels among postmenopausal women with normal bone mineral density (BMD), osteopenia, and osteoporosis.
  • A total of 120 women aged 50 to 70 were included, and while waist circumference was higher in those with normal BMD compared to others, other health metrics like BMI and blood pressure showed no significant differences.
  • Results indicate that women with normal BMD had higher VAI levels than those with osteoporosis, suggesting a potential link between visceral fat and bone health, warranting further research.

  • - The study found that 42.5% of the 259 pre-dialysis CKD patients reported poor sleep quality, assessed using the Pittsburgh Sleep Quality Index (PSQI).
  • - Factors like age, body mass index (BMI), waist and hip circumferences, and depression levels were significantly correlated with sleep quality, indicating physical and mental health influences.
  • - The study concluded that correctable factors—specifically systolic blood pressure, hip circumference, and depression—were independently linked to poor sleep quality in these patients.

Introduction: The anti-aging protein Klotho levels are decreased, and Klotho deficiency is associated with cardiovascular diseases in patients with chronic kidney disease. There are recent studies about the relation between soluble Klotho levels and anemia. We aimed to investigate the correlation of anemia and hemoglobin variability with soluble Klotho levels in hemodialysis patients.

PURPOSE We aimed to evaluate whether the perfusion pattern from pretreatment hepatic artery perfusion scintigraphy (HAPS) in patients with liver malignancies can predict response to selective internal radiation therapy (SIRT). METHODS This retrospective study analyzed 152 consecutive patients treated with yttrium-90 (90Y) resin microspheres between April 2015 and July 2017. HAPS using single-photon emission computed tomography/computed tomography (SPECT/CT) with 99mtechnetium macroaggregated albumin (99mTc-MAA) was performed before SIRT.

Aim: During transurethral resection of bladder tumor (TUR-BT), adductor muscle spasms in varying degrees can be seen due to stimulation of obturator nerve if the tumor is in the inferolateral localization. This can cause some serious complications such as bladder perforation. We aim to show the effectiveness of obturator nerve block (ONB) to avoid the adductor muscle spasm in general anesthesia applied with laryngeal mask (LMA) without using muscle relaxant according to the spinal anesthesia method.

This paper evaluates the performance of eight tests with null hypothesis of cointegration on basis of probabilities of type I and II errors using Monte Carlo simulations. This study uses a variety of 132 different data generations covering three cases of deterministic part and four sample sizes. The three cases of deterministic part considered are: absence of both intercept and linear time trend, presence of only the intercept and presence of both the intercept and linear time trend.
