Biopsy-proven BK virus nephropathy in renal transplant recipients: A multi-central study from Turkey (BK-TURK STUDY).

Aim: BK polyomavirus infection is a challenging complication of renal transplantation. The management is not standardized and is based on reports from transplantation centers' experiences, usually with small sample sizes. Therefore, we aimed to present our countrywide experience with BK virus nephropathy (BKVN) in renal transplant recipients.

Long-Term Outcomes of Kidney Paired Donation Transplantation: A Single Center Retrospective Cohort Study.

Background: This study aimed to compare the kidney paired donation (KPD) program recipients with the traditional living donor kidney transplantation (LDKT) recipients regarding patient and graft survival.

Methods: We retrospectively analyzed 141 recipients of the KPD program and 141 classic LDKT recipients that we matched for age and sex as controls between July 2005 and June 2019. We compared the 2 transplant groups for patient and kidney survival using the Kaplan-Maier test.

Acute kidney injury in Turkey: epidemiological characteristics, etiology, clinical course, and prognosis.

Background: This study aimed to evaluate the etiologies, comorbidities, and outcomes of acute kidney injury (AKI) in Turkey and determine any potential differences among different geographical parts of the country.

Methods: This prospective observational study was conducted by the Acute Kidney Injury Working Group of the Turkish Society of Nephrology. Demographical and clinical data of patients with AKI at the time of diagnosis and at the 1 week and 1, 3, and 6 months of diagnosis were evaluated to determine patient and renal survival and factors associated with patient prognosis.

The Longitudinal Evolution of Post-COVID-19 Outcomes Among Hemodialysis Patients in Turkey.

Introduction: Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period have not been published extensively.

Methods: We conducted a national, multicenter observational study that included adult maintenance HD patients recovered from confirmed COVID-19.

The impact of COVID-19 pandemic on glycemic control in patients with diabetes mellitus in Turkey: a multi-center study from Kocaeli.

Aims: The aim of this study is to determine the impact of the COVID-19 pandemic on the management and disease control of the patients with diabetes mellitus in Kocaeli.

Methods: This study was carried out in six leading central hospitals in five major districts of Kocaeli. The study was conducted between June 2020 and November 2020.

Blood pressure, inflammation, and quality of life in patients treated with different renal replacement therapies.

Our aim was to determine the relationship between the modality of renal replacement therapy and inflammation markers, BP control, and quality of life (QoL). Sixteen hemodialysis, 17 peritoneal dialysis patients, and 27 kidney transplant receivers (KTr) have been included in this study. Short Form-36 (SF-36) for the evaluation of QoL and ambulatory BP monitoring were performed on the same day.

Comparison of erectile function in patients with end-stage renal disease receiving haemodialysis and kidney transplantation.

To investigate the frequency and risk factors of ED in haemodialysis patients (HDps) and kidney transplantation (KTx) recipients (KTxRs). HDps and KTxRs between the ages of 18-65 were compared in terms of ED. IEFF-15 (International Index of Erectile Function) score was used to evaluation of ED.

Renal Tubular Acidosis in Patients with Systemic Lupus Erythematosus.

Objective: Renal tubular acidosis (RTA) is a clinical manifestation that occurs with insufficiency in restoring bicarbonate or disruption in hydrogen ion elimination as a result of a disruption in tubulus functions, causing normal anion gap-opening metabolic acidosis. In the present study, we aimed to investigate the prevalence of RTA in the largest systemic lupus erythematosus (SLE) patient population to date.

Materials And Methods: SLE patients, who were followed up in 2 different healthcare centers, were included.

Does altitude affect blood gases in hemodialysis patients?

Introduction: This study aimed to determine whether predialysis blood gases is affected by altitude differences in hemodialysis patients with arteriovenous fistulas living in Turkey at three different altitudes.

Methods: Patients' predialysis blood gases were compared by standardizing both arterial blood gases collections and working methods for patients undergoing hemodialysis using a dialysate with the same properties at altitudes of 30 m (sea level), 1020 m (moderate altitude), and 1951 m (high altitude).

Findings: Blood gases disorders were detected in 32 (82.

Prevalence of cardiac arrhythmia and risk factors in chronic kidney disease patients.

Chronic kidney disease (CKD) patients have a high risk for cardiac arrhythmia. This study aimed to investigate the prevalence of cardiac arrhythmia in CKD patients and to evaluate the relationship between arrhythmia and biochemical and echocardiographic parameters. CKD patients between 18 and 80 years of age were enrolled from the nephrology outpatient clinic.

Is the preoperative MPV value related to early thrombus formation in microvascular anastomosis?

Objective: One of the most common encountered problems in free flap surgeries is anastomotic thrombosis. The mean platelet volume (MPV) may indicate the concentration of intra-platelet proactive substances and the thrombogenic potential of the platelets. MPV is used as a clinical monitoring index in routine blood counts, it has not yet been effectively used in free flap surgery.

Prolonged hypophosphatemia following parathyroidectomy in chronic hemodialysis patients.

Secondary hyperparathyroidism (SHPT) is a common problem in patients with end-stage renal disease. In cases with severe and resistant SHPT, surgical parathyroidectomy (PTX) is recommended. Hungry bone syndrome (HBS) following surgical PTX is most often associated with hypocalcemia and hypophosphatemia.

Expression of p53, Ki67, epidermal growth factor receptor, transforming growth-factorα, and p21 in primary and secondary hyperparathyroidism.

Background: Secondary hyperparathyroidism (SH) is major problem in chronic renal failure. There are studies to examine proliferation and apoptosis associated biomarkers expressions in parathyroid lesions to reveal specific features. In this study, we evaluated the expression of some growth factors and their receptors in parathyroid gland of patients with SH or primary hyperparathyroidism (PH).

Lactic acidosis induced by metformin in a chronic hemodialysis patient with diabetes mellitus type 2.

Metformin is a biguanide group oral antidiabetic drug used for the treatment of type 2 diabetes mellitus. Nausea, vomiting, diarrhea, abdominal pain, and anorexia are the most common adverse effects encountered during treatment. Lactic acidosis is a serious side effect seen with metformin use, and while the incidence of lactic acidosis is similar to other oral antidiabetics, metformin is not recommended to patients with certain risk factors, such as cardiovascular, pulmonary, and renal and liver failure.

Milk alkali syndrome induced by calcitriol and calcium bicarbonate in a patient with hypoparathyroidism.

The milk-alkali syndrome (MAS) was a common cause of hypercalcemia, metabolic alkalosis, and renal failure in the early 20(th) century. This syndrome was first recognized secondary to treatment of peptic ulcer disease with milk and absorbable alkali. Its incidence fell after the introduction of H2-blocker and proton pump inhibitor.

An unusual case of recurrent endometrial cancer presented with isolated cervical lymph node metastasis.

Endometrial cancer (EC) is the most common malignancy of the female genital tract. Lymph node involvement is one of the major prognostic factors. Therefore, pelvic and paraaortic lymph nodes dissection is a part of the surgical management of these patients.
