Evaluation of Imaging Findings in Patients with Pretransplant and Posttransplant Tertiary Hyperparathyroidism.

OBJECTIVES: Tertiary hyperparathyroidism, characterized by autonomous overproduction of parathyroid hormone, can be seen in patients with long-standing secondary hyperparathyroidism (pretransplant) or after renal transplant (posttransplant). Parathyroid scintigraphy and ultrasonography are the most commonly used imaging procedures for the preoperative localization of abnormal parathyroid glands. We aimed to evaluate imaging findings in pretransplant and posttransplant tertiary hyperparathyroidism. MATERIALS AND METHODS: This study included 32 patients with pretransplant tertiary hyperparathyroidism and 20 patients with posttransplant tertiary hyperparathyroidism. On parathyroid scintigraphy with technetium-99m sestamibi, early-phase and latephase images were acquired. Images were evaluated for the presence and the number of active foci and the degree of uptake on the late-phase image. The existence of an autonomous gland was based on latephase retention and was scored from 0 to 2 (retention score). On ultrasonography, the criteria threshold for autonomy was the maximum length of the largest gland ≥10 mm (ultrasonography score). RESULTS: On parathyroid scintigraphy, the most commonly observed pattern in the pretransplant group was positivity in ≥3 glands, and in the posttransplant group the most commonly observed pattern was positivity in 1 to 2 glands. In pretransplant and posttransplant groups, the criteria threshold for the presence of an autonomous parathyroid gland on parathyroid scintigraphy (grade 2 retention) was met in 26 (81%) and 9 (45%) patients and on ultrasonography in 25 (78%) and 10 (50%) patients, respectively. In the whole group of patients (n = 52), correlation existed between ultrasonography score and retention score. Glandular weight was correlated with both retention score and ultrasonography score. CONCLUSIONS: Higher numbers of detectable glands and the presence of parathyroid autonomy were more common in the pretransplant group. This might be explained by parathyroid gland involution after transplant. The results may also suggest that factors other than autonomy are responsible for posttransplant tertiary hyperparathyroidism.

Effect of acupressure applied to L4 point on the severity of fistula needle pain in patients: A randomised control trial.

BACKGROUND: Patients usually feel pain when a needle is inserted into the fistula. This acute pain can be relieved by acupressure, which is a nonpharmacological application method. OBJECTIVE: This study was designed to explore the effect of acupressure application to the Hegu point on the severity of acute pain caused by fistula needle insertion in patients with antecubital arteriovenous fistula. DESIGN: It is a randomised control study. PARTICIPANTS: The study was conducted with 32 intervention and 32 control patients, recruited from a dialysis centre of a foundation university in Turkey between October 2021 and January 2022. MEASUREMENTS: Acupressure was applied 3 min before needle placement in the fistula area of the patients in the experimental group. RESULT: While there was no decrease in the severity of acute pain during fistula needle insertion in the patients in the control group, there was a significant decrease in the mean acute pain severity scores experienced by the patients in the experimental group, whose Hegu point acupressure was applied. CONCLUSION: The results of this study support the effectiveness of Hegu point acupressure as an effective and low-cost way to reduce the acute pain of needle insertion put on dialysis patients with a fistula. In addition, the results provide a practical reference for acute pain management for dialysis nurses.

A rare case of granulomatosis with polyangiitis with involvement of the gastrointestinal system.

We report a rare case of a 37-year-old man with granulomatosis with polyangiitis (GPA) with gastrointestinal system (GIS) involvement who needed 526 units of blood and blood product transfusions and was followed up in the intensive care unit (ICU). GIS involvement due to GPA is a rare condition that increases morbidity and mortality of patients. Patients may require ultramassive blood product transfusions. Thus, patients with GPA can be admitted to ICUs because of massive hemorrhage due to multisystem involvement, and survival is achievable with meticulous care through a multidisciplinary approach.

Effects of Nutritional Knowledge of Informal Caregivers on Depression and Metabolic Outcomes of Hemodialysis Patients.

Chronic renal failure (CRF) makes significant changes in the life of patients and their families. A good family support has a positive effect on successful patients' adaptation to the treatment and compliance with dietary regimen. This study aimed to examine the effects of nutritional knowledge of informal caregivers on depression and metabolic outcomes of hemodialysis patients. This was a cross-sectional study conducted at Baskent University Hemodialysis Center with 116 hemodialysis patients and their informal caregivers. Findings revealed that the caregivers who were the couple of the patients had the highest nutritional knowledge level than the other caregivers (p < .05). The postgraduate caregivers were more likely to have high nutritional knowledge level than the others (p < .05). The inflammation marker of the patients was significantly lower in the group of caregivers with higher level (T3 group) of nutritional knowledge than the others (p < .05). The mean CES-D scores were also more likely to be low in T3 group than in the others (p < .05). These findings highlight that the nutritional knowledge of caregivers of hemodialysis patients may have an additional benefit on patients' nutritional management and metabolic outcomes.

A model for acute kidney injury in severe burn patients.

INTRODUCTION: In patients with severe burns, morbidity and mortality are high. One factor related to poor prognosis is acute kidney injury. According to the AKIN criteria, acute kidney injury has 3 stages based on urine output, serum creatinine level, and renal replacement therapy. In this study, we aimed to create a decision tree for estimating risk of acute kidney injury in patients with severe burn injuries. METHODS: We retrospectively evaluated 437 adult patients with ≥20% total burn surface area injury who were treated at the Baskent University Ankara and Konya Burn Centers from January 2000 to March 2020. Patients who had high-voltage burn and previous history of kidney disease were excluded. Patient demographics, medical history, mechanism of injury, presence of inhalation injury, depth of burn, laboratory values, presence of oliguria, need for renal replacement therapy, central venous pressure, and prognosis were evaluated. These data were used in a "decision tree method" to create the Baskent University model to estimate risk of acute kidney injury in severe burn patients. RESULTS: Our model provided an accuracy of 71.09% for risk estimation. Of 172 patients, 78 (45%) had different degrees of acute kidney injury, with 26 of these (15.1%) receiving renal replacement therapy. Our model showed that total burn surface area was the most important factor for estimation of acute kidney injury occurrence. Other important factors included serum creatinine value, burn injury severity score, hemoglobin value, neutrophil-to-lymphocyte ratio, and platelet count. CONCLUSION: The Baskent University model for acute kidney injury may be helpful to determine risk of acute kidney injury in burn patients. This determination would allow appropriate treatment to be given to high-risk patients in the early period, reducing the incidence of acute kidney injury.

Acoustic Radiation Force Impulse Elastography Findings of Achilles Tendons in Patients on Chronic Hemodialysis and in Renal Transplant Patients.

OBJECTIVES: The Achilles tendon, which is composed of tendinous parts of gastrocnemius and soleus muscles, is the strongest and the largest tendon in the human body. Chronic renal disease can lead to reduced physical activity and exercise capacity. Spontaneous rupture of the Achilles tendon can occur in patients with chronic renal failure, with recurrent microtraumas, hypoxia, and chronic acidosis as predisposing factors. Here, we assessed and compared the elastographic findings in the Achilles tendon using acoustic radiation force impulse elastography in patients on chronic hemodialysis, in renal transplant patients, and in healthy volunteers. MATERIALS AND METHODS: Our study included 25 patients on chronic hemodialysis, 25 renal transplant patients, and 25 healthy individuals (control group). The thickness and shear wave velocity of the Achilles tendons were measured bilaterally by ultrasonography and acoustic radiation force impulse elastography. RESULTS: The mean shear wave velocity was 3.67 m/s in the right and 3.64 m/s in the left Achilles tendon in the hemodialysis group. In the renal transplant group, the mean shear wave velocity was 4.29 and 4.25 m/s for the right and left Achilles tendon, respectively. In the control group, the mean shear wave velocity was 6.68 and 6.59 m/s, respectively for the right and left Achilles tendon. A statistically significant difference in shear wave velocities was shown among the groups (P < .05). CONCLUSIONS: Achilles tendons in patients with chronic renal failure and on hemodialysis were softer than in renal transplant patients and softer than in the control group. Chronic tendinopathy causes softening of the tendon. In the renal transplant group, stiffness of the Achilles tendon was increased versus the hemodialysis group but still softer than the control group, which could be explained as a positive clinical effect of renal transplant. Acoustic radiation force impulse elastography is an objective, easy, and noninvasive method to assess Achilles tendinopathy.

Liver and Kidney Transplant During a 6-Month Period in the COVID-19 Pandemic: A Single-Center Experience.

OBJECTIVES: With the declaration of COVID-19 as a pandemic, many studies have indicated that elective surgeries should be postponed. However, postponement of transplants may cause diseases to get worse and increase the number in wait lists. We believe that, with precautions, transplant does not pose a risk during pandemic. Here, we aimed to evaluate our transplant results, which we safely performed during a 6-month pandemic period. MATERIALS AND METHODS: Until September 2020, 3140 kidney and 667 liver transplants have been performed in our centers. We evaluated 38 kidney transplants and 9 liver transplants procedures performed during the pandemic (March 1 to September 2, 2020). Recipient and donor candidates were screened for COVID-19 with polymerase chain reaction and thoracic computed tomography. All recipients had routine immunosuppressive protocol. During hospitalization at our COVID-19-free transplant facility, we restricted the interactions during multidisciplinary rounds. RESULTS: During the pandemic, 38 kidney transplants with an average length of hospital stay of 8.1 days were performed. Mean serum creatinine values of recipients were 0.91, 0.86, and 0.74 mg/dL on postoperative days 7, 30, and 90, respectively. During the pandemic, 9 living donor liver transplants (1 adult, 8 pediatric) were performed with an average length of hospital stay of 17.1 days. Mean serum total bilirubin levels were 0.9, 0.5, and 0.4 mg/dL on postoperative days 7, 30, and 90, respectively. Mean serum aspartate aminotransferase levels were 38.1, 28.3, and 22.3 U/L on postoperative days 7, 30, and 90, respectively. All recipients and donors were successfully discharged. Only 1 liver recipient died (on day 55 after discharge as a result of oxalosis-induced heart failure). CONCLUSIONS: According to our results, when precautions are taken, transplant does not pose a risk to patients during the pandemic period. We attribute the safety and success shown to our newly developed protocol in response to the COVID-19 pandemic.

Quality of Life Through Gender Role Perspective in Candidate Renal Transplant Recipients: A Report From Baskent University Using the Short Form 36 Health Survey.

OBJECTIVES: The aim of the study was to evaluate the quality of life of patients with end-stage renal disease through a "gender role perspective." Patients were on hemodialysis treatment and on a wait list for transplant. MATERIALS AND METHODS: This study was conducted at the Baskent University Adana, Ankara, and Istanbul hemodialysis centers. Patients completed Short Form 36 Health Survey questionnaires voluntarily to evaluate quality of life. The questions were answered independently by patients while they were undergoing hemodialysis treatment. RESULTS: The mean age of participants was 54 ± 16.5 years. Quality of life was found to be higher in men (44.7 ± 19.2), and there was a negative correlation between quality of life and age in both sexes, as well as marriage age, number of pregnancies, and age of patient at the first live birth in women (P < .05). We found statistically significant differences between men and women regarding physical health and mental health dimensions. Quality of life scores increased with level of education (P < .001). In addition, patients in Ankara had the highest quality of life compared with Istanbul and Adana (P < .01). Average time on hemodialysis treatment, the number of weekly hemodialysis sessions, mean time of the disease, and mean duration of abandoning hemodialysis sessions were negatively associated with all components of quality of life (P < .05). CONCLUSIONS: We found that sex, education level, social status, and home city of patients had a high impact on quality of life. Thus, it is essential to educate both male and female patients regarding sex/gender and health issues before transplant to increase the recipient's physical and mental health dimensions.

Influence of Social, Economic, Familial, Marital Status, and Disease Adaptation on the Physical and Mental Health Dimensions of Patients Who Are Candidates for Renal Transplant.

OBJECTIVES: End-stage renal disease is a disease with a long duration, requiring patients to live with the limitations imposed by their condition. Stressors associated with this disease are demanding, with patients dependent on support from their social environment. Here, we aimed to show the influences of familial, social, economic, and marital status on quality of life in patients with end-stage renal disease. MATERIALS AND METHODS: Patients (190 women/188 men) who were under hemodialysis treatment and on transplant wait lists were included in the study. To evaluate the quality of life, patients completed the Short Form 36 health survey questionnaire voluntarily while undergoing hemodialysis treatment. All Short Form 36 questionnaire components were analyzed separately, and all social, economic, and business life dimensions were examined with another questionnaire. RESULTS: Significant differences were observed between single and married patients regarding physical and mental health dimensions (P < .001), with quality of life higher in single patients than in married. Patients who lived in villages had lower health quality than patients who resided in cities or towns (P < .01). Patients who were home owners and who had a job had higher degrees of health quality than those who did not (P < .01). The lowest Short Form 36 scores were in housewives and farmers (P < .001). Comparisons between patients who went home after hemodialysis versus those who went to work showed better Short Form 36 scores in working patients (P < .001). Patients with private insurance and family support had better Short Form 36 scores (P < .001). Patients who did not comply with their doctor and dietician showed the lowest health quality (P < .05). Regular or irregular drug use did not affect scores. CONCLUSIONS: Familial, social, economic, and marital statuses, in addition to the influence of disease adaptation, independently affected the well-being of patients with end-stage renal disease.
