Does family support mediate the effect of anxiety and depression on maternal-fetal attachment in high-risk pregnant women admitted to the maternal-fetal intensive care unit?

Purpose@#This study investigated the mediating effect of family support in the relationships of anxiety and depression with maternal-fetal attachment among pregnant women admitted to the maternal-fetal intensive care unit (MFICU) in Korea. @*Methods@#The participants were high-risk pregnant women with a gestational age of at least 20 weeks who were admitted to MFICUs in Busan and Yangsan. The Korean versions of four measurement tools were used for the self-report questionnaire: Spielberger’s State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, Cobb’s family support measurement, and Cranley’s maternal-fetal attachment scale. Data were collected from June 22 to September 20, 2020. Out of 124 participants, data from 123 respondents were analyzed. Descriptive statistics and regression analysis were done. @*Results@#The average age of participants was 34.1 years. Their anxiety level was medium (43.57±11.65 points out of 80) and 53.6% were identified as having moderate depression (average 10.13±5.48 points out of 30). Family support was somewhat high (average 43.30±5.03 points out of 55). The average score of maternal-fetal attachment was also somewhat high (73.37±12.14 points out of 96). Family support had a partial mediating effect in the relationships of anxiety and depression with maternal-fetal attachment among high-risk pregnant women admitted to the MFICU. @*Conclusion@#Maintaining family support is challenging due to the nature of the MFICU. Considering the mediating effect of family support, establishing an intervention plan to strengthen family support can be helpful as a way to improve maternal-fetal attachment for high-risk pregnant women admitted to the MFICU.

Comparison of outcomes according to urine chemistry testing time for the causes of acute kidney injury patients admitted to the emergency room

Objective@#The rapid identification and treatment of an acute kidney injury (AKI) can help to restore the kidney function. To differentiate between pre-renal AKI and intrinsic AKI, a urine chemistry test was performed to determine the function of the renal tubules. On the other hand, there is no report showing that it is helpful to arrive at the hospital as early as possible and to perform these urine chemistry tests as soon as possible. @*Methods@#This study analyzed the timing of urinary chemistry tests in AKI patients who were admitted to the author’s hospital through the emergency departments (ED) in the last three years and divided into two groups. The early group was defined as patients who performed the test within three hours of arrival in the ED. The late group was defined as patients who were late or not. The prognostic factors were the change in 30-day estimated glomerular filtration rate (eGFR) and duration of hospital stay. @*Results@#The changes of eGFR after 30 days in each group were 41.6±27.57 mL/min/1.73 m2 (early group, n=92) vs. 30.39±26.37 mL/min/1.73 m2 (late group, n=180) (P=0.001). Early group patients were discharged more quickly than patients in the late group (hospital day, 11.49±10.14 vs. 13.84±10.53; P=0.041). @*Conclusion@#A urine chemistry test is a test to help determine the cause of AKI. Based on the results of urine chemistry performed within three hours after arrival at the hospital, patients with AKI who visited the emergency room had betterimproved kidney function and less hospitalization time than the patients who were late or untested at the time of treatment.

HELLP syndrome in a pregnant patient with Gitelman syndrome

Gitelman syndrome is characterized by hypokalemia, metabolic alkalosis, hypocalciuria, and hypomagnesemia. The clinical course of Gitelman syndrome in pregnant women remains unclear, but it is thought to be benign. We report here the first Korean case of atypical eclampsia in a 31-year-old who was diagnosed with Gitelman syndrome incidentally during an antenatal screening test. The patient did well during pregnancy despite significant hypokalemia. At 33 weeks’ gestation, the patient exhibited eclampsia, hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, and renal insufficiency without significant hypertension or proteinuria. We explain this unusual clinical course through a review of the relevant literature.

Chronic hepatitis C healed by peginterferon-α and rivabirin treatment after kidney transplantation / 영남의대학술지

Hepatitis C virus (HCV) infection is present in a high proportion of patients with kidney transplantation. Compared with uninfected kidney transplant recipients, HCV infected kidney recipient have higher prevalence of liver disease and worse allograft survival after transplantation. Interferon monotherapy before transplantation is standard therapy for HCV-infected kidney transplant candidates. If HCV infection is discovered after transplantation, interferon monotherapy is considered due to the limited critical situation. However, in this patient, who was a kidney recipient, HCV infection was treated after kidney transplantation with peginterferon-α and rivabirin. As a result, the patient achieved sustained virologic response.

Successful Treatment of Prostatic Abscess Accompanied by Methicillin-Resistant Staphylococcus aureus Bacteremia Using a Percutaneous Fine-Needle Aspiration under the Computed Tomography Guidance / 이화의대지

Prostatic abscess is not a common entity which is characterized by non-specific clinical presentations. This poses a diagnostic challenge for clinicians. Clinicians routinely consider antibiotic treatments concomitantly with drainage for the treatment of prostatic abscess. But there are no established guidelines for its optimal timing, methods and indications. Surgical drainage procedures include transurethral resection of the prostate and perineal incision and drainage. But there is variability in the prognosis of patients between the procedures. We have treated a 48-year-old diabetes patient with prostatic abscess accompanied by MRSA bacteremia using a percutaneous fine-needle aspiration under the computed tomography (CT) guidance. The patient achieved improvement of the symptoms and in follow up CT findings. A percutaneous drainage under the CT guidance is advantageous in that it causes fewer complications. However, Further studies are warranted to establish the optimal timing, methods and indications in patients with prostate abscess.

Comparison of the Clinical Outcomes between Anti-thymocyte Globulin and Basiliximab Induction Therapy in Deceased Donor Kidney Transplantation: Single Center Experience / 대한이식학회지

BACKGROUND: The aim of this study is to evaluate the clinical outcomes between anti-thymocyte globulin (ATG) and basiliximab induction in deceased donor kidney transplantation (DDKT). METHODS: Between May 2006 and February 2015, 40 patients underwent DDKT at our institution. Three cases (7.5%) of them were lost during the following-up schedule. In this study, ATG induction criteria were donor age >50 years old or donor creatinine level >1.3 mg/dL except hepatitis B virus positive and hepatitis C virus positive recipients. Recipients were divided into two groups: the ATG group (n=20) and the basiliximab group (n=17). RESULTS: The 1-year patient survival in the ATG group was 89.4% compared to 93.8% in the basiliximab group (P=0.989). Graft survival for a 1 year in the ATG and the basiliximab group was 89.1% and 93.8%, respectively (P=0.967). Incidences of acute rejection episodes were more prevalent in the basiliximab group (15.0% vs. 29.4%, P=0.428). The glomerular filtration rate level by period of recipients was not different in both group (12th month, 64.60+/-16.17 mg/dL vs. 68.51+/-18.60 mg/dL, P=0.544). The overall complications during the follow-up were not significantly different in both groups (90.0% vs. 76.5%, P=0.383). CONCLUSIONS: The results showed that there was no difference in the patient survival and graft survival between induction of ATG and basiliximab of the DDKT were not different. Therefore, use of both induction agents led to a good patient and graft survival and ATG might be a safe and preferable agent for relatively poor renal function of donor in kidney transplantation.

Improvement of Hypoxemia by Inhaled Nitric Oxide Gas Therapy in Potential Deceased Donor / 대한이식학회지

Potential diseased donors manifest altered physiological changes associated with pulmonary edema, profound hemodynamic and metabolic abnormalities. These derangements may be more significant after apnea tests which result in severe hypoxemia and cardiovascular complications. Nitric oxide (NO) inhalation therapy can be applied following apnea tests in the brain-dead donor whose ventilator support has been maintained with high positive end-expiratory pressure. Inhalation of NO gas causes selective dilation of blood vessels in only those lung segments that are actively participating in gas exchange (oxygen and carbon dioxide) at the alveolar capillary level. In other words, this increases the blood flow to areas of the lung where oxygen is being provided and thus improves oxygen levels in the body. We report on the case of a 14-year-old organ donor with inhaled NO therapy after apnea testing. The duration of NO inhalation therapy was 14 hours. This deceased donor, who suffered with severe hypoxemia and hemodynamic instability after apnea tests, improved after NO gas therapy and adequate vasoactive drugs. NO gas therapy will be helpful for improving oxygen delivery to pulmonary vessels. Two kidneys and one liver were successfully retrieved from donors. These recipients had well preserved function of allografts. Therefore, NO inhalation can be helpful in improvement of hypoxemia and increasing organ availability in deceased organ donors.

Renal Infarction after NSAID Treatment / 대한내과학회지

Nonsteroidal anti-inflammatory drugs (NSAIDs) are popular in general practice. Their adverse renal effects have been well documented. Common NSAID-related renal side effects range from dysfunctional renal hemodynamic responses, nephrotic syndrome, electrolyte disturbances, acute interstitial nephritis, chronic interstitial nephritis with papillary necrosis, and acute flank pain syndrome to acute renal failure. Decreased prostaglandin synthesis can lead to renal ischemia and hemodynamically related acute renal failure. Cases of acute renal failure syndrome accompanied by severe loin pain after anaerobic exercise (ALPE) or binge drinking have previously been reported in individuals taking NSAIDs. However, severe flank pain after high-dose NSAID treatment in the absence of other conditions (exercise or volume contraction) is rare. We report a case of a 51-year-old man who suffered from severe pain in both flanks after NSAID treatment. Computed tomography revealed hypodense lesions in both kidneys.

Impact of gene polymorphisms of interleukin-18, transforming growth factor-beta, and vascular endothelial growth factor on development of IgA nephropathy and thin glomerular basement membrane disease

BACKGROUND: We investigated the effects of gene polymorphisms on the development of IgA nephropathy and thin glomerular basement membrane (GBM) disease by analyzing polymorphisms in the interleukin (IL)-18, transforming growth factor (TGF)-beta, and vascular endothelial growth factor (VEGF) genes in Korean patients. METHODS: This study included 146 normal individuals and 69 biopsy-proven IgA nephropathy and 44 thin GBM disease patients. The gene polymorphisms -607A/C and -137G/C in IL-18, -509C/T and T869C in TGF-beta, and -2578C/A and 405C/G in VEGF were investigated in DNA extracted from peripheral blood. RESULTS: The frequencies of the IL-18 -607CC genotype (43.5% vs. 21.2%, P=0.002, P corrected=0.012) and the VEGF 405GG genotype (37.7% vs. 21.2%, P=0.002, P corrected=0.012) were significantly increased in the IgA nephropathy group compared with the control group, whereas no significant differences in genotype frequency were observed between the thin GBM disease and control groups. However, there were no significant differences in genotype and allele frequencies between the IgA nephropathy and thin GBM disease groups. CONCLUSION: This study did not show any statistically significant differences of six selected gene polymorphisms of the IL-18, TGF-beta, and VEGF genes between IgA nephropathy and thin GBM disease. Additional extensive studies are required to clarify the potential role of gene polymorphism to discriminate IgA nephropathy and thin GBM disease without renal biopsy.

A Case of Transient Central Diabetes Insipidus after Aorto-Coronary Bypass Operation

Diabetes insipidus (DI) is characterized by excessive urination and thirst. This disease results from inadequate output of antidiuretic hormone (ADH) from the pituitary gland or the absence of the normal response to ADH in the kidney. We present a case of transient central DI in a patient who underwent a cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). A 44-yr-old male underwent a CABG operation. An hour after the operation, the patient developed polyuria and was diagnosed with central DI. The patient responded to desmopressin and completely recovered five days after surgery. It is probable that transient cerebral ischemia resulted in the dysfunction of osmotic receptors in the hypothalamus or hypothalamus-pituitary axis during CPB. It is also possible that cardiac standstill altered the left atrial non-osmotic receptor function and suppressed ADH release. Therefore, we suggest that central DI is a possible cause of polyuria after CPB.

A Case of a False-Positive Anti-Myeloperoxidase Antibody ELISA in a Patient with Hypothyroidism / 전남의대학술지

We present a case of a false-positive anti-myeloperoxidase (MPO) antibody result on an ELISA in a patient with anti-thyroid microsomal antibody (TMA)-positive hypothyroidism. A 41-year-old woman presented with dyspnea on exertion. The initial evaluation revealed pericardial effusion associated with hypothyroidism. In addition, microscopic hematuria with normal renal function and positive cytoplasmic anti-neutrophil cytoplasmic antibodies (c-ANCA) on immunofluorescent assay were found. In further evaluation, elevated anti-TMA and MPO antibodies by ELISA. While no definite signs of vasculitis were present, the clinical state improved with thyroid hormone replacement and diuretics. Anti-MPO antibody was still positive in the follow-up tests, and microscopic hematuria persisted. On the basis of previous reports that thyroid peroxidase and MPO molecules contain cross-reactive epitopes that are exposed in denaturated molecules, we suggest that in a patient with anti-TMA-positive hypothyroidism, anti-MPO antibody might also be positive on ELISA without clinical signs of vasculitis.

A Case of Bilateral Acute Renal Cortical Necrosis Complicated by Tranexamic Acid Administration / 대한내과학회지

Acute renal cortical necrosis is an anuric form of acute renal failure. We experienced a case of renal cortical necrosis complicated by tranexamic acid administration. To our knowledge, only three cases of renal cortical necrosis have been reported worldwide. A 49-year-old man was referred with hemothorax and multiple bone fractures following a traffic accident. Tranexamic acid, and hemocoagulase were injected three times a day. After the 4th dose of hemostatics, anuria developed abruptly, the platelet count decreased to 84,000 /microL, and the serum creatinine was increased to 2.56 from 1.06 mg/dL. On the 4th Intensive Care Unit (ICU) day, computed tomography (CT) showed bilateral renal cortical necrosis with normal renal arteries and aorta. The oliguria persisted for 14 days and temporary hemodialysis was performed. The serum creatinine had decreased to 2.12 mg/dL 8 months after discharge.

Outcome of Cadaveric Kidney Transplantation from Expanded Criteria Donors / 대한내과학회지

BACKGROUND/AIMS: The Korean Network for Organ Sharing (KONOS) was established in 2000, and the KONOS criteria for expanded-criteria donors (ECD) have since been applied to kidney allocation from deceased donors. The outcome of cadaveric kidney transplantation from ECD according to KONOS criteria has not been investigated. METHODS: Seventy-seven cadaveric kidney transplants from January 2003 to December 2009 were recruited retrospectively. Factors that influence the glomerular filtration rate (GFR) of graft kidneys up to 36 months after transplantation were evaluated. Postoperative renal function and allograft and patient survival in the ECD group (n = 28) were compared with those in the standard-criteria donor (SCD) group (n = 49). RESULTS: The GFR of graft kidneys was different according to donor GFR, age, hypertension history, and cause of brain death. In the ECD group, GFR was lower than that in the SCD group by KONOS criteria. No differences in allograft or patient survival were observed until 3 years after kidney transplantation. CONCLUSIONS: Cadaveric kidney transplantation using the ECD by KONOS criteria is acceptable in term of graft and 3-year patient survival, although the GFR was lower in the ECD than in the SCD group.

A Case of Primary Hyperoxaluria with Renal Allograft Dysfunction / 대한신장학회지

Primary hyperoxaluria is a rare disorder of glyoxylate metabolism in which hepatic enzyme deficiencies result in overproduction of oxalate. The resulting elevation of urinary oxalate excretion leads to recurrent urolithiasis and progressive nephrocalcinosis. End-stage renal disease frequently occurs and is accompanied by systemic oxalate deposition along with its harmful effects. With the rarity and various clinical heterogeneity of the disease, the high proportion of patients in whom diagnosis is made after advanced renal failure have developed it. On account of its high rate of graft loss associated with primary hyperoxaluria, isolated kidney transplantation has been replaced by combined liver/kidney transplantation. In this report, we describe a case of primary hyperoxaluria with kidney graft failure who had a history of recurrent renal stones.

Detecting Bacterial Growth in Continuous Ambulatory Peritoneal Dialysis Effluent Using Two Culture Methods

BACKGROUND/AIMS: The aim of this study was to evaluate the peritonitis-causing bacteria detected in peritoneal fluid using a blood culture bottle in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). METHODS: One-hundred and eleven dialysates from 43 patients suspected of peritonitis related to CAPD were retrospectively evaluated between May 2000 and February 2008. In all cases, 5 to 10 mL of dialysate was inoculated into a pair of BacT/Alert blood culture bottles, and 50 mL of centrifuged dialysate was simultaneously inoculated into a solid culture media for conventional culture. The results were compared to those of the conventional culture method. Isolated microorganisms were compared between the two methods. RESULTS: The blood culture method was positive in 78.6% (88 / 112) of dialysate specimens and the conventional culture method in 50% (56 / 112, p < 0.001). CONCLUSIONS: The blood culture method using the BacT/Alert system is useful for culturing dialysates and improves the positive culture rate in patients with suspected peritonitis compared to the conventional culture method.

Candida zeylanoides Peritonitis in a Continuous Ambulatory Peritoneal Dialysis Patient / 대한신장학회지

Despite the frequent occurrence of peritonitis in patients with continuous ambulatory peritoneal dialysis (CAPD), fungal peritonitis is uncommon and usually associated with antibiotics and immunodeficiency. Most of the fungal isolates are usually Candida albicans, Candida parapsilosis, Candida guilliermondii or Candida torulopsis. The authors report a case of fungal CAPD related peritonitis due to Candida zeylanoides that occurred in a patient with the absence of the usual risk factors for fungal peritonitis. Treatment with intravenous fluconazole was successful.
