Heart failure (HF) is a major cause of significant morbidity, mortality, and hospitalization worldwide including the Philippines. Congenitally corrected transposition of the great arteries (C-TGA) occurs when the right atrium enters the morphological left ventricle which gives rise to the pulmonary artery and the left atrium communicates with the right ventricle which gives rise to the aorta. Heart failure can occur in C-TGA especially if associated with other heart defects. Ideal management is anatomic correction via surgery to prevent or address heart failure. Peritoneal dialysis has been used as a therapeutic intervention for patients with refractory heart failure and kidney injury with or without kidney failure due to its gentler fluid removal compared to conventional ultrafiltration resulting in less myocardial stunning and neurohormonal activation. We present the case of a patient with heart failure who started on peritoneal dialysis (PD) as an adjunct therapy for fluid management after failing to satisfactorily achieve volume control with diuretics. The patient is a 56-year-old man with C-TGA admitted for decompensated heart failure. He was initially treated with intravenous diuretics on the first admission but was readmitted after 3 months for decompensation this time with borderline low blood pressure making diuresis difficult. The patient was given loop diuretics, tolvaptan, and angiotensin receptor neprilysin inhibitor (ARNI) but still with decreasing trends in urine output and inadequate symptom control. PD was initiated before discharge with subsequent improvement in heart failure symptoms. The patient was on regular follow-up for PD maintenance and titration of heart failure medication. In this case report, we have shown how PD can be an effective adjunct to guideline-directed medical therapy in patients with severely symptomatic heart failure who have an unstable hemodynamic status and for which volume management cannot be satisfactorily achieved with diuretics.

The potential mechanism by which sodium-glucose cotransporter 2 (SGLT2) inhibitors prevent cardiovascular disease (CVD) is being widely investigated. Improved insulin resistance, along with decreased body fat mass associated with SGLT2 inhibitor treatment is consistent with previously well-established factors contributing to the prevention of CVD. These factors are responsible for reduction of oxidative stress as well as improvement of systemic inflammation. Because heart failure was one of the most dramatically improved cardiovascular events in various clinical trials and because SGLT2 inhibitors promote osmotic diuresis and natriuresis, hemodynamic changes are considered as a critical mechanism responsible for the cardioprotective effect of SGLT2 inhibitors. Restored tubuloglomerular feedback by SGLT2 inhibitors might play a role in renoprotection, which in turn, leads to fewer CVDs. Finally, blood ketone body increments in response to SGLT2 inhibition might act as a “super-fuel” for salvaging the failing diabetic heart.

PURPOSE: This is a descriptive study conducted in order to survey sleep patterns and factors responsible for sleep disturbance among adolescent cancer patients after hospital admission. METHODS: The study group included 46 adolescent cancer patients aged 10 to 19 who received admission care in multi-bed hospital rooms from March to June 2016. Data on patterns and quality of sleep, and factors causing sleep disturbance were recorded using the Verran and Snyder-Halpern (VSH) Sleep Scale, the Pittsburgh Sleep Quality Index (PSQI), and a sleep disturbance questionnaire. RESULTS: There was no difference in patterns and quality of sleep prior to and after hospital admission in the study group. However, patients experienced sleep disturbance, as defined by PSQI > 5, both before (5.43) and after (6.30) admission. The most important physical, emotional and environmental factors causing sleep disturbance after admission were nocturnal diuresis, monotony of admission care, and crying of younger patients respectively. CONCLUSION: This study focused on sleep patterns and factors causing sleep disturbance after hospital admission for adolescent cancer patients. Future studies should aim to develop nursing interventions resulting in an environment that improves sleep quality. Additional studies should focus on developing daytime programs to determine the impact of admission care on other quality of life parameters.

Ureteral jets are the result of a forceful ejection of urine from the vesicoureteral junction into the urinary bladder. By using color Doppler ultrasonography (US), we aimed to identify distinct ureteral jets in dogs, provide insight into ureteral obstruction, and facilitate study of urodynamics and vesicoureteric sphincter function via pulsed Doppler US. Color Doppler US was applied to detect urinary flow from the right ureteral orifices in eight healthy beagles. Under anesthesia, 0.9% saline (2.5 mL/kg/h) and furosemide (0.5 mg/kg) were administered intravenously to assist in detection of distinct ureteral jets and examine their frequency, velocity, duration, and waveform. In all dogs, ureteral jets were visualized under diuresis and anesthesia within 2 to 5 min (mean 3.57 ± 0.90 min) of the furosemide injection. Mean frequency, peak velocity, and duration of right ureteral jets in seven dogs in whom six ureteral jet waveform patterns were identified were 9.86 ± 3.09 jets/min, 34.07 ± 10.02 cm/sec, and 2.82 ± 1.08 sec, respectively. During the 10 min period starting 10 min after the initial jet appeared, only three waveforms were identified. Color Doppler US of ureteral jets may aid in assessing vesicoureteric sphincter function and ureteral abnormalities, such as ureteral obstruction, in dogs.

Amyotrophic lateral sclerosis (ALS) patients rarely present with either syndrome of inappropriate antidiuretic hormone secretion or generalized edema. Tolvaptan is a selective vasopressin V2 receptor antagonist that produces effective aquaresis, and its use in ALS patients has not been previously reported. A 50-year-old male ALS patient was admitted because of both generalized edema and dilutional hyponatremia. These manifestations were refractory to conventional diuretics and fluid therapy, but a very brisk diuresis was induced by tolvaptan administration. Edema and hyponatremia were also improved, and the patient was able to be discharged without tolvaptan. In this case report, we postulate how edema and dilutional hyponatremia developed in the patient, and discuss the mechanism of tolvaptan in treating hypervolemic hyponatremia. Further experience is necessary to evaluate the usefulness of tolvaptan in patients with neurological disorders.

Rhabdomyolysis results from acute damage to skeletal muscles caused by various conditions, of which hypokalemia is a recognized but rare example. Although primary aldosteronism may cause severe hypokalemia leading to rhabdomyolysis, the potassium level of such patients can be within the normal range. Hypokalemia is most frequently triggered when these patients are exposed to an additional insult, such as diuretic stress. Similarly, overzealous consumption of ionic beverages with osmotic diuretic effects can cause hypokalemia. Here, we describe a patient with an aldosterone-secreting adrenal adenoma, who presented with acute rhabdomyolysis secondary to severe hypokalemia triggered by consumption of a large volume of ionic beverage for 3 weeks.

The safety and effectiveness of a novel Chinese one-shot dilation technique based on stimulated diuresis for percutaneous nephrolithotomy (PCNL) were investigated. After the feasibility of the Chinese one-shot dilation based on stimulated diuresis was verified by an animal study, this technique was applied in the clinical practice. A total of 67 patients in our department underwent the modified PCNL from July 2014 to June 2015. After the renal infundibulum was distended by stimulated diuresis, the kidney was punctured under the ultrasonographic guidance via the fornix of the target calyx. The working channel was dilated using a special designed pencil-shaped fascial dilator. The successful access rate, nephrostomy tract creation time, pre- and postoperative hemoglobin values and serum creatinine concentrations, stone-free rate and complications were recorded and analyzed. The renal infundibulum was successfully distended in all of the patients by the diuresis treatment. Under the ultrasonographic guidance, the successful access rate was 100% and the mean tract creation time was 2.0 min (range: 1.5-5.0 min). The stone-free rate right after surgery was 91.0%. Although the postoperative hemoglobin was significantly reduced (P<0.01), transfusion was not clinically necessary. There was no significant difference in serum creatinine concentrations before and after operation (P>0.05). No severe complication occurred during or after the PCNL. It was suggested that this Chinese one-shot dilation technique based on stimulated diuresis is an efficient and safe innovation for PCNL, and is even helpful for those patients with non-dilated pelvicaliceal systems.

Familial renal glycosuria (FRG) is an inherited disorder characterized by persistent glycosuria in the absence of hyperglycemia. It is caused by mutations in the sodium-glucose co-transporter, leading to increase in the renal excretion of glucose and sodium. However, there have been no studies on the role of fasting and postprandial changes in the urinary sodium excretion in patients with FRG. We report a case of renal glycosuria, which was confirmed by a SLC5A2 mutation via gene sequencing, and compared the postprandial urinary glucose and sodium excretion. A 26-year-old man sometimes experienced glycosuria on routine screening; however, other laboratory findings were normal. His fasting and postprandial urinary glucose excretion levels were 295mg/dL and 2,170mg/dL, respectively. The fasting and postprandial urinary sodium excretion levels were 200mEq/L and 89mEq/L, respectively. In patients with FRG, excessive diuresis might be prevented by a compensatory mechanism that reduces postprandial sodium excretion.

Since 2008, the Food and Drug Administration has required cardiovascular (CV) safety trials for all anti-diabetic medications available in the USA. Thus, new agents like dipeptidyl peptidase 4 inhibitors and glucagon-like peptide-1 receptor agonists have been tested in CV safety trials. The results of the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME) were released last year. Of the sodium-glucose cotransporter 2 (SGLT2) inhibitors tested, empagliflozin demonstrated a CV benefit in this trial. Another study of the renal protective effects of empagliflozin was released this year. The mechanisms supporting the cardio- and reno-protective effects of empagliflozin remain controversial. Hemodynamic changes related to SGLT2 inhibitors via natriuresis and osmotic diuresis are one potential mechanism. The Canadian Diabetes Association and European Society of Cardiology recently suggested SGLT2 inhibitors as an optimal anti-diabetic medication for patients with type 2 diabetes with overt CV disease. Further studies elucidating the potential mechanisms of cardio- and reno-protective effects of SGLT2 are needed.

To investigate the urination-reducing effect and mechanism of Zhuangyao Jianshen Wan (ZYJCW). In this study, SI rats were subcutaneously injected with 150 mg · kg(-1) dose of D-galactose to prepare the sub-acute aging model and randomly divided into the model group, the Suoquan Wan group (1.17 g · kg(-1) · d(-1)), and ZYJCW high, medium and low dose groups (2.39, 1.20, 0.60 g · kg(-1) · d(-1)) , with normal rats in the blank group. They were continuously administered with drugs for eight weeks. The metabolic cage method was adopted to measure the 24 h urine volume and 5 h water load urine volume in rats. The automatic biochemistry analyzer was adopted to detect urine concentrations of Na+, Cl-, K+. The ELISA method was used to determine serum aldosterone (ALD) and antidiuretic hormone (ADH). The changes in P2X1 and P2X3 mRNA expressions in bladder tissues of rats were detected by RT-PCR. According to the results, both ZYJCW high and medium dose groups showed significant down-regulations in 24 h urine volume and 5 h water load urine volume in (P <0.05, P <0.01), declines in Na+ and Cl- concentrations in urine (P <0.01), notable rises in plasma ALD and ADH contents (P <0.05, P <0.01) and remarkable down-regulations in the P2X1 and P2X3 mRNA expressions in bladder tissues (P <0.01). The ZYJCW low dose group revealed obvious reductions in Na+ and Cl- concentrations in urine (P <0.01). The results indicated that ZYJCW may show the urination-reducing effect by down-regulating the P2X1 and P2X3 mRNA expressions in bladder tissues of rats with diuresis caused by kidney deficiency.
