Appropriate control of diet and water intake is important for maintaining normal blood pressure, fluid and electrolyte homeostasis in the body. It is relatively understood that the amount of sodium and potassium intake directly affects blood pressure and regulates ion transporters; Na and K channel functions in the kidney. However, little is known about whether diet and water intake regulates Aquaporin (AQP) function. AQPs, a family of aquaporin proteins with different types being expressed in different tissues, are important for water absorption by the cell. Water reabsorption is a passive process driven by osmotic gradient and water permeability is critical for this process. In most of the nephron, however, water reabsorption is unregulated and coupled to solute reabsorption, such as AQP1 mediated water absorption in the proximal tubule. AQP2 is the only water channel founded so far that can be regulated by hormones in the kidney. AQP2 expressed in the apical membrane of the principal cells in the collecting tubule can be regulated by vasopressin (antidiuretic hormone) controlling the final volume of urine excretion. When vasopressin binds to its receptor on the collecting duct cells, it stimulates the translocation of AQP2 to the membrane, leading to increased water absorption via this AQP2 water channel. However, some studies also indicated that the AQP2 is also been regulated by vasopressin independent mechanism. This review is focused on the regulation of AQP2 by diet and the amount of water intake on salt and water homeostasis.

OBJECTIVE: In Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), a new specifier of major depressive disorder (MDD) "with anxious distress" allows characterization of additional symptoms. The aim of this study was to investigate difference in treatment outcome of MDD with versus without anxious distress specifier in DSM-5. METHODS: Retrospective chart review of patients admitted to a university hospital with a primary diagnosis of MDD in a period from March 2013 to September 2014 was conducted. We reviewed anxious distress symptoms, medications and detailed clinical information at index episode. We compared treatment outcomes of anxious distress group with those of non anxious distress group. RESULTS: There were differences in remission rate after 4 weeks later (18.5% vs. 44.4%, p=0.040) and at discharge (33.3% vs. 66.7%, p=0.014) between anxious distress and non anxious distress. However, no significant differences were observed in the sociodemographic characteristics, treatment regimens, and response rate. CONCLUSION: Anxious distress specifier might be worthwhile to be further evaluated as a diagnostic entity of its own requiring specific diagnosis and therapeutic attention.

Rhabdomyolysis is a common clinical and laboratory syndrome resulting from reversible skeletal muscle injury, with release of muscle cell contents into the plasma. Cardioversion, and cardiopulmonary resuscitation may produce rhabdomyolysis and myoglobinuria. We report a 5-year-old boy surviving after cardiopulmonary resuscitation and repeated 5 times of cardioversion. He showed elevated serum BUN and creatinine levels, requiring hemodialysis treatment. We had tried 5 times of intermittent hemodialysis, but oliguria was continued and there was no change of serum BUN and creatinine. His urine output was less than 100 cc per day and he showed severe edema and weight gain of 7 kg, and so we started the continuous renal replacement therapy (Prismaflex(R), gambro). After 12 days of continuous venovenous hemodiafiltration (CVVHDF), his urine output recovered and his BUN, creatinine, liver enzyme, creatine kinase, and lactate dehydrogenase levels returned to normal. During the treatment of CVVHDF, he had shown persistent hypercalcemia, and so we changed dialysate and replacement solution from hemosol B0 to calcium free solution. The hypercalcemia was controlled successfully using this calcium free pharmacy-made bicarbonate solution.

OBJECTIVE: We compared the one-year rehospitalization rates of first-episode bipolar manic patients who were discharged while being treated with atypical antipsychotics in combination with mood stabilizers. METHODS: We monitored the rehospitalization status of the first-episode bipolar manic patients who were discharged between 1 January 2003 and 31 December 2008 while they were taking risperidone (n=34), olanzapine (n=26) or quetiapine (n=32) in combination with mood stabilizers. Rehospitalizations were tracked over a 1-year period using the Kaplan-Meier method and Cox regression model was used to analyze covariates thought to affect time to rehospitalization. RESULTS: The rehospitalization rates during the 1-year follow-up period for patients taking atypical antipsychotics plus mood stabilizers were 22.8% (n=21). There were no significant differences in rehospitalization estimated using the Kaplan-Meier formula among the patients treated with risperidone (29.4%), olanzapine (23.1%) or quetiapine (15.6%). The psychotic symptoms, previous depressive episodes, lower Global Assessment of Functioning (GAF) score at discharge and less length of first hospitalization contributed to the risk of rehospitalization. CONCLUSION: The 1-year rehospitalization rates of first-episode bipolar manic patients taking risperidone, olanzapine, or quetiapine do not differ and the psychotic symptoms and previous depressive episodes affect time to rehospitalization.

It has been well established that women generally have lower incidence rates of hypertension than men at similar ages and these differences may vary with age. It also has been observed in many studies that after menopause, blood pressure (BP) increases in women to levels even higher than in men. The lack of estrogens may not be suggested as the only component involved in the development of postmenopausal hypertension. Thus, in this mini-review, the possible mechanisms by which sex hormones may influence the BP are discussed. This review also examines the renal regulatory mechanisms for gender differences in BP and explores the effects of salt intake on BP (salt-sensitivity) in pre and post-menopausal women. Estrogen has been shown to stimulate nitric oxide (NO) production, thus female sex hormones have a beneficial effect on BP control. Evidences that angiotensin type 2 receptor (AT2R) is up-regulated by estrogen support the favorable effects on BPs in women than men. The kidney plays an integral role in the regulation of arterial pressure through the mechanism of pressure-natriuresis, which has been shown to be modulated by the RAS. The prevalence of salt-sensitivity increases with age and low-salt diets has shown to help reduce systolic BP (SBP) and diastolic BP. While oral hormone replacement therapy has yielded only a neutral or minimal effect on the elevation of SBP, both the transdermal route replacement and a novel progestin with anti-aldosterone activity (drospirenone) has also shown to reduce SBP.

Major depressive disorder (MDD) is a recurrent, chronic, and devastating disorder leading to serious impairment in functional capacity as well as increasing public health care costs. In the previous decade, switching therapy and dose adjustment of ongoing antidepressants was the most frequently chosen subsequent treatment option for MDD. However, such recommendations were not based on firmly proven efficacy data from well-designed, placebo-controlled, randomized clinical trials (RCTs) but on practical grounds and clinical reasoning. Aripiprazole augmentation has been dramatically increasing in clinical practice owing to its unique action mechanisms as well as proven efficacy and safety from adequately powered and well-controlled RCTs. Despite the increased use of aripiprazole in depression, limited clinical information and knowledge interfere with proper and efficient use of aripiprazole augmentation for MDD. The objective of the present review was to enhance clinicians' current understanding of aripiprazole augmentation and how to optimize the use of this therapy in the treatment of MDD.

OBJECTIVE: C-reactive protein (CRP), lipoprotein (a)[Lp(a)], and fibrinogen are associated with systemic inflammatory reactions. Statins have anti-inflammatory effects. However, the effect of statins on these parameters is inconsistent. We evaluated the effect of statins on inflammatory markers and variables related to changes in these markers. METHODS: A total of 390 hypercholesterolemic patients were enrolled. Atorvastatin (n=112), lovastatin (n=25), pitavastatin (n=49), rosuvastatin (n=20), and simvastatin (n=184) were administered. Lipids, CRP, Lp(a), and fibrinogen levels were measured before and after 2 months of the therapy. RESULTS: Statins reduced cholesterol, low density lipoprotein (LDL) cholesterol, and triglyceride levels by -28.9+/-9.1% (P=0.000), -41.4+/-12.4% (P=0.000), and -11.6+/-39.4% (P=0.000), respectively and increased high density lipoprotein (HDL) cholesterol level by 2.56+/-13.2% (P=0.014). CRP levels decreased from 1.23+/-1.30 to 1.14+/-1.29 mg/L (P=0.000). Lp(a) levels were not changed (P=0.91) and fibrinogen levels increased from 277.8+/-54.4 to 282.6+/-56.9 mg/dL (P=0.042). Changes in CRP levels were associated with baseline CRP levels (r=-0.56, P=0.000) and changes in HDL cholesterol levels (r=-0.14, P=0.005). Changes in Lp(a) levels were associated with changes in triglyceride (r=-0.24, P=0.000) and baseline aspartate aminotransferase level (r=0.12, P=0.015). Changes in fibrinogen levels were associated with baseline fibrinogen levels (r=-0.40, P=0.000), sex (r=0.18, P=0.001), and changes in HDL cholesterol levels (r=-0.15, P=0.003). CONCLUSION: Inflammatory markers showed different responses to statins and changes in these markers were associated with different parameters. This finding suggests that anti-inflammatory effect of statin is confined to a specific pathway of inflammation.

PURPOSE: To investigate the role of alpha3 and alpha7 nicotinic acetylcholine receptor subunits (nAChRs) in the bladder, using a rat model with detrusor overactivity induced by partial bladder outlet obstruction (BOO). METHODS: Forty Sprague-Dawley rats were used: 10 were sham-operated (control group) and 30 were observed for 3 weeks after partial BOO. BOO-induced rats were further divided into 3 groups: Two groups of 10 rats each received intravesicular infusions with hexamethonium (HM group; n=10) or methyllycaconitine (MLC group; n=10), which are antagonists for alpha3 and alpha7 nAChRs, respectively. The remaining BOO-induced rats received only saline infusion (BOO group; n=10). Based on the contraction interval measurements using cystometrogram, the contraction pressure and nonvoiding bladder contractions were compared between the control and the three BOO-induced groups. Immunofluorescent staining and Western blotting were used to analyze alpha3 and alpha7 nAChRs levels. RESULTS: The contraction interval of the MLC group was higher than that of the BOO group (P<0.05). Nonvoiding bladder contraction almost disappeared in the HM and MLC groups. Contraction pressure increased in the BOO group (P<0.05) compared with the control group and decreased in the HM and MLC groups compared with the BOO group (P<0.05). Immunofluorescence staining showed that the alpha3 nAChR signals increased in the urothelium, and the alpha7 nAChR signals increased in the urothelium and detrusor muscle of the BOO group compared with the control group. Western blot analysis showed that both alpha3 and alpha7 nAChR levels increased in the BOO group (P<0.05). CONCLUSIONS: Alpha3 and alpha7 nAChRs are associated with detrusor overactivity induced by BOO. Furthermore, nAChR antagonists could help in clinically improving detrusor overactivity.
