Adverse effect profile of trichlormethiazide: a retrospective observational study
<p>Abstract</p> <p>Background</p> <p>Trichlormethiazide, a thiazide diuretic, was introduced in 1960 and remains one of the most frequently used diuretics for treating hypertension in Japan. While numerous clinical trials have indicated important side effects of thiazides, e.g., adverse effects on electrolytes and uric acid, very few data exist on serum electrolyte levels in patients with trichlormethiazide treatment. We performed a retrospective cohort study to assess the adverse effects of trichlormethiazide, focusing on serum electrolyte and uric acid levels.</p> <p>Methods</p> <p>We used data from the Clinical Data Warehouse of Nihon University School of Medicine obtained between Nov 1, 2004 and July 31, 2010, to identify cohorts of new trichlormethiazide users (n = 99 for 1 mg, n = 61 for 2 mg daily dosage) and an equal number of non-users (control). We used propensity-score matching to adjust for differences between users and control for each dosage, and compared serum chemical data including serum sodium, potassium, uric acid, creatinine and urea nitrogen. The mean exposure of trichlormethiazide of 1 mg and 2 mg users was 58 days and 64 days, respectively.</p> <p>Results</p> <p>The mean age was 66 years, and 55% of trichlormethiazide users of the 1 mg dose were female. In trichlormethiazide users of the 2 mg dose, the mean age was 68 years, and 43% of users were female. There were no statistically significant differences in all covariates (age, sex, comorbid diseases, past drugs, and current antihypertensive drugs) between trichlormethiazide users and controls for both doses. In trichlormethiazide users of the 2 mg dose, the reduction of serum potassium level and the elevation of serum uric acid level were significant compared with control, whereas changes of mean serum sodium, creatinine and urea nitrogen levels were not significant. In trichlormethiazide users of the 1 mg dose, all tests showed no statistically significant change from baseline to during the exposure period in comparison with control.</p> <p>Conclusions</p> <p>Our study showed adverse effects of decreased serum potassium and increased serum uric acid with trichlormethiazide treatment, and suggested that a lower dose of trichlormethiazide may minimize these adverse effects. These findings support the current trend in hypertension therapeutics to shift towards lower doses of thiazides.</p
Effect of candesartan monotherapy on lipid metabolism in patients with hypertension: a retrospective longitudinal survey using data from electronic medical records
<p>Abstract</p> <p>Background</p> <p>Studies focusing on the add-on effects of angiotensin II type 1 receptor blockers (ARBs) other than their antihypertensive effect are receiving attention. However, the effects of prolonged administration of ARBs on lipid metabolism in clinical cases are unclear. Our aims were to survey the changes in plasma lipid profile in patients with hypertension over a one-year period, and to examine the correlations between these values and the time after the start of ARB monotherapy with candesartan.</p> <p>Methods</p> <p>We carried out candesartan monotherapy in patients with mild to moderate hypertension and examined the longitudinal changes in plasma lipid profile. Data from 405 patients for triglyceride (TG), 440 for total cholesterol (TC), 313 for high density lipoprotein cholesterol (HDL-C) and 304 for low density lipoprotein cholesterol (LDL-C) were obtained from the electronic medical records (EMRs) in the Clinical Data Warehouse (CDW) of Nihon University School of Medicine (NUSM). The inverse probability of treatment weighting (IPTW) method (calculated from the inverse of the propensity score) was used to balance the covariates and reduce bias in each treatment duration. Linear mixed effects models were used to analyse the relationship between these longitudinal data of blood examinations and covariates of patient sex, age, diagnosis of diabetes mellitus (DM) and duration of candesartan monotherapy.</p> <p>Results</p> <p>Plasma HDL-C level was associated with sex, duration of treatment, and interaction of sex and treatment duration, but not with age or diagnosis of DM. HDL-C level was significantly decreased during the 6~9 months period (p = 0.0218) compared with baseline. TG and TC levels were associated with sex, but not with age, diagnosis of DM or treatment duration. LDL-C level was not associated with any covariate. Analysis of the subjects divided by sex revealed a decrease in HDL-C in female subjects (during the 6~9 months period: p = 0.0054), but not in male subjects.</p> <p>Conclusions</p> <p>Our study revealed that administration of candesartan slightly decreased HDL-C in female subjects. However, TG, TC and LDL-C levels were not influenced by candesartan monotherapy. Candesartan may be safely used for patients with hypertension with respect to lipid metabolism, because the effect of candesartan on lipids may be small.</p
An adaptive SC line equalizer for four-wire full-duplex and multirate digital transmission
金沢大学大学院自然科学研究科情報システム金沢大学工学部An adaptive switched-capacitor (SC) line equalizer system that can be applied to four-wire full-duplex and multirate digital transmission is described. Several kinds of noises can exist in programmable high-gain SC equalizers, such as switching noise, DC offset jump, and transient response. To avoid their effects, an adaptive SC filter is proposed. Two identical SC circuits are used in parallel. An input signal is fed into both SC circuits, and output signals from both circuits are alternately sent after the above noises are eliminated. Furthermore, many different data rates can be handled by slightly modifying an equalizer circuit. A bridged-tap echo canceller and a DC offset canceller are modified so as to be applied to the proposed adaptive SC filter. A line equalizer system, that handles data rates ranging from 3.2 to 64 kb/s was designed. An LSI was fabricated using a 3-μm CMOS process. Experimental results show that noise effects are mostly eliminated, and frequency responses and eye openings are close to the designed values
A single-chip SC line equalizer system for full duplex multi-bit rate digital transmission
The authors present a single-chip switched capacitor (SC) line equalizer system which can be applied to full duplex digital transmission. Adaptive SC filters, constructed with programmable capacitor arrays (PCAs), usually cause undesired responses, such as spike noise and transient response, which degrade data transmission quality. To avoid these phenomena, a duplex SC equalizer which has the same circuits in parallel is introduced. The PCAs in one duplex equalizer, whose output is not transferred, are varied. After the undesired phenomena vanish, the output is alternated. The equalizer system can be applied at several different bit rates by changing the external control signals. Algorithms and circuit realizations for a bridged tap echo canceller and a dc offset canceller are further improved

Pathway to psychiatric care in Japan: A multicenter observational study
<p>Abstract</p> <p>Background</p> <p>This study examines pathways to psychiatric care in Japan using the same method as the collaborative study carried out in 1991 under the auspices of the World Health Organization.</p> <p>Methods</p> <p>Thirteen psychiatric facilities in Japan were involved. Of the 228 patients who contacted psychiatric facilities with any psychiatric illness, eighty four visiting psychiatric facilities for the first time were enrolled. Pathways to psychiatric care, delays from the onset of illness to treatment prior to reaching psychiatrists were surveyed.</p> <p>Results</p> <p>Thirty three patients (39.4%) directly accessed mental health professionals, 32 patients (38.1%) reached them via general hospital, and 13 patients (15.5%) via private practitioners. The patients who consulted mental health professionals as their first carers took a longer time before consulting psychiatrists than the patients who consulted non-mental health professionals as their first carers. The patients who presented somatic symptoms as their main problem experienced longer delay from the onset of illness to psychiatric care than the patients who complained about depressive or anxiety symptoms. Prior to the visit to mental health professionals, patients were rarely informed about their diagnosis and did not receive appropriate treatments from their physicians. Private practitioners were more likely to prescribe psychotropics than physicians in general hospitals, but were less likely to inform their patients of their diagnosis.</p> <p>Conclusion</p> <p>This first pathway to psychiatric care study in Japan demonstrated that referral pathway in Japan heavily relies on medical resources. The study indicates possible fields and gives indications, underlining the importance of improving skills and knowledge that will facilitate the recognition of psychiatric disorders presenting with somatic and depressive symptoms in the general health care system and by private practitioners.</p
