Objective: Electroconvulsive therapy (ECT) has proven to be effective in treatment-resistant depression (TRD). In recent reports,70% to 90% of patients with TRD responded to ECT. However, post-ECT relapse is a significant problem. There are no studies investigating risk factors associated with reintroducing ECT in depressive patients after remission previously achieved with former ECT. The aim of the present study is to examine such risk factors using a sample of TRD patients. Methods: We conducted a chart review to examine patient outcomes and adverse events over short- and long-term periods. Forty-two patients met the criteria for major depressive disorder. Results: The response rate was 85.7% (36/42). There were no significant differences in the baseline characteristics of patients exhibiting remission, response or non-response. The rate of adverse events was 21.4% (9/42). Among 34 patients who were available for follow-up, 18 patients relapsed (relapse rate, 52.9%), and 6 patients were reintroduced to ECT. The patients’ age and age of onset were significantly higher in the re-ECT group than non re-ECT group. Conclusion: Our results suggest that older age and older age of onset might be considered for requirement of re-ECT after remission previously achieved with former ECT.

FCCP (carbonyl cyanide-4-(trifluoromethoxy)phenylhydrazone) is known to inhibit oxidative phosphorylation as a protonophore, dissipating the proton gradient across the inner mitochondrial membrane. To understand the toxicity of FCCP, 3-day, 2- and 4-week repeated oral dose studies were performed in male rats. In the 3-day and 2-week repeated dose toxicity studies, observations included salivation, increased body temperature, and dead and moribund animals. Increased liver weight was observed in conjunction with hydropic degeneration and centrilobular necrosis of hepatocytes. In addition, pathological changes were observed in the pancreas, testis, epididymal duct, stomach and parotid gland. Electron microscopic examination revealed mitochondrial pleomorphism in the hepatocytes. Swelling of mitochondria was observed in the alpha cells and beta cells of the pancreas. Dilatation of rough endoplasmic reticulum, Golgi bodies and loss of secretory granules were also noted in the beta cells of the pancreas. FCCP was also compared with three other mUncouplers (DNP, OPC-163493 and tolcapone) with regard to in vitro mitochondrial uncoupling (mUncoupling) activities. FCCP produced the peak ΔOCR (oxygen consumption rate) at the lowest concentration (0.4 μM), followed by OPC-163493, tolcapone, and DNP, based on peak values in ascending order of concentration (2.5, 10, and 50 μM, respectively). Considering the relationship between the mUncoupling activity and toxicity profile of the four mUncouplers, there is no parallel relationship between the in vitro mUncoupling activity and the degree of in vivo toxicity. These findings may contribute to the efficient development of new mitochondrial uncoupler candidates.

This paper proposes a sinusoidal chargingdischarging method of the lithium-ion batteries (LiBs) to reduce the capacitances of the dc-capacitors in the previously proposed smart charger (SC) for electric vehicles (EVs) in single-phase three-wire distribution feeders with power quality compensator. The dc-capacitor current in the three-leg pulse-width-modulated (PWM) rectifier is detected, and then added to the reference value for the output current of the bidirectional dc-dc converter that is used to charge or discharge the LiBs. The addition of the detected dc-capacitor current to the reference value of the bidirectional dc-dc converter achieves the sinusoidal chargingand discharging-operations of the LiBs in EVs. The sinusoidal charging- and discharging-operations sink the voltage ripples in the dc-capacitors of both the PWM rectifier and bidirectional dc-dc converter in the SC. This achieves the substantial reduced dc-capacitors in the SC. The simulation results demonstrate that balanced and sinusoidal source currents with a unity power factor can be achieved reducing the capacitances of dc-capacitors in the SC.

The purpose of the study was to determine the effect of cartilage degeneration at the patellofemoral joint on clinical outcomes after open wedge high tibial osteotomy and to investigate the predisposing factors for progressive patellofemoral cartilage degeneration.Seventy-two knees were evaluated on second-look arthroscopy in patients who opted for plate and screw removal at an average of 20.1 months after osteotomy. Cartilage degeneration at the patellofemoral joint was evaluated using the International Cartilage Repair Society grading system, with cases divided into progression and nonprogression groups. Radiographic parameters of the patellofemoral anatomy, knee range of motion, and clinical outcomes were evaluated from the preoperative baseline to the final follow up, on average 50 months after osteotomy. A contracture > 5° was considered a flexion contracture. Cartilage degeneration progressed in 31 knees, and preoperative knee flexion contracture was significantly associated with progressive degeneration ( P < 0.01). The Lysholm and Kujala scores were significantly lower in the progression group (87.9 and 85.3, respectively) than in the nonprogression group (91.6 and 93.6, respectively) ( P < 0.05). The odds ratio of the flexion contracture resulting in progression of patellofemoral cartilage degeneration was 4.63 (95% confidence interval, 1.77–12.1). No association was detected between progressive degeneration and age, sex, body mass index, Kellgren-Lawrence grade, or radiographic parameters. Flexion contracture may be associated with progression of cartilage degeneration at the patellofemoral joint and may negatively affect the clinical outcomes after open wedge, high tibial osteotomy.
