Publication bias assessment and Report the number of participants showed the highest effects favoring the register (RR 1.59, CI 95% 1.19-2.12; RR 1.58, CI 95% 1.31-1.92 respectively). Moreover, Registration was not significantly linked with the articles' reporting statistical significance (OR 0.96, CI 95% 0.49-1.90). CONCLUSION There is a positive influence of previously registering a protocol in the final report quality of SRs in dentistry. However, we did not observe an association between protocol registration and reduction in outcome reporting bias.BACKGROUND This case report highlights the rare occurrence of postpartum psychosis in the setting of peripartum cardiomyopathy, which can have rare presentations like arrhythmias and pulmonary edema; and the challenges one should anticipate while managing these conditions together. Caution is advised whenever antipsychotic drugs are to be administered to a patient with a cardiac condition as these drugs potentially increase the risk of arrhythmias and sudden death. CASE PRESENTATION A 35 year old grand multiparous woman who was 1 week into puerperium was admitted with severe difficulty in breathing at rest, chest congestion and pain. She also had easy fatigability, orthopnea, paroxysmal nocturnal dyspnea, edema, tachycardia, tachypnea, irregularly irregular heart rate with a pulse deficit, elevated jugular venous pressure, cardiomegaly, hepatomegaly and pulmonary crepitations. On the sixth day while improving on standard drugs for heart failure, she developed bizarre behavior and confusion. She also had auditory, visual and olfactory hallucinations; violence to the baby and the husband; and refusal to feed and take medication. There was no altered sensorium and the vital signs were normal. She was diagnosed with puerperal psychosis during the management of peripartum cardiomyopathy. CONCLUSION In the rare occurrence of puerperal psychosis in the course of management of peripartum cardiomyopathy one must be acutely aware of the risk of sudden cardiac death occasioned by use of antipsychotics, either directly or due to arrhythmias. Continuous electrocardiogram (ECG) monitoring or use of alternative management modalities is thus highly advised.BACKGROUND Systemic lupus erythematosus (SLE) can directly affect various part of the ocular system, but there was no comprehensive analysis of ophthalmic disorders of patients with SLE using population-based data. The aim of this study was to investigate the frequency and prevalence of ophthalmic disorders for ophthalmologist visits in adult patients with SLE and to evaluate the risk of dry eye syndrome, cataracts, glaucoma, episcleritis and scleritis, and retinal vascular occlusion in these patients. METHODS The Taiwan's National Health Insurance Research Database was used to assemble a SLE cohort consisting of newly diagnosed SLE between 2000 and 2012. A comparison cohort was also sampled from the same database and it consisted of 10 patients without SLE for each patient with SLE, based on frequency matching for sex, five-year age interval, and index year. Both cohorts were followed until either the study outcomes have occurred or the end of the follow-up period. RESULTS Patients with SLE (n = 521) exhibited a significantly higher prevalence (68.1% vs. 60.5%, P = 0.001) and frequency (median 5.51 vs. 1.71 per 10 years, P  less then   0.001) for outpatient ophthalmologist visits compared with patients without SLE. The risk of dry eye syndrome (adjusted incidence rate ratio [IRR] 4.45, P  less then   0.001), cataracts (adjusted IRR 3.18, P  less then   0.001), and glaucoma (adjusted IRR 2.23, P = 0.002) were significantly higher in patients with SLE. In addition, the risk of several SLE related ophthalmic disorders, including episcleritis and scleritis (adjusted IRR 6.11, P  less then   0.001) and retinal vascular occlusion (adjusted IRR 3.81, P = 0.023) were significantly higher in patients with SLE. CONCLUSIONS The increased risk of dry eye syndrome, cataracts, glaucoma, episcleritis and scleritis, and retinal vascular occlusion in patients with SLE deserves vigilance.Respiratory disturbances present in Parkinson's disease (PD) are not well understood. Thus, studies in animal models aimed to link brain dopamine (DA) deficits with respiratory impairment are needed. Adult Wistar rats were lesioned with injection of 6-hydroxydopamine (6-OHDA) into the third cerebral ventricle. Two weeks after hypoxic test was performed in whole-body plethysmography chamber, phrenic (PHR) and hypoglossal (HG) nerve activities were recorded in normoxic and hypoxic conditions in anesthetized, vagotomized, paralyzed and mechanically ventilated rats. https://www.selleckchem.com/products/primaquine.html The effects of activation and blockade of dopaminergic carotid body receptors were investigated during normoxia in anesthetized spontaneously breathing rats. 6-OHDA injection affected resting respiratory pattern in awake animals an increase in tidal volume and a decrease in respiratory rate had no effect on minute ventilation. Hypoxia magnified the amplitude and minute activity of the PHR and HG nerve of 6-OHDA rats. The ratio of pre-inspiratory to inspiratory HG burst amplitude was reduced in normoxic breathing. Yet, the ratio of pre-inspiratory time to total time of the respiratory cycle was increased during normoxia. 6-OHDA lesion had no impact on DA and domperidone effects on the respiratory pattern, which indicate that peripheral DA receptors are not affected in this model. Analysis of monoamines confirmed substantial striatal depletion of dopamine, serotonin and noradrenaline (NA) and reduction of NA content in the brainstem. In bilateral 6-OHDA model changes in activity of both nerves HG (linked with increased apnea episodes) and PHR are present. Demonstrated respiratory effects could be related to specific depletion of DA and NA.BACKGROUND Alzheimer's disease is the most common neurodegenerative disease in the elderly. Amyloid-β protein (Aβ) is the major component of neuritic plaques which are the hallmark of AD pathology. β-site APP cleaving enzyme 1 (BACE1) is the major β-secretase contributing to Aβ generation. β-site APP-cleaving enzyme 2 (BACE2), the homolog of BACE1, might play a complex role in the pathogenesis of Alzheimer's disease as it is not only a θ-secretase but also a conditional β-secretase. Dysregulation of BACE2 is observed in Alzheimer's disease. However, the regulation of BACE2 is less studied compared with BACE1, including its degradation pathways. In this study, we investigated the turnover rates and degradation pathways of BACE2 in both neuronal cells and non-neuronal cells. RESULTS Both lysosomal inhibition and proteasomal inhibition cause a time- and dose-dependent increase of transiently overexpressed BACE2 in HEK293 cells. The half-life of transiently overexpressed BACE2 protein is approximately 6 h. Moreover, the half-life of endogenous BACE2 protein is approximately 4 h in both HEK293 cells and mouse primary cortical neurons.
