IntroductionEffective treatment of new-onset headache after craniotomy, especially anterior temporal lobectomy (ATL) and amygdalohippocampectomy for drug-resistant temporal lobe epilepsy, is a challenge. The current practice, acetaminophen combined with opioids is often reported by patients as insufficient and sometimes accompanied by opioid-related adverse effects. Based on expert opinion, anaesthesiologists therefore frequently consider s-ketamine as add-on therapy. This randomised parallel group design trial compares s-ketamine with a placebo as add on medication to a multimodal pain approach.Methods and analysisIn total 62 adult participants, undergoing ATL for drug resistant epilepsy under general anaesthesia, will be randomised to either receive a 0.25 mg/kg bolus followed by a continuous infusion of 0.1 mg/kg/hour of s-ketamine or placebo (0.9% NaCl) starting before incision and continued for 48 hours as an addition to acetaminophen and opioids administered in a patient-controlled analgesia pump. The primary outcome measure is the cumulative postoperative opioid consumption. Patient recruitment started August 2018 and will end in 2021. Secondary outcome measures are postoperative pain intensity scores, psychological parameters, length of hospital stay and adverse events and will be reassessed at 3 and 6 months after surgery, with a baseline measurement preoperatively. All data are collected by researchers who are blinded to the treatment. The data will be analysed by multivariable linear mixed-effects regression.Ethics and disseminationEthical approval has been given by the local medical ethical committee (NL61666.068.17). This study will be conducted in accordance with the Dutch Medical Research Involving Human Subjects Act and the Declaration of Helsinki. The results of this trial will be publicly disclosed and submitted for publication in an international peer-reviewed scientific journal.Trial registration numberNTR6480.

Negative symptoms represent an unmet need for schizophrenia treatment. The effect of theta frequency transcranial alternating current stimulation (theta-tACS) applied during working memory (WM) tasks on negative symptoms has not been demonstrated as of yet. We conducted a randomized, double-blind, sham-controlled trial of 36 stabilized schizophrenia patients, randomized to receive either twice daily, 6 Hz 2 mA, 20 min sessions of in-phase frontoparietal tACS or sham for five consecutive weekdays. Participants were concurrently engaged in WM tasks during stimulation. The primary outcome measure was the change over time in the Positive and Negative Syndrome Scale (PANSS) negative subscale score measured from baseline through to the 1-month follow-up. Secondary outcome measures were other symptom clusters, neurocognitive performance, and relevant outcomes. The intention-to-treat analysis demonstrated greater reductions in PANSS negative subscale scores at the end of stimulation in the active (−13.84%) than the sham (−3.78%) condition, with a large effect size (Cohen’s d = 0.96, p = 0.006). The positive effect endured for at least one month. Theta-tACS also showed efficacies for cognitive symptoms, WM capacity, and psychosocial functions. Online theta-tACS offers a novel approach to modulate frontoparietal networks to treat negative symptoms of schizophrenia. The promising results require large-scale replication studies in patients with predominantly negative symptoms.

ABSTRACTBackground: Agitation and aggression in Alzheimer's disease (AD) are amongst the most serious of neuropsychiatric symptoms, and contribute to poor outcomes and worse quality of life. Previous studies have suggested a benefit for memantine on agitation and aggression, but none have examined its efficacy in community-dwelling patients with significant agitation and aggression at baseline, utilizing these behaviors as a primary outcome measure.Methods: Patients with moderate-to-severe AD with Neuropsychiatric Inventory (NPI) total score ≥13 and NPI agitation/aggression score ≥1 were randomized to placebo or 20-mg memantine in a double-blind, 24-week trial. Co-primary outcome measures were behavior, measured by total NPI score, and cognition, using the Severe Impairment Battery (SIB). Secondary outcome measures included global assessment, function and other measures of behavior. This trial was registered as Clinicaltrials.gov: NCT00857649.Results: A total of 369 patients (average age = 75, average MMSE = 12) were randomized to placebo or memantine. The study was prematurely terminated due to recruitment problems. There were no statistically significant differences between memantine and placebo in mean change from baseline in NPI, SIB, or any of the secondary outcome measures. Behavior improved in both groups (total NPI change scores −3.90 ± 1.24 for memantine and −5.13 ± 1.23 for placebo). Memantine was generally well tolerated and patient retention in both treatment arms was good.Conclusions: The study failed to show the superiority of memantine in this sample of patients with moderate-to-severe AD with significant baseline agitation and aggression. Methodological limitations could have contributed to these results.

Abstract BackgroundGeneralized anxiety disorder (GAD) is common among perimenopause women. Drug treatment and cognitive behavioral therapy have their pros and cons. Acupuncture may be an effective treatment for GAD, but evidence is limited. The pathogenesis of GAD is not yet clear, but it is related to hypothalamic-pituitary-adrenal axis and its excretion, cortisol (CORT) and adrenocorticotropic hormone (ACTH). The object of this study is to assess the efficacy of manual acupuncture (MA) versus placebo acupuncture (PA) for perimenopause women with GAD. MethodsThis study is a single center, randomized, double blind clinical trial that will be conducted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 112 eligible GAD patients will be randomly assigned (1:1) to receive MA (n=56) or PA (n=56) three times per week for four weeks. The primary outcome measure will be the score of GAD-7. The secondary outcome measures will be the score of HAMA and PSQI, and the level of CORT and ACTH. The evaluation will execute at baseline, 2 weeks, the end of the treatment and a follow-up period. All main analyses will be carried out based on the intention-to-treat (ITT) principle. DiscussionThis study intends to conduct to compare the efficacy between MA and PA in the treatment of perimenopause woman with GAD, and to further study the mechanisms of effect.

Abstract Background: Hemorrhoidal disease (HD) is one of the commonest proctologic condition in the general population. Medical therapy for HD has not been formally confirmed due to the inconsistent of results. Liang-Xue-Di-Huang Decoction, a kind of ancient Chinese classical prescription, has been used to treat HD from the 19th century in China. However, clinical research of Liang-Xue-Di-Huang Decoction in the treatment of HD is lack. We designed this study to evaluate the efficacy and safety of Liang-Xue-Di-Huang Decoction in the treatment of HD. Methods/Design: A randomized, controlled, double blind, double-mimetic agent and multicenter trial to evaluate the efficacy and safety of Liang-Xue-Di-Huang Decoction is proposed. HD patients (stage I, Ⅱ, Ⅲ) will be randomly assigned into Liang-Xue-Di-Huang Decoction with the addition of Diosmine mimetic agent, or Diosmine with the addition of Liang-Xue-Di-Huang Decoction mimetic agent. Patients will receive a 7-days treatments and a 7-days follow-up. The primary outcome measure is the French Bleeding Score in 7 and 14 days. The Secondary outcome measures are Goligher Prolapse Score and Quality-of-Life Score in 7 and 14 days. Discussion: This study will provide objective evidence to evaluate the efficacy and safety of Liang-Xue-Di-Huang Decoction in treatment of HD. Trial registration: Chinese Clinical Trial Registry.

Polygonatum sibiricum (PS) rhizome, which contains glyceryl-1-monolinoleate as its primary active component, has been shown to improve insomnia in animal models. Based on these findings, we aimed to investigate the safety and efficacy of PS rhizome extract in improving sleep quality in individuals with mild insomnia. Eighty individuals with mild insomnia were enrolled in a four-week, randomized, double-blind, placebo-controlled trial of PS rhizome extract (500 mg/day, n = 40, PS group) or placebo (n = 40, placebo group). The primary outcome measure was change in total score on the Athens Insomnia Scale (AIS) to indicate sleep quality. The secondary outcome measures included change in actigraphy data and perfusion levels in the brain regions within the default mode network (DMN), which is known to play a key role in insomnia. The PS group showed greater improvement in the total AIS score with a significant increase in total sleep time, relative to the placebo group. In addition, significant group-by-visit interactions were observed in the perfusion level of the medial prefrontal cortex within the DMN. Findings of the current study provide first evidence that PS rhizome extract could be an effective natural ingredient for improving sleep in mild insomnia using a human model.

Abstract Introduction and hypothesis Urinary incontinence (UI) is common in women who exercise. We aimed to investigate new onset UI in formerly inactive, overweight or obese women (BMI > 25) participating in three different strength training modalities compared with a non-exercising control group. Methods This was a secondary analysis of an assessor blinded randomized controlled trial investigating the effect of 12 weeks of three strength training concepts for women on muscle strength and body composition. None of the programs included pelvic floor muscle training. International Consensus on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI-SF) was used to investigate primary outcome; new onset UI, and secondary outcome; ICIQ-UI-SF sum score. Suissa and Shuster’s exact unconditional test was used to analyze difference in new onset UI. Difference in ICIQ-UI-SF sum score is presented as mean with 95% CI. Results At baseline 40 out of 128 (31.2%) participants reported UI. Three out of 27, 2 out of 17, 2 out of 23, and 0 out of 21 women in the three training and control groups respectively had new onset UI. There were no statistically significant differences in new onset UI across the groups or when collapsing new onset UI in the intervention groups compared with the controls (7 out of 67 vs 0 out of 21), p = 0.124. After the intervention the control group reported worse ICIQ-UI-SF sum score than any of the training groups; mean difference − 6.6 (95% CI: −11.9, −1.27), p = 0.012, but there was no difference in change from baseline to 12 weeks between the groups p = 0.145). Conclusions There was no statistically significant change in UI after strength training.

A recent animal study demonstrated that administration of Lactobacillus plantarum HAC01 isolated from Korean kimchi improved glycemic control in type 2 diabetic mice. In the present study, we evaluated Lactobacillus plantarum HAC01’s effects on metabolic parameters of prediabetic human subjects. Forty subjects with isolated impaired glucose tolerance were randomly assigned to receive a daily placebo (n = 20) or a dose of Lactobacillus plantarum HAC01 (n = 20) over eight weeks. The primary endpoint was a change in 2 h postprandial glucose (2h-PPG) levels and the secondary endpoints were assessment of other glucose metabolism parameters, including HbA1c, gut microbiota composition, and fecal short-chain fatty acids (SCFAs). The group with a diet supplemented with Lactobacillus plantarum HAC01 saw a significant reduction in 2h-PPG and HbA1c levels compared to the placebo group. Fasting plasma glucose, insulin, HOMA-IR, QUICKI, microbiota composition, and fecal SCFAs, however, were not significantly altered. No serious adverse effects were reported. This is the first clinical trial to show a beneficial effect of single-strain probiotic supplementation administered over eight weeks on HbA1c levels in prediabetic subjects.

AbstractConvalescent plasma (CP) therapy in COVID-19 disease may improve clinical outcome in severe disease. This pilot study was undertaken to inform feasibility and safety of further definitive studies. This was a prospective, interventional and randomized open label pilot trial in patients with severe COVID-19. Twenty COVID-19 patients received two 200 ml transfusions of convalescent patient CP over 24-h compared with 20 who received standard of care. The primary outcome was the requirement for ventilation (non-invasive or mechanical ventilation). The secondary outcomes were biochemical parameters and mortality at 28 days. The CP group were a higher risk group with higher ferritin levels (p < 0.05) though respiratory indices did not differ. The primary outcome measure was required in 6 controls and 4 patients on CP (risk ratio 0.67, 95% CI 0.22–2.0, p = 0.72); mean time on ventilation (NIV or MV) did not differ. There were no differences in secondary measures at the end of the study. Two patients died in the control and one patient in the CP arm. There were no significant differences in the primary or secondary outcome measures between CP and standard therapy, although a larger definitive study is needed for confirmation. However, the study did show that CP therapy appears to be safe in hospitalized COVID-19 patients with hypoxia.Clinical trials registration NCT04356534: 22/04/2020.

ObjectivesMethotrimeprazine is commonly used for the management of nausea but never tested formally against other drugs used in this setting. The aim was to demonstrate superior antiemetic efficacy.DesignDouble-blind, randomised, controlled trial of methotrimeprazine versus haloperidol.Setting11 palliative care sites in Australia.ParticipantsParticipants were >18 years, had cancer, an average nausea score of ≥3/10 and able to tolerate oral medications. Ineligible patients had acute nausea related to treatment, nausea for which a specific antiemetic was indicated, were about to undergo a procedure or had received either of the study drugs or a change in glucocorticoid dose within the previous 48 hours.InterventionsBased on previous studies, haloperidol was used as the control. Participants were randomised to encapsulated methotrimeprazine 6·25 mg or haloperidol 1·5 mg one time or two times per day and assessed every 24 hours for 72 hours.Main outcome measuresA ≥two-point reduction in nausea score at 72 hours from baseline. Secondary outcome measures were as follows: complete response at 72 hours (end nausea score less than 3), response at 24 and 48 hours, vomiting episodes, use of rescue antiemetics, harms and global impression of change.ResultsResponse to treatment at 72 hours was 75% (44/59) in the haloperidol (H) arm and 63% (36/57) in the methotrimeprazine (M) arm with no difference between groups (intention-to-treat analysis). Complete response rates were 56% (H) and 51% (M). In theper protocolanalysis, there was no difference in response rates: (85% (44/52) (H) and 74% (36/49) (M). Completeper protocolresponse rates were 64% (H) and 59% (M). Toxicity worse than baseline was minimal with a trend towards greater sedation in the methotrimeprazine arm.ConclusionThis study did not demonstrate any difference in response rate between methotrimeprazine and haloperidol in the control of nausea.Trial registration numberACTRN 12615000177550.
