Prophylaxis for paediatric emergence delirium in desflurane-based anaesthesia: a network meta-analysis

PURPOSE

The prevalence of postoperative emergence delirium in paediatric patients (pedED) following desflurane anaesthesia is considerably high at 50-80%. Although several pharmacological prophylactic strategies have been introduced to reduce the risk of pedED, conclusive evidence about the superiority of these individual regimens is lacking. The aim of the current study was to assess the potential prophylactic effect and safety of individual pharmacotherapies in the prevention of pedED following desflurane anaesthesia.

METHODS

This frequentist model network meta-analysis (NMA) of randomized controlled trials (RCTs) included peer-reviewed RCTs of either placebo-controlled or active-controlled design in paediatric patients under desflurane anaesthesia.

RESULTS

Seven studies comprising 573 participants were included. Overall, the ketamine + propofol administration [odds ratio (OR) = 0.05, 95% confidence intervals (95%CIs) 0.01-0.33], dexmedetomidine alone (OR = 0.13, 95%CIs 0.05-0.31), and propofol administration (OR = 0.30, 95%CIs 0.10-0.91) were associated with a significantly lower incidence of pedED than the placebo/control groups. In addition, only gabapentin and dexmedetomidine were associated with a significantly higher improvement in the severity of emergence delirium than the placebo/control groups. Finally, the ketamine + propofol administration was associated with the lowest incidence of pedED, whereas gabapentin was associated with the lowest severity of pedED among all of the pharmacologic interventions studied.

CONCLUSIONS

The current NMA showed that ketamine + propofol administration was associated with the lowest incidence of pedED among all of the pharmacologic interventions studied. Future large-scale trials to more fully elucidate the comparative benefits of different combination regimens are warranted.

High Dosage Omega-3 Fatty Acids Outperform Existing Pharmacological Options for Migraine Prophylaxis: A Network Meta-Analysis

Migraine is a highly prevalent neurologic disorder with prevalence rates ranging from 9% to 18% worldwide. Current pharmacologic prophylactic strategies for migraine have limited efficacy and acceptability, with relatively low response rates of 40% to 50% and limited safety profiles. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are considered promising therapeutic agents for migraine prophylaxis. The aim of this network meta-analysis (NMA) was to compare the efficacy and acceptability of various dosages of EPA/DHA and other current Food and Drug Administration-approved or guideline-recommended prophylactic pharmacologic interventions for migraine. Randomized controlled trials (RCTs) were eligible for inclusion if they enrolled participants with a diagnosis of either episodic or chronic migraine. All NMA procedures were conducted under the frequentist model. The primary outcomes assessed were 1) changes in migraine frequency and 2) acceptability (i.e., dropout for any reason). Secondary outcomes included response rates, changes in migraine severity, changes in the frequency of using rescue medications, and frequency of any adverse events. Forty RCTs were included (N = 6616; mean age = 35.0 y; 78.9% women). Our analysis showed that supplementation with high dosage EPA/DHA yields the highest decrease in migraine frequency [standardized mean difference (SMD): -1.36; 95% confidence interval (CI): -2.32, -0.39 compared with placebo] and the largest decrease in migraine severity (SMD: -2.23; 95% CI: -3.17, -1.30 compared with placebo) in all studied interventions. Furthermore, supplementation with high dosage EPA/DHA showed the most favorable acceptability rates (odds ratio: 1.00; 95% CI: 0.06, 17.41 compared with placebo) of all examined prophylactic treatments. This study provides compelling evidence that high dosage EPA/DHA supplementation can be considered a first-choice treatment of migraine prophylaxis because this treatment displayed the highest efficacy and highest acceptability of all studied treatments. This study was registered in PROSPERO as CRD42022319577.

Omega-3 polyunsaturated fatty acids in sarcopenia management: A network meta-analysis of randomized controlled trials

Sarcopenia frequently occurs with aging and leads to major adverse impacts on activities of daily living and quality of life in elderly individuals. Omega-3 polyunsaturated fatty acid (omega-3 PUFAs) supplements are considered promising therapeutic agents for sarcopenia management; however, the evidence remains inconsistent. We reviewed randomized controlled trials (RCTs) about omega-3 PUFA supplementation in patients with sarcopenia or in those at high risk for sarcopenia. Network meta-analysis (NMA) procedures were conducted using a frequentist model. The primary outcomes were (1) upper-extremity muscle strength and (2) lower-extremity physical function. The NMA of 16 RCTs showed that the high-dose (more than 2.5 g/day omega-3 PUFAs) group yielded the greatest improvement in both upper-extremity muscle strength and lower-extremity physical function [compared to placebo/standard care groups, standardized mean difference (SMD)= 1.68, 95% confidence interval (95%CI)= 0.03-3.33, and SMD= 0.73, 95%CI= 0.16-1.30, respectively], and the effects were reaffirmed in subgroup analyses of placebo-controlled RCTs or those excluding concurrent resistance training programs. None of the investigated omega-3 PUFAs supplementation was associated with significantly increased skeletal muscle mass, fat mass, or overall body weight. Our findings provide a basis for future large-scale RCTs to investigate the dose effects and clinical application of omega-3 PUFA supplementation in sarcopenia management. TRIAL REGISTRATION: The current study was approved by the Institutional Review Board of the Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan (TSGHIRB No. B-109-29) and registered in PROSPERO (CRD42022347161).

Efficacy and acceptability of anti-inflammatory eicosapentaenoic acid for cognitive function in Alzheimer's dementia: A network meta-analysis of randomized, placebo-controlled trials with omega-3 fatty acids and FDA-approved pharmacotherapy

Alzheimer's dementia (AD) is a major contributor to global disability, and effective therapies to modify disease progression are currently lacking. The neuro-inflammatory theory is a potential etiology underlying this neurodegenerative disease. Previous randomized, controlled trials (RCTs) have provided inconclusive results regarding efficacy of omega-3 polyunsaturated fatty acids (PUFAs) regimens, which might provide anti-inflammatory benefits in the management of AD, in improving cognitive function among participants with AD. The objective of this frequentist-model based network meta-analysis (NMA) was to evaluate the potential advantages of omega-3 PUFAs and currently FDA-approved medications for AD on overall cognitive function in AD individuals. The primary outcomes were: (1) changes in cognitive function, and (2) acceptability, which refers to all-cause discontinuation. Additionally, secondary outcomes included quality of life, behavioral disturbances and safety/tolerability, which was assessed through the frequency of any reported adverse event. This NMA included 52 RCTs (6 with omega-3 PUFAs and 46 with FDA-approved medications) involving 21,111 participants. The results showed that long-term high-dose (1500-2000 mg/day) of eicosapentaenoic acid (EPA)-dominant omega-3 PUFAs augmented with anti-oxidants had the highest potential for cognitive improvement among all investigated treatments [standardized mean difference = 3.00, 95% confidence intervals (95 %CIs) = 1.84-4.16]. Compared to placebo, omega-3 PUFAs had similar acceptability [odds ratio (OR) = 0.46, 95 %CIs = 0.04 to 5.87] and safety profiles (OR = 1.24, 95 %CIs = 0.66 to 2.33)o. These findings support the potential neurotherapeutic effects of high dosage EPA-dominant omega-3 PUFAs for the amelioration of cognitive decline in patients with AD. Future large-scale, long-term RCTs should focus on different dosages of EPA-dominant omega-3 PUFAs regimens on improving cognitive dysfunction in patients with AD at different levels of inflammatory status and psychopathology.

Black cohosh extracts in women with menopausal symptoms: an updated pairwise meta-analysis

OBJECTIVE

Menopausal symptoms are common in midlife women and have broad impacts on their daily functioning and quality of life. Black cohosh extracts have been widely used to relieve menopausal symptoms. However, the comparative benefits of different combined black cohosh regimens remain inconclusive. The aim of the current updated meta-analysis is to address the comparative efficacies of different black cohosh regimens in improving menopausal symptoms.

METHODS

Random-effect model pairwise meta-analysis of randomized controlled trials was conducted to investigate the treatment effect on menopausal symptoms by the black cohosh extract both alone or combined with other related active ingredients. The outcomes studied were changes in menopausal symptoms after treatment with black cohosh extracts in menopausal women.

RESULTS

Twenty-two articles including information on 2,310 menopausal women were included in the analyses. Black cohosh extracts were associated with significant improvements in overall menopausal symptoms (Hedges' g = 0.575, 95% CI = 0.283 to 0.867, P < 0.001), as well as in hot flashes (Hedges' g = 0.315, 95% CIs = 0.107 to 0.524, P = 0.003), and somatic symptoms (Hedges' g = 0.418, 95% CI = 0.165 to 0.670, P = 0.001), compared with placebo. However, black cohosh did not significantly improve anxiety (Hedges' g = 0.194, 95% CI = -0.296 to 0.684, P = 0.438) or depressive symptoms (Hedges' g = 0.406, 95% CI = -0.121 to 0.932, P = 0.131). The dropout rate for black cohosh products was similar to that for placebo (odds ratio = 0.911, 95% CI = 0.660 to 1.256, P = 0.568).

CONCLUSIONS

This study provides updated evidence regarding the potentially beneficial effects of black cohosh extracts for relieving menopausal symptoms in menopausal women.

Online mental health services during COVID-19 pandemic in Indonesia: Challenges from psychologist perspective

COVID-19 are causing many psychological impacts and change many aspects of human life. Mental health services also experiencing changes because of COVID-19 outbreak. In Indonesia, COVID-19 outbreak prompted the rapid development of online mental health services. These online mental health services which will help people to connect with professional mental healthcare providers using technology were created in response to this pandemic. Therefore, converting mental health services into online services in a state of urgency is challenging. This qualitative case study aims to provide a map of the service challenges that professional healthcare providers face while providing online services at present time by interviewing eight Indonesian psychologists as one of the mental health professionals who provided the online mental health services. Semi-structured interviews were done using interview guidelines with open-ended questions, and any other complementary data was collected using questionnaire. The data gathered from interviews was first performed through triangulation and then analyzed using thematic network analysis, which resulted in the following challenges: (1) building engagement; (2) risk of getting distracted during the sessions; (3) maintaining professional boundaries during the sessions; (4) keeping the personal information and confidentiality of the sessions; (5) perceived efficacy; and (6) attitudes towards online sessions. According to the results, the relevant organization can use this finding to contribute and develop the online mental health services both in this COVID-19 situation and in the future.

Pharmacological interventions and hormonal therapies for depressive symptoms in peri- and post-menopausal women: a network meta-analysis of randomized controlled trials

Although significant portion of women experience depressive symptoms during or after menopausal transition, there has been considerable controversy over the benefits of hormone replacement therapy (HRT) and antidepressants due to insufficient evidence supporting the superiority of either treatment. This frequentist model based network meta-analysis (NMA) included randomized controlled trials (RCTs) of menopausal depression symptoms management in menopausal women. Seventy RCTs involving a total of 18,530 women (mean age 62.5) were analyzed. The results demonstrated that fluoxetine plus oral HRT [standardized mean difference (SMD)=-1.59, 95% confidence interval (95%CIs)=-2.69 to -0.50] were associated with the largest improvement in depressive symptoms than placebos in overall menopausal women. Similar findings were also noted in the subgroup of participants with a definite diagnosis of depression, while no pharmacological or hormone replacement therapy was better than placebo in the subgroup of post-menopausal women (amenorrhea > 1 year) or in patients without diagnosis of depression. This NMA presented evidence that fluoxetine plus HRT may be beneficial to menopausal women with a definite diagnosis of depression but not to those without depression or post-menopausal women. Trial registration: PROSPERO (CRD42020167459).

The beneficial effect on cognition of noninvasive brain stimulation intervention in patients with dementia: a network meta-analysis of randomized controlled trials

BACKGROUND

Dementia [i.e., Alzheimer disease (AD)], the most common neurodegenerative disease, causes profound negative impacts on executive function and quality of life. Available pharmacological treatments often fail to achieve satisfactory outcomes. Noninvasive brain stimulation (NIBS) techniques, which focally modify cortical function and enhance synaptic long-term potentiation, are potentially beneficial for the cognition in patients with AD. The aim of the current network meta-analysis (NMA) was to evaluate the efficacy and safety of different NIBS interventions in patients with AD through NMA.

METHODS

Only randomized controlled trials (RCTs) examining NIBS interventions in patients with AD had been included. All NMA procedures were performed under the frequentist model. The primary and secondary outcomes were changes in cognitive function and quality of life, respectively.

RESULTS

Nineteen RCTs (639 participants) were included. The mean treatment and follow-up durations were 5.7 and 10.5 weeks, respectively. The combination of cathodal tDCS of the left dorsolateral prefrontal cortex and anodal tDCS over the right supraorbital region (c-tDCS-F3 + a-tDCS-Fp2) was associated with a significant beneficial effect on cognition compared with sham controls (standardized mean difference=2.43, 95% confidence interval=0.61-4.26, n=12 and 11). It was also associated with the greatest beneficial effect on cognition among all the investigated NIBS approaches. All the methods were well tolerated with regard to the safety profile, as reflected in the rates of adverse events or local discomfort, as well as acceptability, as indicated by dropout rate.

CONCLUSIONS

The present findings provide evidence of the benefits of NIBS, especially tDCS, for beneficial effect on cognition in patients with AD. However, because of few studies included, this effect was not replicated yet in the other studies. Therefore, future larger-scale and longer follow-up duration RCTs should be warranted.

Multiple comparison of different noninvasive brain stimulation and pharmacologic interventions in patients with methamphetamine use disorders: A network meta-analysis of randomized controlled trials

AIM

In recent decades, the prevalence of amphetamine and methamphetamine use disorders has at least doubled in some regions/countries, with accompanying high risks of drug overdose-associated mortality. Noninvasive brain stimulation (NIBS) methods may be effective treatments. However, the comparative efficacy of the NIBS protocol for amphetamine/methamphetamine use disorder (AUD/MUD) remains unknown to date. The aim of this network meta-analysis (NMA) was to compare the efficacy and acceptability of various NIBS methods/protocols for AUD/MUD management.

METHODS

A frequentist model-based NMA was conducted. We included randomized controlled trials (RCTs) that investigated the efficacy of NIBS and guideline-recommended pharmacologic treatments to reduce craving severity in patients with either AUD or MUD.

RESULTS

Twenty-two RCTs including 1888 participants met the eligibility criteria. Compared with the sham/placebo group (study = 19, subjects = 891), a combination of intermittent theta burst stimulation over the left dorsolateral prefrontal cortex (DLPFC) and continuous TBS over the left ventromedial prefrontal cortex (study = 1, subjects = 19) was associated with the largest decreases in craving severity [standardized mean difference (SMD) = -1.50; 95% confidence intervals (95%CIs) = -2.70 to -0.31]. High-frequency repetitive transcranial magnetic stimulation over the left DLPFC was associated with the largest improvements in depression and quality of sleep (study = 3, subjects = 86) (SMD = -2.48; 95%CIs = -3.25 to -1.71 and SMD = -2.43; 95%CIs = -3.38 to -1.48, respectively). The drop-out rate of most investigated treatments did not significantly differ between groups.

CONCLUSION

The combined TBS protocol over the prefrontal cortex was associated with the greatest improvement in craving severity. Since few studies were available for inclusion, additional large-scale randomized controlled trials are warranted.

Size reduction of the right amygdala in chronic pain patients with emotional stress: A systematic review and meta-analysis

The structural impact of chronic pain on amygdala in chronic pain (CP) patients remains unclear although major depression and anxiety are known to be associated with its increase and decrease in size, respectively. This study aimed at examining the relationship between emotional stress and amygdala size in CP patients. The effects of mediating and moderating variables were also examined. The PubMed, Embase, and Web of Science databases were searched for English clinical trials from inception to February 2022 using the appropriate keyword strings. We compared the differences in amygdala size assessed with magnetic resonance imaging between CP patients with emotional stress and healthy counterparts. Of the 49 full-text articles identified, 13 studies enrolling 1551 participants including 738 CP patients with emotional stress and 813 controls were analyzed. Emotional stress evaluated with questionnaires based on Beck depression inventory, Hamilton depression/anxiety scale, state-trait anxiety inventory, and hospital anxiety and depression scale revealed significant differences between CP patients with emotional stress and controls, indicating a subclinical but significant level of emotional stress in CP patients. The results demonstrated an amygdala shrinkage among CP patients with emotional stress compared to the controls, especially the right side (p = 0.02). Besides, pain from a single body region was more likely to impact the amygdala size compared to diffuse pain (p = 0.02). Regression analysis revealed no significant association between continuous variables (age, gender, pain duration/intensity) and amygdala size. Our findings demonstrated that emotional stress was associated with a reduced right amygdala size in CP patients.

This study can control mental illness based on spirituality theory and practice.

Assessment of Noninvasive Brain Stimulation Interventions for Negative Symptoms of Schizophrenia: A Systematic Review and Network Meta-analysis

IMPORTANCE

Negative symptoms have a detrimental impact on functional outcomes and quality of life in people with schizophrenia, and few therapeutic options are considered effective for this symptomatic dimension. Studies have suggested that noninvasive brain stimulation (NIBS) interventions may be effective in treating negative symptoms. However, the comparative efficacy of different NIBS protocols for relieving negative symptoms remains unclear.

OBJECTIVE

To compare the efficacy and acceptability of different NIBS interventions for treating negative symptoms.

DATA SOURCES

The ClinicalKey, Cochrane CENTRAL, Embase, ProQuest, PubMed, ScienceDirect, ClinicalTrials.gov, and Web of Science electronic databases were systematically searched from inception through December 7, 2021.

STUDY SELECTION

A frequentist model network meta-analysis was conducted to assess the pooled findings of trials that evaluated the efficacy of repetitive transcranial magnetic stimulation (rTMS), theta-burst stimulation, transcranial random noise stimulation, transcutaneous vagus nerve stimulation, and transcranial direct current stimulation on negative symptoms in schizophrenia. Randomized clinical trials (RCTs) examining NIBS interventions for participants with schizophrenia were included.

DATA EXTRACTION AND SYNTHESIS

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed. Data were independently extracted by multiple observers. The pair-wise meta-analytic procedures were conducted using a random-effects model.

MAIN OUTCOMES AND MEASURES

The coprimary outcomes were changes in the severity of negative symptoms and acceptability (ie, dropout rates owing to any reason). Secondary outcomes were changes in positive and depressive symptoms.

RESULTS

Forty-eight RCTs involving 2211 participants (mean [range] age, 38.7 [24.0-57.0] years; mean [range] proportion of female patients, 30.6% [0%-70.0%]) were included. Compared with sham control interventions, excitatory NIBS strategies (standardized mean difference [SMD]: high-definition transcranial random noise stimulation, -2.19 [95% CI, -3.36 to -1.02]; intermittent theta-burst stimulation, -1.32 [95% CI, -1.88 to -0.76]; anodal transcranial direct current stimulation, -1.28 [95% CI, -2.55 to -0.02]; high-frequency rTMS, -0.43 [95% CI, -0.68 to -0.18]; extreme high-frequency rTMS, -0.45 [95% CI, -0.79 to -0.12]) over the left dorsolateral prefrontal cortex with or without other inhibitory stimulation protocols in the contralateral regions of the brain were associated with significantly larger reductions in negative symptoms. Acceptability did not significantly differ between the groups.

CONCLUSIONS AND RELEVANCE

In this network meta-analysis, excitatory NIBS protocols over the left dorsolateral prefrontal cortex were associated with significantly large improvements in the severity of negative symptoms. Because relatively few studies were available for inclusion, additional well-designed, large-scale RCTs are warranted.

The efficacy and tolerability of antibiotics in scrub typhus: An updated network meta-analysis of randomized controlled trials

INTRODUCTION

Inadequate treatment of scrub typhus results in severe complications such as septic shock and is also associated with a high median mortality rate of 6%. However, there has been no conclusive evidence about the superiority of different antibiotics in managing scrub typhus in terms of efficacy and tolerability.

METHODS

The current network meta-analysis (NMA) was conducted using the frequentist method. The included participants were pediatric and adult patients infected with scrub typhus. The primary outcome was the cure rate in the patients included. The subgroup analysis was done according to pediatric or adult patients.

RESULTS

Overall, 14 randomized controlled trials (RCTs) with 1264 participants were included in this study. The NMA revealed that all the investigated antibiotics were associated with cure rates similar to those of doxycycline. The chloramphenicol and minocycline were ranked to be associated with the highest cure rate in the pediatric subgroup and adult subgroup, respectively. Second-generation quinolones, including ofloxacin and ciprofloxacin and chloramphenicol were associated with significantly lower adverse event rates than doxycycline.

CONCLUSION

The current update NMA provides evidence for the efficacy of chloramphenicol and minocycline in scrub typhus management. However, future large-scale RCTs with longer follow-up times are warranted.

Effectiveness and acceptability of noninvasive brain and nerve stimulation techniques for migraine prophylaxis: a network meta-analysis of randomized controlled trials

BACKGROUND

Current pharmacologic prophylactic strategies for migraine have exhibited limited efficacy, with response rates as low as 40%-50%. In addition to the limited efficacy, the acceptability of those pharmacologic prophylactic strategies were unacceptable. Although noninvasive brain/nerve stimulation strategies may be effective, the evidence has been inconsistent. The aim of this network meta-analysis (NMA) was to compare strategies of noninvasive brain/nerve stimulation for migraine prophylaxis with respect to their effectiveness and acceptability.

METHODS

The PubMed, Embase, ScienceDirect, ProQuest, ClinicalTrials.gov , ClinicalKey, Cochrane CENTRAL, Web of Science, and ClinicalTrials.gov databases were systematically searched to date of June 4th, 2021 for randomized controlled trials (RCTs). Patients with diagnosis of migraine, either episodic migraine or chronic migraine, were included. All NMA procedures were conducted under the frequentist model.

RESULTS

Nineteen RCTs were included (N = 1493; mean age = 38.2 years; 82.0% women). We determined that the high frequency repetitive transcranial magnetic stimulation (rTMS) over C3 yielded the most decreased monthly migraine days among all the interventions [mean difference = - 8.70 days, 95% confidence intervals (95%CIs): - 14.45 to - 2.95 compared to sham/control groups]. Only alternating frequency (2/100 Hz) transcutaneous occipital nerve stimulation (tONS) over the Oz (RR = 0.36, 95%CIs: 0.16 to 0.82) yielded a significantly lower drop-out rate than the sham/control groups did.

CONCLUSIONS

The current study provided a new direction for the design of more methodologically robust and larger RCTs based on the findings of the potentially beneficial effect on migraine prophylaxis in participants with migraine by different noninvasive brain/nerve stimulation, especially the application of rTMS and tONS.

Trends and Gender Differences in Mental Disorders in Hospitalized Patients in Thailand

Previous studies have shown that gender differences play a substantial role in the influence of mental disorders. This study was designed to investigate gender differences in mental disorders by presenting odd ratio (OR) trends and cumulative effects over a period of 13 years in Thailand. This observational study used hospital data from the Ministry of Public Health on selected patients admitted to inpatient departments in public hospitals with mental disorders, according to ICD-10 cause groups from 2007 to 2019, counting from more than 1,90,000 cases in 2007 to more than 4,00,000 cases in 2019. Data were collected from the Thailand Ministry of Public Health website. The results indicate that compared to women, men were positively related to five mental disorders revealed by the OR and the ratio per 100,000 population (mean and SD): psychoactive alcohol use (OR = 7.31-9.07, 271.19 (59.26)), substance abuse (OR = 5.06-7.82, 59.25 (33.71)), schizophrenia (OR = 1.64-1.93, 108.32 (19.62)), mental retardation (OR = 1.15-1.58, 10.64 (1.88)), and other mental and behavioral disorders (OR = 1.10-1.55, 70.67 (22.75)). Three mental disorders in men were found to be negatively related: neurotic and related disorders (OR=.34-.46, 27.98 (3.26)), mood (affective) disorders (OR = .44-.56, 31.91 (9.59)), and dementia (OR = .78-10.82, 13.75 (2.73)). Gender can become a key biological element that contributes to the dissimilarity of mental illness. Preventive care for men and women should, therefore, be prioritized for health conditions separately. More specifically, screening and detection, and providing appropriate intervention.

The COVID-19 pandemic and healthcare workers psychological well-being: a cross-sectional survey in Indonesia

Aim

This study was conducted to investigate the relationships amongst psychological well‐being (PWB), emotional intelligence and coping strategies.

Design

This study employed a cross‐sectional survey design.

Method

A total of 146 healthcare workers (HCWs) were enrolled in this study. They were asked to finish several questionnaires, including the Wong and Law Emotional Intelligence Scale, the Brief‐Coping Orientation to Problems Experienced Scale and the PWB Scale. The obtained data were analysed using partial least squares structural equation modelling, employee SmartPLS, to estimate the contributions of influencing factors and evaluate the moderating effect of coping strategy (CS) on the relationship between emotional intelligence and PWB.

Results

Results revealed that emotional intelligence influenced PWB, and CS moderated both emotional intelligence and PWB. Furthermore, CS plays an essential role in improving PWB related to emotional intelligence amongst HCWs during the COVID‐19 outbreak.

Efficacy of Different Interventions to Reduce Pre- or Perioperative Blood Transfusion Rate in Patients with Colorectal Cancer: A Network Meta-Analysis of Randomized Controlled Trials

Background: The high proportion of blood transfusions before and during surgery carries unnecessary risk and results in poor prognosis in colorectal cancer patients. Different pharmacological interventions (i.e., iron supplement or recombinant erythropoietin) to reduce blood transfusion rates have shown inconclusive results. Methods: This network meta-analysis (NMA) consisted of randomized controlled trials (RCTs) comparing the efficacy of different pharmacologic interventions (i.e., iron supplementation or recombinant erythropoietin) to reduce the blood transfusion rate. NMA statistics were conducted using the frequentist model. Results: Seven RCTs (688 participants) were included in this study. The NMA demonstrated that the combination of high-dose recombinant human erythropoietin and oral iron supplements was associated with the least probability of receiving a blood transfusion [odds ratio = 0.24, 95% confidence intervals (95% CIs): 0.08 to 0.73] and best reduced the amount of blood transfused if blood transfusion was necessary (mean difference = −2.62 U, 95% CI: −3.55 to −1.70 U) when compared to the placebo/control group. None of the investigated interventions were associated with any significantly different dropout rate compared to the placebo/control group. Conclusions: The combination of high-dose recombinant human erythropoietin and oral iron supplements might be considered as a choice for reducing the rate of blood transfusion in patients with colorectal cancer. However, future large-scale RCT with long-term follow-up should be warranted to approve the long-term safety.

Gender differences in geriatric syndromes as mental illness and nervous system diseases in hospitalized Thai older patients

BACKGROUND

Older persons are affected by mental and neurological disorders differently, and gender plays a significant role influencing geriatric disorder differentiation. Accordingly this study characterized gender differences in geriatric syndromes among hospitalized elderly Thai patients.

METHODS

Probabilities of disease occurrence reflecting gender differences were calculated using historical data obtained from the Ministry of Public Health website, Thailand. We selected older patients aged 60 years and above admitted to inpatient departments in public hospitals with mental disorders and nervous system diseases from 2014 to 2018, counting over 160 000 cases each year. Descriptive statistics and odds ratios (ORs) were used to analyse and demonstrate gender differences.

RESULTS

Compared to older females, older males had higher occurrences of four mental disorders revealed by OR and 95% confidence interval (CI) values: substance abuse (5.74, 5.08-6.49), alcohol use (5.66, 5.44-5.89), behavioural problems (1.34, 1.31-1.37), and schizophrenia (1.10, 1.06-1.14). Lower incidences for older males were seen in the same values for three mental disorders: neurotic issues (0.46, 0.44-0.49), mood disorders (0.58, 0.56-0.60), and dementia (0.91, 0.88-0.94). For neurological disorders, men had similar higher incidences for epilepsy (1.67, 1.63-1.72), cerebral palsy (1.61, 1.57-1.65), nervous system inflammatory diseases (1.53, 1.46-1.60), ischaemic attacks (1.42, 1.36-1.48), miscellaneous other nervous disorders (1.20; 1.18-1.22), and Parkinson's disease (1.15, 1.12-1.19). By contrast, older men had lower incidences of multiple sclerosis (0.55, 0.35-0.86), migraines (0.66, 0.62-0.70), and Alzheimer's disease (0.75, 0.71-0.78).

CONCLUSION

Accurate characterization of gender differences in geriatric syndromes can better inform policies for appropriate early detection and prevention, and contribute to the development of treatment and intervention for various issues affecting elderly men and women's health.

Pulmonary hemorrhage. A fatal manifestation in IgA nephropathy

Two patients with asymptomatic IgA nephropathy (IgAN) and a third patient with chronic renal failure due to IgAN died following a recent onset of dyspnea, hemoptysis, and pulmonary infiltrates. In all cases, the cause of death was respiratory failure attributed to either bronchopneumonia or pulmonary edema. However, no infectious agent was identified. In all three patients, the diagnoses of IgAN and idiopathic pulmonary hemorrhage were established at postmortem examination. Acute alveolar hemorrhage was present in two patients. All three patients had heavy alveolar hemosiderin-laden macrophages, and capillaritis was recognized in two of them. The occurrence of fatal pulmonary hemorrhage in patients with IgAN is rare. Our findings suggested an immune complex-mediated pulmonary injury that was possibly related to the systemic nature of IgAN.

Nasopharyngeal carcinoma: genetic changes, Epstein-Barr virus infection, or both. A clinical and molecular study of 36 patients

BACKGROUND

The pathogenesis of nasopharyngeal carcinoma has been under intense investigation, especially of its peculiar predominance in southern China. The authors previously reported consistent loss of genetic material on the short arm of chromosome 3 in a few nasopharyngeal carcinoma cases. In this study, the authors examined the genetic changes as well as the presence of Epstein-Barr virus (EBV) genome on 36 nasopharyngeal carcinoma primary biopsy specimens of the undifferentiated type and the correlation of the findings to patients' clinical status.

METHODS

The authors examined the DNA from tumor tissue and from matched blood leukocytes of 36 patients who suffered from nasopharyngeal carcinoma by the restriction fragment length polymorphism analysis. The genotyping for EBV was carried out by polymerase chain reaction using primers complementary to both types of EBV and probes specific to EBNA-2A (EBV-A) or EBNA-2B (EBV-B).

RESULTS

A consistent deletion at two specific locus of the short arm of chromosome 3 was observed in all informative cases. The authors also found that EBV genome, especially type A, was present in 35 of 36 cases. In the remaining one case, EBV-B was detected.

CONCLUSIONS

As the same tumor tissue was used for both genetic and viral studies in each case, the results may represent sequential genetic lesions in the pathogenesis and/or summation of genetic events. Moreover, 7 of 32 informative tumors were from patients of early staging (Stages I and II), which suggests the genetic changes may occur in the early development of nasopharyngeal carcinoma. Difference in allele frequency in specific locus was also noted between Asian and white patients for the first time.

Diabetic patients with IgA nephropathy and diabetic glomerulosclerosis

Eleven diabetic patients with biopsy-proven IgA nephropathy were studied. Seven exhibited coexistence of both IgA nephropathy and diabetic glomerulosclerosis and the remaining four patients had IgA nephropathy without diabetic lesion. The clinicopathological features and follow-up of those patients with IgA nephropathy surperimposed on diabetic glomerulosclerosis were compared with a similar group of patients with diabetic glomerulosclerosis alone. Our observation suggests that the occurrence of both glomerulopathies was fortuitous with IgA nephropathy coexisting with or preceding diabetic glomerulosclerosis. There was no apparent causal relationship between the two glomerulopathies. The renal outcome is poor in both groups of patients and is possibly related to diabetic glomerulosclerosis.

Crescentic glomerulonephritis related to hepatitis B virus

Crescentic glomerulonephritis was diagnosed in two chronic hepatitis B surface antigen carriers. In all three biopsies performed, hepatitis B e antigen was found in glomerular capillary tufts. The first patient presented with nephrotic syndrome and acute renal failure. The glomerular pathology revealed crescentic glomerulonephritis with endocapillary proliferation, and she recovered spontaneously with normal renal function over the following 6 mo despite a persistent hepatitis B surface antigenemia. The other patient presented with nephrotic syndrome and normal renal function. Hepatitis B virus-related membranous nephropathy was diagnosed on the first biopsy, and he did well on symptomatic treatment for 20 mo. The nephrotic syndrome recurred and subsequently he developed acute renal failure a month following interferon treatment. The repeated biopsy revealed a crescentic glomerulonephritis that was associated with mixed membranous and membranoproliferative glomerulopathies. This patient responded to immunosuppression and plasma exchange with residual impairment of renal function. He has been stable after 18 mo follow-up.

Endoscopic assessment of mucosal hemodynamic changes in a canine model of gastric ulcer

In studying the side effects of sclerosants injected into the gastric submucosa in dogs (N = 7), we noted that 3 ml of absolute ethanol induced a large gastric ulceration. We describe the time course of change in the ulcer size, and suggest that such ulceration can be used for the endoscopic assessment of factors important in ulcer genesis and healing. Endoscopic reflectance spectrophotometric measurement of indices of mucosal hemoglobin concentration (IHB) and oxygen saturation (ISO2) were performed in a separate group of dogs (N = 4) with ethanol-induced gastric ulceration. We found a significant difference (p less than 0.05) in IHB and ISO2 immediately before (97 +/- 8 and 37 +/- 3, respectively) and after (138 +/- 7 and 21 +/- 5, respectively) the ethanol injection. At 24 hours after the ethanol injection, the IHB at the lesion margin (141 +/- 14) was significantly higher (p less than 0.05) than that at the adjacent mucosa (101 +/- 4), whereas the ISO2 measurements were not significantly different in these two locations, 34 +/- 2 and 31 +/- 2, respectively. We conclude that (1) injection of 3 mol of absolute ethanol into the submucosa of the canine stomach provides an animal model of gastric ulceration in which the ulcer can be examined repeatedly with the aid of the endoscope; (2) in this ulcer model, ischemia with congestion (increases IHB, decreases ISO2) precedes the development of gross mucosal ulcerations; and (3) the margin of the established ulceration in this model exhibits hyperemia (increases IHB, normal ISO2) which mimics that of a healing gastric ulcer.

Multifocal leiomyosarcoma of the small intestine in childhood

We recently observed a 4-year-old Chinese boy with multifocal leiomyosarcoma of the small intestine with evidence of dissemination. Complete surgical excision was not possible and the response to postoperative chemotherapy was poor. The patient died 3 months after diagnosis. The prognosis for disseminated intestinal leiomyosarcoma in childhood appears to be poor.
