Meta-Analysis
BACKGROUND
Subacute thyroiditis (SAT) is a self-limited inflammatory thyroid disease with recurring episodes. However, the results regarding the recurrence rate and risk factors for SAT are inconsistent. This meta-analysis aimed to summarize the evidence of the recurrence rate and the risk factors for SAT.
METHODS
The present study involved the performance of a systematic literature search of all English studies published in PubMed, Embase, Web of Science, and The Cochrane Library from inception to August 20, 2021. Cohort studies that reported the SAT recurrence rate and risk factors for recurrence were included. Two independent investigators extracted relevant information. Fixed- and random-effects models were used to pool effect sizes based on study heterogeneity.
RESULTS
Eighteen cohort studies were identified. The pooled findings showed that the recurrence rate was 12.0% (95% CI: 8.2%, 17.1%). The risk of recurrence in the glucocorticoids group was higher than that in the NSAIDs group (RR = 1.84, 95% CI: 1.04, 3.24). However, there was no significant difference in age or sex between the recurrence group and the non-recurrence group. Findings from one or two cohort studies also indicated that the copresence of and , the number of days required to taper prednisolone (PSL) to 5 mg/day, the duration of disease before treatment less than 30 days, the sialic acid level, or the TSH level at the termination of treatment and further extension of the hypoechoic area and increase in thyroid volume were related to the recurrence of SAT.
CONCLUSION
Recurrence was common in SAT patients. The present study indicated that glucocorticoid treatment was associated with a higher recurrence rate of SAT than NSAIDs treatment. The clinical implications of this association should be interpreted with caution, and further clinical trials on the long-term effects of different treatment strategies are needed.

BACKGROUND
Hormonal drug therapy has been widely used in clinical practice for the treatment of progressive muscular dystrophy (PMD). Glucocorticoids, as a common drug in the clinical treatment of PMD, have been reported in several clinical studies.
METHODS
Chinese and English databases were respectively searched using "randomized controlled trials", "Duchenne-type myotonic dystrophy", "glucocorticoids", Prednisone", "Prednisolone", and "Methylprednisolone", and "Defibrotide" were used as search terms. The meta-analysis was performed using the RevMan 5.3 and Stata 13 software provided by the Cochrane system.
RESULTS
this study included five randomized controlled trials, all of which described the correct randomization method. There were four detailed descriptions of hidden distribution schemes. There were four literatures using blind method. Heterogeneity analysis showed that there was some heterogeneity between the results of the mean prognostic muscle strength, walking time of 9 meters, and 4 flights of stairs climbing between the glucocorticoid-treated group (the experimental group) and the placebo group (the control group). There were no significant differences between the experimental group and the control group in average muscle strength level, walking time of 9 meters and climbing time of 4 flights of stairs (MD =1.77; 95% CI: -0.95 to 4.48; P=0.20>0.05), (MD =-12.27; 95% CI: -35.94 to 11.40; P=0.31>0.01), (MD =-3.09; 95% CI: -11.16 to 4.99; P=0.45>0.05). In addition, glucocorticoid treatment significantly increased creatine kinase level in patients with PMD (MD =-0.28, 95% CI: -0.57 to 0.00; P=0.05). In terms of the incidence of adverse reactions, glucocorticoid treatment significantly increased the prognostic probability of acne, rapid hair growth, and emotional irritability in PMD patients (OR =2.40; 95% CI: 1.09 to 5.27; P=0.03<0.05), (OR =3.05; 95% CI: 1.55 to 5.99; P=0.001<0.05), (OR =4.04; 95% CI: 1.82 to 10.63; P=0.001<0.05). There was no significant difference in the incidence of prognostic depression between the experimental group and the control group (OR =5.11; 95% CI: 0.80 to 32.79; P=0.09>0.05).
DISCUSSION
The results suggest that glucocorticoids have a significant effect on PMD patients, but to a certain extent they increase the incidence of adverse reactions in patients after treatment. However, due to the lack of complete clinical data in some ongoing studies, our conclusions may not be fully representative.

Review
Bullous pemphigoid (BP) is a widely recognized autoimmune blistering disease (AIBD) linked with a high incidence of morbidity and mortality. The aim of this study was to evaluate the available findings of randomized clinical trial studies to update interventions for Bullous pemphigoid. This article provides an updated overview of interventions for BP. A literature search was performed using Cochrane Central Register of Clinical Trials, MEDLINE, Scopus, and Web of Science from August 2010 to December 2020. All randomized clinical trials (RCTs) were done on adults and investigated the effectiveness of administered topical or systemic medications versus placebos or controls included in the current systematic review. Three RCTs comprising 363 patients were included in the systematic review. One of the eligible studies was placebo-controlled. All of the included studies used various interventions including, methylprednisolone plus azathioprine versus methylprednisolone plus dapsone, doxycycline versus prednisolone, and intravenous immunoglobulin (IVIG). Following their potentials in disease control, no difference was observed between dapsone and azathioprine; although, dapsone had a higher corticosteroid-sparing potential. The evaluation of the effect of doxycycline in short-term blister control in comparison to corticosteroids showed that the medication was not inferior to prednisolone, although it had a higher long-term safety. Therapeutic outcome of IVIG for steroid-resistant patients was satisfactory. Moreover, the effectiveness and reliability of various immunosuppressive drugs and tetracyclines are investigated by blinded RCTs for the treatment of BP.

Myasthenia gravis (MG) is an autoimmune condition affecting the neuromuscular junction characterised by weakness and fatiguability, carrying a high morbidity if treatment is delayed. A clear association with thymoma has led to management with thymectomy as a common practice, but MG presenting post-thymectomy has rarely been reported. We present a case of an 82- year-old woman developing fatigue, ptosis and dysarthria 3 months after thymectomy. After a clinical diagnosis of MG was made, she responded well to prompt treatment with prednisolone and pyridostigmine. Her anti-acetylcholine receptor antibody (anti-AChR) subsequently came back positive. Our systematic review reveals that post-thymectomy MG can be categorised as early-onset or late-onset form with differing aetiology, and demonstrated correlation between preoperative anti-AChR titres and post-thymectomy MG. The postulated mechanisms for post-thymectomy MG centre around long-lasting peripheral autoantibodies. Clinicians should actively look for MG symptoms in thymoma patients and measure anti-AChR preoperatively to aid prognostication.

Meta-Analysis
PURPOSE
Although the most recent systematic review and meta-analyses on acute respiratory distress syndrome (ARDS) have shown that the use of steroids decreases mortality in adult patients, its benefits and risks may differ depending on the type and dosage of the steroid. Therefore, we conducted a network meta-analysis (NMA) to compare the differences in the efficacy among different doses and types of steroids.
METHODS
We searched MEDLINE, CENTRAL, ICHUSHI, ClinicalTrials.gov, and WHO ICTRP databases from the earliest records to March 2021 for randomized control trials, which compared steroids with placebo or conventional therapy for ARDS. Using the random-effects model, we compared various categories of steroids (high-dose methylprednisolone, low-dose methylprednisolone, hydrocortisone, dexamethasone, and no steroid) concerning hospital mortality, incidence of infection, and ventilator-free days (VFD).
RESULTS
We analyzed nine studies involving adult patients (n = 1212). Although there were no significant differences between the groups in terms of the mortality and incidence of infection, the number of VFD were greater when using low-dose methylprednisolone than when not using any steroids (Mean difference: 6.06; 95% confidence intervals: [2.5, 10.5]). Moreover, the rank probability showed that low-dose methylprednisolone might be the optimal treatment, whereas using no steroid or high-dose methylprednisolone may be inferior to other treatments in terms of mortality, infection, and VFD.
CONCLUSION
This NMA suggested that the effect of steroids on the outcome in patients with ARDS might depend on the type of the steroid drug administered. Moreover, further studies are needed to identify the optimal type and dosage.

Neuromuscular Complications of Targeted Anticancer Agents: Can Tyrosine Kinase Inhibitors Induce Myasthenia Gravis? Getting Answers From a Case Report up to a Systematic Review.
More than 40 tyrosine kinase inhibitors (TKIs) have received hematological or oncological indications over the past 20 years, following the approval of imatinib, and many others are currently being tested in clinical and preclinical level. Beyond their common toxicities, no certain agent from this large class of molecularly targeted therapies was strongly associated with "off-target" impairment of neuromuscular transmission, and although myasthenia gravis (MG) is a well-characterized autoimmune disorder, only few sporadic events proven by serologically detected causative autoantibodies and/or by positive electrophysiological tests are reported in the literature. Herein, we present the first case of anti-MUSK (+) MG in a woman with metastatic BRAF-mutant melanoma after long-term treatment with dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor). Triggered by this report, a systematic literature review was conducted, summarizing all other cancer cases that developed MG, after exposure to any type of targeted agent and regardless of the underlying malignancy. All available data on the clinical diagnosis, the potential of administered TKIs to induce a seropositive myasthenic syndrome, the immune and non-immune-mediated pathogenesis of postsynaptic damage, and the challenging management of this neuromuscular toxicity were collected and discussed. In the presented case, MG was confirmed by both autoantibodies and nerve-conduction tests, while its reactivation after TKIs rechallenge supports a more than coincidental association. The following review identified 12 cancer cases with TKI-related MG in six case reports and one case series. In most of them, the myasthenia diagnosis was challenging, since the clinical symptomatology of fatigable weakness was not corroborating with consistent laboratory and electrophysiological findings. In fact, anti-AchR titers were positive in five and anti-MuSK only in the abovementioned individual. The symptomatology corresponded to TKI discontinuation and standard treatment with pyridostigmine and prednisolone; intravenous immunoglobulin was added only in three, and two required mechanical ventilation. In an era where TKIs will be prescribed more frequently for various malignancies, even in combinations with immune-checkpoint inhibitors, this report synthesizes their risk for neuromuscular complications and increases the clinicians' awareness in order to extend the on-treatment and overall survival of TKI-treated cancer patients.

Asian Pacific Journal of Cancer... Oct 2021This systematic review aimed to determine the efficacy of ketoconazole in the treatment of metastatic castration-resistant prostate cancer (mCRPC).
OBJECTIVE
This systematic review aimed to determine the efficacy of ketoconazole in the treatment of metastatic castration-resistant prostate cancer (mCRPC).
MATERIALS AND METHODS
A literature search was performed on four databases of PubMed, Google Scholar, Cochrane Database of Systematic Reviews, and Directory of Open Access Journals (DOAJ). The initial search resulted in 602 articles, which were progressively eliminated based on duplication, irrelevancy, and unsuitable methodology. A total of seventeen articles were included in the final analysis, including four randomized controlled trials, nine retrospective cohorts, and four prospective cohorts, with a total population of 1,095 patients. A 200-400 mg, tid dose of ketoconazole was used in these studies along with corticoid replacement therapy with hydrocortisone, 20-30 mg in the morning and 10-20 mg in the evening, or prednisone, 5 mg, bid.
RESULTS
Based on our findings, 8 out of 17 studies reported PSA decrease of >50% in approximately half of the population, with a more significant PSA response at 400 mg ketoconazole dosage, and the average progression-free survival (PFS) of 2.6-14.5 months, or time to progression of 3.2-6.7 months.
CONCLUSION
Ketoconazole with corticosteroid could be an effective alternative for the treatment of mCRPC with a satisfactory PSA response and disease progression.

Meta-Analysis
BACKGROUND
Since the start of the coronavirus disease 2019 (COVID-19) pandemic, there is an urgent need for effective therapies for patients with COVID-19. In this study, we aimed to assess the therapeutic efficacy of glucocorticoids in severe COVID-19.
METHODS
A systematic literature search was performed across PubMed, Web of Science, EMBASE, and the Cochrane Library (up to June 26, 2021). The literature investigated the outcomes of interest were mortality and invasive mechanical ventilation.
RESULTS
The search identified 13 studies with 6612 confirmed severe COVID-19 patients. Our meta-analysis found that using glucocorticoids could significantly decrease COVID-19 mortality (hazard ratio (HR) 0.60, 95% confidence interval (CI) 0.45-0.79, P < .001), relative to non-use of glucocorticoids. Meanwhile, using glucocorticoids also could significantly decrease the risk of progression to invasive mechanical ventilation for severe COVID-19 patients (HR = 0.69, 95% CI 0.58-0.83, P < .001). Compared with using dexamethasone (HR = 0.68, 95% CI 0.50-0.92, P = .012), methylprednisolone use had a better therapeutic effect for reducing the mortality of patients (HR = 0.35, 95% CI 0.19-0.64, P = .001).
CONCLUSION
The result of this meta-analysis showed that using glucocorticoids could reduce mortality and risk of progression to invasive mechanical ventilation in severe COVID-19 patients.

Meta-Analysis Review
BACKGROUND
People with chronic obstructive pulmonary disease (COPD) show considerable variation in symptoms, limitations, and well-being; this often complicates medical care. A multi-disciplinary and multi-component programme that addresses different elements of care could improve quality of life (QoL) and exercise tolerance, while reducing the number of exacerbations.
OBJECTIVES
To compare the effectiveness of integrated disease management (IDM) programmes versus usual care for people with chronic obstructive pulmonary disease (COPD) in terms of health-related quality of life (QoL), exercise tolerance, and exacerbation-related outcomes.
SEARCH METHODS
We searched the Cochrane Airways Group Register of Trials, CENTRAL, MEDLINE, Embase, and CINAHL for potentially eligible studies. Searches were current as of September 2020.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared IDM programmes for COPD versus usual care were included. Interventions consisted of multi-disciplinary (two or more healthcare providers) and multi-treatment (two or more components) IDM programmes of at least three months' duration.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial quality and extracted data. If required, we contacted study authors to request additional data. We performed meta-analyses using random-effects modelling. We carried out sensitivity analyses for the quality of included studies and performed subgroup analyses based on setting, study design, dominant intervention components, and region.
MAIN RESULTS
Along with 26 studies included in the 2013 Cochrane Review, we added 26 studies for this update, resulting in 52 studies involving 21,086 participants for inclusion in the meta-analysis. Follow-up periods ranged between 3 and 48 months and were classified as short-term (up to 6 months), medium-term (6 to 15 months), and long-term (longer than 15 months) follow-up. Studies were conducted in 19 different countries. The mean age of included participants was 67 years, and 66% were male. Participants were treated in all types of healthcare settings, including primary (n =15), secondary (n = 22), and tertiary care (n = 5), and combined primary and secondary care (n = 10). Overall, the level of certainty of evidence was moderate to high. We found that IDM probably improves health-related QoL as measured by St. George's Respiratory Questionnaire (SGRQ) total score at medium-term follow-up (mean difference (MD) -3.89, 95% confidence interval (CI) -6.16 to -1.63; 18 RCTs, 4321 participants; moderate-certainty evidence). A comparable effect was observed at short-term follow-up (MD -3.78, 95% CI -6.29 to -1.28; 16 RCTs, 1788 participants). However, the common effect did not exceed the minimum clinically important difference (MCID) of 4 points. There was no significant difference between IDM and control for long-term follow-up and for generic QoL. IDM probably also leads to a large improvement in maximum and functional exercise capacity, as measured by six-minute walking distance (6MWD), at medium-term follow-up (MD 44.69, 95% CI 24.01 to 65.37; 13 studies, 2071 participants; moderate-certainty evidence). The effect exceeded the MCID of 35 metres and was even greater at short-term (MD 52.26, 95% CI 32.39 to 72.74; 17 RCTs, 1390 participants) and long-term (MD 48.83, 95% CI 16.37 to 80.49; 6 RCTs, 7288 participants) follow-up. The number of participants with respiratory-related admissions was reduced from 324 per 1000 participants in the control group to 235 per 1000 participants in the IDM group (odds ratio (OR) 0.64, 95% CI 0.50 to 0.81; 15 RCTs, median follow-up 12 months, 4207 participants; high-certainty evidence). Likewise, IDM probably results in a reduction in emergency department (ED) visits (OR 0.69, 95%CI 0.50 to 0.93; 9 RCTs, median follow-up 12 months, 8791 participants; moderate-certainty evidence), a slight reduction in all-cause hospital admissions (OR 0.75, 95%CI 0.57 to 0.98; 10 RCTs, median follow-up 12 months, 9030 participants; moderate-certainty evidence), and fewer hospital days per person admitted (MD -2.27, 95% CI -3.98 to -0.56; 14 RCTs, median follow-up 12 months, 3563 participants; moderate-certainty evidence). Statistically significant improvement was noted on the Medical Research Council (MRC) Dyspnoea Scale at short- and medium-term follow-up but not at long-term follow-up. No differences between groups were reported for mortality, courses of antibiotics/prednisolone, dyspnoea, and depression and anxiety scores. Subgroup analysis of dominant intervention components and regions of study suggested context- and intervention-specific effects. However, some subgroup analyses were marked by considerable heterogeneity or included few studies. These results should therefore be interpreted with caution.
AUTHORS' CONCLUSIONS
This review shows that IDM probably results in improvement in disease-specific QoL, exercise capacity, hospital admissions, and hospital days per person. Future research should evaluate which combination of IDM components and which intervention duration are most effective for IDM programmes, and should consider contextual determinants of implementation and treatment effect, including process-related outcomes, long-term follow-up, and cost-effectiveness analyses.

Acute disseminated encephalomyelitis (ADEM) has been reported after coronavirus disease 2019 (COVID-19). In this review, we systematically included worldwide reported cases on this association. We included 30 case reports (pediatric and adults) and explored epidemiological and clinical evidence. We described time to diagnosis, clinical, imaging, and laboratory features, response to treatment regimens, and differences regarding severity. Also, an original case report was presented. Neurologists must be alert to the occurrence of multifocal neurological symptoms with or without encephalopathy in patients recovered from COVID-19. Timely MRI studies should be performed to establish the diagnosis and to consider early corticosteroid-based treatment.
