BACKGROUND
Current literature extensively covers the use of sphenopalatine ganglion stimulation (SPGs) in treating a broad spectrum of medical conditions, such as allergic rhinitis, cluster headaches, and strokes. Nevertheless, a discernible gap in the systematic organization and analysis of these studies is evident. This paper aims to bridge this gap by conducting a comprehensive review and analysis of existing literature on SPGs across various medical conditions.
METHODS
This study meticulously constructed a comprehensive database through systematic computerized searches conducted on PubMed, Embase, CNKI, Wanfang, VIP, and CBM up to May 2022. The inclusion criteria encompassed randomized controlled trials (RCTs) published in either Chinese or English, focusing on the therapeutic applications of SPGs for various medical conditions. Both qualitative and quantitative outcome indicators were considered eligible for inclusion.
RESULTS
This comprehensive study reviewed 36 publications, comprising 10 high-quality, 23 medium-quality, and three low-quality articles. The study investigated various diseases, including allergic rhinitis (AR), ischemic strokes (IS), cluster headache (CH), primary trigeminal neuralgia (PTN), pediatric chronic secretory otitis (PCSO), refractory facial paralysis (RFP), chronic tension-type headache (CTTH), as well as the analysis of low-frequency sphenopalatine ganglion stimulation (LF-SPGs) in chronic cluster headache (CCH) and the impact of SPGs on Normal nasal cavity function (NNCF). SPGs demonstrate efficacy in the treatment of AR. Regarding the improvement of rhinoconjunctivitis quality of life questionnaire (RQLQ) scores, SPGs are considered the optimal intervention according to the SUCRA ranking. Concerning the improvement in Total Nasal Symptom Score (TNSS), Conventional Acupuncture Combined with Tradiational Chinese Medicine (CA-TCM) holds a significant advantage in the SUCRA ranking and is deemed the best intervention. In terms of increasing Effective Rate (ER), SPGs outperformed both conventional acupuncture (CA) and Western Medicine (WM; < 0.05). In the context of SPGs treatment for IS, the results indicate a significant improvement in the 3-month outcomes, as evaluated by the modified Rankin Scale (mRS) in the context of Cerebral Cortical Infarction (CCI; < 0.05). In the treatment of CH with SPGs, the treatment has been shown to have a statistically significant effect on the relief and disappearance of headaches ( < 0.05). The impact of SPGs on NNCF reveals statistically significant improvements ( < 0.05) in nasal airway resistance (NAR), nasal cavity volume (NCV), exhaled nitric oxide (eNO), substance P (SP), vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY). SPGs treatments for PCSO, RFP, and CTTH, when compared to control groups, yielded statistically significant results ( < 0.05).
CONCLUSION
SPGs demonstrate significant effectiveness in the treatment of AR, IS, and CH. Effective management of CCH may require addressing both autonomic dysregulation and deeper neural pathways. However, additional high-quality research is essential to clarify its effects on NNCF, PTN, PCSO, RFP, and CTTH.

Thin endometrium (TE) is defined as a mid-luteal endometrial thickness ≤7mm. TE can affect endometrial tolerance, leading to lower embryo implantation rates and clinical pregnancy rates, and is also associated with impaired outcomes from assisted reproductive treatment. Herein, we systematically review TE causes, mechanisms, and treatments. TE pathogenesis has multiple causes, with the endometrium becoming thinner with age under hormonal influence. In addition, uterine cavity factors are important, as the inflammatory environment may affect expressions of certain genes thereby inhibiting endometrial stromal cell proliferation and promoting apoptosis. Long-term oral contraceptive use or the use of ovulation-promoting drugs are also definite factors contributing to endometrial thinning. Other patients have primary factors, for which the clinical etiology remains unknown. The main therapeutic strategies available for TE are pharmacological (including hormonal and vasoactive drugs), regenerative medicine, intrauterine infusion of growth factor-granulocyte colony-stimulating factor, autologous platelet-rich plasma, and complementary alternative therapies (including traditional Chinese herbal medicine and acupuncture). However, the associated mechanisms of action are currently unclear. Clinical scholars have proposed various approaches to improve treatment outcomes in patients with TE, and are exploring the principles of efficacy, offering potentials for novel treatments. It is hoped that this will improve TE tolerance, increase embryo implantation rates, and help more couples with infertility with effective treatments.

BACKGROUND
Methylene blue is an interesting approach in reducing fluid overload and vasoactive drug administration in vasodilatory shock. The inhibition of guanylate cyclase induced by methylene blue infusion reduces nitric oxide production and improves vasoconstriction. This systematic review and meta-analysis aimed to assess the effects of methylene blue administration compared to placebo on the hemodynamic status and clinical outcomes in patients with sepsis and septic shock.
METHODS
The authors specifically included randomized controlled trials that compared the use of methylene blue with placebo in adult patients with sepsis and septic shock. The outcomes were length of intensive care unit stay, hemodynamic parameters [vasopressor use], and days on mechanical ventilation. We also evaluated the abnormal levels of methemoglobinemia. This systematic review and meta-analysis were recorded in PROSPERO with the ID CRD42023423470.
RESULTS
During the initial search, a total of 1,014 records were identified, out of which 393 were duplicates. Fourteen citations were selected for detailed reading, and three were selected for inclusion. The studies enrolled 141 patients, with 70 of them in the methylene blue group and 71 of them in the control group. Methylene blue treatment was associated with a lower length of intensive care unit stay (MD -1.58; 95%CI -2.97, -0.20; = 25%; = 0.03), decreased days on mechanical ventilation (MD -0.72; 95%CI -1.26, -0.17; = 0%; = 0.010), and a shorter time to vasopressor discontinuation (MD -31.49; 95%CI -46.02, -16.96; = 0%; < 0.0001). No association was found with methemoglobinemia.
CONCLUSION
Administering methylene blue to patients with sepsis and septic shock leads to reduced time to vasopressor discontinuation, length of intensive care unit stay, and days on mechanical ventilation.

OBJECTIVES
Vasoactive drugs have exhibited clinical efficacy in addressing pulmonary arterial hypertension, manifesting a significant reduction in morbidity and mortality. Pulmonary hypertension may complicate advanced interstitial lung disease (PH-ILD) and is associated with high rates of disability, hospitalisation due to cardiac and respiratory illnesses, and mortality. Prior management hinged on treating the underlying lung disease and comorbidities. However, the INCREASE trial of inhaled treprostinil in PH-ILD has demonstrated that PH-ILD can be effectively treated with vasoactive drugs.
METHODS
This comprehensive systematic review examines the evidence for vasoactive drugs in the management of PH-ILD.
RESULTS
A total of 1442 pubblications were screened, 11 RCTs were considered for quantitative synthesis. Unfortunately, the salient studies are limited by population heterogeneity, short-term follow-up and the selection of outcomes with uncertain clinical significance.
CONCLUSIONS
This systematic review underscores the necessity of establishing a precision medicine-oriented strategy, directed at uncovering and addressing the intricate cellular and molecular mechanisms that underlie the pathophysiology of PH-ILD.

Review
Comparative efficacy of Chinese herbal injections in patients with cardiogenic shock (CS): a systematic review and Bayesian network meta-analysis of randomized controlled trials.
Cardiogenic shock (CS) is the primary cause of death in patients suffering acute myocardial infarction. As an emerging and efficacious therapeutic approach, Chinese herbal injections (CHIs) are gaining significant popularity in China. However, the optimal CHIs for treating CS remain uncertain. We searched eight databases from inception to 30 September 2023. Subsequently, we conducted the Bayesian network meta-analysis (NMA). Interventions were ranked based on the surface under the cumulative ranking curve (SUCRA) probability values. To compare the effects of CHIs on two distinct outcomes, a clustering analysis was performed. Furthermore, the quality of the studies was assessed. For the study, we included 43 RCTs, encompassing 2,707 participants. The study evaluated six herbal injections, namely, Shenfu injection (SF), Shengmai injection (SM), Shenmai injection (Sm), Danshen injection (DS), Huangqi injection (HQ), and Xinmailong injection (XML). The analysis findings suggested that Sm (MD = -1.05, 95% CI: -2.10, -0.09) and SF (MD = -0.81, 95% CI: -1.40, -0.25) showed better efficacy compared to Western medicine (WM) alone in reducing in-hospital mortality. The SUCRA values revealed that Sm + WM ranked first in terms of in-hospital mortality, cardiac index (CI), and hourly urine output but second in improving left ventricular ejection fraction (LVEF) and mean arterial pressure (MAP). SF + WM, however, had the greatest impact on raising the clinical effective rate. In MAP, SM + WM came out on top. Moreover, in terms of safety, only 14 studies (31.8%), including five types of CHIs: SF, Sm, SM, HQ, and XML, observed adverse drug reactions. To summarize, this analysis discovered that, in terms of patients suffering from CS, CHIs + WM yielded significantly greater advantages than WM alone. Based on in-hospital mortality and the remaining outcomes, Sm performed excellently among all the involved CHIs. : https:// www.Crd.york.ac.uk/prospero/, identifier: CRD42022347053.

Meta-Analysis Review
BACKGROUND
The objective of this study is to conduct a systematic review and meta-analysis examining the relationship between the vasoactive-inotropic score (VIS) and patient outcomes in surgical settings.
METHODS
Two independent reviewers searched PubMed, Web of Science, EMBASE, Scopus, Cochrane Library, Google Scholar, and CNKI databases from November 2010, when the VIS was first published, to December 2022. Additional studies were identified through hand-searching the reference lists of included studies. Eligible studies were those published in English that evaluated the association between the VIS and short- or long-term patient outcomes in both pediatric and adult surgical patients. Meta-analysis was performed using RevMan Manager version 5.3, and quality assessment followed the Joanna Briggs Institute (JBI) Critical Appraisal Checklists.
RESULTS
A total of 58 studies comprising 29,920 patients were included in the systematic review, 34 of which were eligible for meta-analysis. Early postoperative VIS was found to be associated with prolonged mechanical ventilation (OR 5.20, 95% CI 3.78-7.16), mortality (OR 1.08, 95% CI 1.05-1.12), acute kidney injury (AKI) (OR 1.26, 95% CI 1.13-1.41), poor outcomes (OR 1.02, 95% CI 1.01-1.04), and length of stay (LOS) in the ICU (OR 3.50, 95% CI 2.25-5.44). The optimal cutoff value for the VIS as an outcome predictor varied between studies, ranging from 10 to 30.
CONCLUSION
Elevated early postoperative VIS is associated with various adverse outcomes, including acute kidney injury (AKI), mechanical ventilation duration, mortality, poor outcomes, and length of stay (LOS) in the ICU. Monitoring the VIS upon return to the Intensive Care Unit (ICU) could assist medical teams in risk stratification, targeted interventions, and parent counseling.

Review
BACKGROUND
Acetazolamide is a non-competitive inhibitor of carbonic anhydrase, an enzyme expressed in different cells of the central nervous system (CNS) and involved in the regulation of cerebral blood flow (CBF). The aim of this review was to understand the effects of acetazolamide on CBF, intracranial pressure (ICP) and brain tissue oxygenation (PbtO) after an acute brain injury (ABI).
METHODS
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA), we performed a comprehensive, computer-based, literature research on the PubMed platform to identify studies that have reported the effects on CBF, ICP, or PbtO of acetazolamide administered either for therapeutic or diagnostic purposes in patients with subarachnoid hemorrhage, intracerebral hemorrhage, traumatic brain injury, and hypoxic-ischemic encephalopathy.
RESULTS
From the initial search, 3430 records were identified and, through data selection, 11 of them were included for the qualitative analysis. No data on the effect of acetazolamide on ICP or PbtO were found. Cerebral vasomotor reactivity (VMR-i.e., the changing in vascular tone due to a vasoactive substance) to acetazolamide tends to change during the evolution of ABI, with the nadir occurring during the subacute stage. Moreover, VMR reduction was correlated with clinical outcome.
CONCLUSIONS
This systematic review showed that the available studies on the effects of acetazolamide on brain hemodynamics in patients with ABI are scarce. Further research is required to better understand the potential role of this drug in ABI patients.

Meta-Analysis
BACKGROUND
Severe community-acquired pneumonia (sCAP) is characterized by severe symptoms and a poor prognosis, especially with the recent global impact of novel coronavirus in recent years. The use of glucocorticoids in sCAP is currently a subject of debate. To evaluate the clinical efficacy and safety of glucocorticoids and provide guidance for their rational use in clinical practice, we conducted this study.
METHODS
We searched PubMed, Web of Science, and China National Knowledge Infrastructure using the following search terms: "pneumonia", "pneumonias", "Pulmonary Inflammation", "Pulmonary Inflammations", "Lung Inflammation", and "Lung Inflammations". The primary outcomes included mortality and the length of hospital stay. The secondary outcomes included the duration of mechanical ventilation, duration of vasoactive drug use, gastrointestinal bleeding, and multiple infections. The Cochrane Collaboration was used to assess the risk of bias of the included studies. Stata/MP14 was used for meta-analysis.
RESULTS
These studies contained information on 1252 patients who received glucocorticoids and 1280 patients who did not. Meta-analysis showed that there was no difference in terms of mortality [risk ratio (RR) = 0.93, 95% confidence interval (CI): 0.81-1.07, P > .05], gastrointestinal bleeding (RR = 1.38, 95% CI: 0.83-2.30, P < .05), multiple infections (RR = 1.17, 95% CI: 0.90-1.53, P > .05) and length of hospital stay (mean difference [MD] = -0.87, 95% CI: -2.35 to 0.61, P > .05) between the hormonal and nonhormonal groups. However, there was a significant difference in the duration of mechanical ventilation (MD = -1.54; 95% CI, -1.89 to -1.12, P < .05) and the duration of use of vasoactive drugs (MD = -14.09, 95% CI: -15.72 to -12.46, P < .05).
CONCLUSION
Glucocorticoids reduced the duration of mechanical ventilation duration and vasoactive drug use in sCAP patients without increasing the risk of adverse events including hyperglycemia and multiple infections. However, there was no significant difference in mortality or length of hospital stay in sCAP patients between glucocorticoid and non-glucocorticoid groups. Glucocorticoids could be recommended for patients with sCAP with respiratory failure or hemodynamic instability.

Alternative Therapies in Health and... Nov 2023This systematic review aimed to identify independent prognostic factors of severe pneumonia.
OBJECTIVES
This systematic review aimed to identify independent prognostic factors of severe pneumonia.
METHODS
A systematic search was undertaken in Pubmed, Embase, and Web of Science from inception to March 2023 to find cohort studies investigating the association between prognostic factors and adverse outcomes of severe pneumonia in adult patients. The study selection process involved screening the title and abstract of articles to identify relevant studies on severe pneumonia in adult patients. Inclusion criteria included studies with a prospective or retrospective longitudinal design, investigating prognostic factors, and performing multivariate analysis. Exclusion criteria included non-English or non-Chinese studies, studies focusing on severe pneumonia in children, studies conducting only univariate analysis, and conference abstracts, reviews, and case reports. The risk of bias was assessed by the Quality In Prognosis Studies (QUIPS) tool.
RESULTS
A total of 27 published studies, including both prospective and retrospective cohort studies, were included. These studies reported on 53 different prognostic factors and covered four unique outcomes. The quality assessment indicated that 59.3% of the studies had a low risk of bias. Age, functional dependence, heart rate, and oxygen saturation/respiratory rate index were found to be associated with mortality. Additionally, various laboratory indexes, such as serum cholinesterase, albumin, and blood urea nitrogen to creatinine ratio, demonstrated either protective or risk factors for prognosis. Injury and comorbidities, including acute renal failure, chronic lung disease, and Glasgow Coma Scale, were identified as risk factors for mortality. Scoring tools like Acute Physiological and Chronic Health Evaluation (APACHE) II score, CURB-65 score, and Pneumonia Severity Index (PSI) score showed associations with mortality. Lastly, certain treatment protocols, such as vasoactive agent use, vasopressor use, and mechanical ventilation, were found to increase the risk of mortality, while invasive mechanical ventilation and the use of remdesivir and steroids had a positive impact on prognosis. These findings provide valuable insights for clinicians in predicting and managing severe pneumonia outcomes.
CONCLUSION
This most comprehensive review identified 53 unique prognostic factors of severe pneumonia, which provided a reference for subsequent researchers to construct models to predict clinical outcomes in patients with severe pneumonia for clinical use. By identifying prognostic factors through multivariate analysis, healthcare providers can better assess the severity and prognosis of individual patients. This knowledge can aid in treatment planning, resource allocation, and determining the appropriate level of care for patients with severe pneumonia. Additionally, understanding the prognostic factors can help identify high-risk patients who may require more intensive monitoring or interventions. Overall, this study provides valuable insights that can inform clinical practice and improve patient outcomes in the management of severe pneumonia.
