Meta-Analysis Review
BACKGROUND
Pertussis, a highly contagious, vaccine-preventable respiratory infection caused by Bordetella pertussis, is a leading global public health issue. Ethiopia is currently conducting multiple pertussis outbreak investigations, but there is a lack of comprehensive information on attack rate, case fatality rate, and infection predictors. This study aimed to measure attack rates, case fatality rates, and factors associated with pertussis outbreak.
METHODS
This study conducted a systematic review and meta-analysis of published and unpublished studies on pertussis outbreaks in Ethiopia from 2009 to 2023, using observational study designs, using the guideline Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The study utilized databases like Science Direct, MEDLINE/PubMed, African Journals Online, Google Scholar and registers. The data were collected using an Excel Spreadsheet and then exported to STATA version 17 for analysis. Subgroup analysis was conducted to identify potential disparities. A random effects model was used to consider heterogeneity among studies. I-squared test statistics were used to assess heterogeneity. The attack rate, case fatality rate, and odds ratio (OR) were presented using forest plots with a 95% confidence interval. Egger's and Begg's tests were used to evaluate the publication bias.
RESULTS
Seven pertussis outbreak investigations with a total of 2824 cases and 18 deaths were incorporated. The pooled attack and case fatality rates were 10.78 (95% CI: 8.1-13.5) per 1000 population and 0.8% (95% CI: 0.01-1.58%), respectively. The highest and lowest attack rates were in Oromia (5.57 per 1000 population and in the Amhara region (2.61 per 1000 population), respectively. Predictor of pertussis outbreak were being unvaccinated [odds ratio (OR) = 3.05, 95% CI: 1.83-4.27] and contact history [OR = 3.44, 95% CI: 1.69-5.19].
CONCLUSION
Higher and notable variations in attack and case fatality rates were reported. Being unvaccinated and having contact history were the predictors of contracting pertussis disease in Ethiopia. Enhancing routine vaccination and contact tracing efforts should be strengthened.

Meta-Analysis
Exploration of quantitative-effectiveness association between acupuncture temporal parameters and stable chronic obstructive pulmonary disease: A systematic review and dose-response meta-analysis of randomized controlled trials.
INTRODUCTION
Chronic Obstructive Pulmonary Disease (COPD) is a globally common chronic respiratory disease with a high morbidity and mortality rate. Acupuncture has been proven effective for COPD. A dose-response meta-analysis was conducted to assess the correlation between the acupuncture temporal parameters(session, frequency, and duration) and its effectiveness in patients with stable COPD.
METHODS
Acupuncture randomized controlled trials on COPD were searched in eight databases from their inception to June 2023. The "doses" were defined as the acupuncture session, frequency, and duration. The outcomes mainly included Forced Expiratory Volume in one-second rate (FEV1%) and Six-minute Walking Distance (6MWD). The assessment of bias risk and literature quality were conducted independently using the Cochrane risk of bias tool and the Standards for reporting interventions in clinical trials of acupuncture. The dose-response relationship was modeled using robust error element regression, and meta-analysis was operated by R 4.3.1 and Stata 15.0. The protocol was registered in PROSPERO with the registration number CRD42023401406.
RESULT
Out of 1669 records, 17 RCTs with 1165 participants were finally included in the meta-analysis. There was notable heterogeneity among the studies, but sensitivity analysis demonstrated good robustness. The findings revealed a significant improvement in the following outcomes for stable COPD patients in the acupuncture group: FEV1% (MD=3.50, 95%CI: 2.05-4.95), 6MWD (MD=47.39, 95%CI: 29.29-65.50), St. George's respiratory questionnaire (SGRQ; MD=-8.25, 95%CI: -11.38 to -5.12); COPD assessment test (CAT; MD=-2.91, 95%CI: -3.99 to -1.83). The relationship between the acupuncture session, duration, and FEV1%, 6MWD followed a "Λ" curve pattern, while the relationship between acupuncture frequency and FEV1%, 6MWD exhibited logarithmic growth. Firstly, After 12 acupuncture sessions, FEV1% and 6MWD increased by 7.06% (95%CI: 4.56-9.55) and 36.28 m (95%CI: 20.37-52.20), respectively. The peak improvement in FEV1% and 6MWD was observed after 18 acupuncture sessions (MD=7.89, 95% CI: 5.33-10.45) and 45 sessions (MD=125.43, 95% CI: 72.80-178.07) each. Additionally, weekly acupuncture resulted in a 4.14% improvement in FEV1% (95% CI: 2.55-5.72) and a 42.49 m increase in 6MWD (95%CI: 17.16-67.81). Notably, the maximum effects on FEV1% and 6MWD improvement were achieved with different acupuncture frequencies, specifically three times a week (MD=6.00, 95% CI: 5.34-6.66) and once a day(MD=112.41, 95% CI: 77.27-147.56), respectively. Furthermore, after a 28-day duration of acupuncture treatment, FEV1% increased by 4.74% (95% CI: 3.73-5.75) and 6MWD increased by 47.34 m (95%CI: 22.01-72.67). During 60 days of acupuncture treatment, the FEV1% and 6MWD improvement reached their highest levels at 8.76% (95% CI: 7.05-10.47) and 88.06 m (95% CI: 45.96-130.16), respectively.
CONCLUSION
Acupuncture was effective in improving FEV1%, 6MWD, SGRQ, and CAT in patients with stable COPD. There was a dose-response relationship between the time parameters of acupuncture (session, frequency, and duration) and the efficacy of COPD treatment (FEV1% and 6MWD). The minimal clinically important difference could be achieved after 12 acupuncture sessions. Acupuncture with a medium-frequency (2-3 times per week) over 60 days may result in the greatest improvement in FEV1%, while higher-frequency acupuncture (5-7 times per week) for 2 months may lead to the maximum improvements in 6MWD. It indicated that the optimal acupuncture duration for different indicators remains consistent, while the optimal frequencies may differ. To confirm these results, it is necessary to conduct multicenter, large-scale randomized controlled trials.

Review
Early after the start of the COVID-19 pandemic, the detection of influenza B/Yamagata cases decreased globally. Given the potential public health implications of this decline, in this Review, we systematically analysed data on influenza B/Yamagata virus circulation (for 2020-23) from multiple complementary sources of information. We identified relevant articles published in PubMed and Embase, and data from the FluNet, Global Initiative on Sharing All Influenza Data, and GenBank databases, webpages of respiratory virus surveillance systems from countries worldwide, and the Global Influenza Hospital Surveillance Network. A progressive decline of influenza B/Yamagata detections was reported across all sources, in absolute terms (total number of cases), as positivity rate, and as a proportion of influenza B detections. Sporadically reported influenza B/Yamagata cases since March, 2020 were mostly vaccine-derived, attributed to data entry errors, or have yet to be definitively confirmed. The likelihood of extinction necessitates a rapid response in terms of reassessing the composition of influenza vaccines, enhanced surveillance for B/Yamagata, and a possible change in the biosafety level when handling B/Yamagata viruses in laboratories.

OBJECTIVE
The role of esketamine in pediatric gastrointestinal endoscopy is still unclear. This study aims to evaluate the efficacy and safety of esketamine for pediatric gastrointestinal endoscopy.
METHODS
Clinical trials of esketamine for pediatric gastrointestinal endoscopy were searched in eight common databases, up to October 2023. These clinical trials were included in the meta-analysis and trial sequential analysis (TSA). The risk ratio (RR) and weighted mean difference (WMD) were used as the effect sizes for dichotomous variables and continuity variables, respectively. When the heterogeneity test showed I < 50%, the fixed effects model was used for the meta-analysis and TSA; Otherwise, the random effects model was used for them.
RESULTS
In terms of efficacy endpoints, the meta-analysis showed that compared with placebo or blank, esketamine significantly decreased recovery time by 2.34 min (WMD -2.34; 95% Confidence interval [CI] -3.65, -1.02; = 0.0005) and propofol consumption by 0.70 mg/kg (WMD -0.70; 95% CI -0.98, -0.43; < 0.00001), and increased mean heart rate by 4.77 beats/min (WMD 4.77; 95% CI 2.67, 6.87; < 0.00001) and mean arterial pressure by 3.10 mmHg (WMD 3.10; 95% CI 1.52, 4.67; = 0.0001), while induction time and mean blood oxygen remained comparable. TSA indicated conclusive evidence for these benefits. In terms of safety endpoints, the meta-analysis revealed that esketamine significantly reduced involuntary movements by 59% (RR 0.41; 95% CI 0.22, 0.76; = 0.005) and choking by 51% (RR 0.49; 95% CI 0.26, 0.92; = 0.03), while significantly increasing dizziness by 98% (RR 1.98; 95% CI 1.11, 3.56; = 0.02) and there were no significant differences in total adverse events, respiratory depression, and vomiting. TSA demonstrated conclusive evidence for involuntary movements and dizziness. Low-dose analysis showed that esketamine at ≤0.3 mg/kg significantly reduced recovery time, propofol consumption and involuntary movements, and significantly increasing mean heart rate, with no increase in dizziness. The Begg's test ( = 0.327) and the Egger's test ( = 0.413) indicated no significant publication bias, yet the funnel plot suggested potential publication bias.
CONCLUSION
Esketamine is an effective adjuvant anesthesia for children undergoing gastrointestinal endoscopy. However, the general dose of esketamine may increase the risk of dizziness, which can be avoided by administering a low dose (≤0.3 mg/kg).

Meta-Analysis
INTRODUCTION
This meta-analysis sought to investigate the effect of neoadjuvant chemotherapy (NACT) combined with surgery in patients with nonsmall cell lung cancer (NSCLC).
METHODS
With time span from January 2010 to December 2022, PubMed, Web of Science and Embase, China National Knowledge Infrastructure, and WanFang databases were searched for randomized controlled trials on comparison between NACT combined with surgery and surgery alone in patients with NSCLC. Then a meta-analysis was performed in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
RESULTS
A total of 1511 studies were retrieved and 12 were finally included. Meta-analysis results showed that compared with surgery alone, a combination of NACT and surgery was associated with higher treatment response rate (odds ratio, OR = 2.459, 95% confidence interval, CI [1.785, 3.388], P < 0.001), 1-year survival rate (OR = 2.185, 95% CI [1.608, 2.970], P < 0.001), and 3-year survival rate (OR = 2.195, 95% CI [1.568, 3.073], P < 0.001) and lower levels of intraoperative blood loss (standardized mean difference, SMD = -0.932, 95% CI [-1.588, -0.275], P = 0.005) and length of hospital stay (SMD = -0.481, 95% CI [-0.933, -0.028], P = 0.037).
CONCLUSION
NACT combined with surgery is superior to surgery alone in the treatment of NSCLC and can promote postoperative recovery. Collectively, such combination is a safe and effective treatment for patients with NSCLC.

Review
BACKGROUND
The possibility of developing a severe coronavirus infectious (COVID-19) disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has increased, particularly in patients with hematological malignancies. These patients are more likely to produce less antibody protection due to the immunocompromised nature of the disease and the anticancer treatments. Therefore, the present systematic review intended to evaluate the seroconversion rate of COVID-19 vaccines in patients with hematological malignancies compared with healthy controls.
METHODS
A comprehensive systematic search was conducted in Medline via PubMed, EMBASE, and the World Health Organization COVID-19 Research Database, as well as other searches (i.e., reference list from article search and manual searches), from December 2020 to May 2022. The outcome of interest included estimating the seroconversion rates following COVID-19 vaccination in patients with hematological malignancies and comparing them with those in healthy controls. After two-step screening, the data were extracted and the summary measures were calculated using a random-effects model.
RESULTS
A total of 39 articles regarding patients with hematological malignancies were included in the present review. After the first vaccine dose, these patients had considerably lower antibody response rates (37.0%) compared with healthy controls (74.5%). Following the second vaccine dose, the seroconversion rate in patients reached 66.8%, whereas it peaked at 97.9% in the healthy controls following complete immunization. Notably, the BNT162b2 and ChAdOx1 vaccine combination achieved the highest seropositivity rate of approximately 70%. Multiple myeloma, chronic lymphocytic leukemia, and lymphoma were the cancers of interest in most of the studies.
CONCLUSIONS
The results of the present study highlighted the comparatively low seropositivity rates in patients with hematological malignancies, with substantial variations in rates across disease groups. The findings emphasize the possibility of additional booster doses for these individuals to enhance their immunity against SARS-CoV-2.

Meta-Analysis
BACKGROUND
Re-intubation secondary to post-extubation respiratory failure in post-operative patients is associated with increased patient morbidity and mortality. Non-invasive respiratory support (NRS) alternative to conventional oxygen therapy (COT), i.e., high-flow nasal oxygen, continuous positive airway pressure, and non-invasive ventilation (NIV), has been proposed to prevent or treat post-extubation respiratory failure. Aim of the present study is assessing the effects of NRS application, compared to COT, on the re-intubation rate (primary outcome), and time to re-intubation, incidence of nosocomial pneumonia, patient discomfort, intensive care unit (ICU) and hospital length of stay, and mortality (secondary outcomes) in adult patients extubated after surgery.
METHODS
A systematic review and network meta-analysis of randomized and non-randomized controlled trials. A search from Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials, and Web of Science from inception until February 2, 2024 was performed.
RESULTS
Thirty-three studies (11,292 patients) were included. Among all NRS modalities, only NIV reduced the re-intubation rate, compared to COT (odds ratio 0.49, 95% confidence interval 0.28; 0.87, p = 0.015, I = 60.5%, low certainty of evidence). In particular, this effect was observed in patients receiving NIV for treatment, while not for prevention, of post-extubation respiratory failure, and in patients at high, while not low, risk of post-extubation respiratory failure. NIV reduced the rate of nosocomial pneumonia, ICU length of stay, and ICU, hospital, and long-term mortality, while not worsening patient discomfort.
CONCLUSIONS
In post-operative patients receiving NRS after extubation, NIV reduced the rate of re-intubation, compared to COT, when used for treatment of post-extubation respiratory failure and in patients at high risk of post-extubation respiratory failure.

INTRODUCTION
It is essential to link the theoretical framework of any neurophysiotherapy approach with a detailed analysis of the central motor control mechanisms that influence motor behavior. Vojta therapy (VT) falls within interventions aiming to modify neuronal activity. Although it is often mistakenly perceived as exclusively pediatric, its utility spans various functional disorders by acting on central pattern modulation. This study aims to review the existing evidence on the effectiveness of VT across a wide range of conditions, both in the adult population and in pediatrics, and analyze common therapeutic mechanisms, focusing on motor control modulation.
AIM
The goals of this systematic review are to delineate the existing body of evidence concerning the efficacy of Vojta therapy (VT) in treating a broad range of conditions, as well as understand the common therapeutic mechanisms underlying VT with a specific focus on the neuromodulation of motor control parameters.
METHODS
PubMed, Cochrane Library, SCOPUS, Web of Science, and Embase databases were searched for eligible studies. The methodological quality of the studies was assessed using the PEDro list and the Risk-Of-Bias Tool to assess the risk of bias in randomized trials. Methodological quality was evaluated using the Risk-Of-Bias Tool for randomized trials. Random-effects meta-analyses with 95% CI were used to quantify the change scores between the VT and control groups. The certainty of our findings (the closeness of the estimated effect to the true effect) was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE).
RESULTS
Fifty-five studies were included in the qualitative analysis and 18 in the meta-analysis. Significant differences in cortical activity ( = 0.0001) and muscle activity ( = 0.001) were observed in adults undergoing VT compared to the control, as well as in balance in those living with multiple sclerosis ( < 0.03). Non-significant differences were found in the meta-analysis when evaluating gross motor function, oxygen saturation, respiratory rate, height, and head circumference in pediatrics.
CONCLUSION
Although current evidence supporting VT is limited in quality, there are indications suggesting its potential usefulness for the treatment of respiratory, neurological, and orthopedic pathology. This systematic review and meta-analysis show the robustness of the neurophysiological mechanisms of VT, and that it could be an effective tool for the treatment of balance in adult neurological pathology. Neuromodulation of motor control areas has been confirmed by research focusing on the neurophysiological mechanisms underlying the therapeutic efficacy of VT.https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=476848, CRD42023476848.

Meta-Analysis Review
Immunologic responses to the third and fourth doses of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in cell therapy recipients: a systematic review and meta-analysis.
BACKGROUND
Multiple studies have provided evidence of suboptimal or poor immune responses to SARS-CoV-2 vaccines in recipients of hematopoietic stem cell transplantation (HSCT) and chimeric antigen receptor-T (CAR-T) cell therapy compared to healthy individuals. Given the dynamic nature of SARS-CoV2, characterized by the emergence of many viral variations throughout the general population, there is ongoing discussion regarding the optimal quantity and frequency of additional doses required to sustain protection against SARS-CoV2 especially in this susceptible population. This systematic review and meta-analysis investigated the immune responses of HSCT and CAR-T cell therapy recipients to additional doses of the SARS-CoV-2 vaccines.
METHODS
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the study involved a comprehensive search across PubMed, Scopus, Web of Science Core Collection, Embase, and Cochrane Biorxiv and medRxiv, focusing on the serological responses to the third and fourth vaccine doses in HSCT and CAR-T cell patients.
RESULTS
This study included 32 papers, with 31 qualifying for the meta-analysis. Results showed that after the third dose, the seroconversion rate in HSCT and CAR-T cell therapy recipients who didn't respond to the second dose was 46.10 and 17.26%, respectively. Following the fourth dose, HSCT patients had a seroconversion rate of 27.23%. Moreover, post-third-dose seropositivity rates were 87.14% for HSCT and 32.96% for CAR-T cell therapy recipients. Additionally, the seropositive response to the fourth dose in the HSCT group was 90.04%.
CONCLUSION
While a significant portion of HSCT recipients developed antibodies after additional vaccinations, only a minority of CAR-T cell therapy patients showed a similar response. This suggests that alternative vaccination strategies are needed to protect these vulnerable groups effectively. Moreover, few studies have reported cellular responses to additional SARS-CoV-2 vaccinations in these patients. Further studies evaluating cellular responses are required to determine a more precise assessment of immunogenicity strength against SARS-CoV-2 after additional doses.

Meta-Analysis
PURPOSE
A systematic review and meta-analysis to evaluate the impact of extracorporeal carbon dioxide removal (ECCOR) on gas exchange and respiratory settings in critically ill adults with respiratory failure.
METHODS
We conducted a comprehensive database search, including observational studies and randomized controlled trials (RCTs) from January 2000 to March 2022, targeting adult ICU patients undergoing ECCOR. Primary outcomes were changes in gas exchange and ventilator settings 24 h after ECCOR initiation, estimated as mean of differences, or proportions for adverse events (AEs); with subgroup analyses for disease indication and technology. Across RCTs, we assessed mortality, length of stay, ventilation days, and AEs as mean differences or odds ratios.
RESULTS
A total of 49 studies encompassing 1672 patients were included. ECCOR was associated with a significant decrease in PaCO, plateau pressure, and tidal volume and an increase in pH across all patient groups, at an overall 19% adverse event rate. In ARDS and lung transplant patients, the PaO/FiO ratio increased significantly while ventilator settings were variable. "Higher extraction" systems reduced PaCO and respiratory rate more efficiently. The three available RCTs did not demonstrate an effect on mortality, but a significantly longer ICU and hospital stay associated with ECCOR.
CONCLUSIONS
ECCOR effectively reduces PaCO and acidosis allowing for less invasive ventilation. "Higher extraction" systems may be more efficient to achieve this goal. However, as RCTs have not shown a mortality benefit but increase AEs, ECCOR's effects on clinical outcome remain unclear. Future studies should target patient groups that may benefit from ECCOR.
