BACKGROUND
Fatigue, as a complex, multidimensional symptom, is associated with many physical illnesses. C. A. Mey (PG) is an important herbal drug which has been used for benefiting Qi for thousand years. C. A. Mey and its compounds (PGC) possess various pharmacological activities, including anti-fatigue. Here, we conducted a systematic review of both randomized clinical trials (RCTs) and preclinical animal studies to investigate the efficacy and safety of PGC for fatigue.
METHODS
Electronic searches were performed in 7 databases from the time of each database's inception to August 2019. The methodological quality of RCTs was assessed using 7-item checklist recommended by Cochrane Collaboration or by the CAMARADES 10-item quality checklist. All the data were analyzed using Rev-Man 5.3 and Stata SE software.
RESULTS
Eight eligible RCTs and 30 animal studies were identified. The risk of bias scores in RCTs ranged from 4/7 to 7/7, and of animal studies varied from 4/10 to 7/10. Meta-analyses showed that PGC was superior to placebo according to their respective fatigue scales, heart rate recovery, and clinical effect (P < 0.05). There were a similar number of adverse effects between PGC and placebo group (P > 0.05). Meta-analyses showed that PGC can significantly decrease level of blood lactate, blood urea nitrogen, creatine kinase, malondialdehyde, and lactic dehydrogenase in serum, level of malondialdehyde in liver and level of gamma-aminobutyric acid, 5-hydroxytryptamine in brain tissue, and increase swimming time, level of glutathione peroxidase, glucose, superoxide dismutase in serum, level of glycogen and activity of superoxide dismutase, glutathione peroxidase, and catalase in skeletal muscle, level of hepatic glycogen in liver and level of dopamine, acetylcholine in brain tissue, compared with control (P < 0.05). Meta-analyses showed no significant difference in animal body weight between PGC and control (P > 0.05).
CONCLUSION
The present findings supported, to a certain degree, that PGC can be recommended for routine use in fatigue. The possible mechanism of PGC resists fatigue, mainly through antioxidant stress, regulating carbohydrate metabolism, delaying the accumulation of metabolites, promoting mitochondrial function, neuroprotection, antiapoptosis, and regulating neurotransmitter disorder in central nervous system.

BACKGROUND
This study aimed to analyze the extent of fatigue responses after female soccer matches and the ensuing recovery time course of performance, physiological, and perceptual responses.
METHODS
Three databases (PubMed, Web of Science, and SPORTDiscus) were searched in October 2020 and updated in November 2021. Studies were included when participants were female soccer players, regardless of their ability level. Further, the intervention was an official soccer match with performance, physiological, or perceptual parameters collected pre- and post-match (immediately, 12 h, 24 h, 48 h, or 72 h-post).
RESULTS
A total of 26 studies (n = 465 players) were included for meta-analysis. Most performance parameters showed some immediate post-match reduction (effect size [ES] = - 0.72 to - 1.80), apart from countermovement jump (CMJ; ES = - 0.04). Reduced CMJ performance occurred at 12 h (ES = - 0.38) and 24 h (ES = - 0.42) and sprint at 48 h post-match (ES = - 0.75). Inflammatory and immunological parameters responded acutely with moderate-to-large increases (ES = 0.58-2.75) immediately post-match. Creatine kinase and lactate dehydrogenase alterations persisted at 72 h post-match (ES = 3.79 and 7.46, respectively). Small-to-moderate effects were observed for increased cortisol (ES = 0.75) and reduced testosterone/cortisol ratio (ES = -0.47) immediately post-match, while negligible to small effects existed for testosterone (ES = 0.14) and estradiol (ES = 0.34). Large effects were observed for perceptual variables, with increased fatigue (ES = 1.79) and reduced vigor (ES = - 0.97) at 12 h post-match, while muscle soreness was increased immediately post (ES = 1.63) and at 24 h post-match (ES = 1.00).
CONCLUSIONS
Acute fatigue exists following female soccer matches, and the performance, physiological, and perceptual parameters showed distinctive recovery timelines. Importantly, physical performance was recovered at 72 h post-match, whereas muscle damage markers were still increased at this time point. These timelines should be considered when planning training and match schedules. However, some caution should be advised given the small number of studies available on this population.
REGISTRATION
The protocol for this systematic review was pre-registered on the International Prospective Register of Systematic Reviews (PROSPERO, Registration Number: CRD42021237857).

BACKGROUND AND AIMS
Abnormalities in hematological and biochemical markers are assumed to be associated with the progression of COVID-19 disease. This meta-analysis was performed to assess the consequences of abnormalities of biomarkers (D-dimers, C-reactive protein [CRP], serum ferritin, lactate dehydrogenase [LDH], random blood sugar [RBS], absolute neutrophil count [ANC], neutrophil to lymphocyte ratio (NLR), serum creatinine, and hemoglobin) in the Bangladeshi COVID-19 patients.
METHODS
The data of biomarker levels in Bangladeshi COVID-19 patients were gathered from five databases: PubMed, ScienceDirect, Web of Science, Google Scholar and Bangladesh Journals Online between January 2020 to March 2022. Review Manager 5.4 was used for the meta-analysis, and Egger's test and Begg-Mazumdar's rank correlation were used to investigate publication bias.
RESULTS
This study included 1542 patients with 567 severe and 975 nonsevere statuses. Based on the accumulated data synthesis, there is a strong correlation between disease severity and different biomarkers, including D-dimer, CRP, ferritin, LDH, RBS, NLR, and serum creatinine (MD = 1.16, = 0.0004; MD = 22.97, = 0.003; MD = 419.26, < 0.00001; MD = 118.37, = 0.004; MD = 1.96, = 0.02; MD = 1.26, = 0.02; and MD = 0.31, = 0.008, respectively). A significantly decreased correlation was observed for hemoglobin levels in severe COVID-19 patients (MD = -0.73, = 0.10).
CONCLUSION
The elevated biomarkers level was noticed in severe cases compared to nonsevere patients, revealing that D-dimer, CRP, ferritin, LDH, RBS, NLR, and serum creatinine are significantly correlated to COVID-19 severity. Only lower hemoglobin level was found to be associated with COVID-19 severity.

INTRODUCTION
Pegcetacoplan, a pegylated penta-decapeptide, targets complement C3 to control both intravascular and extravascular hemolysis. This systematic review aims to study the efficacy and safety of pegcetacoplan in paroxysmal nocturnal hemoglobinuria (PNH).
METHODS
We performed a comprehensive and systematic literature search for all studies on PubMed, Google Scholar, Cochrane Library, and clinicaltrials.gov. The studies were searched using keywords "paroxysmal nocturnal hemoglobinuria" or "PNH," "Pegcetacoplan" or "Empaveli." The primary outcomes included change in hemoglobin level, transfusion independence, absolute reticulocyte count, and lactate dehydrogenase (LDH) level after pegcetacoplan therapy. The safety outcomes included the proportion of deaths and adverse effects.
RESULTS
We included a total of three studies. The total number of patients with PNH was112. 59.83% were female. In the PADDOCK study and study by Hillmen et al., the average increase in hemoglobin was 3.68 g/L and 2.37 g/L, respectively. In the study by de Castro et al., the hemoglobin level increased from below the lower limit of normal and stayed in the normal range (11.1-15.9 g/L). Absolute reticulocyte count and LDH levels decreased in all patients receiving pegcetacoplan. In the study by de Castro et al., LDH level remained stable, and within <1.5× upper limit of normal, whereas in the study by Hillman, the mean change of LDH from baseline was -15 ± 43 U/L. Two of six, seven of 23, and seven of 41 patients reported adverse events in the study by de Castro et al., PADDOCK, and Hillmen et al., respectively.
CONCLUSION
Pegcetacoplan effectively improves hemoglobin level and transfusion requirements in patients with PNH, including those unresponsive to eculizumab.

Meta-Analysis Review
INTRODUCTION
Cancer cachexia is a clinical condition characterized by recognizable "sickness behaviors" accompanied by loss of lean body tissue. The Global Leadership on Malnutrition (GLIM) has proposed phenotypic (unintentional weight loss, low body mass index and low muscle mass) and aetiologic (reduced food intake and inflammation or disease burden) diagnostic criteria. Recent work has suggested serum lactate dehydrogenase (LDH) might represent a 3rd aetiologic criteria. Little is known of its relationship with GLIM. A systematic review and meta-analysis of their comparative prognostic value and association was performed.
METHODS
A search of electronic databases (PubMed, Medline, Ovid, Cochrane) up to February 2023 was used to identify studies that compared the prognostic value of LDH and components of the GLIM criteria in cancer. An analysis of the relationship between LDH and the components of GLIM was undertaken where this data was available. RevMan 5.4.1 was used to perform a meta-analysis for each diagnostic criteria that had 3 or more studies which reported hazard ratios with a 95 per cent confidence interval for overall survival (OS).
RESULTS
A total of 119 studies were reviewed. Advanced lung cancer was the most studied population. Included in the meta-analysis were 6 studies (n=2165) on LDH and weight loss, 17 studies (n=7540) on LDH and low BMI, 5 studies (n=758) on LDH and low muscle mass, 0 studies on LDH and food intake and 93 studies (n=32,190) on LDH and inflammation. There was a significant association between elevated serum LDH and each of low BMI (OR 1.39, 1.09 - 1.77; p=0.008), elevated NLR (OR 2.04, 1.57 - 2.65; p<0.00001) and elevated CRP (OR 2.58, 1.81 - 3.67; p<0.00001). There was no association between elevated serum LDH and low muscle mass. Only one study presented data on the association between LDH and unintentional weight loss. Elevated LDH showed a comparative OS (HR 1.86, 1.57 - 2.07; p<0.00001) to unintentional weight loss (HR 1.57, 1.23 - 1.99; p=0.0002) and had a similar OS (HR 2.00, 1.70 - 2.34; p<0.00001) to low BMI (HR 1.57, 1.29-2.90; p<0.0001). LDH also showed an OS (HR 2.25, 1.76 - 2.87; p<0.00001) congruous with low muscle mass (HR 1.93, 1.14 - 3.27; p=0.01) and again, LDH conferred as poor an OS (HR 1.77, 1.64-1.90; p<0.00001) as elevated NLR (HR 1.61, 1.48 - 1.77; p<0.00001) or CRP (HR 1.55, 1.43 - 1.69; p<0.00001).
CONCLUSION
Current literature suggests elevated serum LDH is associated with inflammation in cancer (an aetiologic GLIM criterion), however more work is required to establish the relationship between LDH and the phenotypic components of GLIM. Additionally, elevated serum LDH appears to be a comparative prognosticator of overall survival in cancer when compared to the GLIM criteria.

Meta-Analysis
BACKGROUND
The prognosis of head &neck cancer (HNC) depends on its early detection, diagnosis, and treatment, which has advocated a search for a simple, reliable, noninvasive, cost-effective tool to aid in the same. Salivary lactate dehydrogenase has gained interest in recent years, meeting the above requisite.
OBJECTIVES
To evaluate the levels of salivary lactate dehydrogenase in patients with oral potentially malignant disorders (OPMD), HNC, and in the healthy control group (CG); to find the correlation, grade-wise and genderwise difference between them; and to assess whether it can be used as a potent biomarker in OPMD and HNC.
MATERIALS AND METHODS
A comprehensive search of the specialized 14 databases and 4 institutional repositories was performed for including the studies evaluating salivary lactate dehydrogenase in OPMD and HNC patients either comparing or not comparing to the healthy control group in the systematic review process. The meta-analysis was performed with the eligible study data with the STATA version 16, 2019 software with 95% CI and p ≤ 0.05 in the random-effects model.
RESULTS
Twenty-eight studies of case-control, interventional, or uncontrolled non-randomized design evaluating salivary lactate dehydrogenase were included. A total of 2074 subjects were included, involving HNC, OPMD, and CG. The salivary lactate dehydrogenase levels were significantly higher in HNC than in CG & oral leukoplakia (OL) (p=0.00); in OL & oral submucous fibrosis (OSMF) than CG (p=0.00); and higher in HNC than OSMF, however not significant (p=0.49). Also, the salivary lactate dehydrogenase levels had no significant difference between males and females in CG, HNC, OL, and OSMF groups(p> 0.05).
DISCUSSION
It is evident that the epithelial transformations in the various OPMD and HNC, and the proceeding necrosis in the case of HNC, raises the LDH levels. It's also worth noting that when degenerative alterations continue, the SaLDH levels rise correspondingly, which are higher in HNC than in OPMD. Hence, it is essential to determine the cut-off values for SaLDH for establishing that the patient may have HNC or OPMD. It would be easy to follow-up frequently and perform investigations such as biopsy for the cases with high SaLDH levels, thereby aiding in the early detection and improving the prognosis of HNC. Moreover, the increased SaLDH levels were indicative of a lower degree of differentiation and an advanced disease leading to a poor prognosis. Salivary sample collection is less invasive, simple, and more acceptable to the patient; however, saliva collection is a time-consuming procedure as it is mostly collected by the passive spit method. Also, it is more feasible to repeat the SaLDH analysis during the follow-up, but the method has recently gained interest for over a decade.
CONCLUSION
Salivary lactate dehydrogenase can be a potential biomarker for the screening, early detection, and follow-up of OPMD or HNC being simple, noninvasive, cost-effective, and readily acceptable modality. However, more studies with new standardized protocols are recommended to determine the precise cut-off levels for HNC and OPMD.

Attenuating Muscle Damage Biomarkers and Muscle Soreness After an Exercise-Induced Muscle Damage with Branched-Chain Amino Acid (BCAA) Supplementation: A Systematic Review and Meta-analysis with Meta-regression.
BACKGROUND
Branched-chain amino acid (BCAA) supplementation is one of the most popular strategies used by the general population and athletes to reduce muscle soreness and accelerate the recovery process of muscle damage biomarkers after an intense exercise or training session.
OBJECTIVES
This systematic review and meta-analysis investigated the effects of BCAA supplementation on muscle damage biomarkers and muscle soreness after exercise-induced muscle damage (EIMD).
METHODS
The systematic literature search for randomized controlled trials was conducted using seven databases, up to September 13th, 2022. The eligibility criteria for selecting studies were as follows: studies performed on healthy active participants, using BCAA at least once, controlled with a placebo or control group, performing resistance or endurance exercises, and followed up at least once post-EIMD. The methodological quality of the studies was assessed using the "SIGN RCT checklist". Random-effects meta-analyses were processed to compute the standardized mean difference (Hedges' g). Meta-regression analyses were completed with daily and total dosage and supplementation as continuous moderator variables.
RESULTS
Of the 18 studies included in this meta-analysis, 13 were of high quality and five were of acceptable quality. Our results revealed BCAA supplementation elicits a significant effect on reducing creatine kinase (CK) levels immediately (g = - 0.44; p = 0.006) and 72 h (g = - 0.99; p = 0.002), but not 24 h, 48 h, and 96 h post-EIMD. Additionally, a significant effect on delayed onset of muscle soreness (DOMS) was identified at 24 h (g = - 1.34; p < 0.001), 48 h (g = - 1.75; p < 0.001), 72 h (g = - 1.82; p < 0.001), and 96 h (g = - 0.82; p = 0.008), but not immediately post-EIMD. No significant effect was found on lactate dehydrogenase (LDH) levels at any time point. Meta-regression indicated higher daily and total dosages of BCAA, and longer supplementation periods were related to the largest beneficial effects on CK (total dosage and supplementation period) at 48 h, and on DOMS at 24 h (only daily dosage).
CONCLUSION
The overall effects of BCAA supplementation could be considered useful for lowering CK and DOMS after EIMD, but not LDH. The longer supplementation period prior to the EIMD could be more effective for CK and DOMS reduction.

Review
Intravascular lymphoma (IVL) is an aggressive systemic large B-cell lymphoma that is a rare cause of stroke. The clinical characteristics of stroke associated with IVL remain underexplored, contributing to diagnostic complexities and a high mortality rate. This study endeavors to elucidate the salient clinical and investigative features of stroke linked to this condition. A systematic review was performed using the PubMed database from the incident to August 2023 including search categories for IVL and stroke. All studies, excluding review articles, were included in this study. There were 58 cases with a confirmed diagnosis of IVL associated with stroke, with a mean age of 62.9 ± 9.6 years (female 50%). Classical lateralizing stroke symptoms were noted in only 69% of cases. Other clinical syndromes included altered sensorium (31%), rapidly progressive cognitive impairment (23%), seizures (22%), and gait disturbances (19%). Common hematological abnormalities included elevated lactate dehydrogenase (LDH, 97%), erythrocyte sedimentation rate (ESR, 79%), C-reactive protein (CRP, 61%), interleukin-2, microglobulins, and cerebrospinal fluid (CSF) protein. CSF flow cytometry was not diagnostic, and cytology was mostly negative. The dynamic pattern for DWI/T2 lesions was predominant and primarily located in the subcortical regions. Diffuse background slowing (64%) was a major finding in the electroencephalogram. Seventy-one percent of cases died (n=45) mostly due to delayed diagnosis. Only 31% were treated with first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, prednisone) chemotherapy, among whom 25% died. This study suggests that IVL-associated strokes carry a high mortality rate, largely due to challenges in timely diagnosis and therapy. Unlike classical stroke syndrome, key indicators to aid in early diagnosis include a clinical syndrome of multiple non-lateralizing neurological symptoms, dynamic MRI DWI/T2-lesions primarily located in subcortical regions, elevated serum LDH, ESR, CRP, interleukins, microglobulin, CSF protein, and CSF polymerase chain reaction analysis, apart from tissue examination. Larger studies should be performed to establish diagnostic and predictive scores.

Pancreatic ductal adenocarcinoma (PDAC) leads to the majority of cancer-related deaths due to its morbidity with similar mortality. Lack of effective prognostic biomarkers are the main reason for belated post-operative intervention of recurrence which causes high mortality. Numerous systematic reviews and meta-analyses have explored the prognostic value of biomarkers in PDAC so far. In this article, we performed an umbrella review analyzing these studies to provide an overview of associations between prognostic biomarkers and PDAC survival outcome and synthesized these results to guide better clinical practice. Systematic reviews and meta-analyses investigating the associations between PDAC survival outcomes and prognostic biomarkers were acquired via the PubMed and Embase databases from inception till February 1, 2020. Associations supported by nominally statistically significant results were classified into strong, highly suggestive, suggestive, and weak based on several critical factors such as the statistical significance of summary estimates, the number of events, the estimate of the largest study included, interstudy heterogeneity, small-study effects, 95% predictive interval (PI), excess significance bias, and the results of credibility ceiling sensitivity analyses. We included 41 meta-analyses containing 63 associations between PDAC survival outcomes and prognostic biomarkers. Although, none was supported by strong evidence among these associations, an association between C-reactive protein to albumin ratio (CAR) and PDAC overall survival (OS) and an association between neutrophil-lymphocyte ratio (NLR) and PDAC OS were supported by highly suggestive evidence. Otherwise, the association between lactate dehydrogenase (LDH) and PDAC OS was supported by suggestive evidence. The remaining 60 associations were supported by weak or not suggestive evidence. Associations between CAR or NLR and PDAC OS were supported by highly suggestive evidence. And the association between LDH and PDAC OS was supported by suggestive evidence. Although the methodological quality of the included systematic reviews and meta-analyses which were evaluated by AMSTAR2.0 is generally poor, the identification of the relatively robust prognostic biomarkers of PDAC may guide better post-operative intervention and follow-up to prolong patients' survival.

COVID-19 Patients: A Systematic Review and Meta-Analysis of Laboratory Findings, Comorbidities, and Clinical Outcomes Comparing Medical Staff versus the General Population.
This review compared coronavirus disease 2019 (COVID-19) laboratory findings, comorbidities, and clinical outcomes in patients from the general population versus medical staff to aid diagnosis of COVID-19 in a more timely, efficient, and accurate way. Electronic databases were searched up to 23 March, 2020. The initial search yielded 6,527 studies. Following screening, 24 studies were included [18 studies (11,564 cases) of confirmed COVID-19 cases in the general public, and 6 studies (394 cases) in medical staff] in this review. Significant differences were observed in white blood cell counts ( < 0.001), lymphocyte counts ( < 0.001), platelet counts ( = 0.04), procalcitonin levels ( < 0.001), lactate dehydrogenase levels ( < 0.001), and creatinine levels ( = 0.03) when comparing infected medical staff with the general public. The mortality rate was higher in the general population than in medical staff (8% versus 2%). This review showed that during the early stages of COVID-19, laboratory findings alone may not be significant predictors of infection and may just accompany increasing C-reactive protein levels, erythrocyte sedimentation rates, and lactate dehydrogenase levels. In the symptomatic stage, the lymphocyte and platelet counts tended to decrease. Elevated D-dimer fibrin degradation product was associated with poor prognosis.
