Review
Changes in salivary markers have been largely assessed during different modalities of long-term and short-term basketball training across different basketball populations. The aim of this paper was to systematically review the literature assessing changes in salivary markers in basketball following long-term and short-term training periods. An electronic database search of articles published until October 2020 was completed in PubMed, SPORTDiscus, Scopus and Web of Science. Studies were then screened and selected using pre-defined selection criteria with 1080 articles identified. After removing 690 duplicates, 390 articles were included for screening, which revealed 15 articles that met the inclusion criteria. The main findings revealed no changes in testosterone (T), cortisol (C) or their ratio (T:C), while contrasting results were found in immunoglobulin A (IgA) and total protein (TP) levels across long-term periodized training periods in different basketball populations. The analysis of short-term training periods showed that strength-hypertrophy training induced higher C levels compared to a non-exercising day, one-power training and one-endurance training session in female basketball players, while no changes were evident for T and IgA. Moreover, the analysis of salivary markers in response to small-sided games (SSGs) documented a large-to-moderate increase in alpha-amylase (AA) from pre- to post-SSG and inconsistent results of C and T across differently designed SSGs. The current results provide a detailed description of salivary marker changes in response to different basketball long- and short-term training periods, which can help practitioners in designing sound training programmes to optimize players' fitness and health status across different phases of the season.

Review
BACKGROUND
Coronavirus disease 2019 (COVID-19) presents mainly with mild symptoms and involvement of the respiratory system. Acute pancreatitis has also been reported during the course of COVID-19.
OBJECTIVE
Our aim is to review and analyze all reported cases of COVID-19 associated acute pancreatitis, reporting the demographics, clinical characteristics, laboratory and imaging findings, comorbidities and outcomes.
DATA SOURCES
We conducted a systematic search of Pubmed/MEDLINE, SciELO and Google Scholar to identify case reports and case series, reporting COVID-19 associated acute pancreatitis in adults.
STUDY SELECTION
There were no ethnicity, gender or language restrictions. The following terms were searched in combination:"COVID-19" OR "SARS-CoV-2" OR "Coronavirus 19" AND "Pancreatic Inflammation" OR "Pancreatitis" OR "Pancreatic Injury" OR "Pancreatic Disease" OR "Pancreatic Damage". Case reports and case series describing COVID-19 associated acute pancreatitis in adults were included. COVID-19 infection was established with testing of nasal and throat swabs using reverse transcription polymerase chain reaction. The diagnosis of acute pancreatitis was confirmed in accordance to the revised criteria of Atlanta classification of the Acute Pancreatitis Classification Working Group. Exclusion of other causes of acute pancreatitis was also required for the selection of the cases.
DATA EXTRACTION
The following data were extracted from each report: the first author, year of publication, age of the patient, gender, gastrointestinal symptoms due to acute pancreatitis, respiratory-general symptoms, COVID-19 severity, underlying diseases, laboratory findings, imaging features and outcome.
DATA SYNTHESIS
Finally, we identified and analyzed 31 articles (30 case reports and 1 case series of 2 cases), which included 32 cases of COVID-19 induced acute pancreatitis.
CONCLUSION
COVID-19 associated acute pancreatitis affected mostly females. The median age of the patients was 53.5 years. Concerning laboratory findings, lipase and amylase were greater than three times the ULN while WBC counts and CRP were elevated in the most of the cases. The most frequent gastrointestinal, respiratory and general symptom was abdominal pain, dyspnea and fever, respectively. The most common imaging feature was acute interstitial edematous pancreatitis and the most frequent comorbidity was arterial hypertension while several patients had no medical history. The outcome was favorable despite the fact that most of the patients experienced severe and critical illness.
LIMITATIONS
Our results are limited by the quality and extent of the data in the reports. More specifically, case series and case reports are unchecked, and while they can recommend hypotheses they are not able to confirm robust associations.
CONFLICT OF INTEREST
None.

Various studies have shown that the microbial proteins are often more stable than belongs to other sources like plant and animal origin. Hence, the interest in microbial enzymes has gained much attention due to many potential applications like bioenergy, biofuel production, biobleaching, bioconversion and so on. Additionally, recent trends revealed that the interest in isolating novel microbes from harsh environments have been the main focus of many scientists for various applications. Basically, industrially important enzymes can be categorized into mainly three groups: carbohydrases, proteases, and lipases. Among those, the enzymes especially carbohydrases involved in production of sugars. Carbohydrases include amylases, xylanases, pectinases, cellulases, chitinases, mannases, laccases, ligninases, lactase, glucanase, and glucose oxidase. Thus, here, an approach has been made to highlight five enzymes namely amylase, cellulase, laccase, pectinase, and xylanase from different sources with special emphasis on their properties, mechanism, applications, production optimization, purification, molecular approaches for its enhanced and stable production, and also biotechnological perspectives of its future development. Also, green and sustainable catalytic conversion strategies using nanoparticles of these enzymes have also been discussed. This review will provide insight into the carbohydrases importance and their usefulness that will help to the researchers working in this field.

Minerva Dental and Oral Science Aug 2022Compare through case-control studies, the salivary characteristics of patients with and without BMS.
INTRODUCTION
Compare through case-control studies, the salivary characteristics of patients with and without BMS.
EVIDENCE ACQUISITION
Searches in Embase, PubMed, Web of Science, Scopus, Cochrane, and BIREME were conducted for the identification of case-controls studies reported.
EVIDENCE SYNTHESIS
Thirty-three studies were included, of which 26 articles evaluated OSB, 17 SRF, and 7 SE. Nineteen organic biomarkers showed higher levels in BMS patients, the two most indicated being α-amylase and cortisol. Ten organic biomarkers, including Tumor Necrosis Factor-alpha (TNF-α) and IL-6, showed lower levels in BMS patients. Regarding salivary flow rate (SFR), five articles indicated that BMS patients have less unstimulated SFR (uSRF)Two articles indicate that stimulated SFR (sSRF) is lower in BMS patients nevertheless, but eight did not show differences. Sialochemical analysis revealed that sodium (Na), chloride (Cl), potassium (K), sodium (Na), and calcium (Ca), showed higher levels in BMS patients according to three studies, but two studies did not establish any differences. Two study established that BMS patients have lower Mg salivary levels.
CONCLUSIONS
Qualitative salivary characteristics suggest that BMS has neuropathic, inflammatory, emotional, immune, and hormonal involvements. BMS can be associated with changes in salivary biomarkers of inflammation and oxidative stress, is related to anxiety and degree of pain.

Review
Autoimmune pancreatitis (AIP) is a rare etiological type of chronic pancreatitis. The clinical and radiological presentation of AIP often resembles that of pancreatic cancer. Identifying non-invasive markers for their early distinction is of utmost importance to avoid unnecessary surgery or a delay in steroid therapy. Thus, this systematic review was conducted to revisit all current evidence on the clinical utility of different serum biomarkers in diagnosing AIP, distinguishing AIP from pancreatic cancer, and predicting disease course, steroid therapy response, and relapse. A systematic review was performed for articles published up to August 2021 by searching electronic databases such as MEDLINE, Web of Science, and EMBASE. Among 5123 identified records, 92 studies were included in the qualitative synthesis. Apart from immunoglobulin (Ig) G4, which was by far the most studied biomarker, we identified autoantibodies against the following: lactoferrin, carboanhydrase II, plasminogen-binding protein, amylase-α2A, cationic (PRSS1) and anionic (PRSS2) trypsinogens, pancreatic secretory trypsin inhibitor (PSTI/SPINK1), and type IV collagen. The identified novel autoantigens were laminin 511, annexin A11, HSP-10, and prohibitin. Other biomarkers included cytokines, decreased complement levels, circulating immune complexes, -glycan profile changes, aberrant miRNAs expression, decreased IgA and IgM levels, increased IgE levels and/or peripheral eosinophil count, and changes in apolipoprotein isoforms levels. To our knowledge, this is the first systematic review that addresses biomarkers in AIP. Evolving research has recognized numerous biomarkers that could help elucidate the pathophysiological mechanisms of AIP, bringing us closer to AIP diagnosis and its preoperative distinction from pancreatic cancer.

Post-ERCP pancreatitis (PEP) is the most common complication attributed to the procedure, its incidence being approximately 9.7 %. Numerous studies have evaluated the predictive efficacy of post-procedure serum amylase and lipase levels but with varied procedure-to-test time intervals and cut-off values. The aim of this meta-analysis was to present pooled data from available studies to compare the predictive accuracies of serum amylase and lipase for PEP. A total of 18 studies were identified after a comprehensive search of various databases until June 2021 that reported the use of pancreatic enzymes for PEP. The sample size consisted of 11,790 ERCPs, of which PEP occurred in 764 (6.48 %). Subgroups for serum lipase and amylase were created based on the cut-off used for diagnosing PEP, and meta-analysis was done for each subgroup. Results showed that serum lipase more than three to four times the upper limit of normal (ULN) performed within 2 to 4 hours of ERCP had the highest pooled sensitivity (92 %) for PEP. Amylase level more than five to six times the ULN was the most specific serum marker with a pooled specificity of 93 %. Our analysis indicates that a lipase level less than three times the ULN within 2 to 4 hours of ERCP can be used as a good predictor to rule out PEP when used as an adjunct to patient clinical presentation. Multicenter randomized controlled trials using lipase and amylase are warranted to further evaluate their PEP predictive accuracy, especially in high-risk patients.

Meta-Analysis Review
BACKGROUND
Virtual reality (VR) research probes stress environments that are infeasible to create in the real world. However, because research simulations are applied to narrow populations, it remains unclear if VR simulations can stimulate a broadly applicable stress-response. This systematic review and meta-analysis was conducted on studies using VR stress tasks and biomarkers.
METHODS
Included papers (N = 52) measured cortisol, heart rate (HR), galvanic skin response (GSR), systolic blood pressure (SBP), diastolic blood pressure (DBP), respiratory sinus arrhythmia (RSA), parasympathetic activity (RMSSD), sympathovagal balance (LF/HF), and/or salivary alpha-amylase (sAA). Effect sizes (ES) and confidence intervals (CI) were calculated based on standardized mean change of baseline-to-peak biomarker levels.
RESULTS
From baseline-to-peak (ES, CI), analyses showed a statistically significant change in cortisol (0.56, 0.28-0.83), HR (0.68, 0.53-0.82), GSR (0.59, 0.36-0.82), SBP (.55, 0.19-0.90), DBP (.64, 0.23-1.05), RSA (-0.59, -0.88 to -0.30), and sAA (0.27, 0.092-0.45). There was no effect for RMSSD and LF/HF.
CONCLUSION
VR stress tasks elicited a varied magnitude of physiological stress reactivity. VR may be an effective tool in stress research.

Meta-Analysis
INTRODUCTION
The prevalence of increased pancreatic enzymes (elevated serum amylase and/or lipase) and its relationship to clinical outcomes in patients with coronavirus disease 2019 (COVID-19) infection is not known.
METHODS
A systematic review and meta-analysis of relevant studies reporting prevalence and impact of increased pancreatic enzymes (defined as an elevation in amylase and/or lipase levels above the upper limit of normal [ULN] value) in COVID-19 was undertaken.
RESULTS
A total of 36,496 patients from 21 studies were included for this meta-analysis. The overall prevalence and mortality for increased pancreatic enzymes (>ULN) in COVID-19 were 25.4% (95% CI, 15.8%-36.2%) and 34.6% (95% CI, 25.5%-44.4%), respectively. The overall prevalence and mortality for increased pancreatic enzymes (>3 × ULN) were 6.1% (95% CI, 3.6%-9.2%) and 39.2% (95% CI, 18.7%-61.6%), respectively. Patients with increased pancreatic enzymes, including elevated serum lipase or amylase of either type, had worse clinical outcomes, including need for ICU admission, mechanical ventilation and mortality.
DISCUSSION
Increased pancreatic enzymes is frequent and may exacerbate the consequences of COVID-19 infection.

Meta-Analysis
Acute pancreatitis (AP) is an inflammatory disease, and NLRP3 inflammasome activation is involved in the pathogenesis of AP. Previous research showed that inhibition of NLRP3 inflammasome may exert protective effects on animal models of AP and reduces disease severity. The aim of this systematic review and meta-analysis is to evaluate the effects of drug treatment of NLRP3 inflammasome on the outcomes of experimental AP. PubMed, Embase, Medline, and Web of Science databases were searched for relevant articles without language restrictions. The main outcomes for this study included local pancreatic injury, the incidence of systemic inflammatory responses, and the incidence of organ failure. Twenty-eight animal studies including 556 animals with AP were included in the meta-analysis. Compared with controls, inhibition of NLRP3 inflammasome significantly reduced the pancreatic histopathological scores, serum amylase, and lipase levels. In addition, inhibition of NLRP3 inflammasome reduced the levels of circulating inflammatory cytokines, as well as mitigating severity of AP-associated acute lung injury and acute intestinal injury. To conclude, inhibition of NLRP3 inflammasome has protective effects on AP by mitigating organ injury and systemic inflammation in animal studies, indicating that NLRP3 inflammasome holds promise as a target for specific AP therapy.

Review
BACKGROUND
Saliva biomarkers could be easily used as a noninvasive alternative tool for diagnosing cystic fibrosis (CF) disease. In this study, the significance of changes in salivary compositions in patients with CF was systematically reviewed.
METHODS
An electronic search was utilized to include studies published in English, with case-control, cohort, or cross-sectional design. The evaluated salivary components were extracted and summarized. The included studies were assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist.
RESULTS
Out of 498 identified studies, nine met the eligibility criteria. Salivary electrolytes showed a substantial alteration in the CF group, especially with chloride and sodium. Total protein concentration was higher in patients with CF. However, SCN- concentration was lower in patients with CF. In addition, a reduction in the salivary flow rate and amylase levels was found in patients with CF.
CONCLUSION
Alterations in salivary biomarkers among patients with CF could be used as a promising diagnostic tool for cystic fibrosis.
