A case report of rare complication of brucellosis infection: myocarditis and pneumonitis.

The involvement of cardiovascular or respiratory complications in cases of brucellosis are extremely rare. Herein, a case of myocarditis and pneumonia with pericardial effusion, pleural effusion and biliteral pleural thickening with pleural adhesion in a 35-year-old female patient, is described. Using next-generation sequencing, the patient was differentially diagnosed with Brucella-related myocarditis and pneumonitis, and treatment with oral doxycycline, rifampicin, and trimethoprim/sulfamethoxazole, along with intravenous gentamycin, was commenced. Following treatment, the patient was clinically improved. When a patient with brucellosis presents with chest pain, clinicians should be aware of this clinical manifestation. Next-generation sequencing may be used to identify pathogens and provide insights into the disease when appropriate cultures are negative.

Comparative effectiveness of different platelet-rich plasma for arthroscopic rotator cuff repair: A protocol for systematic review and network meta-analysis.

BACKGROUND: Rotator cuff tears are one of the most common injuries of the shoulder joint in adults. Arthroscopic rotator cuff repair (ARCR) has become the gold standard for the treatment of rotator cuff injuries, but it still has a high rate of retear. Platelet-rich plasma (PRP) has been widely used as an adjunct to ARCR. However, the comparative efficacy of different PRP for ARCR remain unclear. In order to evaluate the relative efficacy of PRP for individuals with ARCR, we will conduct a systematic review and network meta-analysis of randomized controlled trials. METHODS: A systematic literature search will be conducted in Embase, PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang Database, and Chinese Biomedical Literature Database will be searched up to October 2022. The primary outcome will focus on the retear rate at the last follow-up. The secondary outcomes include the Visual Analogue Scale for postoperative pain and functional capacity scores. The risk of bias for individual studies will be assessed according to the revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0). Data analysis will be performed using R 4.1.2. Publication bias will be examined using comparison-adjusted funnel plots and Egger's test using STATA 15.0. The quality of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS: The results of this study will be submitted to a peer-reviewed journal for publication. CONCLUSIONS: The review will compare the efficacy of different PRP for patients with ARCR. The result of the study will provide evidence-based medical evidence for ARCR with PRP augmentation.

Epidemic pattern of hand-foot-and-mouth disease in Xi'an, China from 2008 through 2015.

BACKGROUND: Hand, foot and mouth disease (HFMD) is an infectious disease caused by enteroviruses that has a severely impair for those high incidence countries such as China.The current study aimed to investigate the epidemic pattern of HFMD by time and region in Northwestern China. METHODS: All reported HFMD cases from 2008 to 2015 were collected from local Disease Control and Prevention.The HFMD was diagnosed in accordance with the guidebook provided by the National Health and Family Planning Commission of the People's Republic of China. RESULTS: A total of 154,869 cases of probable HFMD were reported. The overall incidence of HFMD has been increased from 91.68 per 100/000 in 2008 to 335.64 per 100/000 in 2015.The case mortality is decreased from 0.014 per100/000 to 0.011 per 100/000 during the time period. Most HFMD (93.82%) occurred in children younger than 5 years. The seasonal peak of HFMD infections occurred in April-July and September-November and Central regions of Xi'an city were the major locations of the clusters (incidence rate 245.75/100,000; relative risk 1.19, P < 0.01). EVA71 was the predominant enterovirus serotype, accounting for 50.0% of all reported HFMD cases since 2011.The most susceptible group infected by HFMD was children younger than 5 years, especially boys. CONCLUSIONS: Incidence of HFMD has been increasing in the past few years, however, the case fatality is decreasing. Season and region shall be considered as influence factors in the prevention of HFMD.

Green Tea Liquid Consumption Alters the Human Intestinal and Oral Microbiome.

SCOPE: GTPs (green tea polyphenols) exert anti-CRC (colorectal cancer) activity. The intestinal microbiota and intestinal colonization by bacteria of oral origin has been implicated in colorectal carcinogenesis. GT modulates the composition of mouse gut microbiota harmonious with anticancer activity. Therefore, the effect of green tea liquid (GTL) consumption on the gut and oral microbiome is investigated in healthy volunteers (n = 12). METHODS AND RESULTS: 16S sequencing and phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) analysis of both fecal and saliva samples (collected before intervention, after 2 weeks of GTL (400 mL per day) and after a washout period of one week) in healthy volunteers show changes in microbial diversity and core microbiota and difference in clear classification (partial least squares-discriminant analysis [PLS-DA]). An irreversible, increased FIR:BAC (Firmicutes to Bacteroidetes ratio), elevated SCFA producing genera, and reduction of bacterial LPS synthesis in feces are discovered in response to GTL. GTL alters the salivary microbiota and reduces the functional pathways abundance relevance to carcinogenesis. Similar bacterial networks in fecal and salivary microbiota datasets comprising putative oral bacteria are found and GTL reduces the fecal levels of Fusobacterium. Interestingly, both Lachnospiraceae and B/E (Bifidobacterium to Enterobacteriacea ratio-markers of colonization resistance [CR]) are negatively associated with the presence of oral-like bacterial networks in the feces. CONCLUSION: These results suggest that GTL consumption causes both oral and gut microbiome alterations.

Sub-anesthesia Dose of Isoflurane in 60% Oxygen Reduces Inflammatory Responses in Experimental Sepsis Models.

BACKGROUND: Sepsis is a major cause of mortality in Intensive Care Units. Anesthetic dose isoflurane and 100% oxygen were proved to be beneficial in sepsis; however, their application in septic patients is limited because long-term hyperoxia may induce oxygen toxicity and anesthetic dose isoflurane has potential adverse consequences. This study was scheduled to find the optimal combination of isoflurane and oxygen in protecting experimental sepsis and its mechanisms. METHODS: The effects of combined therapy with isoflurane and oxygen on lung injury and sepsis were determined in animal models of sepsis induced by cecal ligation and puncture (CLP) or intraperitoneal injection of lipopolysaccharide (LPS) or zymosan. Mouse RAW264.7 cells or human peripheral blood mononuclear cells (PBMCs) were treated by LPS to probe mechanisms. The nuclear factor kappa B (NF-κB) signaling molecules were examined by Western blot and cellular immunohistochemistry. RESULTS: The 0.5 minimum alveolar concentration (MAC) isoflurane in 60% oxygen was the best combination of oxygen and isoflurane for reducing mortality in experimental sepsis induced by CLP, intraperitoneal injection of LPS, or zymosan. The 0.5 MAC isoflurane in 60% oxygen inhibited proinflammatory cytokines in peritoneal lavage fluids (tumor necrosis factor-alpha [TNF-ß]: 149.3 vs. 229.7 pg/ml, interleukin [IL]-1ß: 12.5 vs. 20.6 pg/ml, IL-6: 86.1 vs. 116.1 pg/ml, and high-mobility group protein 1 [HMGB1]: 323.7 vs. 449.3 ng/ml; all P< 0.05) and serum (TNF-ß: 302.7 vs. 450.7 pg/ml, IL-1ß: 51.7 vs. 96.7 pg/ml, IL-6: 390.4 vs. 722.5 pg/ml, and HMGB1: 592.2 vs. 985.4 ng/ml; all P< 0.05) in septic animals. In vitro experiments showed that the 0.5 MAC isoflurane in 60% oxygen reduced inflammatory responses in mouse RAW264.7 cells, after LPS stimulation (all P< 0.05). Suppressed activation of NF-κB pathway was also observed in mouse RAW264.7 macrophages and human PBMCs after LPS stimulation or plasma from septic patients. The 0.5 MAC isoflurane in 60% oxygen also prevented the increases of phospho-IKKß/ß, phospho-IκBß, and phospho-p65 expressions in RAW264.7 macrophages after LPS stimulation (all P< 0.05). CONCLUSION: Combined administration of a sedative dose of isoflurane with 60% oxygen improves survival of septic animals through reducing inflammatory responses.

Association Between Consumption of Red and Processed Meat and Pancreatic Cancer Risk: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: The relationship between consumption of red and processed meat and pancreatic cancer risk is inconclusive. We conducted a systematic review and meta-analysis to analyze this relationship. METHODS: We performed a systematic search of PubMed, EMBASE, and the Web of Science to identify studies that examined associations between consumption of different kinds of meat with pancreatic cancer and were published through February 2016. By using data from these articles, we associated level of consumption with cancer risk and performed subgroup, meta-regression, and publication bias analyses. RESULTS: We collected and analyzed data from a total of 28 studies that involved 3,143,777 participants (11,325 consumers of red meat) and 2,904,866 participants (9955 consumers of processed meat). We observed statistically significant differences between consumers and non-consumers of these meats in case-control studies (red meat, P = .02; processed meat, P < .01) but not in cohort studies (red meat, P = .09; processed meat, P = .18). In cohort studies, a 100 g/day increase in red meat consumption was associated with significant increase in risk of pancreatic cancer (P = .01); a 50 g/day increase in processed meat consumption was not associated with significant increase in risk of pancreatic cancer (P = .90). In cohort studies, we observed associations in consumption of red meat by men and pancreatic cancer (P < .01) and consumption of processed meat by men and pancreatic cancer (P < .01) but no associations for women (red meat, P = .61; processed meat, P = .88). CONCLUSIONS: In a systematic review and meta-analysis, we found case-control but not cohort studies to associate consumption of red and processed meat with risk of pancreatic cancer. However, in cohort studies, consumption of red and processed meat appeared to increase risk of pancreatic cancer in men but not in women.

Dietary fruit, vegetable, fat, and red and processed meat intakes and Barrett's esophagus risk: a systematic review and meta-analysis.

The relationships between dietary fruit, vegetable, fat, and red and processed meat intakes and Barrett's esophagus (BE) risk remain inconclusive. We conducted a systematic review and meta-analysis to summarize the available evidence on these issues. PubMed, EMBASE and the Cochrane Library were searched for studies published from inception through October 2015. A total of eight studies were included in this analysis. Fruit intake was not associated with BE risk (OR = 0.65, 95% CI = 0.37-1.13), but vegetable intake was strongly associated with BE risk (OR = 0.45, 95% CI = 0.29-0.71). Saturated fat, red meat and processed meat intakes were not associated with BE risk with OR = 1.25 (95% CI = 0.82-1.91), OR = 0.85 (95% CI = 0.61-1.17) and OR = 1.03 (95% CI = 0.73-1.46), respectively. Dietary vegetable not fruits intake may be associated with decreased BE risk. Fat and red and processed meat intakes may not contribute to an increased BE risk. Well-designed, large prospective studies with better established dose-response relationships are needed to further validate these issues.

Epidemiology of Hepatitis B Virus Infection in China: Current Status and Challenges.

The prevalence of hepatitis B is high in China. Based on the National Disease Supervision Information Management System of China, the mean reported incidence of hepatitis B was 84.3 per 100,000 in China between 2005 and 2010. There are differences in population distribution based on region and ethnic group. Here, risk factors, virological characteristics, and prophylaxis of hepatitis B in China are reviewed. Although the prevalence of HBV infection is gradually declining, there are many challenges in HBV infection control, including higher prevalence in floating population, poor compliance of antiviral therapy, and high disease burden.
