Abstract
Our understanding of COVID-19 vaccinations and their impact on health and mortality has evolved substantially since the first vaccine rollouts. Published reports from the original randomized phase 3 trials concluded that the COVID-19 mRNA vaccines could greatly reduce COVID-19 symptoms. In the interim, problems with the methods, execution, and reporting of these pivotal trials have emerged. Re-analysis of the Pfizer trial data identified statistically significant increases in serious adverse events (SAEs) in the vaccine group. Numerous SAEs were identified following the Emergency Use Authorization (EUA), including death, cancer, cardiac events, and various autoimmune, hematological, reproductive, and neurological disorders. Furthermore, these products never underwent adequate safety and toxicological testing in accordance with previously established scientific standards. Among the other major topics addressed in this narrative review are the published analyses of serious harms to humans, quality control issues and process-related impurities, mechanisms underlying adverse events (AEs), the immunologic basis for vaccine inefficacy, and concerning mortality trends based on the registrational trial data. The risk-benefit imbalance substantiated by the evidence to date contraindicates further booster injections and suggests that, at a minimum, the mRNA injections should be removed from the childhood immunization program until proper safety and toxicological studies are conducted. Federal agency approval of the COVID-19 mRNA vaccines on a blanket-coverage population-wide basis had no support from an honest assessment of all relevant registrational data and commensurate consideration of risks versus benefits. Given the extensive, well-documented SAEs and unacceptably high harm-to-reward ratio, we urge governments to endorse a global moratorium on the modified mRNA products until all relevant questions pertaining to causality, residual DNA, and aberrant protein production are answered.

Abstract
High levels of cholesterol and triglycerides may have a negative effect on the immune system and bone health, leading to lower bone mineral density, an increased risk of osteoporosis, and bone fractures, and could therefore also be related to a significant worsening of peri-implant health. The purpose of the following study was to evaluate whether the altered lipid profile in patients who undergo implant insertion surgery represents a prognostic factor capable of influencing clinical outcomes. This prospective observational study was conducted on 93 subjects; patients were required to have taken blood tests to obtain triglycerides (TG), total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels prior to the surgical procedure to classify them according to current American Heart Association guidelines. The outcomes considered were marginal bone loss (MBL) 3 years after implant placement, full-mouth plaque score (FMPS), and full-mouth bleeding score (FMBS) 3 years after surgery. A statistically significant correlation was found between hypertriglyceridemia and MBL as well as between total cholesterol and MBL. There is no statistically significant correlation between the variables analyzed and the secondary outcomes 3 years after implant placement. Peri-implant marginal bone loss may be influenced by hyperlipidemia. However, further studies are needed, with larger samples and more extensive follow-ups, to confirm these results.

Journal of healthcare engineering. 2022;:7100238
Abstract
The aim of this study was to study the effect of early nutritional assessment and nutritional support on immune function and clinical prognosis of critically ill children. 90 critically ill children at the same level of severity admitted to the pediatric intensive care unit (PICU) of our hospital (June 2019-June 2020) were chosen as the research objects and were equally separated into the experimental group and the control group by the random number table method. The children in the control group were admitted to the PICU according to the routine process, and the nutritional support was provided to the malnourished ones. After admission to the PICU, the children in the experimental group were given nutritional assessment, nutritional risk screening, and nutritional support according to the screening results. The PICU stay time and total hospitalization time of the experimental group were obviously shorter than those of the control group (P < 0.05), the hospitalization expenses of the experimental group were obviously lower than those of the control group (P < 0.05), the clinical outcomes and immune function of the experimental group were obviously better than those of the control group (P < 0.05), and the nutrition indicators of the experimental group were obviously higher than those of the control group (P < 0.05). Early nutritional assessment and nutritional support can effectively improve the immune function and reduce the incidence of adverse clinical outcomes of critically ill children, which are worthy of clinical application and promotion.

Abstract
BACKGROUND Many studies have demonstrated that vitamin D has clinical benefits when used to treat patients with chronic obstructive pulmonary disease (COPD). However, most of these studies have insufficient samples or inconsistent results. The aim of this meta-analysis was to evaluate the effects of vitamin D therapy in patients with COPD. METHODS We performed a comprehensive retrieval in the following electronic databases: PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and Chinese Scientific Journals Database (VIP). Two trained reviewers identified relevant studies, extracted data information, and then assessed the methodical quality by the Cochrane risk of bias assessment tool, independently. Then, the meta-analyses were conducted by RevMan 5.4, binary variables were represented by risks ratio (RR), and continuous variables were represented by mean difference (MD) or standardized mean difference (SMD) to assess the efficacy of vitamin D therapy in patients with COPD. Then, publication bias assessment was conducted by funnel plot analysis. Finally, the quality of evidence was assessed by the GRADE system. RESULTS A total of 15 articles involving 1598 participants were included in this study. The overall results showed a statistical significance of vitamin D therapy in patients with COPD which can significantly improve forced expiratory volume in 1 second (FEV1) (MD: 5.69, 95% CI: 5.01-6.38,P < 0.00001,I2 = 51%) and FEV1/FVC (SMD:0.49, 95% CI: 0.39-0.60,P < 0.00001,I2 = 84%); and serum 25 (OH)D (SMD:1.21, 95% CI:1.07-1.34,P < 0.00001,I2 = 98%) also increase CD3+ Tcells (MD: 6.67, 95% CI: 5.34-8.00,P < 0.00001,I2 = 78%) and CD4+ T cells (MD: 6.00, 95% CI: 5.01-7.00,P < 0.00001,I2 = 65%); and T lymphocyte CD4+/CD8+ ratio (MD: 0.41, 95% CI: 0.20-0.61,P = 0.0001,I2 = 95%) obviously decrease CD8+ Tcells(SMD: -0.83, 95% CI: -1.05- -0.06,P < 0.00001,I2 = 82%), the times of acute exacerbation (RR: 0.40, 95% CI: 0.28-0.59,P < 0.00001,I2 = 0%), and COPD assessment test (CAT) score (MD: -3.77, 95% CI: -5.86 - -1.68,P = 0.0004,I2 = 79%). CONCLUSIONS Our analysis indicated that vitamin D used in patients with COPD could improve the lung function (FEV1 and FEV1/FVC), the serum 25(OH)D, CD3+ T cells, CD4 + T cells, and T lymphocyte CD4+/CD8+ ratio and reduce CD8+ T cells, acute exacerbation, and CAT scores.

Computational and mathematical methods in medicine. 2022;:4648784
Abstract
OBJECTIVE To investigate the influencing factors of pneumonia when pediatric leukemia patients are hospitalized and propose coping strategies. METHODS A retrospective study and analysis of the inpatient medical records of 183 children with leukemia in our hospital from August 2017 to August 2020. A total of 93 cases were in the case group of children with pneumonia, and the rest were 90 cases in the control group. Case data from two groups of children were compared, and the monofactor analysis of pneumonia occurred. The P < 0.05 was selected for its multivariate logistic regression analysis, and its coping strategy was proposed. RESULTS After multivariate logistic retrospective analysis, it was found that the main influencing factors were neutrophils, white blood cells, vitamin D, and cellular immunity (P < 0.05). A review of the two sets of pathological data found that high doses of cytarabine reduced the incidence of pneumonia in children with leukemia (P < 0.05). CONCLUSION A timely understanding of the influencing factors of pediatric diabetes mellitus and pneumonia and the early application of cytarabine can reduce the incidence of pneumonia during the child's hospitalization.

Li, S, Li, H, Wang, J, Yin, L
Journal of healthcare engineering. 2022;:7375006
Abstract
In order to probe into the impact of high-flux dialysis and hemodiafiltration on patients with chronic rental failure, this paper selects in total 92 cases with chronic renal failure receiving hemodialysis from November 2018 to July 2021, allocating them into two groups based on the random table, each with 46 cases. The control group received hemodiafiltration, the observation group is given high-flux hemodialysis, and we compared serum inflammatory factor level and antioxidant factor level before and after treatment, as well as cellular immune factor level (CD3+, CD4+) and humoral immune factor level (IgE) before and after treatment in the two groups; the renal function, serum total calcium ion level, and serum phosphorus ion level in the two groups were compared before and after treatment, as well as the proportion of metabolic abnormalities in calcium and phosphorus ion levels during treatment; the trend of changes in axillary temperature during treatment in the two groups is analyzed. After treatment, serum inflammatory factor level (hs-CRP & TNF-α) is lower than that in the control group (P < 0.05), antioxidant factor level (MDA) is lower than that in the control group (P < 0.05), and SOD level is higher than that in the control group (P < 05). After treatment CD3+ and CD4+ levels in the observation group are higher than those in the control group (P < 0.05). For patients with chronic renal failure, high-flux hemodialysis is available to better reduce inflammatory response, improve antioxidant and immune capacity in the body, and help maintain calcium and phosphorus metabolic balance.

Liao, N, Xu, C, Zheng, S, Wang, R
Journal of healthcare engineering. 2022;:8281558
Abstract
The aim of this study was to investigate the effects of double-channel anastomosis versus esophagojejunostomy on postoperative recovery and complications after laparoscopic D2 radical gastrectomy for early proximal gastric cancer. The cases were collected from 100 patients with early proximal gastric cancer admitted to our hospital from January 2017 to January 2021. According to different surgical methods, they were divided into control group (total gastrectomy + esophagojejunal anastomosis) and experimental group (D2 radical resection + double-channel anastomosis). The two groups were compared in terms of clinical outcomes (operative time, intraoperative blood loss, number of lymph nodes dissected, digestive tract anastomosis time, postoperative exhaust, and hospitalization days), postoperative complications, and nutritional status; the expression of T lymphocyte subsets in peripheral blood of the two groups was detected to reflect the recovery of immune ability. There was no significant difference between the observation group and the control group in clinical operation effect indexes (P < 0.05). The incidence of complications of dumping syndrome and reflux esophagitis in the observation group was significantly lower than that in the control group (P < 0.05). In terms of postoperative nutritional status, the ratio of plasma albumin level and body weight restored to operation at 12 and 24 weeks after operation in the observation group was significantly higher than that in the control group (P < 0.05). 3 months after the operation, the levels of CD3 +, CD4 + cell subsets, and CD4+/CD8+ index reflecting the recovery of immune ability in the observation group were significantly higher than those in the observation group (P < 0.05). The application of double-channel anastomosis in laparoscopic D2 radical gastrectomy for early proximal gastric cancer has a better effect on reducing complications and promoting postoperative recovery, which is of great application value.
