Effect of folic acid combined with pravastatin on arteriosclerosis in elderly hypertensive patients with lacunar infarction

This study aimed to assess the effect of folic acid combined with pravastatin on atherosclerosis-related indexes in elderly patients with hypertension complicated with lacunar cerebral infarction.A total of 134 elderly hypertensive patients with lacunar cerebral infarction were randomly divided into 3 groups using the random number table method. Group A, the folic acid group, had 45 cases and received low-dose folic acid (0.8 mg/d) treatment on the basis of antihypertensive treatment. Group B, the pravastatin group, had 45 cases and received pravastatin (20 mg/d) treatment on the basis of antihypertensive treatment. Group C, the folic acid combined with the pravastatin group, had 44 cases. Members of this group received pravastatin (20 mg/d) and low-dose folic acid (0.8 mg/d) based on antihypertensive treatment. Levels of folic acid, homocysteine (Hcy), tumor necrosis factor alpha (TNF-a), matrix metallopeptidase 9 (MMP-9), cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were measured by ELISA before treatment in all 3 groups. Carotid intima-media thickness (IMT) was measured using ultrasound, and systolic and diastolic blood pressure were measured with a mercury column. After 8 weeks of treatment, the levels of folic acid, Hcy, TNF-a, MMP-9, TC, LDL-C, and systolic and diastolic blood pressure were compared among the 3 groups. IMT levels were measured at 12 weeks of treatment.After 8 weeks of treatment, compared with group B, patients in groups A and C had folic acid levels significantly higher than baseline levels, with significantly lower Hcy levels (both P < .05). Patients in group C presented significantly decreased TNF-a, MMP-9, TC, and LDL-C levels and systolic and diastolic blood pressure after 8 weeks of treatment, compared with those in groups A and B (both P < .05). These patients also showed significantly decreased IMT levels compared with those in the other groups (P < .05).Low-dose folic acid combined with pravastatin in elderly patients with lacunar cerebral infarction can reduce the level of homocysteine, improve the degree of carotid atherosclerosis, protect vascular endothelium, and reduce blood lipids and blood pressure, presenting better benefits than pravastatin alone.     

Application effect of initiation of enteral nutrition at different time periods after surgery in neonates with complex congenital heart disease: A retrospective analysis

Early enteral nutrition (EN) promotes the recovery of critically ill patients, but the initiation time for EN in neonates after cardiac surgery remains unclear.This study aimed to investigate the effect of initiation time of EN after cardiac surgery in neonates with complex congenital heart disease (CHD).Neonates with complex CHD admitted to the CICU from January 2015 to December 2017 were retrospectively analyzed. Patients were divided into the 24-hour Group (initiated at 24 hours after surgery in 2015) (n = 32) and 6-hour Group (initiated at 6 hours after surgery in 2016 and 2017) (n = 66). Data on the postoperative feeding intolerance, nutrition-related laboratory tests (albumin, prealbumin, retinol binding protein), and clinical outcomes (including duration of mechanical ventilation, CICU stay, and postoperative hospital stay) were collected.The incidence of feeding intolerance was 56.3% in 24-hour Group and 39.4%, respectively (P = .116). As compared to 24-hour Group, prealbumin and retinol binding protein levels were higher (160.7 ± 64.3 vs 135.2 ± 28.9 mg/L, P = .043 for prealbumin; 30.7 ± 17.7 vs 23.0 ± 14.1 g/L P = .054 for retinol-binding protein). The duration of CICU stay (9.4 ± 4.5 vs 13.3 ± 10.4 day, P = .049) and hospital stay (11.6 ± 3.0 vs 15.8 ± 10.3 day, P = .028) were shorter in 6-hour Group.Early EN improves nutritional status and clinical outcomes in neonates with complex CHD undergoing cardiac surgery, without significant feeding intolerance.     

Factors associated with hyperhomocysteinemia in relatively healthy Taiwanese adults: A retrospective medical record study

Elevated homocysteine levels have been proposed as a risk factor for cardiovascular disease. The aim of this study was to evaluate factors associated with hyperhomocysteinemia in relatively healthy Taiwanese adults.A retrospective cross-sectional study was conducted using data from the health examination database in a medical center located in southern Taiwan. Hyperhomocysteinemia was defined as a plasma homocysteinemia level >15 μmol/L. Factors associated with hyperhomocysteinemia were evaluated using univariate and multiple stepwise logistic regression analyses.A total of 817 adults with a mean age of 55.5 years were included in the present study, and of them, 67 (8.2%) had hyperhomocysteinemia. Results from multiple logistic regression analysis showed that male sex (Odd ratio [OR] = 12.28, 95% CI = 2.94–51.27, P = .001), advanced age (OR = 1.37 per 10 years, 95% CI = 1.06–1.77, P = .017), triglycerides (OR = 1.02 per 10 mg/dL, 95% CI = 1.01–1.04, P = .010), and uric acid (OR = 1.27, 95% CI = 1.09–1.49, P = .004) were significantly and independently associated with hyperhomocysteinemia.In this retrospective medical record study, male sex, advanced age, higher plasma level of triglyceride, and uric acid were significantly associated with hyperhomocysteinemia in relatively healthy Taiwanese adults.     

Association of plasma polyunsaturated fatty acids with arterial blood pressure: A Mendelian randomization study

High polyunsaturated fatty acids (PUFAs) intake is recommended for primary and secondary prevention of cardiovascular disease (CVD). However, the association of PUFAs with blood pressure (BP) is still controversial. In the present study, two-sample Mendelian randomization (MR) analysis was performed to investigate the causal relationship of PUFAs with BP, including systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP).Genetic instruments and summary statistics for two-sample MR analysis were obtained from 3 large-scale genome-wide association studies (GWASs). Eight single nucleotide polymorphisms (SNPs) significantly (P < 5 × 10⁻⁸) related to 6 PUFAs were used as instrumental variables. Conventional inverse-variance weighted method was adopted to evaluate the causality of PUFAs with BP; the Weighted Median, MR-egger, and Leave-one-out method were used for sensitivity analyses.As a result, there was no evidence of a causal association between all PUFAs and SBP. In addition, arachidonic acid (AA, β = −0.04, P < .001) and eicosapentaenoic acid (EPA, β = −0.47, P = .02) were negatively associated with DBP, while linoleic acid (LA, β = 0.03, P = .005) and α-linolenic acid (ALA, β = 3.83, P < .001) were positively associated with DBP. There was no evidence of a causal relationship between either docosapentaenoic acid (DPA) or docosahexaenoic acid (DHA) with DBP.In conclusion, a genetic predisposition to plasma polyunsaturated fatty acid (PUFA) had a divergent effect on DBP, independent of SBP. It suggested that it is helpful for lower DBP level to supplemental intake of AA and EPA or promote the conversion of LA and ALA to AA and EPA respectively, which need to be further validated with randomized controlled studies.     

Efficacy and safety of nitrate supplementation on exercise tolerance in chronic obstructive pulmonary disease: A systematic review and meta-analysis

Background:Exercise intolerance was prevalent in people with chronic obstructive pulmonary disease (COPD) and had a detrimental effect on the quality of life. We aimed to evaluate the efficacy and safety of nitrate supplementation in exercise tolerance of people with COPD.Methods:We searched medical databases including Cochrane Library, EMBASE, and PubMed from inception to October 2020 for randomized control trials in treating COPD with nitrate supplementation.Results:Nine trials were identified. Compared with placebo, nitrate supplementation has no significant effect on the following variables: exercise endurance time (standard mean difference [SMD]: 0.06; 95% confidence interval [CI]: –0.39 to 0.52; P = .79), exercise capacity (SMD: 0.30; 95% CI: –0.21 to 0.80; P = .25), oxygen consumption (SMD: –0.04; 95% CI: –0.33 to 0.25; P = .80), resting systolic blood pressure (MD: –2.84; 95% CI: –8.46 to 2.78; P = .32), systolic blood pressure after exercise (MD: –4.66; 95% CI –15.66 to 6.34; P = .41), resting diastolic blood pressure (MD: 0.89; 95% CI: –4.41 to 6.19; P = .74), diastolic blood pressure after exercise (MD: –0.21; 95% CI: –5.51 to 5.10; P = .94), heart rate (MD: –2.52; 95% CI: –7.76 to 2.73; P = .35), and arterial oxygen saturation (MD: –0.44; 95% CI: –2.38 to 1.49; P = .65). No severe adverse effects from nitrate supplementation were reported in the included trails.Conclusion:Current evidence suggests that nitrate supplementation may be safe but ineffective for improving exercise tolerance in people with COPD.     

Improvement in social anxiety following a return-to-work intervention for patients with depression

Purpose:To retrospectively examine depression and social anxiety improvement in patients on sick leave due to depression who participated in a return-to-work intervention (RTW-I) program.Methods:Patients visited a psychiatric outpatient clinic simulating workplaces to learn recurrence prevention skills through RTW-Is, including group cognitive behavioral therapy, from April 1, 2013, to September 30, 2017. The Beck Depression Inventory-Second Edition (BDI-II), Social Adaptation Self-Evaluation Scale (SASS), and Liebowitz Social Anxiety Scale (LSAS) scores of 112 patients were analyzed before and after the intervention program. Missing postprogram data were substituted using the last observation carried forward scores. Next, 45 patients who responded to the work continuity survey 1 year after RTW-I were categorized into Group A (patients who continued working: 37) and Group B (those who did not continue: 8).Results:The mean BDI-II scores significantly decreased from preintervention 19.4 to postintervention 7.9 (t = 13.303, P < .001). The mean SASS scores significantly increased from preintervention 31.9 to postintervention 36.0 (t = −5.953, P < .001). The mean LSAS scores significantly decreased from preintervention 54.7 to postintervention 37.0 (t = 8.682, P < .001), and all scores demonstrated an improvement. Patients who continued working showed improved depressive and social anxiety symptoms. The BDI-II and SASS scores showed no significant differences between the groups, but the postintervention LSAS scores were significantly different (P = .041). LSAS score changes: Group A = −26.2; Group B = −9.8; estimated difference: −17.920, 95% CI: −32.181 to −3.659, P = .015.Conclusions:The RTW-I program improved depressive and social anxiety symptoms. Patients with improved scores continued working for 1 year after the intervention.Trial registration: This trial was retrospectively registered with the UMIN Clinical Trial Registry (UMIN-CTR) (ID: UMIN000037662) on August 10, 2019.     

Personalized tourniquet pressure may be a better choice than uniform tourniquet pressure during total knee arthroplasty: A PRISMA-compliant systematic review and meta-analysis of randomized-controlled trials

Background:Pneumatic tourniquets are widely used in total knee arthroplasty (TKA). Some surgeons prefer a uniform tourniquet inflation pressure (UTIP) for all patients; others use personalized tourniquet inflation pressures (PTIP) based on systolic blood pressure and limb occlusion pressure. However, no consensus exists regarding the optimal mode of inflation pressure during TKA. This review aimed to appraise if personalized tourniquet inflation pressures are better than uniform tourniquet inflation.Methods:The databases (Web of Science, Embase, PubMed, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CBM, CNKI, VIP, Wanfang) were searched on March 2021 to systematically identify and screen the literature for randomized controlled trials involving PTIP and UTIP during total knee arthroplasty.Results:Thirteen randomized controlled trials, involving 1204 TKAs (1201 patients) were included in the systematic review. The meta-analysis identified a trend toward less visual analogue scale (VAS) score at rest with PTIP group at 1 day (P = .002), 2 to 3 days (P = .01), and less VAS score at activity 1 day (P < .0001), 2 to 3 days after the operation (P < .00001), and discharge (P < .0001). No significant difference was found between the groups in terms of VAS score at rest when discharge (P = 1.0). We also found no significant difference in terms of intraoperative blood loss (P = .48), total blood loss (P = .15), lower limb vein thrombosis (P = .42), and thigh bullae (P = .17). However, in the PTIP group, we found a significant higher hospital for special surgery (HSS) score (P = .007), broader knee Range of motion (P = .02), less rate of thigh ecchymosis (P = .00001), and shorter thigh circumference at 1 day (P = .006), 2 to 3 days (P = .0005), and discharge (P = .02).Conclusion:PTIP provides a similar bloodless surgical field compared with the conventional UTIP. Furthermore, PTIP provides less pain intensity, thigh circumference, rate of thigh ecchymosis, higher hospital for special surgery, and better initial recovery of knee flexion in total knee arthroplasty. Therefore, we recommend using a PTIP method during TKA. More adequately powered and better-designed randomized controlled trials studies with long-term follow-up are required to produce evidence-based guidelines regarding the PTIP method.     

The value of anti-rods and rings antibodies in patients with nonhepatitis virus infection: A single-center retrospective study from Southwest China

The aim of this study was to retrospectively investigate the clinical significance of anti-rods and rings (anti-RR) antibodies in nonhepatitis virus infection patients from Southwest China.Anti-RR antibodies were determined by indirect immunofluorescence assay in a group of 19,935 individuals with antinuclear antibodies test from January 2017 to December 2019. The laboratory and clinical data were collected. Finally, 66 samples with anti-RR antibodies (0.33%) were detected.In Wilcoxon rank sum test, gamma glutamyl transferase (Z = −3.364, P = .001), alpha-l-fucosidase (AFU) (Z = −2.312, P = .021), uric acid (Z = −1.634, P = .047) and red blood cell distribution width (Z = −2.285, P = .022) were higher in metabolic disease group than nonmetabolic disease group. In independent-samples t test, endogenous creatinine clearance was higher in metabolic disease group than nonmetabolic disease group (t = 2.061, P = .045). During the follow-up period of 37 patients with anti-RR antibodies for 1 to 60 months, the titers of anti-RR were significantly increased in the metabolic disease group (Z = −2.346, P = .019). In binary logistic regression analysis, triglycerides (odds ratio 3.679, 95% confidence interval 1.467–24.779, P = .048) was associated with elevated titers of anti-RR antibodies.In summary, anti-RR in non-hepatitis patients may be a manifestation of metabolic disorders, and has a certain correlation with routine laboratory indicators, which is worthy of the attention from clinicians.     

Gender effect on eating habits of Nigerian school children

It is important to investigate children''s eating habits based on different eating behaviors such as satiety responsiveness (SR), slowness in eating (SE), food fussiness (FF), food responsiveness (FR), enjoyment of food (EF), desire to drink (DD), emotional under-eating (EUE), and emotional over-eating (EOE). The main objective of this research was to investigate whether gender affects the eating habits of Nigerian school children.A cross-sectional survey was conducted between March and June 2019. A total of 120 parents of school children participated in the study. The Child Eating Behavior Questionnaire (CEBQ) was used to collect data. The CEBQ is composed of 35 items and eight subscales.Based on the analysis of parents’ reports, DD was higher in boys than girls, t (118) = 7.086, P < .001; EOE was higher in boys than girls, t (118) = 5.184, P < .001; EF was higher in boys than girls, t (118) = 2.183, P < .001; FF was higher in boys than girls, t (118) = 9.441, P < .001; and SR was higher in boys than girls, t (118) = 7.323, P < .001. However, EUE was lower in boys than girls, t (118) = −4.339, P < .001; FR was lower in boys than girls, t(118) = −3.112, P < .001; SE was lower in boys than girls, t(118) = −3.832, P < .001; thus, gender had a significant influence on eating habits of the school children.Gender significantly affects the eating habits of Nigerian school children. Thus, gender is an important factor to be considered when aiming to improve the eating habits of Nigerian school children.     

Study on the preventive effect of intravenous esomeprazole in the management of nonvarices upper gastrointestinal bleeding

This retrospective study investigated the preventive effect of intravenous esomeprazole (IVEO) in the prevention of nonvarices upper gastrointestinal bleeding (NUGIB).This study enrolled 130 patients with NUGIB and all of them underwent successful endoscopic hemostasis, of which 65 cases received routine management and IVEO (Group A) and the other 65 cases received routine management alone (Group B). The primary outcome (recurrent bleeding rate within 72-hour, 7-day, and 30-day), and secondary outcomes ((all-cause mortality, bleeding-related mortality, blood transfused, hospital stay (day), and incidence of adverse events)) were compared between 2 groups.Patients in the group A showed lower recurrent bleeding rate within 72-hour(P < .05), 7-day (P < .05), and 30-day (P < .05), than that of patients in the group B. However, no significant differences were identified in all-cause mortality(P = .26), bleeding-related mortality (P = .57), blood transfused (P = .33), and hospital stay (P = .74) between 2 groups. In addition, both groups had similar safety profile.This study found that routine management and IVEO was superior to the routine management alone for preventing the recurrent bleeding rate after successful endoscopic hemostasis in patients with NUGIB.     

The high expression of CHD1L and its clinical significance in human solid tumors: A meta-analysis

Background:Chromodomain helicase DNA-binding protein 1-like (CHD1L) is an oncogene. It was cloned from 1q21 chromosome region of hepatocellular carcinoma in 1991. CHD1L is up-regulated in many kinds of cancers and is involved in the carcinogenesis and development of tumors. More and more studies have shown that over-expression of CHD1L is associated with poor prognosis of tumors. The purpose of this study was to evaluate the prognostic value of CHD1L in human solid tumors.Methods:The key words in the database of PubMed, Web of Science, Embase, Cochrane library, and TCGA were searched for systematic literature retrieval. We collected relevant articles and data about CHD1L and prognosis of cancer and screened them according to the eligible criteria to evaluate the prognostic value of CHD1L in cancer patients. Then Stata SE12.0 software is used to analyze the data.Results:In our meta-analysis, 2720 patients with a total of 15 articles involving multiple types of tumors showed that high expression levels of CHD1L were associated with shorter overall survival (OS) (hazard ratio  = 2.21, 95% confidence interval [CI]: (1.49–3.30)] and (hazard ratio  = 1.16, 95% CI: (1.01–1.32)] in the TCGA database, in addition, the pooled odds ratios (ORs) indicated high expression levels of CHD1L in tumors significantly are associated with TNM stage (OR = 1.61, 95% CI: 1.01–2.55, P < .05), tumor size (OR = 1.38, 95% CI: 1.07–1.78, P < .05), tumor differentiation (OR = 2.13, 95% CI: 1.43–3.16, P < .05), and distant metastasis (OR = 1.86, 95% CI: 1.45–2.39 P < .05). However, we did not observe a significant correlation between the high expression of CHD1L and age, gender.Conclusion:The high expression of CHD1L is associated with poor OS as well as related to tumor differentiation, tumor size, and distant metastasis, which can be served as a prognostic marker and a potential predictor of clinical pathology in human solid tumors.     

Clinical outcomes in acute pancreatitis with relative bradycardia at fever onset

While some acute pancreatitis (AP) patents with fever do not exhibit a corresponding increase in heart rate, the clinical significance of this phenomenon has not been studied. We investigated the clinical relevance of relative bradycardia (RB) in febrile AP.A retrospective electronic chart review was conducted on consecutive patients admitted for AP at a tertiary referral center in Japan from January 1, 2010, to May 31, 2018. Presence of RB was determined at the first instance of fever, based on formulas used in previous studies.Fever at or during admission was observed in 115 patients, of which 33% had RB. Fever was observed at presentation in 48% and within 48 hours in 94% of cases. Etiologies were alcoholic in 48% and gallstones in 17% of cases. RB patients were older (median age: 62 vs 51 years, P = .028) but had shorter median postfever lengths of stay (8 vs 12 days, P = .003), lower median Ranson scores (1 vs 2, P < .001), and were less likely to develop delirium (11% vs 38%, P = .002). Nineteen of 21 severe AP cases based on the Ranson score were nonbradycardia (P = .011). RB was also associated with lower white blood cell count, C-reactive protein, and lactate levels. On computed tomography, necrosis (P = .028) and moderate or severe pancreatitis (P = .041) were less frequently observed in patients with RB. There was a significant inverse correlation between RB and the Ranson score (−.305, P = .001). While RB was an independent predictors of postfever length of stay (LOS) in multiple regression analysis when the Ranson score was excluded (P = .010), it ceased to be significant when the Ranson score was included (P = .141).AP patients with RB at fever onset had milder disease and shorter LOS compared to those with higher heart rates at fever onset. RB may be useful as a simple, early predictor of shorter LOS before the Ranson score can be calculated.     

Beneficial effects of Aloe ferox on lipid profile,blood pressure,and glycemic control in obese persons: A CONSORT-clinical study

Background:Aloe ferox is one of the most widely used medicinal plants today, with the most intense detoxifying action of all aloe species, being used in the treatment of various diseases, including obesity. Our study aimed to assess the efficacy of Aloe ferox in obesity treatment.Methods:The study sample included 20 Romanian persons with obesity treated with diet and Aloe ferox based supplements, and 20 Romanian matched controls treated with diet and a placebo. The treatment included 2 capsules/day (Aloe ferox 460 mg) for 2 weeks, followed by a 2-week break, repeated 3 times. The blood pressure (systolic and diastolic) and anthropometric parameters, such as body mass index (BMI), total cholesterol, and abdominal circumference, as well as the biochemical parameters, fasting blood glucose (FBG), uric acid, and lipid profile was evaluated at baseline and after 3 months.Results:After 3 months of Aloe ferox administration, significant differences between the study group and the control group were observed regarding BMI (P = .03), total cholesterol (P = .032), low-density lipoprotein cholesterol (LDLc) (P = .01) and FBG (P = .018). Also, between the initial clinical, anthropometric, and biological parameters and those after the administration of Aloe ferox in the study group, we obtained significant differences regarding BMI (P = .002), LDLc (P = .039), fasting glycemia (P < .001) and diastolic blood pressure (P = .006).Conclusions:The administration of Aloe ferox to obese patients has been shown to achieve a significant reduction in body weight, BMI, LDLc, and FBG. These effects may be due to the laxative and detoxifying action of Aloe ferox components. As it can only be administered for limited periods due to side effects, further experimental and human studies of the efficacy of this plant in the treatment of obesity are needed.     

The effect of binaural beat audio on anxiety in patients undergoing fiberoptic bronchoscopy: A prospective randomized controlled trial

Background:Fiberoptic bronchoscopy is an invasive procedure known to induce anxiety in patients. Binaural beat therapy, in which sounds of different frequencies are delivered to the 2 ears to entrain the brainwaves, has been used to reduce anxiety in some operations. This study aimed to determine the anxiolytic effects of binaural beat audio in patients undergoing fiberoptic bronchoscopy.Methods:Eligible subjects were randomly assigned to receive binaural beat music, plain music, or no music. They were asked to wear earphones starting approximately 15 minutes before the bronchoscopy. The level of anxiety was measured using the State-Trait Anxiety Inventory questionnaire. Blood pressure, heart rate, and sedative drug administration were also recorded.Results:One hundred and twelve subjects were randomized into binaural beat music (n = 38), plain music (n = 38), and no music (n = 36) groups. The mean change in post-bronchoscopy State-Trait Anxiety Inventory state score in the binaural beat music, plain music, and no music group was −7.26 (P < .001), −3.92 (P = .005), and −1.12 (P = .454), respectively. The mean systolic blood pressure and diastolic blood pressure significantly decreased from baseline by −9.89 (P = .002) and −5.76 (P = .005), respectively, in the binaural group. The mean heart rate increased from baseline by 3.32 (P = .035), 5.21 (P = .038), and 3.64 (P = .149) in the binaural beat music, plain music, and no music groups, respectively.Conclusion:Binaural beat music appeared to reduce anxiety among patients undergoing fiberoptic bronchoscopy.Trial registration: TCTR, TCTR20200915002. Registered 14 September 2020 - Retrospectively registered.     

Effects of individualized administration of folic acid on prothrombotic state and vascular endothelial function with H-type hypertension: A double-blinded,randomized clinical cohort study

Background:Hypertension and hyperhomocysteinemia (HHcy) have long been associated with adverse cardiovascular and cerebrovascular health outcomes. This study evaluated the effect of individualized administration of folic acid (FA) on homocysteine (Hcy) levels, prothrombotic state, and blood pressure (BP) in patients with H-type hypertension (combination of HHcy and hypertension).Methods:In this double-blinded, randomized clinical cohort study, 126 patients with H-type hypertension who were treated at our hospital were randomly divided into treatment and control groups (n = 55 each). The control group was treated with oral levamlodipine besylate tablets 2.5 mg and placebo, once a day (in the morning). The treatment group was first treated with oral levamlodipine besylate 2.5 mg and FA tablets 0.8 mg, once a day (in the morning), for 12 weeks. Then, in a second 12-week phase, the FA dose was adjusted using the methylene tetrahydrofolate reductase C677 polymorphism genotype. The levels of Hcy and coagulation factors, prothrombotic state parameters, BP, and adverse drug reactions were compared between the 2 groups.Results:Pretreatment general patient characteristics, including Hcy levels, were similar between the 2 groups (P > .05). BP and prothrombotic status did not differ before and after the first phase of treatment (P > .05). However, Hcy and endothelin-1 (ET-1) levels decreased, while nitric oxide levels increased significantly in the intervention group (P < .05). In the second phase, after 3 months’ treatment with an FA dose adjusted according to methylene tetrahydrofolate reductase C677T genotype, the Hcy and ET-1/NO levels were significantly decreased in the intervention group and were lower than those after the first treatment phase and lower than in the control group (P < .01). BP, D-dimer levels, and fibrinogen scores were significantly lower after the second treatment phase (P < .01). There was no significant difference in the incidence of adverse drug reactions between the 2 groups (P > .05).Conclusions:Individualized administration of FA tablets can effectively reduce BP, and Hcy and coagulation factor levels, and significantly improve prothrombotic status in patients with H-type hypertension.     

Invaginated duct to mucosa pancreaticojejunostomy reduce postoperative pancreatic leakage: A matched case-controlled study

Postoperative pancreatic leakage is an obstacle in pancreaticoduodenectomy, which always follows pancreaticojejunostomy (PJ) failure. Dozens of PJ procedures have been reported, and none have shown superiority over others. Therefore, the present study is conducted to assess the potential advantages of invaginated duct-to-mucosa (D-M) PJ.We retrospectively analyze the related data from patients who underwent pancreaticodedunostomy due to malignant tumors at the First Affiliated Hospital of Henan University of Science and Technology from January 2017 to August 2019. According to the different PJ procedures, the patients are divided into custom D-M group and invaginated D-M group. Matching by sex, age, pancreatic duct size, and pancreatic texture is performed. Pancreatic leakage and other complications are compared, and SPSS 16.0 is employed for analysis.A total of 48 pairs of patients are included. Patients in both groups has almost the same baseline characteristics in terms of sex (P = 1.000), age (P = .897), American Society of Anesthesiologists status (P = .575), body mass index (P = .873), pancreatic duct size (P = .932), pancreatic texture (P = 1.000) and tumor origin (P = .686). No significant difference is observed in operative outcomes, such as operative duration (P = .632), PJ duration (P = .748), blood loss (P = .617) and number of required transfusions (P = .523). Pancreatic leakage is significantly decreased in the invaginated D-M group (P = .005). The differences in other complications, such as bleeding (P = .617), biliary leakage (P = .646), pneumonia (P = .594) and thrombosis (P = .714), do not reach statistical significance. The postoperative hospitalization duration is almost the same for both groups (P = .764).Invaginated D-M PJ may reduce pancreatic leakage following pancreaticoduodenectomy.     

Susceptibility of ABO blood group to COVID-19 infections: clinico-hematological,radiological, and complications analysis

In the wake of the COVID-19 pandemic, research indicates that the COVID-19 disease susceptibility varies among individuals depending on their ABO blood groups. Researchers globally commenced investigating potential methods to stratify cases according to prognosis depending on several clinical parameters. Since there is evidence of a link between ABO blood groups and disease susceptibility, it could be argued that there is a link between blood groups and disease manifestation and progression. The current study investigates whether clinical manifestation, laboratory, and imaging findings vary among ABO blood groups of hospitalized confirmed COVID-19 patients.This retrospective cohort study was conducted between March 1, 2020 and March 31, 2021 in King Faisal Specialist Hospital and Research Centre Riyadh and Jeddah, Saudi Arabia. Demographic information, clinical information, laboratory findings, and imaging investigations were extracted from the data warehouse for all confirmed COVID-19 patients.A total of 285 admitted patients were included in the study. Of these, 81 (28.4%) were blood group A, 43 (15.1%) were blood group B, 11 (3.9%) were blood group AB, and 150 (52.6%) were blood group O. This was almost consistent with the distribution of blood groups among the Saudi Arabia community. The majority of the study participants (79.6% [n = 227]) were asymptomatic. The upper respiratory tract infection (P = .014) and shortness of breath showed statistically significant differences between the ABO blood group (P = .009). Moreover, the incidence of the symptoms was highly observed in blood group O followed by A then B except for pharyngeal exudate observed in blood group A. The one-way ANOVA test indicated that among the studied hematological parameters, glucose (P = .004), absolute lymphocyte count (P = .001), and IgA (P = .036) showed statistically significant differences between the means of the ABO blood group. The differences in both X-ray and computed tomography scan findings were statistically nonsignificant among the ABO age group. Only 86 (30.3%) patients were admitted to an intensive care unit, and the majority of them were blood groups O 28.7% (n = 43) and A 37.0% (n = 30). However, the differences in complications’ outcomes were statistically nonsignificant among the ABO age group.ABO blood groups among hospitalized COVID-19 patients are not associated with clinical, hematological, radiological, and complications abnormality.     

The clinical profiles,management, and prognostic factors of biliary mixed neuroendocrine nonneuroendocrine neoplasms: A systematic review of the literature

Background:Mixed neuroendocrine nonneuroendocrine neoplasms (MiNENs) originating from the biliary system (gallbladder, biliary tract, or ampulla of Vater) are extremely rare and have not been discussed in detail or systematically. We aimed to present the demographics, clinicopathological characteristics, management, and prognostic factors of biliary MiNENs.Methods:A systematic search of electronic biomedical databases (Web of Science, PUBMED, and Embase) was performed to identify eligible studies. Survival was analyzed with the Kaplan–Meier method. Log-rank tests were used to evaluate the differences between groups, and the effects of various clinical and histopathological features on prognosis were analyzed by univariate and multivariate Cox regression.Results:Fifty-three publications (patients, n = 67) were included. The median overall survival time was 21.0 months. Fifty-one patients (76.1%) underwent radical surgery and median survival for 41 months (P < .001). Twenty-two patients who received adjuvant radiochemotherapy treatment after radical surgery had a median survival for 43 months (P = .076). Radical resection (P < .001), Ki-67 index (P = .011), tumor stage (P < .001), neuroendocrine (NEC) grade (P = .011), and non-NEC grade (P = .017) were independent statistically significant prognostic factors according to univariate analysis; radical resection (P = .010) and small morphological subtype (P = .036) were independent statistically significant prognostic factors associated with higher overall survival according to multivariate analysis, and radical resection (P = .005) and age < 65 years (P = .026) were associated with higher recurrence free survival time.Conclusion:Radical resection is essential for long-term survival. Aggressive multimodality therapy with adjuvant radiochemotherapy and biotherapy may improve survival of biliary MiNENs. Further randomized controlled trials are needed to determine the standard treatment.     

Assessment of cerebrovascular reserve with N-isopropyl-p-[123I]-iodoamphetamine time series analysis in patients with cerebrovascular disease

Using N-isopropyl-p-[¹²³I]-iodoamphetamine(¹²³I-IMP) and single-photon emission computed tomography (SPECT), the relationship between cerebrovascular reserve and the ¹²³I-IMP redistribution phenomenon was investigated.The 50 patients who matched the inclusion criteria were divided into control and ischemia groups, and the redistribution phenomenon was examined on resting images. The delayed images showed higher ¹²³I-IMP accumulation in lesions in the middle cerebral artery(MCA) area and anterior cerebral artery(ACA) area, these watershed areas in the ischemia group than in the control group, confirming that the redistribution phenomenon exists with statistical significance (Wilcoxon test; control group vs ischemic group in the ACA area[P = .002], ACA-MCA watershed area(P = .014), MCA area(P = .025), and MCA-posterior cerebral artery(PCA) watershed area(P = .002). The patients were then divided into 4 types according to the Kuroda grading system, and the difference in the redistribution phenomenon was investigated between type III and the other 3 types.Compared with type I and type II, type III had a significantly lower rate of decrease in the radioisotope (RI) count, verifying the redistribution phenomenon (Student t test: type I vs type III in the ACA area(P = .008), ACA-MCA watershed area(P = .009), MCA area(P < .001), and MCA-PCA watershed area(P = .002); type II vs type III in the ACA area(P = .004), ACA-MCA watershed area(P = .2575), MCA area(P < .001), and MCA-PCA watershed area(P < .001). No significant difference between type III and type IV was observed in any area [(Student t test: type III vs type IV in the ACA area(P = .07), ACA-MCA watershed area(P = .38), MCA area(P = .05), and MCA-PCA watershed area(P = .24)].The redistribution phenomenon is associated with resting cerebral blood flow (CBF), but not necessarily with cerebral vascular reactivity (CVR).
