Factors Associated with Non-Adherence to Treatment in Sickle Cell Patients Monitored at the National Reference Center for Sickle Cell Disease in Niger

Introduction: Sickle cell disease is a real public health problem in the world and particularly in Niger where the prevalence of the S gene is estimated at 25% and that of the homozygous forms at between 1% and 2%. Treatment combines quarterly follow-up of patients and management of complications. The objective of this study was to identify the potential explanatory factors of non-adherence to treatment in sickle cell patients followed at the national reference center for sickle cell disease in Niger. Methods: This is a cross-sectional study of sickle cell cases followed at the CNRD in Niger. The population consisted of all sickle cell patients followed in this center in 2021. The data collection techniques were individual interviews and documentary reviews. Non-adherence was assessed with the Girerd test. Descriptive statistical tests and simple and multiple logistic regression models were performed. Results: A total of 368 patients were enrolled. The median age is 7 years (4;10) and the sex ratio is 1.04. Ninety-eight (98) or 26.6% were compliant and 270 (73.4%) were non-compliant. In multivariate analysis, the factors independently and negatively associated with non-adherence to treatment were schooling (adjusted OR [95% CI], p-value), 0.17 [0.10 - 0.30];p Conclusion: The factors influencing treatment compliance identified in this study are all modifiable. To prevent the complications of sickle cell disease, we must fight against ignorance, make care services accessible and make care free.

Non-viral factors contributing to hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a major cause of cancer death worldwide, accounting for over half a million deaths per year. The geographic pattern of HCC incidence is parallel to exposure to viral etiologic factors. Its incidence is increasing, ranging between 3% and 9% annually depending on the geographical location, and variability in the incidence rates correspond closely to the prevalence and pattern of the primary etiologic factors. Chronic infections with hepatitis B viruses or hepatitis C viruses have both been recognized as human liver carcinogens with a combined attributable fraction of at least 75% of all HCC cases. Multiple non-viral factors have been implicated in the development of HCC. Increased body mass index and diabetes with subsequent development of non-alcoholic steatohepatitis represent significant risk factors for HCC. Other non-viral causes of HCC include iron overload syndromes, alcohol use, tobacco, oral contraceptive, aflatoxin, pesticides exposure and betel quid chewing, a prevalent habit in the developing world. Wilson disease, α-1 antitrypsin deficiency, Porphyrias, autoimmune hepatitis, Schistosoma japonicum associated with positive hepatitis B surface antigen, and thorotrastray are also contributing hepatocellualar carcinoma. In addition, primary biliary cirrhosis, congestive liver disease and family history of liver cancer increase the risk of HCC incident. In conclusion,clarification of relevant non-viral causes of HCC will help to focus clinicians on those risk factors that are modifiable. The multilevel preventative approach will hopefully lead to a reduction in incidence of non-viral HCC, and a decrease in the patient morbidity and mortality as well as the societal economic burden associated with HCC.

Clustering of Non-communicable Diseases Risk Factors in Healthy Adults Aged 35 Years and Older in Shenzhen,China

We assessed the prevalence of non‐ communicable diseases（NCDs） risk factors with a focus on their clustering among healthy adults in Shenzhen, China. Data from the 2011 China Health and Nutrition Survey, comprising a regionally representative sample of 806 healthy adults aged 35 years or older, were obtained to determine the prevalence of five risk factors for NCDs. The prevalence of current smoking, central obesity, impaired fasting glucose, borderline hypertension, and borderline high total cholesterol was 19.97%, 28.29%, 4.47%, 10.55%, and 36.10%, respectively. A total 63.77% of participants had at least one risk factor. Upon examination of risk factor clustering, we observed that 7.57% of participants had at least three risk factors. Using this threshold as a cutoff, clustering of risk factors was associated with sex [odds ratio（OR） = 3.336, 95% confidence interval（CI）： 1.782 to 6.246], physical activity（OR = 1.913, 95% CI： 1.009 to 3.628）, and BMI（OR = 7.376, 95% CI： 3.812 to 14.270）. The prevalence of risk factors for NCDs is fairly high among healthy adults in Shenzhen, with a clustering tendency.

Prevalence of and risk factors for non-alcoholic fatty liver disease in a Chinese population: An 8-year follow-up study

AIM: To investigate the prevalence of and risk factors for non-alcoholic fatty liver disease(NAFLD) in a Chinese population.METHODS: A total of 1948 adults from China was followed for 8 years. A cross-sectional study was performed to investigate the prevalence of NAFLD at baseline, and then the participants were followed for 8 years to investigate risk factors for the development of NAFLD.RESULTS: A total of 1948 participants were enrolled at baseline, of whom 691 were diagnosed with NAFLD. During the 8-year follow-up, 337 baseline NAFLD-free participants developed NAFLD. They had a greaterincrease in body mass index(BMI), serum uric acid, fasting plasma glucose, very low-density lipoprotein cholesterol and a considerable decrease in high-density lipoprotein cholesterol. 123 participants who had NAFLD at baseline lost NAFLD during the 8-year follow-up period. They had a greater decrease in BMI, fasting plasma glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, and γ-glutamyl transpeptidase.CONCLUSION: NAFLD is prevalent in Chinese population with a rapidly increasing tendency. It can be reversed when patients lose their weight, control their hyperlipidemia and hyperglycemia, and reduce the liver enzyme levels.

Risk factors for proton pump inhibitor refractoriness in Chinese patients with non-erosive reflux disease

AIM:To analyze risk factors for refractoriness to proton pump inhibitors(PPIs) in patients with non-erosive reflux disease(NERD).METHODS:A total of 256 NERD patients treated with the PPI esomeprazole were enrolled.They were classified into symptom-free and residual symptoms groups according to Quality of Life in Reflux and Dyspepsia(QolRad) scale.All subjects completed questionnaires on psychological status(self-rating anxiety scale;selfrating depression scale) and quality of life scale(Short Form 36).Multivariate analysis was used to determine the predictive factors for PPI responses.RESULTS:According to QolRad,97 patients were confirmed to have residual reflux symptoms,and the remaining 159 patients were considered symptom free.There were no significant differences between the two groups in lifestyle factors(smoking and alcohol consumption),age,Helicobacter pylori infection,and hiatal hernia.There were significant differences between the two groups in relation to sex,psychological distress including anxiety and depression,body mass index(BMI),and irritable bowel syndrome(IBS)(P < 0.05).Logistic regression analysis found that BMI < 23,comorbid IBS,anxiety,and depression were major risk factors for PPI resistance.Symptomatic patients had a lower quality of life compared with symptom-free patients.CONCLUSION:Some NERD patients are refractory to PPIs and have lower quality of life.Residual symptoms are associated with psychological distress,intestinal disorders,and low BMI.

Risk factors of gastroparesis syndrome after abdominal nongastroduodenal operation and its prevention

Objective:To investigate risk factors of gastroparesis syndrome(PGS) after abdominal nongastroduodenal operation and its prevention.Methods:Clinical data of 22 patients with PGS after abdominal non-gastroduodenal operation was analyzed retrospectively,and compared with the patients of non-PGS after abdominal non-gastroduodenal operation during the same time.The possible influencing factors of PCS were analyzed by single factor analysis and logistic regression analysis.Results:All t3 selected factors related with PGS,including age,disease category (benign and malignant),operation time,intraoperative blood loss,postoperative analgesic pump, postoperative enteral nutrition time,postoperative parenteral nutrition time,perioperative blood glucose level,perioperative nutrition status(anaemia or lower proleinemia),pylorus obstruction before surgery,intra-abdominal infection after surgery,and spiritual factor were related with PGS.The statistical analysis showed that the difference was statistical significant(P【0.05),and gender had no correlation with PCS(P】0.05);non-conditional multivariate analysis showed that malignant tumor,perioperative nutrition status,pylorus obstruction,operation time,blood loss, intra-abdominal infection after surgery,and mental factor were significant related with PGS as dependent variable and related risk factors in single factor analysis as independent variables (P 【0.05).Conclusions:PGS is a result of multiple factors,and among these factors,malignant tumor,poor nutrition status,pylorus obstruction before surgery,longer operation—time,more blood loss,intra-abdominal infection after surgery,and mental factor are major risk factors of PGS.

New insights of Helicobacter pylori host-pathogen interactions: The triangle of virulence factors, epigenetic modifications and non-coding RNAs

Helicobacter pylori(H. pylori) is a model organism for understanding host-pathogen interactions and infection-mediated carcinogenesis. Gastric cancer and H. pylori colonization indicates the strong correlation. The progression and exacerbation of H. pylori infection are influenced by some factors of pathogen and host. Several virulence factors involved in the proper adherence and attenuation of immune defense to contribute the risk of emerging gastric cancer, therefore analysis of them is very important. H. pylori also modulates inflammatory and autophagy process to intensify its pathogenicity. From the host regard, different genetic factors particularly affect the development of gastric cancer. Indeed, epigenetic modifications, Micro RNA and long non-coding RNA received more attention. Generally, various factors related to pathogen and host that modulate gastric cancer development in response to H. pylori need more attention due to develop an efficacious therapeutic intervention. Therefore, this paper will present a brief overview of host-pathogen interaction especially emphases on bacterial virulence factors, interruption of host cellular signaling, the role of epigenetic modifications and non-coding RNAs.

Correlation between non-alcoholic fatty liver with metabolic risk factors and brachial-ankle pulse wave velocity

AIM: To assess the relationship between non-alcoholic fatty liver disease(NAFLD) with metabolic risk factors and brachial ankle pulse wave velocity(ba PWV). METHODS: A total of 8603 subjects(6662 males and 1941 females) were enrolled during an annual health check-up. Fatty liver was examined using a Philips HD 11 XE multi-function color Doppler diagnostic instrument, and ba PWV was determined using a novel arteriosclerosis detection device. Blood pressure(BP), fasting plasma glucose(FPG), waist circumference( W C), p l a s m a t r i g l y c e r i d e s( TG), h i g h- d e n s i t y lipoprotein(HDL), total cholesterol(TC), low-density lipoprotein(LDL) and uric acid(UA) were measured using standard methods. The relationship between fatty liver with metabolic risk factors and ba PWV was analyzed using regression analysis and the χ2 test. RESULTS: The values and abnormal rates of ba PWV were significantly different between NAFLD patients and non-NAFLD subjects(P < 0.001). In addition, the values of ba PWV were different by gender between NAFLD patients and non-NAFLD subjects. The OR values in females, males, and the entire population were 3.33, 1.67, and 2.13, respectively(P < 0.001). The incidence of high ba PWV increased with increasing degree of NAFLD(levels 0, 1, 2, and 3)(P < 0.001), which was 45.9%, 54.5%, 60.2%, and 71.4% in malesand 27.0%, 49.1%, 55.60%, and 60.0% in females(P < 0.001), respectively. Logistic regression analysis showed that the OR value for ba PWV in the nonmetabolic syndrome group and the metabolic syndrome group was 1.28 vs 1.14(males) and 2.55 vs 0.98(females). The OR values for ba PWV in the non-high-BP and high-BP, non-high-WC and high-WC, non-high-FPG and high-FPG, non-high-TG and high-TG, non-high-HDL and high-HDL, non-high-TC and high-TC, non-high-LDL and high-LDL, non-high-UA and high-UA groups were 3.38 vs 1.19, 3.50 vs 1.44, 2.80 vs 2.30, 3.29 vs 1.88, 3.03 vs 3.28, 3.35 vs 2.70, 3.93 vs 1.66, and 3.20 vs 2.34, respectively, in females(P < 0.001), and were 1.37 vs 1.34, 1.56 vs 1.26, 1.51 vs 1.28, 1.49 vs 1.52, 1.71 vs 1.61, 1.59 vs 1.74, 1.76 vs 1.47, and 1.73 vs 1.54, respectively, in males(P < 0.01). The OR value for ba PWV was still higher than 1.2(1.21 in males and 1.40 in females) after adjustment for the metabolic component(0, 1, 2, 3, 4, 5, 6 and above)(P < 0.01).CONCLUSION: NAFLD is closely correlated with ba PWV, particularly in females. NAFLD has a large impact on ba PWV, no matter whether the metabolic index is increased or not. NAFLD may be a useful indicator for assessing early arteriosclerosis.

Survival and prognostic factors of non-small cell lung cancer patients with postoperative locoregional recurrence treated with radical radiotherapy

Background: Locoregional recurrence remains the challenge for long-term survival of non-small cell lung cancer(NSCLC) patients after radical surgery, and curative-intent radiotherapy could be a treatment choice. This study aimed to assess the survival and prognostic factors of patients with postoperative locoregionally recurrent NSCLC treated with radical radiotherapy.Methods: We reviewed medical records of 74 NSCLC patients with postoperative locoregional recurrence who received radical radiotherapy between April 2012 and February 2016 at Sun Yat-sen University Cancer Center(Guangzhou, China). The efficacy and safety of radical radiotherapy were analyzed. The probability of survival was estimated using the Kaplan-Meier method and compared using the log-rank test. The Cox proportional hazards model was used to identify prognostic factors.Results: Grade 3/4 adverse events included neutropenia(8 cases, 10.8%), esophagitis(7 cases, 9.5%), pneumonitis(1 case, 1.4%), and vomiting(1 case, 1.4%).The 2-year overall survival, progression-free survival, local recurrencefree survival(LRFS), and distant metastasis-free survival(DMFS) rates of all patients were 84.2,42.5,70.0, and 50.9%,respectively. Univariate and multivariate analyses showed that a higher biological effective dose(BED) of radiation was associated with longer LRFS [hazard ratios(HR)=0.317,95% confidence interval(CI) = 0.112-0.899, P = 0.016] and that wild-type epidermal growth factor receptor(EGFR) was associated with longer DMFS compared with EGFR mutation(HR = 0.383,95% CI=0.171-0.855, P = 0.019).Conclusions: Radical radiotherapy is effective and well-tolerated in NSCLC patients with postoperative locoregional recurrence. High BED is a predictor for long LRFS, and the presence of wild-type EGFR is a predictor for long DMFS.

Effects of Size Grading on Growth and Non-Specific Immunity Factors of the Shrimp Litopenaeus vannamei Boone

The study aims to determine the effects of graded farming on growth performance and non-specific immunity factors of shrimp Litopenaeus vannamei Boone. Three size groups of shrimp, i.e., the small size group [Gs, with an average body length （BL） of （3.04 ± 0.36） cm and body weight （BW） （0.412± 0.35） g], the large group [GL, with a BL of （4.29±0.55） cm and BW of （1.098 ±0.42） g], and the ungraded group [Gm, with a BL of （3.47±0.81） cm and BW of （0.611 ±0.79） g], were reared under the same conditions for 8 wk. Growth performance and non- specific immunity factors were measured. The results showed that BW gain, biomass gain and the specific growth rate of body length （SGRL） were significantly influenced by size grading （one-way ANOVA, P 〈 0.05）. The peroxidase （POD） and antibacterial （Ua） activities of GL were lower than those of G. Superoxide dismutase （SOD） and lysozyme （U1） activities of Gm were lower than those of G. No significant difference （P = 0.121 〉 0.05） was found on phenoloxidase （PO） activity among the three size groups. Synthetically, size grading could enhance growth and rearing efficiency, and did not have a significant influence on the immunity of L. vannamei Boone. Therefore, graded fanning in L. vannamei Boone was feasible in the culture practice.

Predictive factors associated with gefitinib response in patients with advanced non-small-cell lung cancer(NSCLC)

Purpose： A number of different clinical characteristics have been reported to singly correlate with therapeutic activity of epidermal growth factor receptor （EGFR） tyrosine kinase inhibitors （TKIs） in advanced non-small-cell lung cancer （NSCLC）. This study aimed to identify predictive factors associated with prognostic benefits of gefitinib. Patients and methods： EGFR gene typing in 33 advanced NSCLC patients received gefitinib （250 mg/day） were analyzed with mutant-enriched PCR assay. Gefitinib response was evaluated with potential predictive factors retrospectively. Results： The overall objective response rate （ORR） and median progression-flee survival （PFS） in the 33 patients treated by gefitinib were 45.5% and 3.0 （2.0-4.0） months. The ORR and median PFS in EGFR gene mutation patients were significantly higher/longer than those in EGFR gene wild-type patients （P〈0.01）. Similarly, the ORR and median PFS in non-smoker patients were significantly higher/longer than those in smoker patients （P〈0.05, P〈0.01, respectively）. However, no difference for ORR and median PFS occurred between male and female patients. Logistic multivariate analysis showed that only EGFR mutated gene was significantly associated with the ORR （P〈0.01）. Both EGFR mutated gene and non-smoker were the major factors that contributed to PFS （P〈0.05）. Conclusions： EGFR mutated gene and non-smoker status are potential predictors for gefitinib response in NSCLC patients.

Prevalence of Circadian Blood Pressure Patterns and Factors Associated with Non-Dipping among Black Patients with Untreated and Treated Hypertension: A Cross-Sectional Study

Objective: To determine the prevalence of circadian BP patterns and to assess factors associated with the non-dipping pattern in untreated and treated hypertensive patients, studied separately. Methods: Clinical data and ABPM were obtained from 52 untreated and 168 treated hypertensive patients referred for ABPM to Monkole Hospital in Kinshasa. Twenty-four ABPM was performed using an oscillometric device. Non-dipping pattern encompasses non-dipping (nocturnal systolic BP dip less than 10% of daytime systolic BP) and reverse dipping (mean night SBP higher than the day SBP). Results: the prevalence of non-dipping pattern was 75% (63.5% non-dipping and 11.5% reverse dipping) and 70% (60.1% non-dipping and 10.1% reverse dipping) in untreated and treated hypertensive patients, respectively. Advanced age (adjusted OR 1.80;95%CI 1.96 - 3.38;p = 0.015), female sex (adjusted OR 2.28;95%CI 1.19 - 4.36;p = 0.013), diabetes (adjusted OR 5.06;95%CI 1.38 - 6.95;p = 0.014), reduced kidney function (adjusted OR 3.10;95%CI 1.50 - 6.43;p = 0.018), inflammation (adjusted OR 2.65;95%CI 1.76 - 6.48;p = 0.031), LVH (adjusted OR 4.45;95%CI 1.78 - 7.67;p = 0.024) and antihypertensive therapy (adjusted OR 0.19;95%CI 0.12 - 0.64;p = 0.018) emerged as the main independent factors significantly associated with the non-dipping pattern in the study population. Conclusion: the non-dipping pattern was a common finding in studied patients and associated with traditional and emerging risk factors suggesting that this abnormal pattern could be a marker of high cardiovascular risk.

Do parental coronary heart disease risk factors(non-modifiable) effect their young ones?

Objective:To study the differences between the lipid profiles of the subjects whose parents are having known non-modifiable risk factors such as obesity,hypertension(HTN),myocardial infarction and diabetes,and compare them with the lipid profiles of the subjects whose parents are not having those risk factors.Methods:A total of 402 subjects were recruited to this study.A detailed questionnaire which included information on the past medical history,height,weight,blood pressure,physical activity,smoke,alcohol,family history of coronary heart disease,HTN.diabetics and obesity.Basic demographic data and dietary habits were completed by all participants.Blood samples were obtained from all subjects after 14 h.Lipid profiles were analyzed using automated analyzer.The results were analyzed using SPSS software packages.Results:The mean body mass index of the population was well below the cut-off value of obesity(>24.5 kg/m") and high risk of future cardiovascular disorder(CVD) events in this age group.The mean levels of total cholesterol(TC),triglycerides(TG) and TC/high density lipoprotein(HDL) were less than the risk levels indicative of future CVD events according to the ATP Ⅲ cut-off values.However the mean HDL level in our population was slightly greater than the cut-off value while the mean low density lipoprotein level was almost similar to the risk level.Differences were observed when the subjects without history of maternal obesity were compared with subjects with history of maternal obesity.The greater percentage of subjects who are having risk levels of body mass index.TC.low density lipoprotein.TG.and TC/HDI.indicated that maternal obesity contributed to the greater susceptibility of developing CVD risk in their offspring.Conclusions:Advancing age may result in changes that could be atherogenic in the future.Such atherogenic changes have already initialed when the subjects are about 21 years old.The incidence of atherogenic changes is far greater when mothers who are having any of the risk factors such as obesity,diabetes,HTN and myocardial infarction than that fathers who are havine similar risk factors.

Prognostic factors for pN2 non-small cell lung cancer:a comprehensive evidence from 73 studies involving 23,772 patients

Obojective Non-small-cell lung cancer(NSCLC)is a common malignancy.pN2 NSCLC,with pathologically confirmed ipsilateral mediastinal/subcarinal nodes metastasis,has been known as a very heterogeneous subgroup in terms of its anatomical,biological and patient characteristics.Prognostic factors based on patient characteristics were not well determined yet in this subgroup,and there is currently no standard treatment recommendation for these heterogeneous pN2 subjects.Apparent disagreements and inconsistency exist in study reports concerning the prognostic significance of certain factors in pN2 NSCLC,especially regarding to the issue about whether skip N2 metastasis benefit from surgery.Methods We therefore performed this comprehensive summary of the published literatures to draw a more precise and less uncertain conclusion.After a comprehensive literature search,a total of 73 studies involving 23,773 subjects were included according to eligibility criteria.Results As expected,most of the investigated factors,such as old age,male,advanced pathological T stage,advanced clinical N stage,multiple N2 stations,extended surgical resection(pneumonectomy),and incomplete resection,but not post-operation treatment(eg.chemotherapy and radiotherapy)were significantly associated with poor survival.However,skip N2 metastasis was favourable prognostic factors in operable pN2 NSCLC subjects.Other factors(histological type and primary tumour side)were neutral in terms of association with overall survival.We highlighted a number of important prognostic factors for pN2 NSCLC patients.Particularly,patients with skip N2 disease benefit from surgery.Conclusion Our findings could be used as reference information for decision-making in clinical practice and future study design.

Impact and Analysis of Prognostic Factors in Patients with Non-Metastatic Esophageal Squamous Cell Carcinoma: A Retrospective Single Institution Study

Objective: To investigate the impact of local tumor factors on the prognosis of non-metastatic esophageal squamous cell carcinoma patients. Methods: We performed a retrospective analysis of data from 278 consecutive esophageal squamous cell carcinoma patients between January 2009 and December 2016. The prognosis factors such as the GTV volume, GTV maximum diameter, and GTV length were analyzed. Results: The results of ROC curve analysis showed that prognosis critical values of the GTV volume, GTV maximum diameter, and GTV length were 27.98 cm3, 1.80 and 5.85 cm, respectively. The result of the univariate analysis showed that the GTV volume (P = 0.0184), GTV maximum diameter (P = 0.0246), and GTV length (P = 0.0035) were the prognostic factors for overall survival;the barium meal length (P = 0.0149) was the prognostic factor for local control. The multivariate analysis showed that the barium meal length (P = 0.0013), GTV maximum diameter (P = 0.0047), and GTV length (P = 0.0032) as the independent prognostic factors associated with overall survival;the barium meal length (P = 0.0037) was the only independent prognostic factors for local control. Conclusion: The esophageal lesion length was the main prognosis factor for patients with non-metastatic esophageal squamous cell carcinoma. Therefore, we suggest that the physician must give enough attention to these patients in clinical practice, and give active treatment.
