Risk Factors for Geo-Helminthiasis in Children Aged 6 - 36 Months in a Rural Health District in Cameroon

Introduction and Objectives: Soil-Transmitted-Helminthiasis (STH) is a public health problem in Cameroon. The control strategies currently in place, particularly chemoprevention, has shortcomings linked to the target population, which are school-age children. The objective was to determine the prevalence and the risk factors associated with geo-helminthiasis in children aged 0 to 3 years in a rural health district. Method: From December 2020 to May 2021, a descriptive and analytical cross-sectional study of 376 children between 6 and 36 months was carried out in the Akonolinga health district. This was a cluster sampling in 4 health areas. Stool samples were collected and analysed using the mini-FLOTAC method. The results expressed as the number of eggs per gram of stool. A questionnaire on socio-demographic and lifestyle data was administered to the parents. The Chi-squared test was used to measure the association between geo-helminth infection and the data collected. A multivariate analysis using logistic regression was performed (p 0.05). Results: The prevalence of STH was 19.4% (Ascaris lumbricoides: 16% and Trichuris trichiura: 8%). Risk factors were: consumption of contaminated water (AOR = 1.93 [1.03 - 3.6];p = 0.040), early contact of the child with the ground (before age of 4 months) (AOR = 4.9 [2.1 - 11.37];p .001), habit of walking barefoot (AOR = 2.91 [1.1 - 7.97];p = 0.038), and living in a habitat with unpaved ground (AOR = 7.4 [1.55 - 35.7];p = 0.012). Conclusion: The prevalence of STHs in infants was high. Preventive chemotherapy should be extended to this age-group, and other measures intensified.

Phenolic Profile,Antioxidant,Antihyperlipidemic and Cardiac Risk Preventive Effect of Pigmented Black Rice Variety Chakhao poireiton in High-Fat High-Sugar Induced Rats

The present study aimed to investigate the hypolipidemic,antioxidant and cardiac risk-suppressing effects of Chakhao poireiton(CP),a GI-tagged pigmented black rice from India.In vitro and ex vivo studies confirmed that whole rice extracts of CP have potent antioxidant,3-hydroxy-3-methylglutaryl-CoA reductase,cholesterol esterase inhibitory,and antilipase effects.An in vivo study was conducted to evaluate the effects of the ethanol extracts of CP on high-fat high-sugar induced hyperlipidemic rats.The ethanol extract significantly ameliorated lipid parameters and liver enzymes to normal.Levels of lactate dehydrogenase,creatine kinase-N-acetyl cysteine,C-reactive protein,and lipoprotein a were significantly lower in the extract-treated groups than those in the disease control group.A marked reduction of ApoB/ApoA1 and other atherogenic indices were observed in extract-treated groups.Twelve phenolic compounds,i.e.rosamarinic acid,gallic acid,protocatechuic acid etc.,were quantified in CP.This study provided the first evidence of the antihyperlipidemic and cardiac risk inhibitory effects of CP,which would be beneficial in preventing and managing hyperlipidemia,associated oxidative stress,and cardiac complications.

Distribution of High-Risk Human Papillomavirus Genotypes among Women with Colposcopic Diagnosis of Cervical Intraepithelial Neoplasia in Bangladesh

Background: The incidence of cervical cancer is high in Bangladesh and there is a high prevalence of preinvasive lower genital tract disease among women of reproductive age. Persistent high-risk Human Papilloma Virus (HPV) infection is the main underlying cause of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN). Objective: The aim of the study was to identify the subtypes of high-risk HPV infection among women with the colposcopic diagnosis of cervical intraepithelial neoplasia in Bangladesh. Methods: This cross-sectional observational study was conducted in the colposcopy clinic of Dhaka Medical College Hospital over a six-month period. A total of 100 participants were enrolled. Married women, between 30 - 60 years of age with colposcopically diagnosed cervical intra epithelial neoplasia were enrolled. Women with chronic illness, pregnancy, and women unable to consent were excluded from this study. After counselling, colposcopically directed punch biopsies were taken from each CIN case concurrently with high-risk HPV testing by polymerase chain reaction (PCR). Results: The mean age of the patients was 38.69 (SD ±7.76) years. CIN 1 was diagnosed in 57% of participants, while 24% had CIN II and 19% had CIN III lesions. High-risk HPV was present in 52 patients. HPV 16 was the most common identified in 28 (53.84%) and HPV 18 was the second most common with 20 (38.46%) either singly or in combination with other high-risk subtypes. The other HPV strains, HPV 31, 33, 35, 52, 56 and 58, were also detected either as mono or co-infections. Out of the 52 HPV positive cases, 29 (55.8%) had mono infection and 23 (44.2%) had co-infection with several subtypes. The highest incidence (50%) of oncogenic HPV infections was present among women aged 35 - 45 years. Risk factors associated with HPV positive cases were high parity (P 0.05), early age at marriage (P = 0.754) and early age of first child. Conclusion: This study identified a high prevalence of HPV 16 and 18 genotypes. HPV vaccination with the current 9-valent HPV vaccine, which contains HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. Will be an effective public health measure to eradicate cervical cancer in Bangladesh.

A survey of high risk factors affecting retinopathy in full-term infants in China

AIM: To investigate the possible relationship between the influencing factors occurring before and during birth in full-term infants and the outcome of retinopathy. METHODS: Totally 816 full-term infants admitted in the neonate intensive unit of Boai Hospital of Zhongshan between 1 May, 2008 and 30 June, 2011 were included in the study. Fundus examination was performed and evaluated individually on them at the age of 48 hours after delivery, 2 weeks and 1 month. Some possible risk factors happening prenatally or during delivery such as pregnant related hypertension, placenta previa, placental abruption etc, as well as some neonatal risk factors such as neonatal asphyxia, hypoxic-ischemic encephalopathy (HIE), low birth weight etc, were recorded and evacuated. Then the effect of the risk factors of full-term infants on retinopathy was studied. RESULTS: The incidence of retinal hemorrhage of full-term infants with prenatal pregnant related hypertension (PRH) of the mother (43.6%) was significantly higher than that of full-term infants without (8.0%). (P<0.001). The incidence of retinal hemorrhage of full-term infants with neonatal asphyxia and /or hypoxic-ischemic encephalopathy (HIE)(29.3%) was significantly higher than that of those without (15.7%), but correlation was not found between the severity of retina hemorrhage and the degree of hypoxic disease. A pale color of optic disc was associated with a low birth weight of full-term infant. Full-term infants with birth weigh-less than 2500g had a significant higher incidence of retinopathy than those with birth weight equal or more than 2500g( P<0.001). CONCLUSION: The main influencing factors which lead to retinopathy of high risk full-term infants are prenatal factors such as PRH, and some neonatal risk factors such as asphyxia, hypoxic-ischemic encephalopathy, and low birth weight.

Clinical Significance of Serum Uric Acid Combined with Cystatin C Detection in Patients with Different Levels of Hypertension with High Risk Degree and Above

Objective: To explore the clinical significance of serum uric acid combined with cystatin C detection in high risk degree of hypertension of different grades. Methods: The patients who were treated in the Department of Cardiovascular Medicine of our hospital from January to December 2022 were selected as the study subjects, and the high risk and extremely high risk groups of grade I, II and III hypertension were selected for comparative analysis to explore their clinical significance. Results: There was a statistically significant difference in the number of patients with extremely high risk of grade II hypertension between men and women (P 0.05), which showed that there was no specificity in the concentration detection of serum uric acid and cystatin C in different grades of hypertension;there was no significant difference in serum uric acid concentration between grade II and grade III of hypertension with high risk grade and cystatin C concentration between grade I and grade III of hypertension with high risk grade (P > 0.05), but there was significant difference in the concentration detection of serum uric acid and cystatin C between the other groups (P < 0.05), which indicates that the detection of serum uric acid and cystatin C has important clinical significance in the high risk degree of hypertension. Conclusion: In the comparison of the detection of blood uric acid and cystatin C in different levels of hypertension with extremely high risk, the difference of cystatin C in grade I and grade III was not statistically significant, and the rest were statistically significant;therefore, the detection of serum uric acid and cystatin C can provide reliable laboratory data for clinical diagnosis and treatment of the extremely high risk degree of different levels of hypertension.

Hemodynamic monitoring and management of patients undergoing high-risk surgery:a survey among Chinese anesthesiologists

Hemodynamic monitoring and optimization improve postoperative outcome during high-risk surgery.However,hemodynamic management practices among Chinese anesthesiologists are largely unknown.This study sought to evaluate the current intraoperative hemodynamic management practices for high-risk surgery patients in China.From September 2010 to November 2011,we surveyed anesthesiologists working in the operating rooms of 265 hospitals representing 28 Chinese provinces.All questionnaires were distributed to department chairs of anesthesiology or practicing anesthesiologists.Once completed,the 29-item questionnaires were collected and analyzed.Two hundred and 10 questionnaires from 265 hospitals in China were collected.We found that 91.4%of anesthesiologists monitored invasive arterial pressure,82.9%monitored central venous pressure（CVP）,13.3%monitored cardiac output（CO）,10.5%monitored mixed venous saturation,and less than 2%monitored pulse pressure variation（PPV） or systolic pressure variation（SPV） during high-risk surgery.The majority（88%） of anesthesiologists relied on clinical experience as an indicator for volume expansion and more than 80%relied on blood pressure,CVP and urine output.Anesthesiologists in China do not own enough attention on hemodynamic parameters such as PPV,SPV and CO during fluid management in high-risk surgical patients.The lack of CO monitoring may be attributed largely to the limited access to technologies,the cost of the devices and the lack of education on how to use them.There is a need for improving access to these technologies as well as an opportunity to create guidelines and education for hemodynamic optimization in China.

High-dose Chemotherapy Combined with Autologous Hematopoietic Stem Cell Transplantation as Frontline Therapy for Intermediate/High-risk Diffuse Large B Cell Lymphoma

The role of autologous hematopoietic stem cell transplantation(auto-HSCT)following high-dose chemotherapy has been validated and accepted as a standard treatment for patients with relapsed diffuse large B-cell lymphoma(DLBCL).However,its clinical efficacy as frontline therapy remains to be elucidated.This study aimed to examine the feasibility of frontline auto-HSCT for newly diagnosed intermediate/high-risk DLBCL patients.We retrospectively reviewed the data of 223 patients treated with frontline auto-HSCT or chemotherapy alone(year 2008-2014)from four hospitals.The median follow-up time was 29.4 months.Between the two treatment arms among the intermediate/high-risk DLBCL patients,the 3-year overall survival(OS)and progression-free survival(PFS)rates of patients given frontline auto-HSCT were 87.6%and 81.9%,respectively,and the chemotherapy-alone group showed 3-year OS and PFS rates of 64.9%and 59.59%,respectively.Compared with the chemotherapy-alone group,the frontline auto-HSCT could eliminate the adverse impact of non-germinal center B-cell(GCB)type.In addition,in the frontline auto-HSCT group,patients who achieved complete response(CR)at auto-HSCT had a longer survival time than those who did not achieve CR.Our results suggested that frontline auto-HSCT could improve the prognosis of intennediate/high-risk DLBCL patients.

Greenlight Photoselective Vaporisation of the Prostate in 133 High Surgical Risk Patients: A 5-Year Outcome Study

Greenlight photoselective vaporisation of the prostate (GPVP) is progressively becoming an established treatment in patients with LUTS because it is a minimally invasive technique that achieves efficient haemostasis, making it the ideal technique for patients at high surgical risk. Material and Methods: To study of 133 patients with an ASA surgical risk score of 3 or 4, undergoing GPVP, with an analysis of perioperative outcome, IPSS, Qmax, IIEF-5 and complications during a five-year follow-up. Results: At 5 years the mean annual improvement in IPSS was stable, and at 5 years there was a 15.2 point improvement versus the preoperative score (p 0.05). The Qmax showed an improvement of 14.9 ml/sec and was maintained at five years after surgery (p 0.05). No patients were transfused or suffered urinary incontinence. 2.25% suffered major complications and there were no deaths. 3.1% of patients suffered de novo urgency. In the 5-year follow-up, five patients had to be reoperated. The quality of sexual health assessed by IIEF-5 before the procedure was scored at 14 points;the 5-year follow-up covering the preoperative period and all revisions did not show any worsening in the IIEF-5 score (p > 0.05). Conclusions: Due to its physical characteristics, in our opinion GPVP is now the treatment of choice in patients at high surgical risk. In our series, the risk of major/minor complications and transfusions was much lower than the same risks in conventional techniques. The objective results (Qmax and quality of life questionnaire) are equivalent to conventional techniques and persist over a 5-year follow-up.

High risk populations and HIV-1 infection in China

China is currently experiencing one of the most rapidly expanding HIV epidemics in the world. Although the overall prevalence rate is still low, with a population of 1.3 billion, high-risk factors which have contributed to the HIV/AIDS epidemics worldwide continue to prevail in China, including a high rate of injecting drug use and needle sharing, commercial sex with low rates of condom use, and concurrent sex with both commercial sex workers and noncom- mercial casual or steady sex partners. In addition, there are increasing “double risk” populations overlapping drug users and sex workers, as well as increasing rates of STDs and HIV among high-risk populations. Sexual transmission, therefore, may serve as a bridge connecting high-risk populations with general populations. There is an urgent need to prevent the spread of HIV from these high-risk populations into the general population of China.

Study on the temperature characteristic and high temperature risk of asphalt layer of Beijing-Xinjiang ExpresswayWutong Daquan to Yiwu Section

High temperature rutting is a typical highway damage in Xinjiang, China, and its trigger process usually has a close relationship with characteristics of road temperature distribution. A numerical model of earth-atmosphere coupling heat transfer on a typical section of the Beijing-Xinjiang Expressway(G7) from Wutong Daquan to Yiwu was established in this work. Spatiotemporal characteristics of pavement structure layer temperature distribution, frequency and duration times of road surface high temperature from May 1 to September 30 are statistically studied. The effects of wind speed, weather and air temperature on asphalt layer and pavement temperature are analyzed. The results show that:(1) Spatial and temporal temperature distribution characteristics of pavement structural layers are greatly affected by the coupled earth-atmosphere heat transfer process. Surface temperature increases along the airflow direction and daily temperature variation of the pavement structure layer decreases with an increase of depth.(2) G7 expressway will face the challenge of high rutting damage. The proportion of temperature higher than 50 ℃ for pavement surface and asphalt upper layer both exceeds 50%and high temperature of road lasts for more than six hours in numerous days.(3) High temperatures of asphalt pavement are usually associated with low ambient wind speeds, while the wind flow has little cooling effect when the road surface temperature is relative high. Weather conditions have a significant impact on temperature of the road surface. The probability of high temperature in sunny days is obviously higher than other weather conditions.(4) Pavement temperature rises as air temperature rises. When air temperature is higher than 30 °C, the proportion of pavement daily maximum temperature over softening point reaches up to 78%.

Prevalence of High Non-high-density Lipoprotein Cholesterol and Associated Risk Factors in Patients with Diabetes Mellitus in Jilin Province,China:A Cross-sectional Study

Dyslipidemia is a risk factor for cardiovascular diseases（CVDs）in patients with diabetes,and non-high-density lipoprotein cholesterol（non-HDL-C）is a better predictor of CVDs than low-density lipoprotein cholesterol（LDL-C）in patients with diabetes.Therefore,we aimed to investigate the distribution of non-HDL-C and the prevalence of high non-HDL-C level in Chinese patients with diabetes mellitus and identify the

Observation of the effect of one-to-one education on high-risk cases of diabetic foot

BACKGROUND Diabetes is a common chronic disease,and its global incidence is on the rise.The disease is directly attributed to insufficient insulin efficacy/secretion,and patients are often accompanied by multiple complications.Diabetic foot is one of the most common complications of diabetes.Diabetic feet have ulcers and infections,which can eventually lead to amputation.Basic nursing care,such as lowering blood pressure and preventing foot skin infections in clinical nursing work,has positive significance for the prevention and control of diabetic feet.AIM To explore the positive significance of one-to-one education in high-risk cases of diabetic foot.METHODS This observation included 98 high-risk cases of diabetic foot in our hospital during the period from August 2017 to October 2019,and these patients were randomly divided into the basic nursing group and the one-to-one education group with 49 patients per group.The basic nursing group only received routine basic nursing,while the one-to-one education group gave patients one-to-one education on the basis of basic nursing.After nursing,the self-care ability and compliance behavior of the two groups were evaluated and compared between these two groups.The knowledge mastery of the patient and the satisfaction of nursing were accounted.RESULTS The assessment results of patients(self-care responsibility,self-care skills,selfconcept and self-care knowledge)were significantly higher in the one-to-one education group than in the basic nursing group.The scores of compliance behaviors(foot bathing,shoes and socks selection,sports health care)in the oneto-one education group were significantly higher than those in the basic nursing group.Patients in the one-to-one education group had a significantly higher level of knowledge mastery and satisfaction of nursing than the basic nursing group.CONCLUSION One-to-one education for high-risk cases of diabetic foot is helpful to improve the cognition and self-care ability of patients with diabetic foot,to ensure that patients follow the doctor’s advice of self-care and to improve their nursing satisfaction.

Cost-benefit analysis of esophageal cancer endoscopic screening in high-risk areas of China

AIM:To estimate the cost-benefit of endoscopic screening strategies of esophageal cancer(EC)in high-risk areas of China. METHODS:Markov model-based analyses were conducted to compare the net present values(NPVs)and the benefit-cost ratios(BCRs)of 12 EC endoscopic screening strategies.Strategies varied according to the targeted screening age,screening frequencies,and follow-up intervals.Model parameters were collected from population-based studies in China,published literatures,and surveillance data. RESULTS:Compared with non-screening outcomes,all strategies with hypothetical 100 000 subjects saved life years.Among five dominant strategies determined by the incremental cost-effectiveness analysis,screening once at age 50 years incurred the lowest NPV(international dollar-I$55 million)and BCR(2.52).Screening six times between 40-70 years at a 5-year interval[i.e., six times(40)f-strategy]yielded the highest NPV(I$99 million)and BCR(3.06).Compared with six times(40)fstrategy,screening thrice between 40-70 years at a 10-year interval resulted in relatively lower NPV,but the same BCR. CONCLUSION:EC endoscopic screening is cost-beneficial in high-risk areas of China.Policy-makers should consider the cost-benefit,population acceptance,and local economic status when choosing suitable screening strategies.

Ultrasound guided percutaneous cholecystostomy in high-risk patients for surgical intervention

AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 × 103 ± 1.3 × 103 μg/L vs 13 × 103 ± 1 × 103 μg/L, P < 0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs 8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ± 10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/L vs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35℃ vs 37.3 ± 0.32℃, P < 0.05 for 24 h after PC; 38 ± 0.35℃ vs 36.9 ± 0.15℃, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recoveredwith medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. CONCLUSION: As an alternative to surgery, percutan- eous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

Dual-doping for enhancing chemical stability of functional anionic units in sulfide for high-performance all-solid-state lithium batteries

The sulfide-based solid-state electrolytes(SEs)reactivity toward moisture and Li-metal are huge barriers that impede their large-scale manufactu ring and applications in all-solid-state lithium batteries(ASSLBs).Herein,we proposed an Al and O dual-doped strategy for Li_(3)PS_(4)SE to regulate the chemical/electrochemical stability of anionic PS_(4)^(3-)tetrahedra to mitigate structural hydrolysis and parasitic reactions at the SE/Li interface.The optimized Li_(3.08)A_(10.04)P_(0.96)S_(3.92)O_(0.08)SE presents the highestσLi+of 3.27 mS cm^(-1),which is~6.8 times higher than the pristine Li_(3)PS_(4)and excellently inhibits the structural hydrolysis for~25 min@25%humidity at RT.DFT calculations confirmed that the enhanced chemical stability was revealed to the intrinsically stable entities,e.g.,POS33-units.Moreover,Li_(3.08)Al_(0.04)P_(0.96)S_(3.92)O_(0.08)SE cycled stably in Li//Li symmetric cell over 1000 h@0.1 mA cm^(-2)/0.1 mA h cm^(-2),could be revealed to Li-Al alloy and Li_(2)Oat SE/Li interface impeding the growth of Li-dendrites during cycling.Resultantly,LNO@LCO/Li_(3.08)Al_(0.04)P_(0.96)S_(3.92)O_(0.08)/Li-In cell delivered initial discharge capacities of 129.8 mA h g^(-1)and 83.74%capacity retention over 300 cycles@0.2 C at RT.Moreover,the Li_(3.08)Al_(0.04)P_(0.96)S_(3.92)O_(0.08)SE presented>90%capacity retention over 200 and 300 cycles when the cell was tested with LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)(NCA)cathode material vs.5 and 10 mg cm^(-2)@RT.

Predictors of rebleeding after initial hemostasis with epinephrine injection in high-risk ulcers

AIM: To identify the predictors of rebleeding after initial hemostasis with epinephrine injection (EI) in patients with high-risk ulcers. METHODS: Recent studies have revealed that endoscopic thermocoagulation, or clips alone or combined with EI are superior to EI alone to arrest ulcer bleeding. However, the reality is that EI monotherapy is still common in clinical practice. From October 2006 to April 2008, high-risk ulcer patients in whom hemorrhage was stopped after EI monotherapy were studied using clinical, laboratory and endoscopic variables. The patients were divided into 2 groups: sustained hemostasis and rebleeding. RESULTS: A total of 175 patients (144, sustainedhemostasis; 31, rebleeding) were enrolled. Univariate analysis revealed that older age (≥ 60 years), advanced American Society of Anesthesiology (ASA) status (category Ⅲ , Ⅳ and Ⅴ ), shock, severe anemia (hemoglobin < 80 g/L), EI dose ≥ 12 mL and severe bleeding signs (SBS) including hematemesis or hematochezia were the factors which predicted rebleeding. However, only older age, severe anemia, high EI dose and SBS were independent predictors. Among 31 rebleeding patients, 10 (32.2%) underwent surgical hemostasis, 15 (48.4%) suffered from delayed hemostasis causing major complications and 13 (41.9%) died of these complications. CONCLUSION: Endoscopic EI monotherapy in patients with high-risk ulcers should be avoided. Initial hemostasis with thermocoagulation, clips or additional hemostasis after EI is mandatory for such patients to ensure better hemostatic status and to prevent subsequent rebleeding, surgery, morbidity and mortality.
