Prevalence, Risk Factors, and Awareness of Chronic Kidney Disease among Diabetes Mellitus and Hypertensive Individuals at the Buea Regional Hospital, Cameroon

Background: Kidney failure, cardiovascular disease, and early mortality are just a few of the major negative effects of chronic renal disease, a serious global health issue. The considerable financial and public health burden associated with chronic kidney disease can be lessened by raising awareness and adopting better practices for its impact, prevention, and early identification. Objective: In this study, individuals with hypertension and diabetes were evaluated for their knowledge of chronic kidney disease, its prevalence, and its risk factors. Method: It was a hospital-based cross-sectional study conducted on adult (>18 years) patients with diabetes mellitus and hypertension. Each participant provided written informed consent before having their data collected through interviews, medical information, and blood samples for CKD screening. The CKD epidemiology collaboration (CKD-EPI) equation was used to calculate the glomerular filtration rate (GFR) from serum creatinine, and CKD was determined using the estimated GFR (e-GFR). To find independent CKD factors, multivariate logistic regression was employed, with a p-value of 0.05 being regarded as statistically significant. This was accomplished using SPSS (Statistical Program for Social Sciences) version 22.0, IBM Corp., Armonk, NY. Result: A total of 156 participants took part in the study among which 95 (60.9%) were male, most of the participants 82 (52.6%) were aged between 51 - 70 years (mean 59.42 ± 11.007), 76 (48.7%) were unemployed and 97 (62.2%) were single. Overall, the knowledge score of participants on CKD was 65.4% for good knowledge and 34.6% for poor or inadequate knowledge of CKD. More than half of the participants (60%) had chronic kidney disease. Among these, the greatest proportion of CKD patients were those who were hypertensive (88.2%) followed by those who were both hypertensive and diabetic (70.7%). Conclusion: There is poor management of CKD in the South West Region of Cameroon which has contributed greatly to the progression of CKD and increases in the mortality rate.

Independent risk factors for depression in older adult patients receiving peritoneal dialysis for chronic kidney disease

BACKGROUND According to the trend of global population aging,the proportion of elderly patients with chronic kidney disease(CKD)is expected to increase.However,there are more than 20 million people in China with decompensated kidney function,of which 19.25%are elderly people.Therefore,special attention should be paid to the education years,sleep quality,anxiety status,comorbidities with diabetes,cardiovascular disease(CVD),and anemia as independent risk factors for depression in elderly CKD patients.This study explores the clinical management of elderly CKD patients that should address these risk factors to prevent depression and improve their prognosis.AIM To investigate depression risk factors in older patients receiving peritoneal dialysis,aiding future prevention of depression in these patients.METHODS This retrospective study included a primary study population of 170 patients with CKD who received peritoneal dialysis from January 2020 to December 2022.We assessed the patients’mental status using the Beck Depression Inventory Score-II(BDI-II),Self-Rating Anxiety Scale(SAS),Anxiety Inventory Score,and the Pittsburgh Sleep Quality Index(PSQI).Logistic regression was employed to identify depression independent risk factors among these patients.RESULTS The non-depressed group had a significantly longer education period than the depressed group(P<0.05).The depressed group exhibited significantly higher mental status scores than the non-depressed group(P<0.001).Patients with diabetes mellitus(DM)or CVD had a higher probability of developing depression.Patients with depression had significantly lower hemoglobin and albumin levels than patients without depression(P<0.05).Spearman correlation analysis of BDI-II scale scores,measuring depression,indicated positive correlations with BDI-II and SAS scores as risk factors for depression in patients with CKD.In contrast,years of education,hemoglobin levels,and peritoneal Kt/V were negatively correlated,serving as protective factors against depression.An analysis of variance for influences with significant differences in the univariate analysis revealed that years of schooling,BDI-II,SAS,PSQI,DM,CVD,and hemoglobin levels independently influenced depression in older patients with CKD.CONCLUSION Education,BDI-II,SAS,PSQI,DM,and CVD are independent risk factors for depression in older patients with CKD;therefore,post-treatment psychological monitoring of high-risk patients is crucial to prevent depression.

Risk Factors of Reoperation and Outcome of Patients Operated for Chronic Subdural Hematoma in a Teaching Hospital in Rabat

Background: chronic subdural hematoma is a common pathology, especially in the elderly. Although it has a good prognosis, it poses the problem of recurrence after surgical evacuation. Objective: To analyze the risk factors of reoperation in patients surgically treated for chronic subdural hematoma (cSDH) and evaluate the outcome of patients who benefited from a reoperation. Materials and Methods: A retrospective review was conducted in a single University Hospital Center in Rabat (Morocco) on 49 patients operated on from January 2020 to June 2021 for cSDH. Possible risk factors described in the literature were analyzed and the outcome of post-operative course was evaluated. Statistical significance was defined by p-value Results: 49 patients underwent surgical evacuation of cSDH. The sex ratio of male/female was 3.08. The mean age was 70.6 years. Concerning the medical history, 8.2% were diabetics, 10.2% had heart disease, 18.4% had hypertension, 16.3% associated of comorbidities, 2% had pulmonary embolism, and 2% had neoplasm. 18.4% were on anticoagulation therapy, no patients were on new oral anticoagulants. The clinical findings upon admission were motor deficit at 57.1%, signs of intracranial hypertension at 20.4%, altered consciousness at 16.9% and impaired behavior at 6.1%. 28.6% of patients had a past history of head trauma. The pre-operative CT scan showed unilateral cSDH at 81.6%, midline shifts at 77.6%, and false membranes at 34.7%. Blood appeared chronic at 40.8%, subacute at 24.5%, and mixed densities at 34.7%. The post-operative course was uneventful in 73.5%. According to Ibanez grading 8 patients had mild complications (grade I) and 5 moderate complications (grade II) after the first surgery. We recorded 10.2% of patients who needed a second surgery because of the deterioration of neurologic status or motor deficit associated with an abnormal CT scan. According to the GOS, 85.7% of patients had a good recovery while 10.2% died. None of the factors assessed was found to be a risk factor for reoperation. Conclusion: No risk factors of reoperation after an initial burr hole evacuation for cSDH were found. However medical history and male sex was common condition among reoperated patients with their CT scan showing a chronic aspect of blood, midline shift and false membranes. Most patients who underwent revision surgery died on the postoperative course.

Risk factors and their interactive effects on severe acute pancreatitis complicated with acute gastrointestinal injury

BACKGROUND There are many risk factors for severe acute pancreatitis(SAP)complicated with acute gastrointestinal injury(AGI),but few reports on the interaction between these risk factors.AIM To analyze the risk factors for SAP complicated with AGI and their interactive effects.METHODS We selected 168 SAP patients admitted to our hospital between December 2019 and June 2022.They were divided into AGI group and non-AGI group according to whether AGI was present.Demographic data and laboratory test data were compared between the two groups.The risk factors for SAP with concomitant AGI were analyzed using multifactorial logistic regression,and an analysis of the interaction of the risk factors was performed.RESULTS The percentage of patients with multiple organ dysfunction syndrome,acute physiological and chronic health scoring system II(APACHE II)score,white blood cell count and creatinine(CRE)level was higher in the AGI group than in the non-AGI group.There was a statistically significant difference between the two groups(P<0.05).Logistic regression analysis indicated that an APACHE II score>15 and CRE>100μmol/L were risk factors for SAP complicating AGI.The interaction index of APACHE II score and CRE level was 3.123.CONCLUSION An APACHE II score>15 and CRE level>100μmol/L are independent risk factors for SAP complicated with AGI,and there is a positive interaction between them.

Risk factors for progression to acute-on-chronic liver failure during severe acute exacerbation of chronic hepatitis B virus infection

BACKGROUND Acute exacerbation in patients with chronic hepatitis B virus(HBV) infection results in different severities of liver injury. The risk factors related to progression to hepatic decompensation(HD) and acute-on-chronic liver failure(ACLF) in patients with severe acute exacerbation(SAE) of chronic HBV infection remain unknown.AIM To identify risk factors related to progression to HD and ACLF in compensated patients with SAE of chronic HBV infection.METHODS The baseline characteristics of 164 patients with SAE of chronic HBV infection were retrospectively reviewed. Independent risk factors associated with progression to HD and ACLF were identified. The predictive values of our previously established prediction model in patients with acute exacerbation(AE model) and the model for end-stage liver disease(MELD) score in predicting the development of ACLF were evaluated.RESULTS Among 164 patients with SAE, 83(50.6%) had compensated liver cirrhosis(LC),43 had progression to HD without ACLF, and 29 had progression to ACLF within 28 d after admission. Independent risk factors associated with progression to HD were LC and low alanine aminotransferase. Independent risk factors for progression to ACLF were LC, high MELD score, high aspartate aminotransferase(AST) levels, and low prothrombin activity(PTA). The area under the receiver operating characteristic of the AE model [0.844, 95%confidence interval(CI): 0.779-0.896] was significantly higher than that of MELD score(0.690, 95%CI: 0.613-0.760, P < 0.05) in predicting the development of ACLF.CONCLUSION In patients with SAE of chronic HBV infection, LC is an independent risk factor for progression to both HD and ACLF. High MELD score, high AST, and low PTA are associated with progression to ACLF. The AE model is a better predictor of ACLF development in patients with SAE than MELD score.

Risk factors for liver-related mortality in chronic hepatitis C patients:A deceased case-living control study

AIM:To investigate the risk factors for liver-related mortality in chronic hepatitis C(CHC)patients.METHODS:All deceased CHC inpatient data were collected from the Beijing 302 Hospital clinical database,which includes more than 8250 CHC inpatients during the period from 2002 to 2012.The controls were matched to cases by age(±2 years),sex and date of hospital admission(within the same year).Potential risk factors were included for the evaluation,and odds ratios(OR)and 95%CI were estimated using univariate(unadjusted)and multivariate(adjusted OR,AOR)conditional logistic regression.All statistical tests were two-sided.P values<0.05 were considered statistically significant.RESULTS:Based on examinations of 144 CHC-related deceased cases and 576 controls,we found that antiviral therapy with interferon-αwas associated with a 47%decrease in the risk of hepatic mortality(AOR=0.53,95%CI:0.28-0.99,P=0.048).Additionally,the initial diagnostic stage of the disease(AOR=2.89,95%CI:1.83-4.56 and P<0.001 for liver cirrhosis/AOR=8.82,95%CI:3.99-19.53 and P<0.001for HCC compared with CHC),diabetes(AOR=2.35,95%CI:1.40-3.95,P=0.001),hypertension(AOR=1.76,95%CI:1.09-2.82,P=0.020),alcohol consumption(AOR=1.73,95%CI:1.03-2.81,P=0.037)and HBsAg positivity(AOR=22.28,95%CI:5.58-89.07,P<0.001)were associated with a significant increase in the risk of liver-related mortality in CHC patients.CONCLUSION:This study indicates that interferon-αtreatment,the stage at the initial diagnosis of the disease and comorbidities are all independent risk factors for liver-related mortality in CHC patients.

Risk factors for depression in patients with chronic obstructive pulmonary disease

BACKGROUND The prevalence of depression in patients with chronic obstructive pulmonary disease(COPD)ranges from 10%to 42%,but the diagnosis of depression in patients with COPD is often unrecognized and untreated.Unrecognized depression has major implications for compliance with medical treatment,prolonged lengths of stay,increased frequency of hospital admissions,and increased consultations with primary care physicians.Many studies have attempted to identify risk factors for progression,prognosis and response to therapy in patients with depression.However,few studies have examined the risk factors for depression in patients with COPD,and some results remain controversial.AIM To identify the potential risk factors to define patients with COPD who are at“high risk”of depression.METHODS The clinical data of 293 patients with COPD were reviewed from January 2017 to December 2018.The correlations between demographics,clinical characteristics and depression were analyzed.The risk factors for depression in patients with COPD were identified by multivariate logistic regression analysis.The cutoff value,sensitivity and specificity of the independent correlation factors were calculated with a receiver operating characteristic curve.RESULTS Of the 293 patients included,65(22.18%)individuals were identified to have depression.Significant differences were detected between patients with and without depression in terms of body mass index(BMI),forced expiratory volume in 1 s(FEV1),and COPD assessment test(CAT)score(all P<0.05).Low BMI,low FEV1,and high CAT were independent risk factors for depression in patients with COPD and the cutoff values of BMI,FEV1,and CAT scores were 21.373 kg/m2,0.855 L and 12.5,respectively.CONCLUSION Low BMI,low FEV1,and high CAT score were identified as independent risk factors for depression in patients with COPD.

Risk factors related to chronic rhegmatogenous retinal detachment

AIM: To evaluate the clinical factors related to chronic rhegmatogenous retinal detachment (RRD). METHODS: A retrospective case-control study. A total of 103 consecutive patients (103 eyes) with primary RRD were studied to evaluate the clinical factors related to chronic RRD. RESULTS: Chi-square test was used to sift out the following associated factors with chronic RRD: younger patients(P=0.0028), better preoperative best corrected visual acuity (BCVA, P=0.0316), atrophic retinal break (P<0.0001), inferior retinal break (P<0.0001), smaller break (P=0.0005); then the independent risk factors related to chronic RRD was determined by stepwise logistic regression analysis as following: atrophic retinal break (odds ratio (OR)=7.997, P=0.007), inferior retinal break (OR=14.127, P<0.0001) and better preoperative BCVA (OR=1.636 P<0.0722). CONCLUSION: Atrophic retinal break, inferior retinal break and better preoperative BCVA are the independent risk factors related to chronic RRD.

The risk factors for chronic obstructive pulmonary disease in Li and Han ethnic groups in Hainan, China

Objective: To investigate the risk factors of chronic obstructive pulmonary disease(COPD) in Li and Han ethnic group in Hainan, China. Methods: All subjects were randomly selected from various regions in Hainan. General characteristics were compared between COPD cases and healthy control cases in both Li and Han ethnic groups. The odds ratio(OR), the corresponding 95% confidence interval(CI) of COPD were calculated by logistic regression.Results: A total of 277 Li COPD cases, 307 Li healthy control subjects, 290 Han COPD cases and 301 Han healthy control were included in this study. In both the Li and Han groups, the average age exceeded 65 years, and the cigarette number smoked per day and the smoking duration were correlated with risk of COPD. In the Li COPD subjects, low weight, smoking, and recurrent infection of respiratory tract were mainly risk factors; while the mainly risk factor of Han COPD subjects was family history of respiratory disease. Conclusions: The risk factors are different in COPD subjects of Han and Li nationalities in Hainan of China. The age and smoking are strongly correlated with COPD risk.

Risk factors and urinary biomarkers of non-albuminuric and albuminuric chronic kidney disease in patients with type 2 diabetes

BACKGROUND A number of recent studies indicate a transformation in the natural course of chronic kidney disease(CKD)in type 2 diabetes(T2D)patients:an increasing prevalence of declined renal function without proceeding to the accompanying elevation of albuminuria.It has been suggested that albuminuric and nonalbuminuric CKD patterns could be different in their phenotypes and pathogenic mechanisms.AIM To identify the risk factors and biomarkers of albuminuric and non-albuminuric patterns of CKD in patients with T2D.METHODS Three hundred sixty patients with T2D duration≥10 years were included in this observational cross-sectional study.The associations of a panel of demographic and clinical characteristics,complications,comorbidities,and metabolic and hematology parameters with albuminuric and non-albuminuric CKD patterns were analyzed.The urinary excretion of nephrin and podocin,two podocytespecific markers,and WAP-four-disulfide core domain protein 2(WFDC-2),a marker of tubulointerstitial fibrosis,was determined by ELISA in comparison with healthy controls.RESULTS Non-albuminuric CKD was associated with age≥65 years(P=0.0001),female sex(P=0.04),diabetes duration≥15 years(P=0.0009),and the use of diuretics(P=0.0005).Male sex(P=0.01),smoking(P=0.01),waist-to-hip ratio>1.0(P=0.01)and hemoglobin A1c(HbA1c)>8.0%(P=0.005)were risk factors for elevated albuminuria not accompanied by a decrease in estimated glomerular filtration rate(eGFR).Duration of diabetes≥15 years and the use of calcium channel blockers were risk factors for albuminuria with decreased eGFR(both P=0.01).In multivariate logistic regression analysis,age,HbA1c,female sex and diuretics were significant predictors for reduced eGFR,while waist-to-hip ratio,HbA1c and male sex were associated with elevated urinary albumin-to-creatinine ratio(UACR).Excretion of nephrin and podocin was increased in patients with albuminuria,regardless of decline in renal function(P<0.001),correlating positively with UACR.The urinary excretion of WFDC-2 was markedly higher in men than in women(P<0.000001).Men with T2D demonstrated increased WFDC-2 levels independently of the CKD pattern(all P<0.05).In T2D women,WFDC-2 excretion was increased in those with reduced renal function(P≤0.01),correlating negatively with eGFR.CONCLUSION The data provide further evidence that albuminuric and non-albuminuric CKD phenotypes correspond to different pathways of diabetic kidney disease progression.

Behavioral Risk Factors for Chronic Non-Communicable Diseases in Adults and Elderly People in the City of Ribeirão Preto—SP

Aims: to analyze the presence and simultaneity of behavioral risk factors for chronic non-communicable disease (NCD) in adults and the elderly. Methods: quantitative, cross-sectional and observational study. Healthy and unhealthy eating are classified according to the frequency of food consumption. Smoking is expressed by the percentage of smokers. Harmful alcohol consumption by the percentage of individuals who consumed alcoholic beverages at least once in the last 30 days. Classification of the level of physical inactivity required to practice at least 150 minutes of physical activity. Results: the sample constituted 719 people, 535 adults and 184 elderly. The behavioral risk factor reported by most adults 499 (93.3%) and elderly 156 (84.8%) was unhealthy eating. Frequency 72% higher of smoking, four times higher of harmful alcohol consumption and 10% higher of unhealthy food among adults when compared to the elderly. The simultaneity between risk factors was 39% greater in adults than in the elderly. Discussion: risk factors evaluated in this study are key aspects of the development of NCDs. Adults have 2.43 times the chance of presenting two risk factors and 7.73 times the chance of presenting three in relation to the elderly. Conclusion: To achieve more effective and differentiated results, knowing and directing measures to control behavioral risk factors, whether isolated or concurrent, requires specific knowledge.

Epidemiologic risk factors for patients admitted with chronic pancreatitis and pancreatic ductal adenocarcinoma in the United States

BACKGROUND Epidemiological studies of chronic pancreatitis(CP)and its association with pancreatic ductal adenocarcinoma(PDAC)are limited.Understanding demographic and ethno-racial factors may help identify patients at the highest risk for CP and PDAC.AIM To evaluate the ethno-racial risk factors for CP and its association with PDAC.The secondary aim was to evaluate hospitalization outcomes in patients admitted with CP and PDAC.METHODS This retrospective cohort study used the 2016 and 2017 National Inpatient Sample databases.Patients included in the study had ICD-10 codes for CP and PDAC.The ethnic,socioeconomic,and racial backgrounds of patients with CP and PDAC were analyzed.RESULTS Hospital admissions for CP was 29 per 100000,and 2890(0.78%)had PDAC.Blacks[adjusted odds ratio(aOR)1.13],men(aOR 1.35),age 40 to 59(aOR 2.60),and being overweight(aOR 1.34)were significantly associated with CP(all with P<0.01).In patients with CP,Whites(aOR 1.23),higher income,older age(aOR 1.05),and being overweight(aOR 2.40)were all significantly associated with PDAC(all with P<0.01).Men(aOR 1.81)and Asians(aOR 15.19)had significantly increased mortality(P<0.05).Hispanics had significantly increased hospital length of stay(aOR 5.24)(P<0.05).CONCLUSION Based on this large,nationwide analysis,black men between 40-59 years old and overweight are at significantly increased risk for admission with CP.White men older than 40 years old and overweight with higher income were found to have significant associations with CP and PDAC.This discrepancy may reflect underlying differences in healthcare access and utilization among different socioeconomic and ethno-racial groups.

A Clinical Analysis to Detect Risk Factors of Chronic Subdural Hematoma Recurrence

Introduction: The etiology of recurrence of chronic subdural hematoma (CSDH) after surgical evacuation has not been completely understood until now, but several risk factors for recurrence have been reported. Meanwhile, the definitive risk factors have not been defined until now. Aim of Study: Analyze the potential risk factors, and emphasize preoperative, operative and post-operative ones for CSDH recurrence. Patients and Methods: This study is a prospective randomized clinical trial study including 82 patients with symptomatizing CSDH who underwent burr holes procedure and irrigation with closed system drainage for CSDH at Neurosurgical Department—Assuit University Hospital from July 2016 to July 2018. The possible factor studied for recurrence included age, hypertension, diabetes mellitus, liver diseases, Hemoglobin (Hb) level, prothrombin concentration and time (PC and PT), hematoma thickness and internal architecture, number of burr holes and position of drain, duration of drainage, amount of drainage and presence of postoperative residual hematoma on follow up CT brain. Multiple logistic regression analysis is used to assess the predictors of recurrence. Results: This study included 70 males and 12 females. The mean age was 58.9 years (range 34 - 93 years). 6 patients presented with recurrent CSDH. Age above 60 years, Hypertension, Diabetes mellitus (DM), prolong PT, separated and trabecular internal architecture of hematoma, and the thickness of hematoma more than 20 mm in pre-operative CT and postoperative residual hematoma were statistically significant factors for recurrence of CSDH. Conclusion: This information might be helpful in detecting patients with possible high incidence of recurrence and directing for close follow ups and acts that may reduce the incidence of recurrence.

Mortality-Related Risk Factors in Patients with Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension. The Importance of Response to Treatment

Background: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are serious diseases with similar pathophysiologic aspects. The prognosis of patients with these conditions is highly uncertain, particularly incident cases. Methods: A Cox proportional hazards model was applied to a group of 85 patients (81% women, mean age 52 (18 - 82) years) with PAH (80%) and non-surgical CTEPH (20%) to evaluate risk factors for mortality. The following variables were included in the model: age, etiology, baseline 6-minute walk test (6 mWT), cardiac index, and improvement in the 6 mWT following initiation of first medical treatment. Results: In the multivariate analysis, the response to treatment, assessed by an improvement on the 6 mWT, was the most relevant prognostic factor in these patients (RR, 4.832 (95% CI, 1.888 - 12.364);p = 0.001). The remaining variables studied in this model had less influence on the prognosis: age > 50 years (RR, 0.744 (95% CI, 0.26 - 2.133);p = 0.582);etiology of connective tissue disease-associated PAH (RR, 3.145 (95% CI, 0.995-9.946);p = 0.051) or CTEPH (RR, 0.654 (95% CI, 0.179 - 2.387);p = 0.521) with respect to idiopathic PAH;baseline 6 mWT (RR, 1.173 (95% CI, 0.599 - 4.895);p = 0.315);or cardiac index (RR, 2.295 (95% CI, 0.793 - 6.642);p = 0.125). Conclusions: There is a high degree of uncer-tainty regarding the prognosis of PAH and CTEPH at the start of appropriate treatment. Our results support the idea that the initial treatment response is of paramount importance as prognostic factor in these patients.

Prevalence of Risk Factors for Chronic Non-Communicable Diseases to the National Teaching Hospital “HKM” of Cotonou

Background: In 2008 Non-communicable diseases (NCDs) were responsible for 63% of deaths worldwide and 80% of these deaths occurred in developing countries. Four of them were responsible for more than 80% of mortality from NCDs, which were cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes. They shared the same risk factors. Objective: To determine the prevalence of NCD risk factors in patients admitted to consult in the outpatient unit of the National Teaching Hospital of Cotonou. Patients and Methods: This was a transversal, descriptive and analytical study which took place from 15 June 2011 to 16 September 2011. It focused on 1000 subjects found after a recruitment of all patients coming to consult during the study period. The collection technique was a questionnaire followed by physical measures (weight, height, blood pressure and waist) and biological measures (fasting glucose and cholesterol). The data were analyzed with the software Epi-3.3.2 info. Results: The mainly prevalent behavioural risk factors were smoking (10.2%), alcohol consumption (60.3%), insufficient intake of fruits and vegetables (84.2%), and physical inactivity (57.6%). The prevalent physical risk factors were hypertension (47.4%), obesity (27.5%), and overweight (35.3%). The prevalent biological risk factors were diabetes (28.5%), and hypercholesterolemia (10.4%). The level of cardiovascular risk was higher than 40% in 81 people (8.1%). Conclusion: This study shows the importance of risk factors for NCDs in outpatient Unit in the National Teaching Hospital of Cotonou.

Risk factors and prognosis of critically ill cancer patients with postoperative acute respiratory insufficiency

BACKGROUND:This study aimed to investigate the risk factors and outcome of critically ill cancer patients with postoperative acute respiratory insufficiency.METHODS:The data of 190 critically ill cancer patients with postoperative acute respiratory insufficiency were retrospectively reviewed.The data of 321 patients with no acute respiratory insufficiency as controls were also collected.Clinical variables of the first 24 hours after admission to intensive care unit were collected,including age,sex,comorbid disease,type of surgery,admission type,presence of shock,presence of acute kidney injury,presence of acute lung injury/acute respiratory distress syndrome,acute physiologic and chronic health evaluation(APACHE Ⅱ) score,sepsis-related organ failure assessment(SOFA),and PaO_2/FiO_2 ratio.Duration of mechanical ventilation,length of intensive care unit stay,intensive care unit death,length of hospitalization,hospital death and one-year survival were calculated.RESULTS:The incidence of acute respiratory insufficiency was 37.2%(190/321).Multivariate logistic analysis showed a history of chronic obstructive pulmonary diseases(P=0.001),surgeryrelated infection(P=0.004),hypo-volemic shock(P<0.001),and emergency surgery(P=0.018),were independent risk factors of postoperative acute respiratory insufficiency.Compared with the patients without acute respiratory insufficiency,the patients with acute respiratory insufficiency had a prolonged length of intensive care unit stay(P<0.001),a prolonged length of hospitalization(P=0.006),increased intensive care unit mortality(P=0.001),and hospital mortality(P<0.001).Septic shock was shown to be the only independent prognostic factor of intensive care unit death for the patients with acute respiratory insufficiency(P=0.029,RR:8.522,95%CI:1.243-58.437,B=2.143,SE=0.982,Wald=4.758).Compared with the patients without acute respiratory insufficiency,those with acute respiratory insufficiency had a shortened one-year survival rate(78.7%vs.97.1%,P<0.001).CONCLUSION:A history of chronic obstructive pulmonary diseases,surgery-related infection,hypovolemic shock and emergency surgery were risk factors of critically ill cancer patients with postoperative acute respiratory insufficiency.Septic shock was the only independent prognostic factor of intensive care unit death in patients with acute respiratory insufficiency.Compared with patients without acute respiratory insufficiency,those with acute respiratory insufficiency had adverse shortterm outcome and a decreased one-year survival rate.

Risk factors and outcome of bacterial infections in cirrhosis

Viable and non-viable pathological bacterial translocation promote a self-perpetuating circle of dysfunctional immune activation and systemic inflammation facilitating infections and organ failure in advanced cirrhosis.Bacterial infections and sepsis are now recognized as a distinct stage in the natural progression of chronic liver disease as they accelerate organ failure and contribute to the high mortality observed in decompensated cirrhosis.The increasing knowledge of structural,immunological and hemodynamic pathophysiology in advanced cirrhosis has not yet translated into significantly improved outcomes of bacterial infections over the last decades.Therefore,early identification of patients at the highest risk for developing infections and infectionrelated complications is required to tailor the currently available measures of surveillance,prophylaxis and therapy to the patients in need in order to improve the detrimental outcome of bacterial infections in cirrhosis.

Risk Factors among Greenhouse Farmers in Gaza Strip

Greenhouse farmers are exposed to many risk factors during work. This paper characterized the risk factors and discussed their health impacts among greenhouse farmers. Risk factors under greenhouse conditions emerged from pesticide application and greenhouse gas emission from soil during day. Risk factors among farmers were determined by recording toxicity symptoms, acute and chronic obstructive pulmonary disease (COPD). This study targeted 67 greenhouses in Gaza Strip and found 169 farmers doing many agricultural activities without protective clothes. We documented nine highly toxic insecticides and five moderately toxic fungicides being applied for insect and fungal control. A large number of farmers (55%) revealed that they visited respiratory health clinic quite two to three times a month immediately after insecticide application. About 8.88% (n = 15) of farmers stated that they had unrecoverable lung disease due to working in greenhouses during winter season. Personal health records of farmers showed variety of cholinergic symptoms, severe reduction on acetyl choline esterase activity (ACHE), many cases of COPD and some pneumonia cases. Classification of farmers according to risk factors indicates that 18% of farmers are at high risk due to extreme to insecticides. It is recommended to seasonally investigate the activity of ACHE of greenhouse farmers and to routinely check their chests and lungs to avoid any potential health risk factors due to works in greenhouse environment.

Liver histological changes in untreated chronic hepatitis B patients in indeterminate phase

BACKGROUND Studies with large size samples on the liver histological changes of indeterminate phase chronic hepatitis B(CHB)patients were not previously conducted.AIM To assess the liver histological changes in the indeterminate phase CHB patients using liver biopsy.METHODS The clinical and laboratory data of 1532 untreated CHB patients were collected,and all patients had least once liver biopsy from January 2015 to December 2021.The significant differences among different phases of CHB infection were compared with t-test,and the risk factors of significant liver histological changes were analyzed by the multivariate logistic regression analysis.RESULTS Among 1532 untreated CHB patients,814(53.13%)patients were in the indeterminate phase.Significant liver histological changes(defined as biopsy score≥G2 and/or≥S2)were found in 488/814(59.95%)CHB patients in the indete-rminate phase.Significant liver histological changes were significant differences among different age,platelets(PLTs),and alanine aminotransferase(ALT)subgroup in indeterminate patient.Multivariate logistic regression analysis indicated that age≥40 years old[adjust odd risk(aOR),1.44;95%confidence interval(CI):1.06-1.97;P=0.02],PLTs≤150×10^(9)/L(aOR,2.99;95%CI:1.85-4.83;P<0.0001),and ALT≥upper limits of normal(aOR,1.48;95%CI:1.08,2.05,P=0.0163)were independent risk factors for significant liver histological changes in CHB patients in the indeterminate phase.CONCLUSION Our results suggested that significant liver histological changes were not rare among the untreated CHB patients in indeterminate phase,and additional strategies are urgently required for the management of these patients.

Whether chronic bronchitis is an independent risk factor for cerebral infarction in the elderly 1:1 case paired study

BACKGROUND： The inflammatory reaction already becomes an important risk factor of causing acute cerebral infarction; however, the correlation between chronic bronchitis and senile cerebral infarction is still unclear. OBJECTIVE： To study whether the chronic bronchitis is the risk factor for senile cerebral infarction. DESIGN： 1 ： 1 pair, case contrast, and risk factor study. SETTINGS： Department of Respiratory Medicine, Third Hospital of Tangshan; Department of Neurology, Affiliated Hospital of North China Coal Medical College. PARTICIPANTS： A total of 147 patients with acute cerebral infarction who were regarded as case group were selected from Department of Neurology, the Third Hospital of Tangshan from January 2004 to December 2006. All patients met the diagnostic criteria of the Fourth National Cerebrovascular Diseases Meeting. There were 87 males and 60 females, and their ages ranged from 65 to 83 years. Based on 1 ： 1 pair study, another 147 subjects without cerebrovascular disease were regarded as control group. Except the diseases about infection, there were 73 males and 74 females, and their ages ranged from 62 to 81 years. All subjects provided the confirm consent and agreed with the coordinate experiment. METHODS： ①Questionnaire of risk factor of cerebral infarction was designed to measure the following items： chronic bronchitis, hypertension, diabetes mellitus, hyperlipemia, coronary heart disease, primary cerebral infarction/transient ischemic attack and history of smoking. ②Cerebral infarction was regarded as the dependent variance, while chronic bronchitis, hypertension, diabetes mellitus, hypedipemia, primary cerebral infarction/transient ischemic attack, coronary heart disease and smoking were regarded as the independent variance for multiple regression analysis, MAIN OUTCOME MEASURES： Risk factors of senile cerebral infarction. RESULTS： All 147 patients with acute cerebral infarction and 147 subjects without cerebrovascular diseases were involved in the final analysis. ①Risk factor analysis of senile cerebral infarction： There were no significant differences in age, hyperlipemia and history of smoking between the two groups （P 〉 0.05）. But, chronic bronchitis, diabetes mellitus, hypertension, cerebral infarction/transient ischemic attack and history of coronary heart disease were higher in the case group than those in the control group （33.6% vs. 19.0%, 38.8% vs. 23.3%, 54.3% vs. 36.2%, 29.3% vs. 17.2%, 44.0% vs. 29.3%, P 〈 0.05- 0.01）. ②Multiple Logistic regression analysis of risk factor of senile cerebral infarction Hyperlipemia, smoking and coronary heart disease were not correlated with cerebral infarction （P 〉0.05）, but chronic bronchitis, hypertension, diabetes mellitus and cerebral infarction/transient ischemic attack were risk factors for senile cerebral infarction （OR =2.47, 2.28, 2.18, 2.01, P 〈 0.05 - 0.01）. CONCLUSION： The chronic bronchitis mac become an independent risk factor senile cerebral infarction.
