ABSTRACT
Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.
ABSTRACT
Recent pandemic of vitamin D deficiency is co-existing with type II diabetes mellitus pandemic. Even in India, vitamin D insufficiency/deficiency is common among individuals with pre-diabetes. If correlation can be established between these two and risk of impaired glucose tolerance (IGT) or diabetes can be predicted based on serum vitamin D status, much early detection of pre-diabetes or diabetes will be possible and preventive measures can be taken. Not too many studies have been done in this context, especially in North Bengal region of West Bengal, India. We wanted to evaluate the correlation between vitamin D status and glycaemic status of individual and predict the risk of impaired glucose tolerance depending on vitamin D, independent of other factors.METHODSAfter ethical clearance and informed consent, 430 study subjects were interviewed, examined, blood sample collected and tested. Data was entered in Microsoft Excel 2007 and analysed using appropriate software. Correlation and multinomial regression analysis were done.RESULTSMean ± SD of serum 25(OH) D level is found to be 21.53±7.06 ng/ml among a total of 430 study participants. 41.86% of participants were found to be with insufficient vitamin D status. Pearson’s correlation between serum 25(OH) D level and post prandial blood sugar is found to be strongly negative while Spearman’s correlation between vitamin D status and post prandial glycaemic status of individuals is found to be strongly positive. If vitamin D status changes from “Sufficient” to “Insufficient” or “Deficient”, risk of IGT increases by 17 times and 16.3 times respectively.CONCLUSIONSStrong positive correlation exists between vitamin D status and glycaemic status of individuals. Estimation of 25(OH) D level may be used as a screening test for detection of risk of IGT.
ABSTRACT
Objective: To identify the key process parameters of the Chinese materia medica (CMM) production process by using grey relation analysis (GRA) method. Methods: Taking Lonicerae Japonicae Flos and Artemisiae Annuae Herba extraction section of Reduning Injection as an example, GRA was adopted to calculate and compare the influence of the process parameters on the quality index. Meanwhile, analytic hierarchy process (AHP) combined with Spearman rank correlation analysis was used to validate mutually. Results: According to GRA Results:, the relative importance of process parameters was ranked as follows: average volume flow rate of extraction (X4) > pH after acid adjustment (X2) > the paste temperature of extracting concentration (X7) > alcohol precipitation concentrated extract weight (X1) > hydrochloric acid weight (X3) > extraction time (X6) > relative standard deviation of flow rate (X5). The correlation coefficient between the order by GRA and that by AHP was 0.893. According to the importance of process parameters, the average volume flow rate of extraction, the pH after acid adjustment, and the paste temperature of extracting concentration were identified as the key process parameters. Conclusion: The Results: obtained in this study show the feasibility of GRA in selecting key process parameters, which can provide theoretical reference for the establishment of prediction model as well as online feedback regulation.
ABSTRACT
@#The objectives of this study is to evaluate the suitability of full cup test (FCT), numeric pain rating scale (NPRS), and visual analogue scale (VAS) to assess pain after surgical removal of lower third molar and to identify which of these three pain scales is the easiest to use. A total of 50 patients, age between 18 to 30 years who underwent minor oral surgery for removal of impacted third molar were sampled in Faculty of Dentistry, University of Malaya. The patients were provided with forms containing three pain scales and they were required to mark each pain scales – FCT, NPRS and VAS daily for three consecutive post-operative days. The forms were collected a week later when patients came back for review. The validity between NPRS with VAS, FCT with NPRS and FCT with VAS were tested using Spearman rank correlation coefficient. Results showed that the correlation coefficient values for each pair were very high and significant. The findings when comparing Day 1, Day 2 and Day 3 and the combination for those three days showed no significant differences. No evidences indicated that the findings for Day 1 were more superior in comparison with other days. In conclusion, FCT was as valid as NPRS and VAS. The pain scale which was claimed to be the easiest to use by patients was NPRS, followed by FCT and VAS. However, further studies are needed to investigate the reliability and sensitivity of FCT.
ABSTRACT
Objective: The present study is carried out to explore the factors associated with phobia, to compare the severity of phobias between cases (mentally ill women) and controls (never mentally ill) and to identify the factors predicting different types of phobias. Methods: A cross sectional study among female cases and controls is conducted. A sample of 150 female respondents including 30 cases and 120 controls is taken to assess the point prevalence of different types of phobias. The Social Phobia Inventory (SPIN) questionnaire was used to identify social phobia on a very severe, severe, moderate, mild and no phobia scale. Pearson chi square and spearman’s rank correlation was applied to assess the associations among different factors and various types of phobias. Results: The most common phobia among the population was Agrizoophobia (93%) followed by Agoraphobia (81%) and Taphophobia (74%). Among cases, age is was associated with Agoraphobia and Acrophobia, marital status of the respondent was associated with Agoraphobia and Acrophobia, marital status of father is associated with social phobia and Aichmophobia, traumatic event was associated with Mysophobia while family income was associated with Acrophobia and Aichmophobia. Age and Agoraphobia, and marital status and Acrophobia show significant results among controls. Multiple discriminant Analysis demonstrated that among cases, age was the best predictor in predicting Agoraphobia and Acrophobia , marital status of father was the best predictor in predicting Nosocomeophobia and traumatic event was the best predictor in predicting Mysophobia. Conclusion: Severe specific phobias are more prevalent among cases while controls suffer from mild specific phobias. Age, marital status of father and traumatic event in life are significant predictors for phobias.
