Association between Attention Deficit Hyperactivity Disorder and Suicide Attempts in Patients with Bipolar Disorder

Objective: The present study aimed to examine the association between ADHD and suicide attempts among adolescents with bipolar disorder. Method: Participants were 168 adolescents who fulfilled DSM-IV-TR criteria for bipolar disorder. They were divided into 2 groups: The first group of patients with bipolar disorder with a history of suicide attempts (n = 84) and the second group without a history of suicide attempts (n = 84). ADHD and other variables were analyzed using a chi-squared test and logistic regression model. Results: No significant difference was observed between the 2 groups in comorbidity of ADHD and other psychiatric disorders (P value > 0/05). In the logistic regression model, and after controlling for other factors, gender (OR = 3.9, CI 95%: 1.5-9.6) and history of sexual abuse (OR = 3.4; CI 95%: 1.06-11.3) were the only 2 factors associated with a history of suicide attempts. Conclusion: No significant association was found between ADHD and suicide attempts in adolescents with bipolar disorder.

Objectives: We assessed the factors relating to the prevention of the Novel Coronavirus Disease (COVID-19) for students at the University of Medicine and Pharmacy at Ho Chi Minh City, Vietnam. Methods: A cross-sectional study was performed in February and March 2020. A 21 item self-administered questionnaire on the knowledge, attitude, and practices regarding COVID-19 was collected from students of the first to the sixth year using the strategy of simple random sampling. The aim was to establish factors that relate to practices using Odds ratio (OR) and 95% confidence interval (95% CI) which were estimated by the logistic regression model, p-value <0.05 shows a significant difference. Results: Of the 551 students, 41.0% recorded responses indicating good practices toward prevention measures, while around half the students reported that they did not wash their hands for 20 full seconds (50.5%). The overall rate of good knowledge and positive attitude was 49.0% and 26.1%, respectively. When adjusted for all variables in the logistic regression model, a positive overall attitude was associated with good overall preventive practice; AOR = 1.72 (95% CI: 1.16 – 2.55). Furthermore, students mainly accessed information via social media and television (95.8% and 85.8%, respectively). Conclusions: There were only 41.0% recorded responses indicating good practices toward prevention measures. Besides, knowledge and attitudes about COVID-19 among students were inadequate. Further health education interventions should be focused to change bad hand-washing habits via mass media messages.

Abstract Objectives The objectives of this study were to examine the dietary salt-related knowledge, attitudes, and behaviors associated with the prevalence of hypertension among adults residing in rural Northern Thailand. Methods A cross-sectional study utilizing convenience sampling was administered in San Pa Tong District, Chiang Mai, Thailand. The one-on-one interview was conducted to assess subject's knowledge, attitudes, and behaviors relating to their dietary salt intake. Various food frequencies for foods high in salt were also measured. Each subject's blood pressure was measured twice before and after the interview. A logistic regression model was used in the analysis to determine potential hypertension risk factors. Results A total of 403 adults participated in the study. A majority of participants were female (73.2%), and the average age was 62.5 years old. Half of participants reported a family history of hypertension and 32% of participants were hypertensive. The major results from the logistic regression model indicated positive attitudes towards decreasing salt intake lead to a lower chance of becoming hypertensive (OR = 0.934). However, a family history of high blood pressure (OR = 1.417), a higher knowledge score about foods high in salt (OR = 1.254), daily use of Monosodium Glutamate (MSG) in food preparation (OR = 1.959) and buying outside food to eat at home (OR = 5.692) lead to a higher chance of becoming hypertensive. Conclusions Our findings suggest higher knowledge does not decrease the chance of becoming hypertensive. However, there is a positive association between hypertension and dietary salt-related behaviors among adults living in rural Thai communities. More specifically, salt-reduction interventions should focus on promoting home-cooked meal preparation with lower salt substitutes to MSG.

OBJECTIVE: The objective of this study was to test the hypothesis that the polarity of the first mood episode may be a marker for suicidal behavior, particularly the violent subtype. METHOD: One hundred and sixty-eight patients diagnosed with bipolar disorder (DSM-IV) were grouped according to type of first episode: depression or manic/hypomanic. Groups were compared for demographic and clinical variables. We performed logistic regression in order to test the association between first episode polarity and suicidal behavior. RESULTS: We found that depressed patients have a lifetime history of more suicide attempts. However, univariate analysis of number of suicide attempts showed that the best model fits the bipolar II subtype (mean square = 15.022; p = 0.010) and lifetime history of psychotic episodes (mean square = 17.359; p = 0.021). Subgrouping the suicide attempts by subtype (violent or non-violent) revealed that manic/hypomanic patients had a greater tendency toward attempting violent suicide (21.2 vs. 14.7%, X² = 7.028, p = 0.03). Multiple logistic regression analysis confirmed this result. CONCLUSION: Depressed patients had more suicide attempts over time, which could be explained by the higher prevalence of bipolar II subtype in this group, whereas manic/hypomanic patients had a lifelong history of more frequent violent suicide attempts, not explained by any of the variables studied. Our results support the evidence that non-violent suicide attempters and violent suicide attempters tend to belong to different phenotypic groups.

Object In Uganda, childhood hydrocephalus is common and difficult to treat. In some children, endoscopic third ventriculostomy (ETV) can be successful and avoid dependence on a shunt. This can be especially beneficial in Uganda, because of the high risk of infection and long-term failure associated with shunting. Therefore, the authors developed and validated a model to predict the chances of ETV success, taking into account the unique characteristics of a large sub-Saharan African population. Methods All children presenting with hydrocephalus at CURE Children's Hospital of Uganda (CCHU) between 2001 and 2007 were offered ETV as first-line treatment and were prospectively followed up. A multivariable logistic regression model was built using ETV success at 6 months as the outcome. The model was derived on 70% of the sample (training set) and validated on the remaining 30% (validation set). Results Endoscopic third ventriculostomy was attempted in 1406 patients. Of these, 427 were lost to follow-up prior to 6 months. In the remaining 979 patients, the ETV was aborted in 281 due to poor anatomy/visibility and in 310 the ETV failed during the first 6 months. Therefore, a total of 388 of 979 (39.6% and [55.6% of completed ETVs]) procedures were successful at 6 months. The mean age at ETV was 12.6 months, and 57.8% of cases were postinfectious in origin. The authors' logistic regression model contained the following significant variables: patient age at ETV, cause of hydrocephalus, and whether choroid plexus cauterization was performed. In the training set (676 patients) and validation set (303 patients), the model was able to accurately predict the probability of successful ETV (Hosmer-Lemeshow p value > 0.60 and C statistic > 0.70). The authors developed the simplified CCHU ETV Success Score that can be used in the field to predict the probability of ETV success. Conclusions The authors' model will allow clinicians to accurately identify children with a good chance of successful outcome with ETV, taking into account the unique characteristics and circumstances of the Ugandan population.

Abstract Introduction In low- and middle-income nations, acute respiratory infection (ARI) is the primary cause of morbidity and mortality. According to some studies, Ethiopia has a higher prevalence of childhood acute respiratory infection, ranging from 16 to 33.5%. The goal of this study was to determine the risk factors for acute respiratory infection in children under the age of five in rural Ethiopia. Methods A cross-sectional study involving 7911 children under the age of five from rural Ethiopia was carried out from January 18 to June 27, 2016. A two stage cluster sampling technique was used recruit study subjects and SPSS version 20 was used to extract and analyze data. A binary logistic regression model was used to identify factors associated with a childhood acute respiratory infection. The multivariable logistic regression analysis includes variables with a p-value less than 0.2 during the bivariate logistic regression analysis. Adjusted odds ratios were used as measures of effect with a 95% confidence interval (CI) and variables with a p-value less than 0.05 were considered as significantly associated with an acute respiratory infection. Results The total ARI prevalence rate among 7911 under-five children from rural Ethiopia was 7.8%, according to the findings of the study. The highest prevalence of ARI was found in Oromia (12.8%), followed by Tigray (12.7%), with the lowest frequency found in Benishangul Gumuz (2.4%). A multivariable logistic regression model revealed that child from Poor household (AOR = 2.170, 95% CI: 1.631–2.887), mother’s no education (AOR = 2.050,95% CI: 1.017–4.133), mother’s Primary education (AOR = 2.387, 95% CI:1.176–4.845), child had not received vitamin A (AOR = 1.926, 95% CI:1.578–2.351), child had no diarrhea (AOR = 0.257, 95% CI: 0.210–0.314), mothers not working (AOR = 0.773, 95% CI:0.630–0.948), not stunted (AOR = 0.663, 95% CI: 0.552–0.796), and not improved water source (AOR = 1.715, 95% CI: 1.395–2.109). Similarly, among under-five children, the age of the child, the month of data collection, anemia status, and the province were all substantially linked to ARI. Conclusions Childhood ARI morbidity is a serious health challenge in rural Ethiopia, according to this study, with demographic, socioeconomic, nutritional, health, and environmental factors all having a role. As a result, regional governments, healthcare staff, and concerned groups should place a priority on reducing ARI, and attempts to solve the issue should take these variables into account.

Objective : This study is to prove that there is a significant relationship between the absence of students participating in activities at school / on campus and the symptoms of primary dysmenorrhoea experienced during menstruation. Endometriosis is characterized as pain under the abdomen during menstruation. In addition, this study is also to obtain a profile of students and factors that influence primary dysmenorrhoea. A logistic regression model has been used to assess the main factors of dysmenorrhoea among these students.Methods : The study was conducted at the RSK Permata Hati Malang. A total of 123 students were randomly selected in this study. The factors observed were menarche, menstruation, menstruation period and blood loss volume and CA 125 level. From the logistic regression model, it was found that there were three factors that influence the occurrence of dysmenorrhoea among students, namely menarche, menstruation period and menstrual blood volume.Results: The Hosmer and Lemeshow test showed that the measurement model of CA 125 levels in endometriosis was appropriate (Chi squar test value was 2.847 with p-value = 0.416). Instead of Press. (3) and Eq. (4), it was found that the contributors to dismenortea were menstrual length, menstrual discharge and the beginning of menarche. By looking at the odds ratio it is found that the risk of students experiencing dysmenorrhoea is (i) 2.5 times higher for those with longer menstrual periods (ii) 3.7 times higher for those who have menstrual expenditure which is a little and (iii) three times higher for those who have mined it for more than 13 years.Conclusion: Significant CA 125 levels were obtained for students and students suffering from dysmenorrhoea. The study also found that the risk of getting dysmenorrhoea increased if students and students had menstrual periods longer than 35 days, menstrual expenditure levels were small and menarche was more than 13 years old.International Journal of Human and Health Sciences Vol. 05 No. 01 January’21 Page: 47-49

Introduction Internationally, countries have reacted to the COVID-19 outbreak by introducing key public health non-pharmaceutical interventions to protect vulnerable population groups. In response to COVID-19, the Government of Ethiopia has been taking a series of policy actions beyond public health initiatives alone. Therefore, this study was aimed to assess the applicability of basic preventive measures of the pandemic COVID-19 and associated factors among the residents of Guraghe Zone from 18th to 29th September, 2020. Methods Community based cross sectional study was conducted at Guraghe Zone from 18th to 29th September, 2020. Systematic random sampling method was applied among the predetermined 634 samples. Variables which had p-value less than 0.25 in bivariate analysis were considered as candidate for multivariable logistic regression model. P-value <0.05 was used as a cutoff point to determine statistical significance in multiple logistic regressions for the final model. Result In this study, 17.7% (95% CI: 14.7, 20.5) of the respondents apply the basic preventive measures towards the prevention of the pandemic COVID-19. In addition, being rural resident (AOR: 4.78,; 95%CI: 2.50, 8.90), being studied grade 1–8 (AOR: 3.70; 95%CI: 1.70, 7.90), being a farmer (AOR: 4.10; 95%CI: 1.25, 13.35), currently not married (AOR: 2.20, 95%CI: 1.24, 4.06), having family size 1-3(AOR: 6.50; 95%CI: 3.21, 3.35), have no diagnosed medical illness (AOR: 6.40; 95%CI: 3.85, 10.83) and having poor knowledge (AOR: 3.50; 95%CI: 1.60, 7.40) were factors which are statistically significant in multivariable logistic regression model. Conclusion Despite the application of preventive measures and vaccine delivery, the applicability of the pandemic COVID-19 preventive measures was too low, which indicate that the Zone is at risk for the infection. Rural residents, those who have lower educational level, farmers, non-marrieds, those who have lower family size, those who have diagnosed medical illnesses and those who have poor knowledge were prone to the infection with the pandemic COVID-19 due to the lower practice of applying the basic preventive measures. In addition, awareness creation should be in practice at all levels of the community especially lower educational classes and rural residents.

To conduct better research in hepatocellular carcinoma resection, this paper used 3D machine learning and logistic regression algorithm to study the preoperative assistance of patients undergoing hepatectomy. In this study, the logistic regression model was analyzed to find the influencing factors for the survival and recurrence of patients. The clinical data of 50 HCC patients who underwent extensive hepatectomy (≥4 segments of the liver) admitted to our hospital from June 2020 to December 2020 were selected to calculate the liver volume, simulated surgical resection volume, residual liver volume, surgical margin, etc. The results showed that the simulated liver volume of 50 patients was 845.2 + 285.5 mL, and the actual liver volume of 50 patients was 826.3 ± 268.1 mL, and there was no significant difference between the two groups (t = 0.425; P > 0.05). Compared with the logistic regression model, the machine learning method has a better prediction effect, but the logistic regression model has better interpretability. The analysis of the relationship between the liver tumour and hepatic vessels in practical problems has specific clinical application value for accurately evaluating the volume of liver resection and surgical margin.
