The objective of the study was to determine the potential impact of Purdue improved cowpea storage (PICS) technology on the income of users in north central states of Nigeria. A multi-stage sampling procedure involved selection of 3 Local Government Areas (LGAs) each from 18 senatorial districts of six states, 108 villages. Thereafter 2,220 cowpea PICs stakeholders comprising 1,240 farmers and 960 traders were randomly selected by balloting technique. The study used primary data and structured questionnaire to interview users and non-users of PICS bag. Descriptive statistics, double difference estimator, propensity score matching (PSM) and logic model were used to analyze the data. The result showed a positive mean difference of ₦1,205.12 per 50 kg bag (p<0.01) in income between users and non-users before and after adoption of PICS technology. The result of logit model revealed that variables age, education status, employment status, income and quantity of cowpea used in the analysis were significant at different level of probability. The PSM adjusted with constant coefficient value of 1.000 was statistically significant at 1% level. Thus, the PICS technology was a better strategy adopted by farmers/traders to increase their income and improve their standard of living. Since majority of farmers and traders are young and educated, trainings, workshops and sensitization should be encouraged. This can be effectively done through Agricultural Development Programmes (ADP), Non-Governmental Organizations (NGOs) and attending farmer’s stakeholders meeting for sensitization. Keywords — Cowpea, impact, Propensity Score Matching (PSM), Purdue.

Abstract The purpose of this study is to explore the effect of employment on depression and life satisfaction among old-aged. Using 12th (2017) wave and 13th (2018) wave of Korean Welfare Panel Study (KoWePS), three stages of analyses were conducted. First, through propensity score matching (PSM) method, sample with similar propensity scores was matched between the group that did not work in 12th wave but worked in 13th wave (experimental group, N=180), and the group that did not work in 12th and 13th wave (comparative group, N=180). Second, the matched sample was used to conduct multiple regression analysis with the group dummy variable (experimental group, comparative group) as an independent variable, and depression and life satisfaction as the dependent variables. Third, combined model of propensity score matching (PSM) and double difference (DD) method was conducted to more appropriately derive the net effect of employment. The results of multiple regression after propensity matching showed that employment had a positive effect on reducing depression (B= -1.70, p&lt; .01) and increasing life satisfaction (B= .12, p&lt; .01) in old-aged. Furthermore, in combined model of PSM and DD, life satisfaction was improved when employed compared to non-employed (B= .15, p&lt; .05). The results of this study are meaningful in that the meaning of employment in old-aged is more clearly derived by solving selection bias and endogenous problems. Also, this study may provide reference for establishing welfare policies related to employment among old-aged.

Abstract Background Adoption of improved agricultural technologies remains to be a promising strategy to achieve food security and poverty reduction in many developing countries. However, there are limited rigorous impact evaluations on the contributions of such technologies on household welfare. This paper investigates the impact of improved agricultural technology use on farm household income in eastern Ethiopia. Methods Primary data for the study was obtained from a random sample of 248 rural households, 119 of which are improved technology users and the rest are non-users. The research employed the Propensity Score Matching (PSM) procedure to establish the causal relationship between adoption of improved crop and livestock technologies and changes in farm income. Results Results from the econometric analysis show that households using improved agricultural technologies had, on average, 23,031.28 Birr (Birr is the official currency of Ethiopia. The exchange rate according to the National Bank of Ethiopia (NBE) was 1 USD = 27.6017 Birr on 04 October 2018.) higher annual farm income compared to those households not using such technologies. Our findings highlight the importance of promoting multiple and complementary agricultural technologies among rural smallholders. Conclusions We suggest that rural technology generation, dissemination and adoption interventions be strengthened. Moreover, the linkage among research, extension, universities and farmers needs to be enhanced through facilitating a multistakeholders innovation platforms.

Abstract Background Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. Methods We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan–Meier analysis. Results In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7–61.2], 62.3 months (CI: 42.1–72.9), and 36.2 months (CI: 15.4–56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. Conclusion The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

Introduction: There are no randomized controlled trials that compared the outcomes of leadless pacemaker (L-PPM) implantation with transvenous pacemaker (TV-PPM) and there is scarcity of data on real world outcomes. Methods: We queried National Inpatient Sample to identify all adult patients who had primary discharge diagnosis of conduction disorders or tachy-arrhythmias and excluded patients who had a concomitant procedure for valve replacement, coronary artery bypass grafting, ablation and/or cardiac implantable electronic device removal so that complications can be attributed to the pacemaker implantation. We included only procedures from November 2016 to December 2017 as Micra was the only available L-PPM during that period. For the comparison cohort we selected patients, during the same time period, who had a procedure code for single chamber pacemaker implantation in conjunction with right ventricular lead placement. We performed 1:1 propensity score matching and the variables used for matching are marked with asterisk in Table 1. All the codes used to identify complications has been previously validated from the Micra Post-approval registry and Coverage with Evidence Study. Results: Total of 1,305 patients for L-PPM and 13,905 patients in the TV-PPM group were included. Baseline characteristics with standardized mean difference before and after matching are shown in Table 1. Briefly, patients in L-PPM group were younger but had higher co-morbidities compared to TV-PPM group. The complications before and after matching are shown in Table 2. Conclusions: In conclusion, we found no significant difference between in-hospital complications after propensity score matching, with the exception of deep venous thrombosis. There was no difference between length of stay but cost for L-PPM was significantly higher. In this real-world analysis, we found that the leadless PPM implantation is safe in comparison to transvenous PPM.

Consumers’ preference for local rice determines its demand. Therefore, the study was carried out to analyze consumers’ preference for local rice among households in Ekiti State. A multi-stage sampling procedure was used to select respondents for this study. A total of 240 women were randomly selected from three Local Government Areas (LGAs) in the State. Primary data were obtained with the use of a well-structured interview schedule. Data collected were analyzed using descriptive statistics as well as inferential statistic like logistic regression. The mean age of the respondents was 38 years and more than half (53.3%) of the respondents were females. Most (70.0%) of the respondents had a mean family size of 7 persons. Most (87.0%) preferred local rice and factors influencing consumers’ preference for local rice include good nutritional value, quality of rice and good taste. Local rice was very much preferred by the respondents. Logistic regression shows that significant influence exists between price, taste, availability of rice and presence of particles and preferred choice of rice. Therefore, efforts should be made by the government to formulate price control policy on local rice for its affordability by the consumers and there should be improvement on processing technology of local rice to eliminate presence of particles for improved quality and good taste to enhance the consumers’ preference for choice of rice. Also, the government should support farmers through provision of incentives and credit facilities so as to produce more local rice for its availability all year round.

The study was undertaken to examine the socio-economic profiles of women participated in farms and rice mills activities; to examine contribution of women to household income which reducing their poverty; to identify the factors influencing the level of family income in farms and rice mills labourers; and to identify the problems and constraints of farms and rice mills. Bochagonj Upazila of Dinajpur district was selected purposively for the study considering the availability of large number of farm and rice mill labourers. Sixty samples of each category have been selected by random sampling procedure and primary data were collected by direct interview through a pre-tested survey schedule. The educational status, land holding and other household assets position were improved due to the women’s contribution to overall family income. Patterns of family expenditure remained same before and after the women involvement in farm and rice mill works but increased over time that indicated some significant changes in the level of poverty of the households. Age of the respondents, family size, land holding, number of earning members and respondents’ income contributed significantly to the variability of income and employment. Major problems were nature of the work and the variation in the salary level between male and female labourers. Finally, women contributed a small amount but a significant proportion of their family income and the socioeconomic status of the women farm and rice mill labourers should be improved through direct participation in income generating activities by reducing the male and female discriminations.

In this study, we examined the association between participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and breastfeeding outcomes before and after the 2009 revisions. Four-thousand-three-hundred-and-eight WIC-eligible children younger than 60 months were included from the 2005–2014 National Health and Nutrition Examination Survey (NHANES). We compared two birth cohorts with regard to their associations between WIC participation and being ever-breastfed and breastfed at 6 months. We estimated the average effect of the treatment for the treated to assess the causal effect of WIC participation on breastfeeding based on propensity score matching. The results showed that WIC-eligible participating children born between 2000 and 2008 were significantly less likely than WIC-eligible nonparticipating children to ever receive breastfeeding (p < 0.05) or to be breastfed at 6 months (p < 0.05). Among children born between 2009 and 2014, WIC-eligible participating children were no longer less likely to ever receive breastfeeding compared to WIC-eligible nonparticipating children; the gap remained in breastfeeding at 6-months (p < 0.05). The disparities in prevalence of ever breastfed between WIC-eligible participants and nonparticipants have been eliminated since the 2009 WIC revision. More efforts are needed to improve breastfeeding persistence among WIC-participating mother–infant dyads.

Abstract Background: Preoperative anaemia is a common clinical situation that was proved to be associated with severe outcomes in major surgery but not pancreatic surgery alone. We aimed to study the impact of preoperative anaemia on morbidity and mortality in patients undergoing open pancreaticoduodenectomy by using propensity score matching (PSM) to balance the basal data and reduce bias. Methods: Consecutive patients undergoing open pancreaticoduodenectomy with complete record of preoperative haemoglobin at two pancreatic centers in China between 2015 to 2019 were analysed. Haemoglobin less than 12g/dl for male and 11g/dl for female were defined as anaemia in Chinese population. Clinical and economic outcomes were compared before and after propensity score matching (PSM). Logistic regression analysis was used to assess correlation between variables and anaemia. Results: The unmatched initial cohort consist of 517 patients. 148 cases (28.6%) were diagnosed as anaemia at admission, and no case received preoperative blood transfusion or anti-anaemia therapy. After PSM, 126 cases were in each group. The rate of severe postoperative complications was significantly higher in anaemia group than in normal group (43.7% versus 27.0%, P=0.006), among which prevalence of clinically relevant postoperative pancreatic fistula (31.0% versus 15.9%, P=0.005) and cardiac and cerebrovascular events (4.0% versus 0.0%, P=0.024) were most significant. It costed more in the anaemia group (26958.2±21671.9 versus 20987.7±10237.9 USD, P=0.013). Among all patients, multivariate analysis showed that preoperative obstructive jaundice [OR 1.813, 95%CI (1.206-2.725), P=0.004] and pancreatic ductal adenocarcinoma [OR 1.861, 95%CI (1.178-2.939), P=0.008] were predictors of anaemia. Among paired patients, preoperative anaemia [OR 2.593, 95%CI (1.481-5.541), P=0.001] and malignant pathology [OR 4.266, 95%CI (1.597-11.395), P=0.004] were predictors of postoperative severe complications.Conclusions: Preoperative anaemia is a predictor of cacoethic postoperative outcomes following open pancreatoduodenectomy and needs identified and treated.

Abstract Background The Omicron SARS-CoV-2 variant is rapidly spreading in the US since December 2021 and is more contagious than earlier variants. Currently, data on the severity of the disease caused by the Omicron variant compared with the Delta variant is limited. Here we compared 3-day risks of emergency department (ED) visit, hospitalization, intensive care unit (ICU) admission, and mechanical ventilation in patients who were first infected during a time period when the Omicron variant was emerging to those in patients who were first infected when the Delta variant was predominant. Method This is a retrospective cohort study of electronic health record (EHR) data of 577,938 first-time SARS-CoV-2 infected patients from a multicenter, nationwide database in the US during 9/1/2021-12/24/2021, including 14,054 who had their first infection during the 12/15/2021-12/24/2021 period when the Omicron variant emerged (Emergent Omicron cohort) and 563,884 who had their first infection during the 9/1/2021-12/15/2021 period when the Delta variant was predominant (Delta cohort). After propensity-score matching the cohorts, the 3-day risks of four outcomes (ED visit, hospitalization, ICU admission, and mechanical ventilation) were compared. Risk ratios, and 95% confidence intervals (CI) were calculated. Results Of 14,054 patients in the Emergent Omicron cohort (average age, 36.4), 27.7% were pediatric patients (<18 years old), 55.4% female, 1.8% Asian, 17.1% Black, 4.8% Hispanic, and 57.3% White. The Emergent Omicron cohort differed significantly from the Delta cohort in demographics, comorbidities, and socio-economic determinants of health. After propensity-score matching for demographics, socio-economic determinants of health, comorbidities, medications and vaccination status, the 3-day risks in the Emergent Omicron cohort outcomes were consistently less than half those in the Delta cohort: ED visit: 4.55% vs. 15.22% (risk ratio or RR: 0.30, 95% CI: 0.28-0.33); hospitalization: 1.75% vs. 3.95% (RR: 0.44, 95% CI: 0.38-0.52]); ICU admission: 0.26% vs. 0.78% (RR: 0.33, 95% CI:0.23-0.48); mechanical ventilation: 0.07% vs. 0.43% (RR: 0.16, 95% CI: 0.08-0.32). In children under 5 years old, the overall risks of ED visits and hospitalization in the Emergent Omicron cohort were 3.89% and 0.96% respectively, significantly lower than 21.01% and 2.65% in the matched Delta cohort (RR for ED visit: 0.19, 95% CI: 0.14-0.25; RR for hospitalization: 0.36, 95% CI: 0.19-0.68). Similar trends were observed for other pediatric age groups (5-11, 12-17 years), adults (18-64 years) and older adults (>= 65 years). Conclusions First time SARS-CoV-2 infections occurring at a time when the Omicron variant was rapidly spreading were associated with significantly less severe outcomes than first-time infections when the Delta variant predominated.
