Objectives The aim was to compare the control of chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery (ESS), in patients with/without nonsteroidal anti-inflammatory drug exacerbated respiratory disease (NERD). Study Desing: A retrospective hospital-based sample of CRSwNP patients with/without NERD with follow-up. Setting Tertiary rhinology centers. Methods Electronic patient record data from 116 CRSwNP patients (46 with NERD and 70 without NERD) undergoing ESS during 2001–17 were studied. Mean follow-up time was 9.9 years (range 1.1–15.3). Endpoints reflecting uncontrolled CRSwNP were revision ESS, and need for rescue/advanced therapy (e.g. antibiotics, oral corticosteroids and/or biological therapy) during follow-up. NERD was variable of interest and gender, age, asthma, allergic rhinitis (AR), smoking, Lund-Mackay (LM) score of sinus computed tomography scans previous ESS and baseline total ethmoidectomy were used as covariates. Results Twenty-one (49.7%) NERD patients and 18 (25.7%) non-NERD patients underwent revision ESS within a mean ± SD of 4.3 ± 2.8 and 3.7 ± 2.6 years, respectively (p = .013, by Logrank test). In Cox´s regression models, NERD, female gender, young age, asthma, AR, previous ESS, and lack of total ethmoidectomy were associated with revision-ESS. In adjusted model, only the total ethmoidectomy predicted revision-free survival. In adjusted logistic regression model, there was an insignificant trend that NERD and LM score were associated with the need for rescue/advanced therapy in the follow-up. Conclusions Patients with NERD had higher risk of uncontrolled CRSwNP than patient group without NERD, as measured by revision ESS and/or need for rescue/advanced therapy in the follow-up. In addition, baseline total ethmoidectomy was associated with revision-free survival.

Total Pollen

Stigmatic pollen loads were analyzed from naturally pollinated pin and thrum form flowers of Amsinckia douglasiana and A. vernicosa var. furcata. Pin stigmas captured more total pollen than thrum stigmas. Pins experienced either net self-pollination or random pollination. Thrum stigmas experienced significant disassortative pollination. Comparing pollen loads from intact and emasculated thrum flowers of A. douglasiana indicated that self-pollination and geitonogamy were relatively unimportant in the pollination of the thrum form. The level of disassortative pollination of A. vernicosa var. furcata does not appear to be high enough to account for the level of disassortative mating observed by progeny testing, suggesting that this species may possess an incomplete stylar self-incompatibility system such as has been reported in A. grandiflora.

Introduction: We asked whether intracerebral hemorrhage (ICH) patients admitted to inpatient rehabilitation facilities(IRF) improve differently based on their involvement of the corticospinal tract(CST). Aim: To predict associating radiological factors affecting discharge FIM score. Methods: We reviewed the patients’ characteristics and their respective imaging findings presenting with ICH between 4/17 to 8/19. The ICH volume and edema around the ICH were measured using analyze software. The main outcome measure was FIM score at time of discharge. Statistical significance was set at 0.05. Results: Among the 53 patients included, 49% were female. The median age of the patients was 62 years (IQR 25,89). The median length of stay at IRF was 22days (IQR 14,26). In univariate analysis, FIM score at the time of discharge FIM score at the time of discharge admission were significantly associated with NIHSS (estimate -1.26, p<0.001), and ICH volume (estimate -3.45, p=0.01). However, the univariate analysis did not reveal an association of age (estimate -0.15, p=0.4) and gender (estimate 0.207, p=0.97) with FIM score at the time of discharge.Multiple regression analysis reflected that the CST involvement had a decrement in functional improvement on FIM in comparison with patients with intact CST when adjusting for age ( p = 0.008), gender ( p <0.01), NIHSS at the time of admission ( p <0.01), and the ICH volume ( p =0.02). Conclusion: This preliminary study suggests that functional improvement declines in ICH patients with CST involvement.

Tanzania like many other developing countries is highly dependent on agriculture for income generation and job creation for its citizens. Because the sector is mainly composed of smallholder farmers, lack of finance remains the leading obstacle to development. This study seeks to determine factors that affect access to bank credit by smallholder farmers in the Mvomero District of Morogoro, Tanzania. The study used a cross-sectional design, with data being collected via the survey method. Purposeful sampling was used to obtain the respondents who fitted into the study objective. The data were analyzed using descriptive statistics and a logistic regression model. The Logit regression model in particular was employed to determine factors that affect smallholder farmers’ access to bank services. The study reveals that the value of assets invested in farming activities, education and gender are significant factors affecting smallholder farmers’ access to bank credit. Policy recommendations include the establishment of a government bank that would exclusively provide financial services to agriculturalists by establishing a credit guarantee scheme, and the development of new financial products by the banks that would cater to the needs of smallholder farmers. Key words: access, bank credit, smallholder farmers, logit regression

Background: Obtaining genuine informed consent from research participants in developing countries can be difficult, partly due to poor knowledge about research process and research ethics. The situation is complicated when conducting genomic research on a disease considered familial and a reason for stigmatisation. Methods: We used a Rapid Ethical Appraisal tool to assess local factors that were barriers to getting genuine informed consent prior to conducting a genetic study of podoconiosis (non-filarial elephantiasis) in two Zones of Ethiopia. The tool included in-depth interviews and focus group discussions with patients, healthy community members, field workers, researchers/Institutional Review Board (IRB) members, elders, religious leaders, and podoconiosis administrators who work closely with patients. Results: Most patients and healthy community members did not differentiate research from routine clinical diagnosis. Participants felt comfortable when approached in the presence of trusted community members. Field workers and podoconiosis administrators preferred verbal consent, whereas the majority of patients and healthy community members prefer both verbal and written consent. Participants better understood genetic susceptibility concepts when analogies drawn from their day-to-day experience were used. The type of biological sample sought and gender were the two most important factors affecting the recruitment process. Most researchers and IRB members indicated that reporting incidental findings to participants is not a priority in an Ethiopian context. Conclusions: Understanding the concerns of local people in areas where research is to be conducted facilitates the design of contextualized consent processes appropriate for all parties and will ultimately result in getting genuine consent.

Aim of study: Indigenous woody species play an important role as a complement on the diet of rural populations in Niger, especially in periods of food scarcity. However, these species are nowadays overexploited and management programmes are necessary to conserve them. In order to design a conservation programme for edible woody species, this paper presents a sociological analysis about the use of edible woody species and their products during shortage periods in Niger.Area of study: Four villages in two distinct agro-ecological regions were selected to conduct structured enquiries based on focus group discussions and surveys with key informants.Material and Methods: Perceptions of the conservation status of these species were identified; as well the factors affecting food values, perceptions, management and collection practices.Main results: Results show that B. senegalensis was a staple food in the driest areas, and M. crassifolia was used for fodder and human consumption in the most critical situations. The local communities related the drivers of species conservation status specific to the agro-ecological regions, and gender and ethnic differences were also identified.Research highlights: Understanding these factors constitutes a first step towards adaptive management strategies for the conservation of woody food species in rural communities of Niger.Keywords: Africa; biodiversity; cultural preferences; food; NTFPs.
