Experimental studies on the pathogenicity of Vibrio mimicus strains isolated in Bangladesh
Vibrio mimicus, a newly described species of the genus Vibrio has been isolated from stools of 14 patients with diarrhoea. Live cells of all the 14 strains tested caused accumulation of fluid in rabbit gut loops and diarrhoea in infant rabbits. Culture filtrates of all the strains caused increased capillary permeability in rabbit skin; however, five of the filtrates resembled cholera toxin in that they gave positive reactions in rabbit loops, chinese hamster ovarian and mouse adrenal cell monolayers and GM1 ELISA tests and were neutralized by cholera antitoxin. None of the strains produced heat-stable toxin or possessed invasive capability as determined by Sereny's test. Thus, V. mimicus strains were divided into a group which produced a toxin immunobiologically similar to cholera toxin and the rest producing a heat-labile toxin unrelated to that of V. cholerae
FR1.2: Understanding Community Perceptions of Women Empowerment for Agricultural and Rural development
The concept of women empowerment has been widely embraced in development efforts aimed at achieving gender equality outcomes. However, intended outcomes are not always achieved due to a disconnect between how the concept of women empowerment is perceived by target communities and development actors. An understanding of how targeted communities perceive women empowerment helps development actors design context specific women empowerment approaches suited to prevailing social cultural norms and perceptions of men and women. This study therefore aims at understanding perceptions of women empowerment by local communities in rural farming villages of Kiboga district in central Uganda. A qualitative case study design was used to collect data on community perceptions about women empowerment through key informants and sex-disaggregated focus group discussions. The data were coded using Atlas Ti and analyzed to identify themes. We found that men perceived an empowered woman as un-submissive, and a competitor to men's household head position. To women, an empowered woman was perceived as un-submissive, hardworking and taking over culturally assigned men's household responsibilities. As women get empowered, what do men become and at what cost to women? Findings indicate that an empowered woman takes over the responsibilities of an "ideal man" and this adds work burden to women and a backlash from men. In order to counter this, development agencies should target men and women and invest in interventions and approaches that transform local gender norms that dis-empower women. The study is ongoing and further data collection will be completed in August 2022
TH2.1: Understanding femininities: Implications for women's Participation in Agricultural interventions in central Uganda
Research has documented how men's behaviors in patriarchal settings affect women's economic empowerment outcomes, while less attention has been paid to how gender identity constructions around femininities influence these outcomes. We define femininities as gender based roles and expected behaviors of women in a given community and economic empowerment as women's decision-making regarding access and control of productive resources and management of income. This paper presents research on how female and male farmers in rural communities of central Uganda define what it means to be a woman and how those identity constructions influence women's economic empowerment. This qualitative case study is based on focus group discussions conducted with Sasakawa Africa Association intervention farmers (28 women and 25 men) of Kiboga District. Six focus group discussions were conducted, two with men only, women only, and both men and women respectively. Findings reveal co-existence of traditional and progressive femininities, dubbed "unruly" by men and some women. Traditional femininities were depicted as women complying to community values which deter them from financial decision making and owning productive resources. Progressive femininities on the other hand are noncompliant to these community values, and enjoy more economic empowerment. Men valued economically empowered women because they relieve men of financial responsibilities. Incorporating gender transformative approaches in women's economic empowerment interventions could decode traditional femininities and increase women's intrinsic agency within the context of economic empowerment
Epilepsy care during the COVID-19 pandemic
The coronavirus disease 2019 (COVID-19) pandemic has affected the care of all patients around the world. The International League Against Epilepsy (ILAE) COVID-19 and Telemedicine Task Forces examined, through surveys to people with epilepsy (PWE), caregivers, and health care professionals, how the pandemic has affected the well-being, care, and services for PWE. The ILAE included a link on their website whereby PWE and/or their caregivers could fill out a survey (in 11 languages) about the impact of the COVID-19 pandemic, including access to health services and impact on mental health, including the 6-item Kessler Psychological Distress Scale. An anonymous link was also provided whereby health care providers could report cases of new-onset seizures or an exacerbation of seizures in the context of COVID-19. Finally, a separate questionnaire aimed at exploring the utilization of telehealth by health care professionals since the pandemic began was available on the ILAE website and also disseminated to its members. Seventeen case reports were received; data were limited and therefore no firm conclusions could be drawn. Of 590 respondents to the well-being survey (422 PWE, 166 caregivers), 22.8% PWE and 27.5% caregivers reported an increase in seizure frequency, with difficulty in accessing medication and health care professionals reported as barriers to care. Of all respondents, 57.1% PWE and 21.5% caregivers had severe psychological distress (k score >13), which was significantly higher among PWE than caregivers (p<0.01). An increase in telemedicine use during the COVID-19 pandemic was reported by health care professionals, with 40% of consultations conducted by this method. Although 74.9% of health care providers thought that this impacted positively, barriers to care were also identified. As we move forward, there is a need to ensure ongoing support and care for PWE to prevent a parallel pandemic of unmet health care needs
Effectiveness of self-financing patient-led support groups in the management of hypertension and diabetes in low- and middle-income countries: systematic review
OBJECTIVE: There is insufficient evidence on the role of self-financing patient support groups in the control of blood pressure (BP) and/or diabetes in low- and middle-income countries (LMICs). We conducted a systematic review to investigate the effectiveness of these groups in BP and glycaemic control. METHODS: We searched PubMed, Embase, SCOPUS, Web of Science, Global Health, African Journals Online, CINAHL and African Index Medicus for published peer-reviewed articles from inception up to November 2021. Grey literature was obtained from OpenGrey. Studies on patient support groups for hypertension and/or diabetes with a component of pooling financial resources, conducted in LMICs, were included. Narrative reviews, commentaries, editorials and articles published in languages other than English and French were excluded. Study quality and risk of bias were assessed using the National Institutes of Health Quality assessment tool and the revised Cochrane risk-of-bias tool. Results are reported according to PRISMA guidelines. RESULTS: Of 724 records screened, three studies met the criteria: two trials conducted in Kenya and a retrospective cohort study conducted in Cambodia. All studies reported improvement in BP control after 12 months follow-up with reductions in systolic BP of 23, 14.8, and 16.9 mmHg, respectively. Two studies reported diabetes parameters. The first reported improvement in HbA1c (reduction from baseline 10.8%, to 10.6% at 6 months) and random blood sugar (baseline 8.9 mmol/L, to 8.5 mmol/L at 6 months) but these changes did not achieve statistical significance. The second reported a reduction in fasting blood glucose (baseline-216 mg/dl, 12 months-159 mg/dl) in diabetic patients on medication. CONCLUSION: Self-financing patient support groups for diabetes and hypertension are potentially effective in the control of BP and diabetes in LMICs. More studies are needed to add to the scarce evidence base on the role of self-financing patient support groups
Detection of monoclonal immunoglobulin heavy chain gene rearrangement (FR3) in Thai malignant lymphoma by High Resolution Melting curve analysis
<p>Abstract</p> <p>Malignant lymphoma, especially non-Hodgkin lymphoma, is one of the most common hematologic malignancies in Thailand. The diagnosis of malignant lymphoma is often problematic, especially in early stages of the disease. Detection of antigen receptor gene rearrangement including T cell receptor (TCR) and immunoglobulin heavy chain (IgH) by polymerase chain reaction followed by heteroduplex has currently become standard whereas fluorescent fragment analysis (GeneScan) has been used for confirmation test. In this study, three techniques had been compared: thermocycler polymerase chain reaction (PCR) followed by heteroduplex and polyacrylamide gel electrophoresis, GeneScan analysis, and real time PCR with High Resolution Melting curve analysis (HRM). The comparison was carried out with DNA extracted from paraffin embedded tissues diagnosed as B- cell non-Hodgkin lymphoma. Specific PCR primers sequences for IgH gene variable region 3, including fluorescence labeled IgH primers were used and results were compared with HRM. In conclusion, the detection IgH gene rearrangement by HRM in the LightCycler System showed potential for distinguishing monoclonality from polyclonality in B-cell non-Hodgkin lymphoma.</p> <p>Introduction</p> <p>Malignant lymphoma, especially non-Hodgkin lymphoma, is one of the most common hematologic malignancies in Thailand.

Analyzing DNA extracted from formalin-fixed, paraffin-embedded tissues by multiplex PCR techniques is more rapid, accurate and highly sensitive. Measuring the size of the amplicon from PCR analysis could be used to diagnose malignant lymphoma with monoclonal pattern showing specific and distinct bands detected on acrylamide gel electrophoresis.

This technique is highly sensitive and can detect 0.5-1% of clonal lymphoid cells. It measures the amplicons by using various fluorescently labeled primers at forward or reverse sides and a specific size standard. Using a Genetic Analyzer machine and GeneMapper software (Applied Bioscience, USA), the monoclonal pattern revealed one single, sharp and high peak at the specific size corresponding to acrylamide gel pattern, whereas the polyclonal pattern showed multiple and small peak condensed at the same size standard.

TH2.1: Who is a man? Understanding the local normative climate for transformative interventions in rural farming communities of Central Uganda
Local gender normative climate refers to how norms in a community interact with men and women agency- their ability to make strategic life choices. Understanding the normative climate includes unpacking the community's expectations of what it means to be a man "masculinity norms". Such normative factors interact with and constrain opportunities for women's equitable participation in agriculture, yet most women empowerment literature focuses on individual women level factors. This ongoing study aims to determine masculinity norms that affect women's ability to make strategic choices within the Sasakawa Africa's Nutrition sensitive agricultural extension project intervention areas in Kiboga District, Central Uganda. The study utilized an interpretive qualitative case study with data collected from sex disagreggated focus group discussions with intervention beneficiaries. Findings indicate that the community expectation of who a man should be are along family formation and provisioning; dominance in household decision making and leadership; and community level participation. The normative structures also exempted men from participating in domestic chores and negative sanctions were experienced by men that did so. Gender roles espousing notions like "vegetable growing is a woman's domain" dissuaded men's engagement in this activity. Consequently, domestic chores on top of additional activities from vegetables growing under the project present an increased labor burden for women. Inability to make strategic life choices like attending training that would build their capacities in areas important for their development curtails their economic investments. This calls for development agents' deliberate efforts to engage both women and men to reframe norms and new behaviors that will foster gender equality and a harmoniously transformed community
TH2.1: Empowerment without Transformation? A Scoping Review on Women Empowerment, Masculinities and Social norms in Agricultural Research
There is an increasing focus on re-thinking women's "empowerment" strategic interventions in order to achieve meaningful transformation in gender norms. This move is increasingly characterized by initiatives that deliberately seek to engage women and men, highlighting not only how women's lives in agricultural communities are interwoven with men's lives but also calls for ‘involvement' of men in women's empowerment work to address the underlying social norms, attitudes and behaviours that perpetuate gender inequalities. How have social categories "women", "men" and notions of empowerment and masculinities been conceptualized in agricultural research on women's empowerment? How have these concepts been deployed in agricultural research and with what implications? This paper draws from a literature review. Search terms included "Women's empowerment", "masculinities", "gender norms", "agency" "Power relations", "Rural masculinities" "male involvement in agriculture". Drawing on literature within agri food system, seed systems, nutrition sensitive agriculture in different regions of Africa and Asia, the paper argues that conceptualization of categories women, men, masculinities and femininities and the approaches drawn therefrom (the assumptions we work with about women and men) have potential to transform and/or reproduce unequal gender power relations
